Appendix A NOTICE OF VIOLATION Cincinnati Gas and Electric Docket No. 50-358 Company Based on the results of an NRC investigation conducted on January 22-24, 1980, it appears that certain of your activities were not conducted in full compliance with NRC requirements as noted below. This item is an infraction.
10 CFR 50, Appendix B, Action XI requires "a test program shall be established to assure that all testing required to demonstrate that structures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate applicable design documents".
CG&E FSAR Section 3.8.1.7.2.1, Sargent & Lundy Procedure NFSD 4210-PC-3 and start-up procedure PRP-05 requires the containment structural integ-rity test to be performed in accordance with ASME Section III, Division 2, Article CC-6000, 1977 Edition. The structural integrity test is to demonstrate that the containment will perform satisfactorily in service.
The above procedures had been completely approved by engineering and quality assurance as meeting applicable design documents.
Contrary to the above, the containment structural integrity test does not comply with the requirements, as follows:
1.
ASME,Section III, Division 2 CC-6238.1 requires the pressure gauges have a range of 1-1/2 times test pressure but not more than 4 times test pressure.
CG&E test procedure does not require this.
2.
ASME,Section III, Division 2 CC-6241 requires acceptance limits to be provided for each pressurization increment for all devices in order to permit determination that the test may proceed to the next increment of increased pressure. CG&E test procedure only provides acceptance limits for final test pressure of 52 psi but does not provide limits for each pressure increment, i.e., 13, 26, 39 psi.
3.
FSAR Section 3.8.1.7.2.1 requires temperature to be maintained above 70*F during the test.
CG&E test procedure does not include this temperature limit.
4.
FSAR Section 3.8.1.7.2.1 requires crack patterns for all cracks larger than 0.1 inch be mapped; however, Code Article CC-6233 and l
l 8 0 0 4 210G7
Appendix A t r
Regulatory Guide 1.18 requires crack patterns for cracks larger than 0.01 inches be mapped.
5.
FSAR Section 3.8.1.7.2.1 indicates that elastic behavior of the containment has been demonstrated if after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> depressurization the deflection recovery is 85% or more. S&L specification NFSD 4210-PC-3, Section 6.4.1.3 indicates that only 80% recovery is re-quired to demonstrate recovery.
6.
ASME,Section III, Division 2 CC-6233 requires the pattern of cracks that exceed 0.01 inch in width before, during and after the test to be mapped. CG&E procedure requires crack mapping only at 0 and 52 psi. The procedure should require mapping at 0, 13, 26, 39 and 52 psi.
