Docket No.
50-445/80-08 50-446/80-08 Appendix A NOTICE OF VIOLATION Based on the results of an NRC appraisal of your action during the period of December 13, 1979 to present, it appears that certain of your activities were not conducted in full compliance with the conditions of your NRC Construc-tion Permit No. 127 as indicated below:
Failure to Report a Significant Construction Deficiencv 10 CFR 50.55(e) (1) states:
"If the permit is for construction of a nuclear power plant, the holder of the permit shall notify the Commission of each deficiency found in design and construction, which, were it to have remained uncorrected, could have affected adversely the safety of operations of the nuclear power plant at any time throughout the expected lifetime of the plant, and which represents:
(iii) A significant deficiency in construction of or significant damage to a structure, system, or component which require extensive evaluation, extensive redesign, or extensive repair to meet criteria and bases stated in safety analysis report or construction permit or to otherwise establish the adequacy of the structure, system, or component to perform its intended safety function.
10 CFR 50.55(e) (3) further states:
"The holder of a construction permit shall also submit a written report on a reportable deficiency within thirty (30) days to the appropriate NRC Regional Office.
"If sufficient information is not available within 30 days, an interim report containing all available information shall be filed, together with a statement as to when a complete report will be filed."
Contrary to the above:
On December 13, 1979, the Permit Holder notified the NRC Resident Reactor Inspector (RRI) that attempts to remove concrete " honeycomb" in certain interior walls of the Unit Two Containment Building had developed into an unexpectedly difficult deficiency.
The Permit Holder also informed the RRI that a consultant would be employed to perform a sonic (microseismic) investigation of the walls involved.
On January 17, 1980, the Permit Holder notified the RRI that the sonic investigation was complete and that the Architect / Engineer was evaluating the results along with visual' examinations, 060 M g96
Beginning in December 1979, the Permit Holder has performed extensive engineer-ing evaluations either for the purpose of establishing the methods of repair or for evaluating the adequacy of the structure without repair, yet the Permit Holder has failed to furnish the NRC Regional Office with either an interim or final written report'on this matter within the time period set forth in.10 CFR 50.55(e).
