REQUEST FOR ADDITIONAL INFORMATION CALVERT CLIFFS NUCLEAR POWER PLANT. UNIT NOS.1 & 2 INTEGRATED PLANT ASSESSMENT ON GENERIC SAFETY ISSUES DOCKET NOS,50-317 AND 50-318 s

1. Describe the BGE process and criteria for determining which unresolved generic safety issues (GSis) listed in NUREG-0933, "A Prioritization of Generic Safety issues," should be reviewed to identify any concerns that may be related to the effects of aging or time-
limited aging analyses for systems, structures or components within the scope of license 4

renewal.

2. Discuss whether BGE specifically evaluated GSI-23, " Reactor Coolant Pump Seal Failures," and GSI-173.A, " Spent Fuel Storage Pool: Operating Facilities," as relating to the license renewal aging management review or time. limited aging evaluation, as described in an NRC staff letter to the Nuclear Energy Institute (NEI), dated January 29, 1998. If yes, identify where these GSis are evaluated in the application or describe the BGE evaluation results. If not, provide the justification that such an evaluation is not l Warrantea.
3. In a letter dated June 2,1998, the staff concluded that license renewal applicants can address GSI-168, " Environmental Qualification of Electrical Equipment," by providing a technical rationale demonstrating that the current licensing basis for EQ pursuant to 10 CFR 50.49 will be maintained in the period of extended operation. The NRC staff has not completed guidance on the information necessary to demonstrate adequate aging management for the EQ time limited aging analyses (TLAAs). Until that matter is

. resolved, please provide the EQ Master List of electrical equipment and indicate which of I the TLAA categories in 10 CFR 54.21(c)(1) apply to each of the electrical equipment l j

groups. In addition, summarize the procedures that are used to maintain compliance with the requirements of 10 CFR 50.49, and justify that those procedures will adequately manage the EQ analyses for the period of extended operation.
