Subject:

LaSalle County Station Unit 1 Request for An Emergency Change to NPF-11 Appendix A Technical Specifications Regarding Reactor Fecdwater Inboard Check Valves Type C Test NRC Docket No. 50-373

Dear Mr. Denton:

The purpose of this letter is to request the following emergency change in Technical Specifications for LaSalle County Station Unit 1.

CHANGE REQUEST NPF-ll/83-05 Exempt the reactor fecdwater inboard check valves from Type C test requirements until startup following the first refueling outage.

This proposed change is addressed in Attachment A and has rcccived onsite and offsite review and approval. Unit 1 startup is expected around November 30, 1983; but may occur as carly as November 27, 1983. Therefore we feel that this change falls within the Emergency Change Category.

A condition for approval o# an cmcrgency amendment requires the licensce to appropriately demonstrate why this emergency situation occurred and wny it could not avoid this situation c.g. that the licenscc did not " create" the emergency situation in order to take advantage of the cmergency provision of 10CFR 50.91.

Although we determined on November 3, 1983 that the feedwater check valves in question failed their Type C test we had undertaken several corrective actions in the following weeks, as delinated in Attachment A, to the point where we believe the scal designed on material for these valves will be essentially identical to those successfully used and tested at other sites for several years. With these corrective sctions we believe the valve will pass future Appendix J tests.

Nevertheless Regional NRC inspectors of ficially notified us on November 18, 1983 that they could not allow startup on the basis of the history of the past failures and that an exemption to provisions of Appendix J would be a startup condition. Accordingly we are submitting this amendment request. ff 90
