Schedule for System 80+" Resiew j

Reference:
Letter, D. M. Crutchfield (NRC) to A. E Scherer (C-E), dated July 22,1991
Dear Mr. Crutchfield:
This : letter responds to the reference letter, which requested that Combustion Engineering, Inc. (C-E) provide information on the basis for the System 80+ review schedule.-
The schedules discussed by C-E ir. May 1991 are no longer considered realistic in light
- of developments since that time. Our currently projected schedule, as compared to that shown in SECY-91-161, is listed below. Our projected dates are consistent with those which we dienswd during the NRC ALWR conference in Washington, DC on
- November 4 and 5. %ey are also consistent with the schedules shown in the first annual update to_the NPOC Strategic Plan for Building New Nuclear Power Plants.

r Mr. Dennis M. Crutchfield LD-91-063 December 2,1991 Page 2 You also requested that we identify "the list of assumptions" used to develop our schedules. We believe the following assumptions are pertinent:
A meaningful Draft Safety Evaluatica Report (DSER) can be issued by the Staff five months after respor.ses to Rats (nrsus seven months in SECY-91 161). As an evolutionary ALWR, System 80+ does not represent a fundament;d departure from proven technology and is consistent with current regulatory criteria.
he DSER can be issued without completion of Staff review of the " Inspections, Tests, Analyses and Acceptance Criteria" required by 10 CFR Part 52. Those areas where Design Acceptance Criteria will form the basis for the DSER must be identified and resolved prior to its issuance.
The Final Safety Evaluation Report can be issued ten months after issuance of the DSER (versus 13 months in SECY-91-161). This is, of course, dependent upon a relatively complete DSER with a manageable number of open items.
De second Design Certification Rulemaking for the industiy (i.e., the ABWR would be the first) can be conducted in 12 months (versus 18 months in SECY 91-161).
We are unable to meaningfully provide "the uncertainty range (error bars)" associated with these schedules.
We trust that this information has been responsive to your request. We will continue to meet with the NRC staff to resolve any open issues and to complete the resiew of the System 80+ design. We continue to believe that a mutual commitment to identification and resolution of specific issues is the key to achieving these schedules.
If you have any questions, please contact me or Mr. Stan Ritterbusch of my staff at (203) 285-5206.
Very truly yours, COMBUSTION ENGINEERING, INC.
