Dear Mr. O'Reilly:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 Status Report for IE Bulletins No. 75-04 and No.75-04A
Reference:
My Letters to you of May 27, June 30, August 1, and August 28, 1975 This reports the status of incomplete activities that were initiated in response to -IE Bulletins No. 75-04 and No.75-04A.
Since the August 28, 1975, status report on the fire' detection and suppression system, the following activities have occurred or have been initiated.
1.
We are undergoing a determination of a type of detector which will respond to the products of combustion from a polyvinyl chloride (PVC) fire since there have been reports of the inability of various detectors to indicate the presence of a PVC fire. This investigation has caused delay in the finalization of the system specifications.
2.
The Modification Proposal for the installation of the fire protection system has been given conceptual approval by both the Plant Operations Review Committee and the General Office Review Board.
Final approval is pending specific installation details.

Mr. James P. O'Reilly
- Page,II October 1, 1975 In response to IE Bulletin 75-04A, Question G, and to concerms identified by the Nucicar Regulatory Commission in their investigation of the Browns Ferry incident, Jersey Central will be conducting a test of aqueous film forming foam (A.F.F.F.).
The A.F.F.F. will be tested, using a 2-1/2-gallon portabic fire extinguisher,.to determine its ability to quench an electrical cabic tray fire.
If the tests so indicate, A.F.F.'F.
will be' used as the final fire suppression medium. The results of this testing will be available shortly.
The engineering evaluation of available penetration sealing -
materials, mentioned in my. August 1, 1975 letter, identified Foamed-In-Place Silicon Rubber as the optimal scalant.
It is anticipated that during the next thirty-day period an engineering survey of the necessary arca penetration seals will be conducted. This survey will facilitate
- the installation of' the scaling material.
The status of the Shutdown and Emergency Procedures review is unchanged, i
Ver truly you'rs, Donald A. Ross, Manager Generating Stations-Nucicar s
