20555 Gentlemen:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 10 CFR 50.44 On December 6,1991 GPU Nuclear made a presentation to the NRC Staff describing the Oyster Creek Nitrogen Inerting System (NIS). A very brief summary of the meeting was issued by the NRC Staff on December 11, 1991. The purpose of this letter is to highlight some of the important portions of our presentation and to confirm our intentions for a follow-up meeting.
In the December 6, 1991 meeting we restated that the Combustible Gas Control System for Oyster Creek was the inerted containment. 'Ihis position was set forth in our May 31, 1991 letter and has been our position throughout. We further stated that the NIS may be used as a backup to that primary system under conditions beyond the licensing basis and as such was not designed to meet the requirements of 10 CFR 50.44.
As pointed out in our presentation we do see the NIS as important to supporting the operation of the facility. We also presented to your staff two modifications currently in progress which will l
further enhance the NIS. We have concluded that these modifications, the Hardened Vent modification and the Station Blackout modification will improve the overall reliability of the NIS.
As agreed to at the conclusion of our presentation, we are preparing for a mid-February meeting at the Oyster Creek site at which we will further discuss capabilities of the NIS and present our assessment as to whether any further or additional actions (either procedural or hardware) are appropriate.
If no action is deemed appropriate we will provide you with our bases for making that determination.

We believe this is appropriate in that the intent of the meeting is to address the NIS system reliability rather than how it meets the design requirements of 10 CFR 50.44.
If there are any questions on this subject please feel free to con *act Mr. S. Tiwari of my staff at (201) 316-7433.
Sincerely, 7
