April 7,1987 U. S. Nuclear Regulatory Commission Washington, DC 20555 ATTENTION: Document Control Desk SUB3ECT: Calvert Cliffs Nuclear Power Plant Unit No. 2; Docket No. 50-318 Changes to Request for Amendment Eighth Cycle License Application

REFERENCES:

(a) Letter from Mr. 3. A. Tiernan (BG&E) to NRC, dated February 6,1987, Request for Amendment to Operating License DPR-69, Eighth Cycle License Application Gentlemen:

We request that the Calvert Cliffs Unit No. 2 Cycle 8 License Application (Reference (a)) be altered to reflect an actual end of Cycle 7 burnup of 13,580 MWD /MTU vice the ,

assumed 13,300 MWD /MTU cycle burnup referenced currently by the reload application I for Unit 2 Cycle 8.

Page 1-1 of the attachment to Reference (a) addresses the assumed Cycle 7 maximum burnup of 13,300 MWD /MTU. When the safety analyses were performed to support the Cycle 8 reload, current Unit 2 operating trends indicated that the Cycle 7 burnup would be conservatively bounded by a maximum cycle burnup of 13,300 MWD /MTU. When the Request for Amendment for the Eighth License Application (Reference (a)) was in preparation, it was realized that since Unit No. 2 was operating at a higher than anticipated capacity factor, the possibility existed that the 13,300 MWD /MTU burnup limit could be exceeded. In fact, reference to this possibility was made on page 2-1 of Reference (a).

The supporting safety analyses for Unit 2 Cycle 7 were reevaluated to a maximum cycle burnup of 13,700 MWD /MTU and the effects on the Unit 2 Cycle 8 safety analysis were

! reanalyzed with the resultant conclusion that the 13,300 MWD /MTU limit could be l exceeded up to final burnup of 13,700 MWD /MTU without impacting the analyses' results. l

l It has been determined that there is no significant impact on any of the results reported In the Unit 2 Cycle 8 reload submittal and there is no affect on the Determination of

! Significant Hazards presented (Reference (a)). There are some minor changes in some of  ;

I the reported numbers in the submittal. Enclosed are nine pages that reflect these changes. These pages replace those pages from the original reload submittal (Reference (a)) and a vertical bar in the page margin identifies what has been changed from the original.

Very truly yours,
