Dear Jim:

Enclosed is a monthly report for May for the ContainmentIntegrity Program. Also enclosed is a copy of a memo from J.Jung to S. Hatch that documents a short effort by Joe Jung toestimate the ultimate capacity of several containments. Finally,we thought you might be interested in the types of problems wehave with the general purpose finite element codes. I'menclosing a copy of a listing of ABAQUS errors and a recent listof MARC bugs from MARC Program Update. You can see that thesecodes require a very sophisticated user and very careful checkingof re=ults.

Sincercly,

| MONTHLY REPORT

l CONTAINMENT INTEGRITY PROGRAM.

May 1983i

| Data reduction for the test of model SC-1 is continuing. Ast noted in the quick-look report (included in the April report),j data from the LVDT's is questionable because of a defective; bracket. Therefore, displacement measurements from other sources; are particularly important. Efforts to transform the CDS data

that was hand recorded during the experiment have yet to be,

successful. As a back-up, photographs taken remotely during thetest have been forwarded to Sandia's photometrics and OpticalDevelopment Division. Displacement measurements from the

,

i perspective of the camera should be available in mid-June.

j preparations for the testing of model SC-2 were accelerated; during May. Wiring connectors that caused minor difficultyI during the testing of model SC-1 have been replaced. Most strain

gages were installed on the model. The model was shipped toj Mechanical Measurements for precise location of the gages and the! CDS targets. The test of model SC-2 is now tentatively scheduled

for July 14, 1983.

Because of the time required to try to resolve the difficultiesi

with the data reduction of model SC-1, the updated analyses ofmodel SC-2 have not been finished. Complete analyticalpredictions are still expected before the model is tested.i

! Difficulties with the fabrication of model SC-3 have beeni encountered. Trial welds of the penetrations into a " practice"

model that has ring stiffeners have been unsuccessful. A welding; fixture has been ordered. * practice with the new fixtures will be; done on model SC-1.a

! Fabrication of the large steel model is progressing on schedule.A request for quotations for a contract for site preparations isnearing completion.

A meeting was held in Boston on May 3, 1983 to kick-off theconcrete modeling contract with Stone and Webster EngineeringCorporation (SNEC). Sandia was represented by R. T. Reese and T.E. Blejwas. Present from SHEC were M. B. Stetson, J. W. Steereand S. Martinez. R. N. White of Cornell University, a consultantto SHEC, was also present. The objectives and scope of the

study were reviewed. Preliminary work by SWEC, that summarizesthe structural features of reinforced concrete containments, was.

presented.

A short presentation on the containment program was given by TomBlejwas to the Containment Capability Subgroup of the ASCEMaterials and Structural Design Committee of the NuclearStructures and Materials Committee.

Presentations on the containment integrity program were given byW. A. von Riesemann to the Subcommittee on Shells and Ligaments;and Task Group on Gasket Testing of the Design Division of thePressure Vessel Research Committee at their spring meeting in NewYork City, May 23-25, 1983.

The status of funding for May in attached as Table I. The costsare estimates only and may not match the invoice sent to the NRCby Sandia's accounting department. A plot of spending for FY83is attached as Figure 1.

TO ALL LEASE CUSTOMERS

Enclosed is a tape with a new release of ABAQUS. The version is called4-4-53. The significant errors that have been corrected are:

1. Temperatures were not printed for dependent nodes in MPCrelationships in heat analysis.

2. Rotary mass terms were missing for shell elements, causingsingularity problems in dynamic analysis.

3. Several problems with Post Output were corrected.4. The F3D foundation option was not working.5. The foundation options for 2-D solids were not working.6. Layer parameter of the MATERIAL keyword card did not work.7. Intermittent sizing problems with hybrid beams causing the analysis

to terminate.8. The heat interface elements (DINTERx) did not work.9. The interface elements caused overwrite problems in some cases.

10. Restart within a VISCO step did not work.11. Temperature input via the file option did not work for a VISCO

procedure.12. Riks method in combination with temperature loading did not work.13. Temperature loadings on ELB0W elements were not interpolated

correctly.14. The J-integral capability did not work with the hybrid solid

elements.15. The minimum time and maximum time values given for the *VISCO

option were ignored.16. Applying distributed loads to the axisymmetric shell elements in a

large displacement analysis could cause a sudden abort.17. Element B34 could not be used for large displacement prob 1 cms.18. Boundary conditions could not be changed in a heat analysis.19. The hybrid beam elements could not be used with * BEAM GENERAL

SECTION.20. The hybrid 8-node solid did not work.21. Element SPHEX2B did not work.22. * FIELD could not be used for solid elements.23. Plotting of the 27 node brick elements did not work.

IamalsoenclosingonesetofUpdates(Rev.4.4(a))foryourUser'smanual. Additional copies can be ordered from us for 35 per set.

Please have the new version installed as soon as possible and return thetape to us.
