SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos. I & 2; Docket Nos. 50-317 & 50-318 Revision to Reactor Vessel Surveillance Capsule Withdrawal Schedule

REFERENCES:

(a) Letter from Mr. A. W. Dromerick (NRC) to Mr. C. H. Cruse (BGE), dated November 8, 2000, "Safety Evaluation of Request to Revise Reactor Pressure Vessel Surveillance Program Schedule for Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2 (TAC Nos. MA9370 and MA9371)"

(b) Letter from Mr. D. V. Pickett (NRC) to Mr . J. A. Spina, dated April 9, 2008, Revision to Reactor Pressure Vessel Surveillance Capsule Withdrawal Schedule (TAC No . MD8235)

Pursuant to Appendix H of 10 CFR Part 50, Calvert Cliffs Nuclear Power Plant hereby submits for approval a revision to its schedule for withdrawal of reactor vessel material surveillance capsules for Calvert Cliffs Units 1 and 2.

As is the case with the currently approved withdrawal schedule (References a and b), the proposed withdrawal schedule satisfies the requirements of ASTM [American Society for Testing and Materials]

E 185-70, the version that was current at the time the reactor vessels were designed. In addition, to the extent practicable, both the proposed and the currently approved withdrawal schedules comply with ASTM E185-82. The details of the proposed revision are contained in Attachment (1) to this letter.

SCHEDULE Based on the current reactor vessel surveillance capsule withdrawal schedule, the Calvert Cliffs Unit 2 capsule located at the 1040 location is required to be withdrawn during the 2009 refueling outage scheduled to begin about February 24,2009. Therefore, we request that you complete the review of our application by December 31, 2008, to allow us time to prepare for the 2009 outage should you disagree with our proposed withdrawal schedule.

Very tru ly yours ,
