Dear Mr. Cruse:

On August 17,1995, the NRC issued Generic Letter (GL) 95-07, " Pressure Locking and Thermal Binding of Safety-Related Power-Operated Gate Valves," to request that licensees take actions to ensure those safety-related power-operated gate valves that are susceptible to pressure locking or thermal binding are capable of performing their safety functions.

In a letter dated February 13,1996, Baltimore Gas and Electric Company submitted its 180-day response to GL 95-07 for Calvert Cliffs Nuclear Power Plant, Unit Nos.1 and 2. The l Nuclear Regulatory Commission (NRC) staff reviewed the licensee's submittal and requested I additional information in a letter dated June 18,1996. In a letter dated July 25,1996, the l licensee provided the additionalinformation. The NRC staff performed two inspections to I review specific aspects of information summarized in the licensee's responses to GL 95-07.

These inspections are documented in NRC Inspection Reports 50-317,318/97-02 and 50-317, 318/98-09. In a letter dated December 2,1998, the licensee supplemented its 180-day response to GL 95-07.

The NRC staff has reviewed the licensee's submittals and finds that the licensee has adequately addressed the actions requested in GL 95-07, as discussed in the enclosed safety evaluation. This completes our efforts on TAC Nos. M93444 and M93445.

Sincerely,
