(a) License No. DPR-28 (Docket No. 50-271)
(b) Letter, D. G. Eisenhut to Licensee, dated November 13, 1980
Subject:
Response to Requirements of NUREG-0619
Dear Sir:
The subject report was issued in final form via Reference (b) which required Vermont Yankee to commit to certain plant modifications within specified timeframes. We have reviewed the report and have concluded that the requested commit =ents cannot be made at this time. The bases for the NUREG-0619 requirements are drawn from generic studies which must, by their nature, encompass all plants. We must point out that the experience at Vert:ent Yankee relative to the issues of NUREG-0619 has been significantly better than the average BWR.
For example, Vermont Yankee replaced its original loose fit spargers with interference fit spargers in 1976. Prior to replacing the original spargers, we experienced less cracking and much shallower cracking than predicted by generic data. Following installation of the interference fit spargers, inspections were performed after one year and three years of operation. These inspections revealed thet Vermont Yankee has experienced no cracking with the new spargers.
~
We feel that modifications of the magnitude required by NUREG-0619 c:ust be clearly understood and must be evaluated carefully on a plant specific basis, and only after it is concluded on a plant specific basis that implementation of the modifications will provide some benefit in terms of
- aperation or increased plant safety should the changes be made.
In order for this issure to be resolved as soon as possible, we propose that a meeting between Vermant Yankee and NRC personnel be held as soon as practicable.
