SUBJECT:
BALTIMORE C?.S AND ELECTRIC COMPANY'S REVISION TO THE REACTOR VESSEL SURVEILLANCE CAPSULE WITHDRAWAL SCHEDULE FOR CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS 1 AND 2 (TAC NOS. M99127 AND M99128)
Dear Mr. Cruse:
By letter dated June 20,1997, Baltimore Gas and Electric Company (BGE) submitted, for NRC approval, their proposed withdrawal schedule, which was based on the American Society for Testing and Materials (ASTM) E185-70 and ASTM E185-82 and reflected updated fluence information from the surveillance capsules removed in 1992 and 1993 from Calvert Cliffs Units and 2, respectively.
d The NRC staff reviewed the BGE submittal and concluded that the revised surveillance programs for Calvert Cliffs Units 1 and 2 are capable of monitoring the effects of neutron irradiation and the thermal environment on the fracture toughness of ferritic reactor vessel beltline materials for the subject units.
The staff verified that BGE's proposed withdrawal schedules for Calvert Cliffs Units 1 and 2 satisfy the ASTM E185-70 Standard. Since this edition of the standard was current at the time the reactor vessels were purchased, the Calvert Cliffs Units 1 and 2 surveillance capsule withdrawal schedules satisfy the requirements of Appendix H to 10 CFR Part 50. In addition, the staff noted that BGE has implemented the ASTM E185-82 Standard to the maximum extent l.
possible. Therefore, the staff founo that the revised withdrawal schedules are acceptable for l
_ Calvert Cliffs Units 1 arid 2.
