C. 20555 1 % ,, # September 8, 1987 Docket No. 50-286 Power Authority of the State of New York ATTN: Mr. John C. Brons, Executive Vice President Nuclear Generation 123 Main Street White Plains, New York 10601 1 1 Gentlemen: SUBJECT: SAFETY SYSTEM OUTAGE MODIFICATION INSPECTION (DESIGN) 50-286/87-013 This letter conveys the results and conclusions of the design portion of the I Safety System Outage Modification Inspection (SSOMI) of the Indian Point Unit 3 i power station conducted by the NRC's Office of Nuclear Reactor Regulation. The l inspection team was composed of NRC personnel and consultants. The inspection l took place at the Indian Point Unit 3 station and your offices in White Plains, l New York. It was conducted April 22-23, May 11-15, May 26-29, and July 12-14, 1987. The purpose of the design portion of the SSOMI was to examine, on a sampling basis, the detailed design and engineering which was required to support modifications implemented during the outage. At the conclusion of other portions of the inspection, the NRC will provide a report summarizing these efforts. The design inspection team noted significant areas of weakness in the design and design verification process associated with the replacement of the service water pumps. The team also found two instances where PASNY was using relaxed design criteria from that specified in their FSAR and NRC Bulletin responses without obtaining prior staff approval and examples where the FSAR and techni- cal specification bases had not been updated to reflect changes made during a previous outage. Weaknesses were also noted in the areas of design change control, the performance of safety evaluations in accordance with 10 CFR 50.59, control of FSAR information and the ability to retrieve design basis infonna- tion, as noted during the team's review of the 25 kVA inverter installation. Based on the findings of this inspection, PASNY management should take action to ensure that (I) adequate controls are in place to maintain plant configura- tion; (2) the plant licensing basis is updated to reflect design changes as required by 10 CFR SC.71(e); and (3) the engineering staff and design agents are aware of the plant's licensing bases. It is important that during any modification the licensee examine carefully the original design and licensing bases to assess all the design considerations that are affected by the change. _.

September 8, 1987 of New York- During the inspection, a newly initiated program to reestablish the design - basis of the plant was explained to the inspection team. This effort indicates your awarenessiof this weakness and that some positive steps to achieve con- figuration' control. are being taken. Clearly, more work is needed in.this area. Because of the team's significant findings related to your service water pump replacement design, you decided to defer installation of the new replacement pumps.- These findings indicate serious shortcomings. in your vendor interface - <and design. verification programs. Accordingly, I request that you respond to , the findings of this report within 60 days including a description of.the . actions you'have taken or plan to take to strengthen your control' of design interface and design verification activities. . Also, please include-in your response a description of your self-initiated program to reestablish the plant's-design basis. In contrast to these weaknesses, the team observed that many things had been - done. correctly and that you have taken an active role-in identifying problems and correcting them in a timely manner. The proposed replacement of the service water pumps,' for example, was ' initiated to improve system reliability as a result of a poor maintenance history for the original pumps. Also, the flow model testing and improvements made:to the service water system intake bays.should further enhance pump performance and system reliability. During the inspection, the team found that Indian Point 3 does not meet.its FSAR commitment in the area of moderate energy line break. The FSAR states that the plant can mitigate the consequences of a LOCA with a simultaneous guillotine failure of a moderate energy line. However, the team found one _ . example where this comitment was not met. This- FSAR comitment is more conservative than the guidelines set forth in Standard Review Plan 3.6.1 for moderate energy line cracks, and we call this to your attention so that it can be resolved as promptly as possible.
Some of the items identified by the team may be potential enforcement ' findings. Any enforcement actions will be identified by Region I. In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosure will be placed in the NRC Public Document Room. Should you have any questions concerning this portion of the inspection, please contact me or Mr. E. V. Imbro (301-492-9664) of this office. Sincerely, I _ even aNa, b .
