Dear Dr. Reytblatt:
This letter responds to your letter of February 20, 1987, and its attachments.
The Chairman has referred your technical concerns to the Commission's staff to determine if you have raised new or different issues not previously considered in response to your earlier requests. The staff has completed its review of the subject letter and concludes that you have not raised any new or different issues and that the issues identified in your letter of February 20, 1987, and b
its attachments, have been considered in response to your earlier requests.
One item in your February 20, 1987 letter and its attachments, was described as a " newly discovered" description of a Zion Leak Rate Computer program. You identified this description, Attachment R to PT-PC-101, as a page from a typical Commonwealth Edison computer program description.
It states that, should the number of temperature sensors in a containment subvolume become equal to zero (due to sensor failures), the temperature of the next higher number subvolume will be used for the temperature of that subvolume. The NRC has previously reviewed the issue of inoperable temperature sensors and determined that if there are no functional temperature sensors in a subvolume, then the average temperature of an adjoining subvolume may be used. The Zion plant uses subvolumes that are numbered such that consecutive subvolumes are adjacent to each other. Therefore, this issue is not new and has been previously considered by the staff.
