u t. i', 2 8 i?R Docket Nos. 50-317 50-318 Mr. Robert E. Denton Vice President - Nuclear Energy Baltimore Gas and Electric Company Calvert Cliffs Nuclear Power Plant 1650 Calvert Cliffs Parkway Lusby, Maryland 20657 - 4702
Dear Mr. Denton:
SUBJECT:
CALVERT CLIFFS UNITS 1 AND 2 SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE INSPECTION This letter confirms the dates of March 7-11 and March 21-25, 1994, for a service water system operational performance inspection (SWSOPI) at Calvert Cliffs Units 1 and 2. A pre-inspection visit by the team leader and some of the team members is also scheduled during the week of February 22,1994, to gather information requested in the enclosure to this letter.
The primary objectives of this inspection will be to assess the design, operation, maintenance, surveillance, and testing aspects of the service water system at Calvert Cliffs and to determine whether this system is capable of performing its intended safety functions during plant operating and accident conditions. The team will also evaluate the implementation of the quality assurance and corrective action programs as related to the SWS and your planned and completed actions in response to Generic 12tter 89-13, " Service Water System Problems Affecting Safety-Related Equipment." As noted in our letter of August 12 93, we will make every effort to minimize the impact of this inspection by using the redts of your service water system self-assessment to the extent practical.
We request that you make available the information listed in Enclosure I during the pre-inspection visit scheduled for the week of February 22,1994. While the inspection will involve both Units 1 and 2, you need only provide the requested inspection materials for Unit 1. If significant differences exist between Units 1 and 2 in any of the functional areas, l
you should provide the necessary information to clarify the differences.
