CLARiflCATION OF PREVIOUS REACTOR VESSEL SURVEILLANCE PROGRAM ACTIONS AND W11HDRAWAL SCHEDULE CHANGE FOR THE UNIT 2 REACTOR VESSEL MATERIAL SPECIMENS, CALVERT Cliffs NUCLEAR POWER PLANT UNIT NO. 1 (TAC NO. M85113) AND UNIT NO. 2 (TAC NO. M84440)

By letter dated August 28, 1992, Baltimore Gas and Electric Company (BG&E) provided clarification of previous reactor vessel surveillance program actions for both units and requested Commission approval for a change to the withdrawal schedule for the reactor vessel material surveillance capsules which are located in the Unit 2 reactor vessel. The requested change to the withdrawal schedule was submitted pursuant to Appendix H of 10 CFR Part 50.

The NRC staff has reviewed the clarifications provided and determined that they have not diminished the reactor vessel material surveillance program and are acceptable. The NRC staff further concludes that BG&E has provided the necessary technical justification required by Section ll.B.3 of Appendix H to 10 CFR Part 50 to support the proposed changes to the withdrawal schedules for reactor vessel material surveillar..e capsules in the Unit 2 reactor. The second withdrawal interval capsule to be withdrawn is at the 97 degree 120011 mi i 9301130272 921223 7 )V\ g ADOCK 0500 4
