Dear Mr. Stewart:
- June 19, 1991
SUBJECT:
- SURRY UNIT 1 - INSTALLATION OF INSTRUMENTATION FOR ASME SECTION XI TESTING AT SURRY POWER STATION UNIT 1 (TAC NO. 79259)
On August 31, 1990, we issued a Safety Evaluation (SE) for the Surry, Units 1 and 2 ASME Inservice Testing Program for Pumps and Valves.
Relief from required pump testing described in item 3 of the Techni~al Evaluation Report (TER) accompanying the SE was granted provided that instrumentation required to perform the testing was installed during the next refueling outage.
Your letter of November 28, 1990, stated that although installation of the pump instrumentation began during the October 1990 refueling outage, some of
,the required instrumentation was not installed.
You encountered a number of unanticipated problems, which included unavailability of instruments and supporting material, interfaces with nearby structures and gage accuracy.
- The letter also stated that most instruments which were not installed during the Unit 1 outage will be installed during the operating cycle, and instruments in systems which cannot be rendered inoperable during plant operations will be installed during the next refueling outage scheduled for April 1992.
You requested NRC approval to delay full Code compliance as necessary to support plant operation until the instrumentation can be installed.
You have also committed to a satisfactory interim inservice pump testing program.
A summary of the installation status of the pump instrumentation required to perform the testing identified in item 3 of the TER is provided in Table 1 (enclosed).
You specifically stated that the instrumentation not installed for the emergency diesel generator fuel oil pump, emergency service water pump and the inlet pressure instrument for the boric acid transfer pump will be installed in the first quarter of 1991, during Unit 1 operation.
You stated that the flow instrumentation required for the Unit 1 charging pump and the boiic acid transfer pump will be installed during the next Unit 1 refueling outage.
Your proposed alternative interim inservice testing program, as described in of the November 28, 1990 submittal, has been reviewed.
We have determined that the interim testing program will provide an acceptable level of quality and safety.
Imposition of~immediate compliance would result in a long outage which would cause you an undue hardship without a compensating 9106260040. 910619 PDR ADOCK 05000280 :.
