,. v Mr Herman Alderman U S Nuclear Regulatory Commission MaY 15 l>Ye Advisory Committee on Reactor Safeguards Washington, D.C 20555 SUBJECT. ACRS Subcommittee raeetIng on Control poom Design f or the GE p,
ABWR J
Dear Mr. Alderman,
On May 5, I attended an ACRS Subcommittee meeting on the above subject, and this letter presents comments based on Information provided prior to or during the meeting In addition to my comments provided during the meeting, I have only the following concern:
In a previous ACRS subcommittee meeting held to discuss safety analysis topics for the ABWR, both the NRC StafI and I noted what appeared to be potentlally signifcant shortccmings In the ABWR PRA (these are dellnlated in the minutes of the meeting prepared by Medhat El-Zef tawy dated April 28,1992). 't was not clear to me how, t.nen, or if GE was intending to redress these shortcomings. Of concern here is the Intended use o' the PRA to mdke major decislons influencing the Control room design as noted by GE during the May 5 meeting.11' the PRA enhancements Dre nit completed in a timely manner, or If they are not done at all, it is possible that misleading information could be used to make the related control ro?m design decisions. It may be appropriate to monitor the progress of this issue to be certain that the PRA has the appropriate fidellty to allow appropriate control room design decisions.
- a w :a w u, if you have any questions, please call.
