TEST CRITIQUE Preparations for the Containment Structural Integrity Test (SIT) were completed Friday March 14, 1986 and pressurization commenced l at 0735 March 15, 1986. Operation of the pressurization system
. was practically trouble-free. One compressor failed to restart
] following -the 26 psig plateau inspection. - Starter problem was corrected and the compressor was back on line within 30 minutes.
A second compressor failed during pressurization to 39 psig but was returned to service within one hour. No other system problems were encountered.
1 Containment exterior crack mapping was accomplished with no significant problems. Only one surface area was required to be crack mapped in addition to the original five specified by UE&C.
This was in the O' elevation electrical penetration area between i
penetration H57 and H46. At the.39 psig and 50 psig plateaus, STD personnel inspected other areas identified as potential abnor-malities per NCR 59/5518A. All areas were accepted-as-is.
Con tainmen t interior measurements were completed with 63 DCDT's.
l Of these, four experienced programatic problems which were resolved and corrected during initial pressurization. One l instrument was found, af ter SIT, to have polarity reversed on installation, and two others were found to be reversed in loca-tion. These seven items did not effect final results. During t
post SIT inspections, one DCDT was found to be stuck, one bracket i
had detached from the liner and another DCDT was damaged .when the i
1

TEST CRITIQUE 1 bracket fell from position. Data from these three instruments was used only up to the point where they were suspected to have failed. Test exceptions 1-10 note these items. Interpretation of data and comparison with predicted results will be per Brewer Engineering Laboratories final report. Integrated Leak Rate Tes ting (ILRT) was performed per 1-PT(I)-37.1 during the depressurization phase of SIT. This test commenced at the 39 psig depressurization interval and took approximately 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br />.
Final O psig measurements and inspections were completed at 1030 March 21, 1986. Recovery criteria was met after approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />.
Calibration data for DCDTs'(pre and post test) are included as attachment 9 5 to PT-36. Also in this attachment are the calibration data for Brewer data logger and associated instru-ments. SIT pressure was read at two 0-150 psig gages (FLS-357, FLS- 10 34 ) . Calibration data is available from M&TE.
The only information included in this test package which is not l
attached to PT-36 is the final report from Brewer Engineering Labora tories .
As Test Director for the Structural Integrity Test, I have reviewed preliminary data and discussed these results with UE&C Engineering. I consider this test to have been satisfactorily completed and recommend completion acceptance of .1-PT(I)-36.

l 1.2 The test is intended to demonstrate the following:
1.2.1 As the containment is pressurized, the deflections of the containment's structural elements and the cracks of its exterior concrete surface are within
- predicted limits.
1.2.2 After depressurization, acceptable recovery is achieved.
1.2 3 The yielding of reinforcement does not develop as determined from analysis of crack width or deflec-tion data.
