Dear Mr. Grier:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 I E Bulletin No. 80-17 The subject bulletin required certain testing pertinent to the Scram Discharge Volume (SDV), vent / drain valves and associated piping.
The purpose of this letter is to forward findings which constitute partial response as required by paragraph 8.
Specifically, this letter documents the results of tests performed on July 8-9 to satisfy action item 1 of the subject bulletin. A description of item 1 and the associated response are as follows:
ITEM 1.
Within 3 days from date of this bulletin, perform surveillance tests to verify that there is no significant amount of water in the Scram Discharge Volume (SDV) and associated piping and that the SDV vent valves are operable and vent system is free of obstructions.
RESPONSE
1.
The SDV discharge header piping was surveyed by performing ultrasonic testing at fourteen check points.
Point selection was based upon an engineerirg review of the piping system for points most likely to contain water. This testing revealed no water was present in the piping.
2.
Verification of SDV vent valve operability and lack of system obstructions was performed by isolating the discharge header piping at the related vent and drain valves, pressurizing this 8008060 0\\7_-
. n.
Mr. Boyce H. Gricr, Dir:ctor July 11, 1980 piping to 100 PSIG and manually opening one of the two vent valves. This process was repeated for the second vent valve.
j During each opening event it was observed that the SDV depress-urized rapidly through the open vent valve.
Subsequently, the above valves were returned to normal operating status and cycled to verify valve operability. All vent piping and valves were observed to be free of obstructions and fully operable.
Additional responses to remaining items shall follow pending performance of associated tests.
