NUCLEAR REGULATORY COMMISSION UESTIONS
Nine Mile Point Unit 1
Docket No. 50-220DPR-63
Question
Provide the details of the uranium-235 loading and distribution in thefuel assembly which were used for the spent fuel pool criticalitycalculations.
~Res ense
Figures 7 and 8 contained in the March 1978 submittal detail the fuelassembly model used in the criticality calculations. The fuel assemblyis comprized. of 64 0.64 inch by 0.64 inch cells containing homogenizedfuel, water and cladding. The fuel assemblies are assumed to be un-irradiated with an assembly average enrichment of 3.0 weight percentwhich is equivalent to a loading of 15.186 grams per axial centimeterof fuel assembly. A calculation, representing an explicit fuel pindistribution of selected U-235 enrichments typical of a 3.0 weight per-cent General Electric intra-assembly fuel pin arrangement is performedand included as a perturbation on the single average enrichment modelresults.
uestion
Provide the areal density of boron-10 in the Boraflex plates which wasused in the criticality calculations and provide the "quality assured"minimum value of .this areal density (i.e., atoms of boron-10 per squarecentimeter of Boraflex plate).
~Res onse
The boron-10 loading used for the criticality analysis was based on theminimum B4C loading of 34.8 weight percent in the Boraflex and assuming76 weight percent boron in the B4C powder. This corresponds to a boron-10loading in the minimum 0.10 inch thick Boraflex sheet of 0.0217 grams persquare centimeter of cross section area (0.0217 gm B-10/cm -0.1 inch).This represents the minimum areal density required by specification tobe incorporated into the as fabricated Boraflex plates. As a perturba-tion on the criticality calculation it was assumed t)gt the boron contentof the B4C powder was 70 weight percent (0.0200 gm B /cm2-0.1 inch),which represents an 8.5 percent reduction in boron-10 content of theBoraflex. Current production techniques indicate that the actualboron-10 loading in the Boraflex will be well above the 0.0217 gmB-10 value.

3. Question
Provide the calculated change in the storage lattice k~ with a smallchange in the boron-10 concentration in the Boraflex plates.
~Re onse
The calculated change in the storage lattice k~ with a small changein boron-10 concentration in the Boraflex is shown in Figure l.
4. Question
Will there be any place in the pool under any of the proposed changeswhere it will be possible to place a fuel assembly very close to theoutside of a rack which is filled with fuel assemblies? Such a placemight be the space between the outer periphery of the rack modules andthe walls of the pool. What is the maximum neutron multiplicationfactor that can be obtained in this si.tuation?
~Res ense
Yes. However, the reactivity effect of a fresh fuel assembly locatedoutside the fully loaded spent fuel storage rack has been evaluatedfor all postulated locations, including this area. The maximum per-turbation associated with this event has been calculated to be +0.0186k.
5. Question
Provide the nominal value of the k~ for the PDQ-7 cell model shown inFigure 7 of your submittal.
~Res ense
The calculated k~ of the basic cell at 100 degree F is 0.8775.
6. Question
Provide the maximum value of the k~ that is obtained when the perturbationslisted in Table 3 of your submittal are all assumed to be in the directionthat gives an increased neutron multiplication factor.
~Res ense
The maximum value of k~ for the spent fuel rack under worst mechanicaland thermal conditions with calculational uncertainties is 0.8971.
7. Question
Provide the change in the multiplication factor when axial neutron leakageis assumed.
~Res ense
The change in multiplication factor when axial leakage is assumed is-0.00216k.
ge uestion
NRC procedures require that an on-site test be performed to verify within95 percent confidence limits,'that a sufficient number of neutron absorbingplates (i.e., poison plates) in the installed racks contain the requiredboron content to maintain the k f <0.95. When the poison plates are madean integral part of the racks ani the condition of the poison plates iscontinually monitored by surveillance tests, the NRC finds that a single,initial neutron attenuation test on the racks is sufficient. However, asingle, initial neutron attenuation test will not be sufficient for theproposed racks with the removable poison inserts. Describe how you proposeto periodically perform tests to verify, within 95 percent confidence limits,that there will always be a sufficient number of poison plates which containthe required boron content to maintain the keff ( 0.95 in the proposed storageracks with the removable poison inserts.
~Res onse
The rack design provides one semi-permanent poison assembly per fuelassembly. The poison inserts are not normally removeable and it isanticipated will not be removed from the fuel storage rack for the lifeof the rack, therefore we will satisfy NRC procedures. The poison assem-bly is locked in place by a lock bolt that cannot be removed withoutmechanically deforming the locking element. The lead-in funnel at thetop of the fuel cell location is an integral part of the poison assemblyand thus the presence of the neutron poison plates can be verifiedvisually. The presence of the neutron poison plates will be verifiedvisually prior to the installation of the storage racks in the pool.
Quality Assurance records, during manufacture, will confirm the instal-lation of the Boraflex poison material into every poison assembly. Aneutron attenuation test will be performed at the manufacturer's planton 10 percent of the storage locations after the poison assemblies areinstalled and locked in the racks. A site verification neutron attenu-ation check will be performed on at least 5 storage locations in eachrack module.
Xt should be noted that manufacturing process Quality Assurance pro-cedures and controls provide assurance that the actual BgC content ofthe Boraflex poison material is above minimum calculational levelsestablished by Reactor Physics calculation models for each batch ofB<C and silicone material.

10. Question
What will the maximum integrated neutron and gamma flux be in the Boraflexmaterial over the lifetime of the racks'? What spent fuel assembly powerdensity and burn-up, and what rack life were assumed in calculating thesemaximum integrated fluxes? What is the assumed energy spectrum for thegamma flux'
~Re ense
The maximum integrated neutron and gamma dose expected for the poisonmaterial will be 1.2 x 10 1 Rads. The neutron dose is expected to beno more than 5 x 108 Rads. For the gamma dose calculation, it is assumedthat the poison is subjected to irradiation from the hottest spent fuelassembly (gamma dose design basis peaking factor of 1.25, burnup of33,000 MWD/NT) from 10 days out of the reactor to 18 months. when thenext refueling occurs. It is assumed that the fuel assembly is thenreplaced by the hottest spent fuel assembly discharged at that time.There are 27 such cycles that correspond to a rack life of 40.5 years.Since over 70 percent of the gamma energy is in the 0 to 0.5 NEV group,1 NEV gammas were assumed, making the resulting dose estimate conser-vatively high.
uestion
What will the maximum temperature be in the center of the Boraflex material,assuming the highest neutron and gamma flux and the worst accident conditions?
~Res onse
The maximum temperature in the center of the Boraflex material assumingworst accident conditions is 247 F.
uestion
State the quantity and composition of the gas which will come out of theBoraflex material when it is being irradiated in the spent fuel pool.
~Res onse
Currently a sampl~ of Boraflex material is being exposed in the PhoenixReactor at 2 x 10 R/hr (Gamma). The gas release from a 0.5 inch x O.l inchx 6 inch sample is 15 ml/hr. The composition of the gas being re-leased has been measured as 10% 02, 15% H2, 45% N2, 14% methane, and3% ethane.
uestion
On page 9 of your 1farch 22, 1978 submittal, it is indicated that there isa poison slab which is sealed in a stainless steel casing. Is the Boraflexgoing to be sealed inside of a stainless steel casing?
~Res onse
The Boraflex is canned in a stainless steel casing. The assembly isvented at the top and bottom to prevent gas build up in the casing.
uestion
What will the chemical composition of the Boraflex be after receiving thedesign dose of irradiation?
~Res onse
There will be little or no change in the chemical composition of theBoraflex after receiving the design dose of irradiation.
Question
What is the melting temperature of the Boraflex in the unirradiated-condition?
~Res onse
The Boraflex material does not melt below 1000 F. At 1300 F the Boraflexmaterial begins to char.
uestion
Is the Boraflex going to be bonded to stainless steel? If so, what willhappen to this bond under the design dose of irradiation in conjunctionwith the design number of thermal cycles?
~Res ense
The Boraflex is not bonded to the stainless steel casing.
uestion
What will the physical properties such as the density, the modulus ofrupture, and the compressive strength of the Boraflex be after it receivesthe design dose of irradiation in the spent fuel pool?
~Res onse
Tests performed to date at greater than the design dose indicate that theonly change in properties of the Boraflex after irradiation is an increasein stiffness of the material. This change does not consititute a problemwith the material in regard to its function as a neutron absorber.
uestion
Provide a detailed description of and the documented results of a proto-typical experiment, which includes all significant aspects of the spentfuel pool situation and environment, that shows that these Boraflexplates will not become so brittle from irradiation in the spent fuel poolthat they could be broken up by the insertion and removal of fuel assem-blies or by a safe shutdown earthquake at some time in the design life ofthe spent fuel racks.
~Res ense
A continuous program of irradiation of Boraflex is in progress at thePhoenix Reactor of the University of Michigan. Various tests on Boraflexto date, summarized in the attached "Boraflex 1 Suitability. Report,"No. 1047-1, have demonstrated that the material undergoes no significantphysical or chemical change when exposed to 2 x 10 9 rads gamma irradi-ation. Additional testing of the material is documented in the propri-etary BISCO Procedure 748-10, "Irradiation Studies of Neutron ShieldingMaterials", a copy of which can be supplied on request.
The Boraflex material is fully supported in a double stainless steel canthat is vented at the top and bottom to allow any gas generated to escape.The poison assembly is a complete unit that does not provide the bearingsurface for the spent fuel. The rack structure provides this . Anydistortion of the poison box assembly is contained in the slot within therack that it occupies. A distortion will not affect the fuel cell.
All the structural analyses performed on the poison design racks assumedthe poison material had zero strength and contributed nothing to thestrength of the rack.
19. uestion
If the Boraflex is to be exposed to the pool water, state the maximumpercentage of boron oxide, B203, in the B4C. Since B203 is soluble inwater it will either be necessary to assume that this amount of boronis leached from the Boraflex plates or to experimentally show that thiswill not happen during the life of the racks.
~Res onse
The B203 content in the B4C is less than 0.75.
The Boraflex will be exposed to pool water, however, the silicone rubbermatrix of the Boraflex essentially coats the B4C and B203 particles toprevent the water from contacting it. A 4700 hour test at 240 F inBorated water has shown no leaching to occur. Even if leaching shouldoccur, analysis shows this small decrease in Boron content would havelittle effect on the rack k~ (see figure 1).
20. uestion
Describe the instrumentation and alarms on the spent fuel pool waterlevel and temperature or reference the location in the FSAR wherethis description can be found.
~Res ense
The level alarm system initiates when the water level in the spent fuelpool falls to elevation 338 feet 0 inches. The level alarm annunciatoris located in the control room and on the spent fuel pool panel locatedon elevation 281 feet of the reactor building. The spent fuel pool filtra-tion system has a low pump suction trip alarm and a low flow alarm, both ofwhich would indicate low water level. The pump suction trip alarm and lowflow alarm annunciate on the spent fuel pool panel at elevation 281 feetand the computer prints out an alarm in the control room. In addition,the computer prints out an alarm when the water level falls to elevation338 feet 0 inches.
The temperature alarm system annunciator is located on the fuel poolpanel on elevation 281 feet 0 inches, and a high fuel pool temperaturealarm is printed on the computer. In addition, there is a fuel poolalarm in the control room which can be initiated by high temperatureor anyone of several other parameters. When the fuel pool alarm isannunciated, it can be determined from the computer printout which ofthe parameters has caused the alarm, and action can be taken. Thetemperature alarm system is set to initiate at 113 F.
