Office of Advanced Reactor Programs Office of Nuclear Energy U. S. Department of Energy Washington, DC 20545
Dear Mr. Gavigan:
Members of the NRC staff and its contractors (BNL and SAIC) met with members of the DOE staff and its contractor (GE) for a briefing by GE on their plans
.j and rationale for a proposed rulemaking. The rulemaking would add an l
Appendix 5 to the NRC regulations contained in 10CFR50. As proposed, the l
appendix would define a procedure leading to certification of an advanced I
reactor based on a final design and prototypical testing.
Attached are the agenda and list..of attendees Enclosures 1 and 2, respectively. The Sumnary Record of the meeting is contained in Enclosure 3.
Per agreement et the meeting, we will continue discussions on this subject at a second meeting in early October 198,7.

i ENCLOSURE 3 First Meeting Proposed 10 CFR 50, App. S Summary Record 4 August 1987 l.
BACKGROUND The Department of Energy (DOE) is funding the conceptual development of three advanced reactors for commercial application. Two of the concepts are based on small modular liquid metal reactors (LMR).
The third is based on a modular high temperature gas cooled reactor (MHTGR). The designer of one of the LMR's, the General Electric PRISM reactor, has proposed that a rulemaking be initiated to provide regulations for a certification procedure for licensing. The procedure would lead to essentially a one-step licensing process for this standardized design.
i 2.
OBJECTIVES The primary objectives of the meeting were to:
i.
introduce concepts associated with the proposed appendix, ii. develop an approach to and rationale for rulemaking, iii. establish a schedule for completion of evaluation.
3.
OPTIONS While the approach proposed is to use a rulemaking to implement a new regulation, various alternatives were explored. GE considers the existing 10 CFR 50 appendices, notably M, N, and 0, to be either inconsistent with the current economic situation or not intended for this type of reactor.
Modifications to the existing regulations are considered to be too cumbersome. The process proposed would draw heavily on the methods used by the Federal Aviation Agency (FAA) in certifying equipment types, production and use, or airworthiness. Major differences exist, however, in that the FAA regulations are far more prescriptive than those in
~
use by the NRC or proposed at this meeting.
GE noted that use of Appendix 0 has been tested only through the final design approval stage. The experience in these cases was, however, based upon proven designs with demonstrated performance.
In the case of the proposed advanced concepts, existing operational data are not available.
There is also an expectation on GE's part that the ABWR certification process may establish precedents that restrict, rather than open up, application of Appendix 0.
Thus, GE noted that there would be greater assurance of clear regulations for certification of the first of a kind equipment being developed, if a new Appendix S were established specific to l
these concepts.
l 4.
CONTENTS OF PROPOSED APPENDIX S The draft of the proposed appendix was noted to be similar to the
+
existing Appendix 0.
The draft, however, notes that the intent is for I
final designs only. As proposed by GE, the basis for certification would I
l i
l l
l
be an acceptable final design and an approved prototypical safety test program. The resultant test report would be submitted for NRC review and acceptance.
5.
GE PROPOSED SCHEDULE FOR CONTINUED DISCUSSIONS The schedule proposed is as follows:
i Initial meeting August 1987 Review Example Certification Basis Document October 1987 Review Example Certification Basis Test Plan October 1987 Concerns and Plans November 1987 i
NRC Response January 1988 l
DOE /GE Submit Proposed Rule June 1988 Rulemaking Begins June 1988 l
f 6.
DISCUSSION Dr. Morris (NRC) noted that construction and testing of a reactor to its design margins will take considerable discussion and review within DOE as well as the NRC. GE responded that with the PRISM inherent safety design i
the beyond design basis events do not lead to core melt as with LOFT.
The design of the test plan is relying heavily on the experience gained 1
with SEFOR.
l Mr. Rowden (GE Legal Consultant) noted that the procedures and the bases for conducting the review are not mutually exclusive. We should be able to proceed simultaneously with developing the path for the review while conducting the review of the plant. The process being proposed is open and generic. The goal at this time is an indication of continuation of j
discussions.
Mr. Dorian (NRC) informed the group that OGC is preparing proposed rules to implement as much of the Comission's proposed licensing reform i
legislation as is permissible under the Commission's existiny statutory authority. The suggested appendix may work better as a part of the proposed rules rather than as a separetc appendix. This will be pursued further and the discussions will continue, i
