y REQUEST FOR ADDITIONAL INFORMATION BALTIMORE GAS AND ELECTRIC COMPANY CALVERT CLIFFS NUCLEAR POWER' PLANT UNITS 1 AND 2 GENERIC LETTER 88-14 In order to clarify your responses to Generic Letter 88-14, please provide the following information:

1. The actual Units 1 and 2 instrument air system particulate-per-cubic-foot results. including specifications and a discussion of why no adverse effects are posed, to the operability of any specific safety-related components, by any high (i.e., out-of-vendor-specification) particulate concentrations.

2.- The schedule for completion of tests on the Unit I air-operated i

safety-related components. Your May 25, 1989 letter stated that these tests would be performed during a maintenance outage scheduled for the fall of 1989. As Unit 1 is now in an extended outage, with restart planned for no earlier than November 1989, and as the Unit I maintenance outage has been deferred until the spring of 1990, the NRC staff does not have an accurate understanding of your intended schedule for completing Unit I testing.
