SUBJECT:
ARKANSAS NUCLEAR ONE, UNIT NO.1 - ISSUANCE OF AMENDMENT RE: ALTERNATE REPAIR CRITERIA FOR FLAWED TUBES THAT HAVE EXPERIENCED OUTER DIAMETER INTERGRANULAR ATTACK (TAC NO. MA4761)
Dear Mr. Hutchinson:
l The Commission has issued the enclosed Amendment No. 202 to Facility Operating License No. DPR-51 for the Arkansas Nuclear One, Unit No.1. The amendment consists of changes to the Technical Specifications (TSs) in response to your application dated May 14,1999
- (1CAN059901), as supplemented by letters dated June 17,1999 (1CAN069905), September 7, 1999 (1CAN099901), September 15,' 1999 (1CAN099902), September 17,1999 (1CAN099905), and September 24,1999 (1CAN099906).
The amendment revises the TS requirements affecting the surveillance criteria for that portion of the once-through steam generator tubes regarded as a primary-to-secondary pressure boundary located within the upper tubesheet and impacted by a specific degradation mechanism, namely, outside diameter intergranular attack.
In preparation for refueling outage 1R15, you submitted six applications requesting action on the part of the staff, four TS amendments and two relief requests. In no case did you allow for the customary 6-month review period between your submittal date and the date for which you requested action by the st.*f. As a result, four of your six applicatione were approved by the Commission immediatr'y proceding or during refueling outage 1R15. Completion of these items required special prioritization and handling in order to accommodate your outago schedule. Furthermore, two additional items were identified during refueling outage 1R15 where you requested action on the part of the staff. The first item was a TS amendment for a steam generator tube repair criteria that was submitted as an exigent request. This amendment request was later withdrawn, at your discretion, after a considerable expenditure of
. resources on the part of the staff.. The second item was a relief request to authorize an attemative repair for a flaw identified in the casing for the loop B low pressure injection (LPI) pump. This flaw was identified in conjunction with a system pressure test conducted during the refueling outage.
The staff recognizes that the need for a relief request to repair the flaw in the LPI pump could not have been anticipated. However, the staff has concluded that the scheduling issues associated with the other seven items were within your control. The staff has identified that resource limitations may have played a significant factor in the deficiencies described above. In addition, the staff has identified technical weaknesses associated with some of your applications which required either follow-up submittals or protracted discussions to resolve.
