Dear Mr. Beedle:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REGARDING ONE-TIME SURVEILLANCE INTERVAL EXTENSIONS FOR THE JAMES A. FITZPATRICK NUCLEAR POWER PLANT (TAC F0. M86766)
By letter dated June 16, 1993, the Power luthority of the State of New York (PASNY) requested changes to the Tect.nical Soecifications that would provide a one-time extension of the current in',e.vals for certain safety / relief valve, snubber, and excess flow check valve surveillances. The staff has completed a preliminary review of the PASNY sebmittal and identified the need for additional information in order to complete our review. We, therefore, request that PASNY provide a response to the questions enclosed.
In order to support timely resolution of this matter, we request a response within 30 days of receipt of this letter.
This requirement affects one responder.t nd, therefore, is not subject to Office of Management and Budget review under P.L.96-511.

f, ENCLOSURE RE0 VEST FOR ADDITIONAL INFORMATION ONE-TIME SURVEILLANCE EXTENSIONS FOR FITZPATRICK SAFETY / RELIEF VALVES (SRVsl 1.
The submittal stated that the plant Target / Rock 2-stage SRVs have experienced significant setpoint drift. The staff has also received similar information regarding significant setpoint drift at other plants.
Have there been circumstances similar to those at FitzPatrick where Target / Rock 2-stage SRVs were not tested for extended periods of time, and how were those SRV setpoints affected for the extended periods?
2.
The staff has had recent discussions with Boiling Water Reactor Owners Group (BWROG) representatives regarding the resolution of the Target / Rock 2-stage setpoint drift issue. These discussions indicate that the pilot disc-to-seat sticking would be lessened significantly by reducing the large concentrations of oxygen in the pilot valve area with a catalyst coating on the pilot valve surface areas. A second measure would be to install additional pressure-sensing power actuation equipment to assure that the valves open at the correct setpoints.
Has PASNY endorsed these recommendations, and what is PASNY's schedule for implementation of specific measures to improve setpoint performance?
SNUBBERS 1.
Please describe the test and inspection results from the last snubber surveillances (i.e., number and types of failures).
2.
During the proposed extension period will the service life for certain snubbers expire?
l 3.
Are there any indications of age-related snubber degradation (especially for hydraulic snubbers)?
Please provide a compilation of test dates and results for the excess flow check valves.
2.
Identify the manufacturer and model number of these valves and provide any available industry performance data on these valves, such as the number of failures reported in the NPRDS.
3.
Please discuss PASNY's basis for concluding that the excess flow check valves were not expected to degrade while the plant was shutdown for the extended outage that ended in January 1993.
1
. 4.
Provide a list of the excess flow check valves that were tested during the extended outage that ended in January 1993.
5.
If the list of excess flow check valves affected by the submittal is different from the list of valves in Inservice Testing Program Relief Request V-28, please provide a list of the affected valves.
6.
Please discuss the length of time involved in testing all excess flow check valves, the possible impact of attempting to test all valves during the three week maintenance outage in September 1993, and the efforts that would be involved if a percentage of the valves were required to be tested (i.e., 30%, 50%, or 70%).
