Appendix A NOTICE OF VIOLATION Based on the results of the NRC inspection conducted on February 12, 1980, it appears that certain of your activities were not conducted in full compliance with the conditions of your NRC Construction Permit No. CPPR-129 as indicated below:
Failure to Follow Test Procedure Criterion V of 10 CFR 50, Appendix B requires that activities affecting quality shall be accomplished in accordance with instructions, procedures or drawings.
Brown & Root repair procedure RCB-1, "She.'.1 Lif t 15 Investigation and Repair Criteria," No. 2C801CQ002-C, paragraph 8.2 states in part, "To make a water pressure test, water from the grout pump through the skid mounted pressure gage and control valve was connected to :he lowest hole at a bracket Maximum gage pressure was limited to 30 to 35 psi to protect the liner."
Contrary to the above:
On February 7, 1980, the Resident Reactor Inspector (RRI) determined, through interviewing the licensee's lead civil engineer on site, that approximately 60 psi of water pressure was accidentally applied to the void areas behind the RCB-2 liner plate and a 10 x 14 feet section of the. liner bulged approximately 4-5 inches toward the center of the containment.
Additionally, the RRI found that no safety relief or " pop off" valve was in the test line to protect the liner against excessive pressure.
This is an infraction.
