Dear Chairman Carr:

SUBJECT:

SECY-90-353, L7'ENSING REVIEW BASIS DOCUMENT FOR THE COMBUSTION ENG1d1ERING, INC. SYSTEM 80+ EVOLUTIONARY F

LIGHT WATER REAC'I3R During the 367th meetino of the Advisory Committee on Reactor Safeguards, November 8-10, 1990, we reviewed the staff's SECY 353, " Licensing Review Basis Document for the Combustion Engineer-ing, Inc. System 80+ Evolutionary Licht Water Reactor," dated October 12, 1990. Our Subcommittee on Advanced Pressurized Water Reactors also cor.sidered this matter during a subcommittee meeting on November 1, 1990. During this review, we had the benefit of discussions with representatives of the NRC staf f and of Asea Brown Boveri Combustion Engineering. We also had the benefit of the documents referenced.

The staff has recommended that the Licensing Review Basis (LRB)

- ef fort for the Combustion Engineering (CE) System 80+ design, which is well advanced, be continued to completion. There does not appear to be any substantive disagreement between the staff and CE on issues addressed in the LRB document.

The only approved LRB document was proposed by the General Electric Compa (GE) as a way of obtaining early agreemercc with the staf f on ma or process and technical issues for the review of its advanced boiling water reactor design certification application.

It was approved by the Director of NRR in a letter to Mr. R.

Artigas, GE, on August 7, 1987. This letter contains the qualifi-cation that the LRB represented the approach in "certain key areas" that GE was committed to follow " . . . until final Commission positions and staff requirements are de#ined and implemented." At that time, neither 10 CFR Part 52 nor Commission-approved staff

[ positions relating to the certification of advanced light water reactors such as SECY-90 -016 (referenced) were available. We note

, that 10 CFR Part 52 does not discuss the use of LRB documents as a part of the final design approval or certification process.

These regulatory requirements and others under development have preempted the need for and diminished the usefulness of an LPS document for the CE System 80+ design. We recommend that no further effort be devoted to the proposed LRB document for the CE System 80+ design.

'the Honorable Kenneth M. Carr 2 -November 14, 1990 Additional comments by ACRS members Ivan Catton, Paul G. Shevmon, and J. Ernest Wilkins, Jr., are presented below.

Sincerely, dk 2 Carivle Michelson Chai; man Additional Comments by A2RS Members Ivan Catton Paul G. Shewmon, and J. Ernest Wilkins. Jr.

We understand that this LRB document can be completed and issued with-relatively little additional effort. If so, we would prefer to see an orderly disposition of this LRB document in accordance-with the staf f recommendation in SECY-90-362 (referenced). We would agree with:our colleagues that the CE System 80+ LRB effort be terminated now if the Commission, the staff, and'the ACRS need to invest any significant additional effort.
