• Denotes persons attending exit meeting of May 14, 198 . Surveillance Testing Procedures The inspector reviewed current revisions of several surveillance test procedures to determine whether or not: required review and approvals had been received; prerequisites and acceptance criteria for the test were specified, and; provisions for restoring systems or components to operation following testing were included: The following surveillance test . procedures were reviewed:

• ST 5099.01 " Miscellaneous Instrument Shift Check"

• ST 5075.01 " Service Water Monthly System Test"

• ST 5011.01 " Boric Acid Flow Path Heat Tracing Weekly Test"

• ST 5063.11 " Containment Air Cooling System Monthly Test"

• ST 5099.02 " Miscellaneous Instrument Daily Checks"

• ST 5074.01 "CCW System Monthly Surveillance Test" ST 5016.02 " Fire Protection System - Electric Pump Weekly" ST 5011.05 ", Boron Injection Flowpath Quarterly Valve Test"

• These procedures were also reviewed to determine whether or not test methodology ensured conformance with applicable Technical Specification surveillance requirement No items of noncompliance were identifie Surveillance Tests The inspector reviewed surveillance test results to determine whether or not: tests were performed at the required periodicity; completed test results received required reviews and approvals and; where acceptance criterion were not met, appropriate correc-tive action was initiated and completed in a timely manner. The

Inservice Testing of Pumps and Valves Pumps Inservice test procedures and results were reviewed for the follow-ing pumps included in the licensee's inservice test programs:

Auxiliary feedwater pump 1-1 Auxiliary feedwater pump 1-2 Component cooling water pump 1-1 Component cooling water pump 1-2 Containment cooling water pump 1-3 Containment spray pump 1-1 Containment spray pump 1-2 Decay heat pump 1-1 Decay heat pump 1-2 Diesel fire pump 1-1 Electric fire pump 1-1 High pressure injection pump 1-1 Service water pump 1-1 Service water pump 1-2 Service water pump 1-3

'

The inspector evaluated inservice test procedures against the requirements of 10 CFR 50.55A and the licensee's approved in-service test program. The inspector reviewed inservice test results to determine whether or not: inservice tests were per-j formed at the required periodicity and; data was evaluated, and-

corrective action taken as required. No items of noncompliance j were identifie Valves ( In the course of reviewing pump test procedures and results, the L inspector also reviewed inservice test data for valve tests in-cluded as part of pump test procedures. The valves and their i respective testing requirement (s) satisfied by these procedures are listed below.

The 1974 edition and addenda through summer 1975 of the ASME boiler and pressure vessel code,Section XI paragraph IWV 3520 (b)(2) requires that for swing or tilting disk type valves, if the exercise test is made by use of fluid flow through the valve, the pressure differential for equivalent flow shall be no greater than that observed during the preoperational tes The inspector determined that the licensee uses flow as the exercise test parameter for these types of valves. As is the case with almost all operating facilities, the licensee's preopera-tionalests did not include measurement of differential pressures across individual valves. The applicability of this requirement will be addressed on a generic basis by the NRC Office of Nuclear Reactor Regulatio No items of noncompliance were identifie . Instrument Calibration The inspector reviewed: calibration data for selected components in Safety Features Actuation System (SFAS) and Steam and Feedwater Rupture Control System (SFRCS) instrument channels; calibration data for cer-tain portable test instruments used to satisfy Technical Specification surveillance requirements; several completed channel functional tests for Reactor Protection System (RPS) instrument channels and, several completed instrument channel calibrations for the Borated Water Storage Tank Level input to SFAS. The review was conducted to determine whether or not channel calibrations and channel functional tests were performed at the frequencies specified in the Technical Specifications and in accordance with procedures which had received required reviews and

approvals. Also, the review was made to determine whether or not speci-fled calibration tolerances were consistent with required tolerances, and that specified calibration tolerances were met in the "as-left" condition. Calibration data was reviewed for the following instruments:

SFAS Instrumentation PT 2000 PT 2001 PT 2002 PT 2003 PT RC2A3 PT RC2A4 PT RC2B3 PT RC2B4 UT 1525A LT 1525B LT 1525C LT 1525D SFRCS Instrumentation PS 3689A PS 3689B PS 3687 PS 3687B PDS 2685C PDS 2685D
