Potential Deficiency of B1W IE Instrumentatiori ~nd Control Cables

Cr:nt J Pmen:

United Energy Services Corporation {UESC) is an engineering services company, under contract to a number of utilities in the u.s. and Canada to address Environmental Qualification (EQ) for equipment which is important to safety.

In the course of performing our analysis, we have identified additional information which relates to the issues raised in NRC Information Notice 93-33, "Potential Deficiency of Cf•rtain lE Jnstrumr:ntat.ion and Control Cables," spE~cifically for BIW caliles. Our analysis of various EQ test reports by BIW has caused us to question BlW's aging methodology in their reports, to the extent that W(' havf\ stopped using the activation energies derived from aqinq d;itil in those reports. We have also advised all of our utility ,·ustomers to reevaluate any of their EQ files which may have u~ed this data.

Because of the age of these BIW test reports, and their lack of detail, we are unable to verify our concerns or further evaluate the potential of 10 Cfl< 21 implications. Therefore, we are forwarding the enclosed analysis for you to evaluate for possible invesUgation at BIW. If you have any questions or need further i nf ormation, plt!ase contact Mr. Jerry Henley in this off ice at (20~1) 922-0700.

Ret: HlW Reports 8912, 891~, and B916 Aging Methodology

Dear Mr. Henley,

April 1:>, l<J'-Jl

1 have reviewed the Telephone contact Report attached to your Apr i 1 1 3 FAX, and should 1 ike to advise that I am in genera 1 agreement with the substance of that report. However, there are a couple ot m1nor points which should be clarified.

1. Para I.

Chang(~ the 4th sentence to read as fallows. "The elongation tests showed basically the same aging rate (slope) regardless of thP value of elongation selected." It should be clarified that this was true for a range of elongation values which varied with the particular compound being tested. The upper elongation values were ~00% for the EPR insulation of Report 8915, and 350% for the FH-XLPE of Reports 8912 and 8916. For both materials, aging lines were drawn for 50% and 0% elongation based on a regression analysis. However, in practice it is almost impossible to actually measure such small elongations, so they 1.:-an only be obtained from th(-"' regression lines.

2 Para 3.

Change the Jrd sentence to read as follows. "Mr. Jeanmonod admitted that he could not justify the conservatism of BlW's selection of a flame retardant material to represent a non­flame retardant material." The aging line in Report B912 was obtained from tests on FR-XLPE, but the coaxial and triaxial cables covered by this report are insulated with non-flame retardant XJ.PF.

DISCOSSIOlf:

Mr. Jeanmonod was very helpful and provided the following information concerning 8IW cable tests in the mid to late 1970's:

There was disagreement among cable manufacturers at that time about which Arrhenius failure parameter was most applicable to natural aging of cables in service. As a result, BIW elected to perform two types of aging tests. First, they performed elongation tests on aged coupons of materials to draw the Arrhenius curve (standard IEEE method). The elongation tests showed basically the same aging rate (slope) regardless of the value of elongation selected up to lOOl. Second, they tested complete cables (conductor, insulation, shield, fillers, and jacket) by aging them at five different temperatures and periodically withdrawing them for subjection to a 2,200 VAC dielectric withstand test. This aging, removal from aging, and dielectric withstand test cycle was repeated for durations up to and beyond what the elongation curve predicted as a 40-Jear life and resulted in the data points shown on the plots. Since dielectric withstand is accepted as proof of a cable's integrity, this showed the cables had considerable useful life beyond a 40-year life predicted by the Arrhenius curve.

The Arrhenius curves in both 8IW Reports 8915 (EPR) and 8916 (CLPE­FR) were derived from testing on coupons of the exact material compc:.md as the cable insulation addressed in the report. However, Report 8912 (CLPE-NFR), on coaxial and triaxial cables, used a CLPE-FR material to draw the Arrhenius curve. Mr. Jeanmoncd admitted that he could not justify the conservatism of BIW' s selection of a non-flame retardant material to represent a flame retardant material.

Supporting data and notes from the period of testing are sketchy but may be available through a search of the company archives. John had a limited amount of data available to him in addition to the test report, but he had a good recollection of the tests since he was personally involved in the testing programs at that time. He said he was willing to ~onfirm these facts in writing.

Contact Report of J. Henley to ,John Jeanaonod, BIW cable systems April 12, 1993 Paqe 2 of 2

John said they have had no significant questions from the nuclear industry regarding their methodology (everyone seems to agree with it), but they have had many questions about the B912 report's use of the flame retardant material test data for the non-flame retardant. They have no data for the non-flame retardant material. The decision was made years ago not to perform that testing.

Mr. Jeanmonod stated that he had mailed me a letter to clarity the above points. He stated that the clarifications were simply to put the facts into perspective and not contradictions.

Mr. Jeanmonod provided the following additional information as clarification on BIW Report No. B915, pages 5-8:

1. There is no significance to the fact that B915 is the only BIW Cable Test Report that includes Figures 2A and 2B. These figures present data that is from the same testing as stated on page 5 of the report.

2. The parameters in Figures 2A and 2B are differ~nt repr.esentations of the same elongation test data. The percent elongation in Figure 2B represents the ratio of length at break to or i gina 1 1 ength given as a percentage. The percent remaining elongation in Figure 2A represents a percentage of elongation remaining but normalized to 100% In fact, the actual length of unaged EPR at break would approach 700% of the unstretched length.

3. Draka probably would not have a problem with someone paying "a modest fee" to research their BIW Cable Systems archives to find any additional data. If the data can't be found in 2-3 days, it probably doesn't exist.

Possible Reportable Event BIW Cable - Report Mo. UESC 21-01

1. I have reviewed the subject report and investigated the circumstances surrounding the source documents which are the object of the report. This memorandum will be attached to the report as support information for the determination in Part C that reportability of the event is D.Q.t.~stablished because there is a lack of data available from the manufacturer.

2. Stat.uept of the f[QI:»l!IIZ. Part A3 gives the description of the non-compliance or defect as, "In the System 1000, the Arrhenius data on BIW cable is unsubstantiated and, as indicated by attachment to the above reference, is non-existent."

Part A4 of the report describes the hazard created by this non­compliance as, "BIW cable lite cannot be predicted for any environment. Life cannot be calculated from BIW supplied data. Therefore cables may fail prematurely or in an accident environment."

Exhibits a through d formed the basis for the report of the possib]@ reportable event. Exhibit b originally identified four BIW Cable Test Reports (Exhibits h, i, j, and a) which used unsubstantiated data as a part of the deteraination of a 40-year qualified life. Excerpts from these reports are used in the System 1000 Ljhrary Cod@ Number 060-838 (Exhibit e) to derive activation energies for use in predicting an end-of-life condition or for calculating demonstrated qualified life for these materials in safety-related applications. Exhibit c added another BIW Cable Test Report (Exhibit k) as also having unsubstantiated data of the same type.

During the course of the investigation, additional BIW Cable Test Reports (Exhibits q and 1) were located. Exhibit q uses the aaae aging methodology as Exhibits h, 1, j, and m. Exhibit 1, however,

••or•adu.a J. Ben ley to .M. limb.t ell tt.pril 16, 19tJ Pa9• 3 of 7

uses Arrhenius data provided by DuPont tor Tefzel, and applies that data in the generally accepted manner to determine aqinq times for placing cables in an end-of~life condition.

Additional BIW cable aging data, in the form of an Arrhenius plot tor Silicone Rubber cables, was provided in a letter from BIW, which was used as an input to the System 1000 Library Code Nu.ber 121-91 (Exhibit f) to derive an activation energy. This plot also shows points along the Arrhenius line which represent a 50t loss of elongation and were used t.o derive the activation energy.

To summarize, there are eight documents from BIW (seven BIW Cable Teat Reports and one letter) which have been identified durin, this investigation as providing insiwht into BIW's aging aethodoloqy. Six of these documents (Exhibits g through k and II) present the same or similar methodology. The seventh document (Exhibit f) trans11ita actual data points tor an established failure paraaeter (50\ loss of elongation) and the eighth docuaent (Exhibit 1) presents aging data provided by a material supplier (DuPont Tefzel). Both of these latter two docuaents present data in a manner traditionally accepted by the i.ndustry and published IEEE standards such as IEEE 101.

The methodology for the six BIW Test Reports which are the same or similar was identified in an attachment to a letter from BIW (Exhibit n) and identifies a potentially unsafe application of the Arrhenius theory of aging. Although the derivation of the Arrhenius data does conform to accepted practice, Sections 2.5 and 2.6 describe the application of the line which apparently was used in the six BIW Test Reports identified above. The aethodoloqy allows tor the use of a line with the same slope as the Arrhenius line drawn through the point representinq a 40-year life at 90~. Then cables are thermally aged at various temperatures and periodically withdrawn for subjection to a dielectric withstand test at 2,200 VAC to demonstrate acceptabiljty. This methodology purportedly demonstrates the conservatism of aging to the line for a 40-year life.

All of the six BIW Ter.t Repr;rts apparently used this basic methodology, testlng Ln~ oasic insulation for elongation, shifting this line to pas• throu~n the •v-year at 90°C point, and then aging complete cables at several temperatures, withdrawing them periodically and testing for dielectric withstand at 2,200 VAC. In at least one BIW Cable Test Report (Exhibit h), however, a flame retardant crosslinked polyethylene was used to represent a non­flame retardant polyethylene material. Verbal confirmation of this difference was obtained in Exhibit o, but Draka Intercable

••oraadua J. Henley to M. Jt.imbrell April 16, lttl Pat• • of 7

(formerly BJW Cable systems, Inc.) has not c:ontirmed this in writing to date.

The shifting of the Arrhenius line is justified in one of the BIW Cable Test Reports (f~xhibit. i), based on a stateaent that the resulting Arrhenius plots tor various values of retained elongation were •essentially straiqht and parallel." This saae justificati.on was also presented verbally in Exhibit o tor two other BIW Cable Test Reports (Exhibits i and j). Exhibit i is unique aaonCjJ the six BlW Cable Test Reports in that it presents elonqat ion curves as well as the resulti.nq Arrhenius plots (all of the other BlW Cable Test Reports only give the final Arrhenius line which passes throuqh the 40-year at 90°C point). This additional data may qive insight to the application of the BIW aqinq aethodology and the central issue for the possible reportable event.

Reduction of the data presented in Fiqure 2A ot Exhibit i apparently does not result in the plot shown in Fiqure 3, as BIW states that. it does on page 5 of Exhibit i. Calculations of the activation energy reading the data from Figure 2A and using the Systea 1000 for activation enerqy detenllination show the following results:

25\ 50t 75%

0.92 ev 0.96 ev 0.98 ev

'l'hese activation energies are significantly less than that shown by the Arrhenius plot in Fiqure 3 which is calculated by the System 1000 as E, • 1.14 ev. Thereto; , it does not appear that the data in Figure 2A can be used to generate the same activation energy as that shown on Figure 3.

The possibility exists that BIW used the elongation data from Figure ?.A to plot an initial Arrhenius line, then shifted this line manually to the left to pass throuqh the 40-years at 90°C point. If so, the resulting line represents something beyond the end-of­lite condition that the data in Fiqure 2A would support. For example, the data fro11 Figure 2A for 75l loss of elongation in fact only supports approximately a 4.9-year life at 90°C (Exhibit p).

By uainq the Arrhenius line derived fro• elongation tests and plotting the results of dielectr·:c withstand tests, BIW's aging methodology compares mechanical properties with electrical properties. Electrical properties typically do not correlate well

••or and ua J. Ben 1. •Y to M. l i.liliJ: ell ~pril 16, 1tt3 Paqe s of 1

for cable performance in service. Re(.:ent.ly, this tact. was confirmed by SAND91-1766/2, which tested the same BlW Bostrad 7E EPR/CSPE cables, among other EPR cables, under aqinq and accident conditions. Page 2 ot this report concluded that "elon<Jation is the best condition monitoring method", and also that "electrical measurements were not effective for monitoring residual life ... Therefore, the data points from dielectric withstand testing above the shifted Arrhenius line does not indicate a siqnificant amount of conservatism in the cable design, if any.

In view of this difference between activation enerqies derived from electrical properties and activation energies derived for mechanical properties, it is significant to note that the data points indicating electrical failures for BIW EPR/CSPE cables in BIW Cable Test Report 8910, Figure 2 (Exhibit q) form a line with a much lower slope than the Arrhenius line which passes through the 40-years at 90°C point. The System 1000 calculates an activation energy of Ea • 0.63 eV for the three failure points, which are all above the drawn Arrhenius line (Exhibit p).

Therefore, this investiqation reveals that the six BIW Cable Test Reports which seem to support the same methodoloqy may have a fundamental misunderstanding between the meaning of an end-of-life condition and the accelerated aging rate. The application of this misunderstandinq, through usinq the acti vati.on energies derived from these reports, could result in an unsafe condition by the premature failure of safety related equipment.

Further investigation at Draka Intercable is required to retrieve backup data which can deteraine whether this is a reportable event under 10 CFR 21 and constitutes a substantial safety hazard. Since this issue has a large potential impact upon the qualification of BIW cables at a large number of u.s. nuclear plants, it is recommended that the NRC pursue the evaluation with Draka Intercable.

As a precaution pending further investigation, UESC will withdraw all BIW aqing data in the System 1000 (Library Code Numbers 060-838 and 121·91, Exhibits band c, respectively), notify all customers of the System 1000 of the withdrawal of this data, and ask them to assess the impact, if any, on their safety related equipment. UESC will also attempt to determine the use of the activation energies from these Library Code Numbers and contact the affected client(s), if any.

3) Note To R.A. Gray from M.D. Sterian Dated 31 March 1993, Subject: Environmental Qualification of BIW Coaxial Cable.

In further investigatjon of this concern with our customer, Ontario Hydro, we were notified that through a contact they had with BIW, they learned that the Arrhenius line presented in the BJW test reports does not show relevant data. The line drawn through the 40 year point is parallel to a line based on testing BlW performed on PE (Polyethylene) to a predetermined change in elongation. The "Arrhenius" testing that is presented in the BIW test report(s) is based on an electrical property of the material (in this case XLPE- crosslinked polyethylene).

This leads to the conclusion that the Arrhenius line presented by BIW is not only based on a totally different property than that on which the aaterial test data in the report is based, but it is based on a coapletely different 11aterial (PE Vs. XLPE). See the enclosed letter (Reference #3) with the appropriate paragraphs circled.

Based on this, it is recommended that all Arrhenius data presented by BIW in their test reports should be thoroughly questioned, if not totally eliminated, from System 1000.

SUBJECT: Unjustified Boston Insulated Wire (BJW) Arrhenius Data in the System 1000 Database

'l'be assessment for BIW Xl.JlE insulated coax cable at OHIS NGS ( 5. ex. 01) uncovered certain System 1000 database errors and unsubstantiated data from the cable manufacturer. Due to the uncertainty of the data, it could not be used in the assessment process.

Arrhenius plots are developed by testing at va.ri.ous temperatures until a pre­defined failure criteria is reached. In other words, an Arrhenius plot is generated based on failure points. The system 1000 "Arrhenius Data Calculation Worksheet•• tor BIW XLPE insulated cable with Chloroprene uses four analytical points as the "time to tai Jure" points to generate the Arrhenius data (Attachment 1). These tour points (Yl through Y4) &r~ not failure points. These points are in fact random points in time where the test samples were removed from the oven, subjected t:o a dielectric proof test ot 2200 volts, then after successfully passing the test returned to the oven for continued aging (Attachment 2, third paragraph). Therefore, the System 1000 data entry points do not represent an Arrhenius relationship but appear to be a "backfit" to an arbitrary line. This is an unacceptable practi.ce and the System 1000 database entry is invalid.

The pre-existing Arrhenius line appearu in BIW Reports B9l2, B915 and 8916 (Attachments 3, 4 and 5 respectively). In each instance, there is a note stating "slope derived from prior aging test data". This prior data has not been provided to date (requested from BIW). Additionally, the lines in all three cases are parallel. This depicts the same slope and activation energy for each material which is highly improbable due to the differences between Flame Retardant Crosslinked Polyethylene Insulation with Neoprene/CSPE Jackets (Report B912), Ethylene Propylene Rubber Insulation with CSPE Jackets (Report 8915), and Flame Retardant Crosslinked Polyethylene Insulation with Neoprene Outer Jackets only (Report 8916). The validity of the sue Arrhenius line being applicable to all the different materials is highly questionable.

'I'he B 1 W Arrhenius J i ne remains unsubstantiated and .is ouspect to t·emain so. Considering the short amount o1 time available, it is recommended that OH Research Lab proceed with Arrhenius testing on the BIW Coax cable in ot·der to determine an activation (•nf.>rqy value tor the insulation and the jacket protecting the shield. Once these values are detPnnined, the aging and accident simulation data in t hP BlW report~ can bt: US(~d to quality the coax.

1~. 40 YEAR LIF£

£vidence of 40 yetr 11ft 1t 90C 1s shown by the following 1nform.tion and figure 2 for RJ1t1conductor cc1bles with 1 fllllt retardant trade of eros•­linked polyethylene ir.sulet1on. Although tht crosslinked polyethylene on coa~ial and tr1ta111 clb1es 1s not • fl ... rttlrdant grtde, its lift ts c~arab le to that of the flafftf retardant 9rtdt. This 1S being conf1 rwd by aging tests now in pro9re~s o~ coa•1al cables.

The test progratlll conducted •or the flame retardant gra::te 1nd presently underway for the co1x1a1 and triu111 grade of crosslinlced polyet.,ylene in-

sulation is descr1be1 below.

8!W's cross11nked polyethylene 1nsulat1on has an indicated l1fe of over 40 yeari at 90C according to ag1ng tests currently in progress. Test dtta are being evtluated by the Arrhenius technique, using a slope determined by aging tests previously conducted by BIW. When thE' aging slope 1s dtter­m1ned for meterh1, a 40 year condition 11f'e can be established at t .. 1~ serv1ce ~rature, as shown on Ftgure 2.

Aging of BIW's flame retardant cross11nked polyethylene is betng conducted at f1ve temperatures: 200C, lBOC, 136C and 121C on 2/C and 7/C cable samples. The cables hove heavy-duty neoprene overall jackets. The data on Figure 2 show that the 1nsuiati'n is intact, and cables are operable up to and above tt.l:! ,·equi red aging times at 200C, 180C, 150C and 136C, since any point on the curve represer.ts the equivalent of 40 years life Dt 90(. Tests are made periodica1 1y lt twice raterl voltagE' plu~ l,COO volt~ cr 2,20G volts, between condu,·tors and be·ween conductors and shield for these nOO volt cables. When the agin9 reaches tht 40 year liff' curve, the cable~ are straightened out, given a 40x bend, straightened out aga1n and tested iit 2 ,2CO volts.

NOTE· l!St levf'l is tQOO v0lt~ on coaxial cables w1th rrosslinked polyethylene insulaUon.

With the indicated life of at least 40 ye•rs at 90C already proveu at lOO(. 180C, 150C and 13~C. 1t 1s to be e~pected that the aging data still 1n pro­gt~ss at 121C w11. further substantiate this performance. We might point out that since data on other insulations show that a test voltage ot 1,200 volts or less 1s suffic1e~t to detect cr!ck~ or flaws, passing at 2,200 volts shows excellent 1nsuiation integrity.

IV. 40 YEAR LJ FE

BIW's ethylene pr-opylene rubber insulation/ Bostrad 7 chlorosulfonated polyethylene jacket system has an indicated life of over 40 years at 90C according to ag1na tests curr~1tly in progress. Test data are being evaluated by the Arrhenius technique, using a slope determined by aging tests previously conducted by BIW. When the aging slope is determined for a matert.al, a 40 year condition line can be established at the service temperature, as shown on Figure 2.

Aging or BIW's ethylene propylene rubber/ Bostrad 7 chlorosulfonated polyethylene is being conducted at five temperatures: 200C, l80C, 150C, l36C and l21C on 2/C and 7/C shielded cable samples. The cables have heavy-duty Bostrad 7 chlorosultonated polyethylene overall jackets . The data on Figure 2 show that the insulation is intact, and cables are operable up to and above the required aging times at 200C, 180C, 150C and 136C, since any point on the curve represents the equivalent of 40 years life at 90C. Tests are made periodically at twice rated voltage plus 1,000 volts, or 2,200 volts, between conductors and between conductors and shield for these 6oo volt cables. When the aging reaches the 40 year life curve, the cables are straight­ened out, given a 40x bend, straightened out again and tested at 2,200 volts.

With the indicated lite of at least 40 years at 90C already proved at 200C, 180C, 150C and 136C, it 1s to be expected that the aging data still in progress at l21C will further substantiate this performance. We might point out that since data on other insulations show that a test voltage or 1,200 volts or less is sufficient to detect cracks or flaws, passing at 2,200 volts shows excellent insulation integrity •

At:cel•rated •·Jln•,l on •dabs ot crosslinked polyethylene was performed ooy the Arrhentus technique at five test temperatures. The slope of the Arrhenius curve wao tound to be Identical for any end cond!E1on. Because the slope is constant, a line using this slope can be constructed through the point representing 40 years an~ 90°C and any point on this line will be equivalent to a 40 year, 90 C life (Figure 2) •

Material tXpe tests gn multi-conductor cables aged at 200°c, 180°c, 1S0°c, 136 c and 121 c show a projected life on the Arrhenius plot in Fi9ure 2 of •o years at 90°C with considerable mar;in as represented by the passing points above the line. The cables were removed from the oven periodically and subjected to a dielectric proof test of 2200 volts (twice rated voltage • 1000 volts). After successfully passing the test, the samples were returned to the oven for continued aging. As the data In Figure 2 clearly indicate, the cables pass a bend test after aging to the equivalent of 40 years at 90°C and continue to pass upon additional aging.

Life of 40 years at 90°C tor the crosslinked polyethXlene Insulation A• additionally confirMed on coaxial cables aged at 150 C, l21°C and 110 C, Fi9ure 2. These cables were tested at 3500 volts (rated voltage + 1200 volts). Mechanical considerations preclude accelerated agtng of coaxial cables at higher temperatures.

Figure 2 is offered as evidence of 40 year life at 90°C. Figure 2A

SinCe a rate of aging has been doteralned for the Insulation (&lope of llnm In Figure 2), then for any defined service condition, e line having the predoterelned aging rate (slope) can be constructed through the point representing the service condition, and all points on the line will be equivalent to the defined servtee condition. In Figure 2A, Lines B and C have the saae slope (rate of aging) ~s Line A from Figure 2. Consequently, cables aged for 668 hours at 121 C as In Figure 3 have • projected Alfe of 40 years at 54 C (Line C) and cables aged for 168

0 hours at 150 c as In Figure 4 have a projected life of 40 years at 74 c (tine B).

Single Conductors Broken Out of Multiconductor Cables -Sacrificial Jackets

BIW has successfully conducted LOCA tests on both s1n~le conductor and multiconductor cables. The jacket on a multi conductor cable serves as mechanical protect1on during installation end we acknowledge that it may be damaged during thenmal conditioning or simultted OBE's. The cables w111 function electr1ce11y without the outer jackets.

fvidencr:· of single conductors successfully passing OBl qualifi<.ation tests is shown by figure 8, page 17 in Report B915 and by the attached Reports 76C009 for a 1/C 112 AWG (aL1e and 758025 for a 1/C 16 AWG cable. The jackets on 1/C cables also undergo damage during testing and are not r·equired for the electrical operation and the cables t~till function electrically without the jacket. This serves as t>vidence that the individual conductors of a multiconductor catle will also function electrically without jackets.

Item 7 Figures 15 and 16 ;n Report 891& show that unaged cables have excellent perfonmance properties after long term immersion for 48 weeks ( 336 days) in 90°C water by the e 1 ec troendosmos is nlf'thod and 52 weeks (364 days) in 75°C water by the lM-60 method. Long terni water ilflllersion tests are typically perfonned only on unaged cables.

As shown by Figure 7 in Report 8915, a cab 1 e aged to the equivalent of 40 years at 90°C (figure 3, Report B915) performed well throughout the period of 161 days in LOCA during which time the cable was continuously in contact with moisture. The boric acid spray was applied for the first 24 hours and mineral-free water was applied there­after through 161 days. Afaer aging to the equivalent to 40 years at 90°C, 2 x 10 rads gamma radiation, and 161 days in contact with moisture during LOCA, the cable had sufficient elongation, after a 40X bend, to pass a 2400 volt a-c dielectric test for 5 minutes while immersed in water. This shows the excellent water resistance of aged and irradiated cables.

figure 8 in Report 8915, and Reports 76B025 and 76C009 furnish additional evidence of the ability of aged and irradiated cables to withstand a wet environment under the severe LOCA environmental conditions of IEEE 323 (Figure Al cycle for Reports 768025 and 76C009 and Table A2 cycle for Figure 8).

We certify that all test data in Report 8915 applies to the cables in P.O. N-18988. Report 8915 presents prototype test data for cables with the same insulation and jacket materials in strict accordance with lEE£ 383-1974 and IEEE 323-1974.

l. INTRODUCTION

LONG TERM AGING PROCEDURE FOR

1_EEE STANDARD_.]_§)

The method described in this procedure shows how accelerated aa1ng r ~~ ---

times and temperatures are determined for organic insulation systems. Thia method relates cable perfcrmance to actual service conditions and ia baaed upon the verification that the insulation material itself behaves in a manner Which pennita the uae of Arrhenius techniques.

2. VERIFICATION OF ARRHENIUS TECHNIQUE

Prior to the performance or any teats on cable apecimens, a lone term aging program is conducted to determine the behavior or the insulation material being considered. The details are given below.

2.1 Sample Preparation: A sufficient number of standard lSTM tensile bars are cut from molded sheets of the material in accordance with the procedures of ASTM ~12, Paragraph 12.

2.2 Sample Aging: The aaaplea are taken in aroupa of thrte and placed on wire hangers. The hangers are then placed in circulating air ovens at a minimum gr three temperature• at least 10 C apart, and including 136 C. The samples, again in groups of three. ere removed at suitable intervals. After a time period not to exceed 96 hours or leas than 16 hours, t~e tensile strength and elongation are measured and recorded. The teats at each temperature are carried out to zero elongation.

2.3 Sample Test1ns: Normal industry tensile teat methods for test1n& rubber and plaatic which employ crosshead apeeda of 20 lnchee per minute are only suitable for materials-having elongation• creater than 201. For this reaaon, a croashead speed or 2 inches per a1nute 11 uaed aa indicated in ASTH 0638 (Speed C) for eater1ala havtnc leas than 201 eloncetion. Results obtained using the lower speed ere represented by the broken line of Figure 1.

2.4 Plotttn& of Elonaation Curves: For each teat temperature the elongation of three samplea is plotted at each time interval until zero elongation is reached. Curves obtained for all temperatures are placed on 1 single greph, auch as that shown in Figure 2.

2.5

2.6

2.7

Arrhenius Plot: from the data as presented ln­second fam1ly of curves is plotted for constan elongation. This is shown on the Arrhenius plo 3. If the resulting lines are straight this is an indication of a constant rate of aging. The parallelism of the lines representing the different end points (elongation) indicates that the aging rate is constant aod independent of the particular end points. The linea must be both atraight and parallel if this method of determining preaging is valid.

Aging Plot for Cable: A line having the elope determined from Figure 3 is drawn through a defined end point such as ~0 years at 90°C. The line shown in figure ~ represents the time and temperature relationship equivalent to the end of life condition.

Cable Sample Pr·eparation: Prior to undergoing air oven aging cable samples having the insulation for which the Arrhen1us plot was developed are prepared in the following manner:

{a) The samples approximately 18 inches in length have 2 inches of jacket removed from each end and the insulation removed from 1/2 inch of each conductor. The conductora are then splayed out and held in this position by packing with uncured silicone rubber. This is done to prevent electrical test failures at the cable ends due to handling.

2.8 ~able Aging: Three cable samples are placed in circulating air ovens at three or more suitable temperatures at least 10°C apart, and including 136°C. These samples are removed at designed intervals and subjected to a dielectric test of twice the rated voltage plus 1,000 volts for one minute. At that time which corr~aponds to the Arrhenius plot for the test temperature the cable sample is given a bend around a mandrel having a diameter of 40 times the cable 0.0. It is then subjected to a dielectric test in water of twice the rated voltage plus 1,000 volta for one minute. If the cables aucceaafully withstand this test voltace after the bend they are put back in the oven and tested periodically until failure. Teat points are shown in Figure 4. It ia the intent of this procedure to demonstrate that cables aged to the equivalent of the end of life condition still w11 hatand the electrical test requirements.

DISCUSSION:

Mr. Jeanmonod was very helpful and provided the following information concerning BIW cable tests in the mid to late 1970's:

There was disagreement among cable manufacturers at that time about which Arrhenius failure parameter was most applicable to natural aging of cables in service. As a result, BIW elected to perform two types of aging tests. First, they performed elongation tests on aged coupons of materials to draw the Arrhenius curve (standard IEEE method). The elongation tests showed basically the same aging rate (slope) regardless of the value of elongation selected up to 100%. Second, they tested complete cables (conductor, insulation, shield, fillers, and jacket) by aging them at five different temperatures and periodically withdrawing them for subjection to a 2,200 VAC dielectric withstand test. This aging, removal from aging, and dielectric withstand test cycle was repeated for durations up to and beyond what the elongation curve predicted as a 40-year life and resulted in the data points shown on the plots. Since dielectric withstand is accepted as proof of a cable's integrity, this showed the cables had considerable useful life beyond a 40-year life predicted by the Arrhenius curve.

The Arrhenius curves in both BIW Reports 8915 (EPR) and 8916 (CLPE­FR) were derived from testing on coupons of the exact material compound as the cable insulation addressed in the report. However, Report 8912 (CLPE-NFR), on coaxial and triaxi.al cables, used a CLPE-FR material to draw the Arrhenius curve. Mr. Jeanmonod admitted that he could not justify the conservatism of BIW' s selection of a non-flame retardant material to represent a flame retardant material.

Supporting data and notes from the period of testing are sketchy but may be available through a search of the company archives. John had a limited amount of data available to him in addition to the test report, but he had a qood recollection of the tests since he was personally involved in the testing programs at that time. He said he was willing to confirm these facts in writing.

John said they have had no siqnificant questions from the nuclear industry regarding their methodology (everyone seems to agree with

contact Report of J. Henley to John Jeanaonod, BIW Cable systeas April 12, 1993 Paqe 2 of 2

it), but they have had many questions about the 8912 report's use of the flame retardant material test data for the non-flame retardant. They have no data for the non-flame retardant material. The decision was .aade years aqo not to perform that testing.
