SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS.1 & 2, l lNTEGRATED PLANT ASSESSMENT REPORTS FOR THE SALTWATER COOLING SYSTEM (TAC NOS. MA1020, MA1021, AND M99219)

Dear Mr. Cruse:

By letter dated December 17,1997, Baltimore Gas and Electric Company (BGE) submitted for  ;

review the Saltwater Cooling System (5.16) integrated plant assessment technical report as attached to the " Request for Review and Approval of System and Commodity Reports for License Renewal." BGE requested that the Nuclear Regulatory Commission (NRC) staff review >

the Saltwater Cooling System (5.16) integrated plant assessment technical report te determine if the report meets the requirements of 10 CFR 54.21(a)," Contents of application-technical information," and the demonstration required by 10 CFR 54.29(a)(1), " Standards for issuance of a renewed license," to support an application for license renewalif BGE applied in the future.

By letter dated April 8,1998, BGE formally submitted its license renewal application.

The NRC staff has reviewed the Saltwater Cooling System (5.16) integrated plant assessment technical report against the requirements of 10 CFR 54.21(a)(1) and 10 CFR 54.21(a)(3). By letter dated April 4,1996, the staff approved BGE's methodology for meeting the requirements of 10 CFR 54.21(a)(2). Based on a review of the information submitted, the staff has identified in the enclosure, areas where additional information related to scoping is needed to complete its review. Should the staff have additionalinformation needs related to aging management they will be forwarded in future correspondence.

Plaase provide a schedule by letter or telephonically for the submittal of your responses within 30 days of receipt of this letter. Additionally, the staff would be willing to meet with BGE prior to submittal of the responses to provide clanfications of the staff's requests for additional information.

1 REQUEST FOR ADDITIONAL INFORMATION j CALVERT CLIFFS NUCLEAR POWER PLANT UNIT NOS.1 & 2 l SALTWATER SYSTEM INTEGRATED PLANT ASSESSMENTECTION 5.16 DOCK?T NOS. 50-317 AND 50 318 Section 5.16.1 - Sconina

1. According to Figure 5.16-1 and Subsection 5.16.1.1, essentially all of the saltwater l system is within the scope of license renewal. The saltwater supply to the circulating I water system (CWS) pump seals and the CWS discharge conduits are identified as nc,t within the scope of license renewal. Since Figure 5.16-1 does not show any valves, it is not clear where the interface location is between the portions of the system that are within and outside the scope of license renewal, and how the interfacing locations were ,

chosen. Please identify more clearly the interfaces between the portions of the  !

saltwater system that are within and outside the scope of license renewal, and if  !

possible, provide a revised drawing that shows the interface locations more clearly. '

Please provide the basis for the %terfaces that define the portions of the saltwater system that are within and outside the scope of license renewal, and if possible, a more general discussion of the process used for identifying interfaces to assist tne NRC staff with its review of other sections of the license renewal application (LRA) where scoping interfaces are discussed.

2. Figure 5.16-1 shows an emergency discharge line coming off the pump discharge header (in lieu of the system discharge header). The NRC staff believes, based on the information provided, that the emergency discharge line coming off the pump discharge l would be a safety-related attemative to the system's normal discharge path to the CWS )

discharge conduits. Please describe the function of this line. j 1

3. Figure 5.16-1 does not show the suction piping to the saltwater pumps. Please identify i whether the suction pioing is included within the scope of license renewal. If so, provide 1 a cross reference to where the suction piping is addressed in the LRA. Also, identify  ;

any strainers and/or screens associated with this system anti discuss whether these components are within the scope of license renewal. !f so, provide a cross reference to where these components are addressed in the LRA. If either of these components are not within the scope of license renewal provide the basis for their exclusion.
