SUBJECT:
NORTH ANNA POWER STATION, UNITS 1 & 2 - SECOND 10-YEAR INTERVAL INSERVICE INSPECTION PROGRAM PLAN REVISED REQUEST FOR RELIEF NO.
NDE-18 (TAC NOS. M95199 AND M95200) l
Dear Mr. O'Hanlon:
The NFC staff, with technical assistance from its contractor, the Idaho National Engineering Laboratory (INEL), has reviewed and evaluated the information provided by Virginia Electric Power Company in its letter dated February 7, 1996, related to the Second 10-Year laterval Inservice Inspection Program Plan Revised Request for Relief No. NDE-18 for the North Anna Power Station, Units 1 and 2.
The staff's Safety Evaluation is contained in. is the INEL Technical Letter Report.
Based on the information submitted, the staff adopts the contractor's conclusions and recommendations presented in the enclosed Technical Letter Report.
In its letter dated February 7, 1996, Virginia Electric and Power Company revised Relief Request NDE-18 that was originally granted conditionally in Safety Evaluation Reports (SERs) issued on August 7, 1995, for Unit 1 and August 8, 1995, for Unit 2.
This relief request was revised to add terminal end piping welds that are associated with the regenerative heat exchangers.
The staff has reviewed the licensee's revised Relief Request NDE-18 and concluded that the Code-required surface examination of the subject regenerative heat exchanger terminal end piping welds would result in a hardship without a compensating increase in quality and safety at the North Anna Nuclear Plant, Units 1 and 2.
In addition, the staff concluded that the licensee's proposed alternative provides reasonable assurance of operational readiness of the regenerative heat exchangers. Therefore, the licensee's l
proposed alternative, to examine the terminal end welds on the lower regenerative heat exchanger sub-vessels, is authorized pursuant to 10 CFR 50.55a(a)(3)(ii).
For the other components of the regenerative heat exchanger contained in the 4
original Request for Relief No. NDE-18, the previous conditional granting of relief pursuant to 10 CFR 50.55a(g)(6)(i) in NRC Safety Evaluations dated August 7,1995, and August 8,1995, remain in effect for the current interval&
