} Director, send a letter to the Commission expressing the ACRS

endorsement of Mr. Fujimoto.

f j~ 3) MRETING WITH ACRS EYECUTIVE DIRECTOR AND NEW COMMISSIONERS Dr. Larkins, ACRS Executive Director, met with Commissioner i

Diaz on October 2. The role of the ACRS in the regulatory process, the technical backgrcund of members, and current l Committee activities were discussed. Dr. Larkins emphasized i the fact that the ACRS is a valuable resource for the

! Commission and has been asked by the Commission, as well as by l individual Commissioners, to address a number of key technical

. and regulatory issues. Additionally, the Commissioner was

invited to meet with the ACRS to provide his views on priority j issues coming before the Commission or any issue he might want i to discuss. Dr. Larkins will meet with Commissioner j McGaffigan on October 10.

I

4. INTERNATIONAL MEETINGS i

}' A. Dr. Yasumasa Togo, Chairman, Nuclear Safety Commission,

Japan, sent a . f ax (p. 13) proposing that the next

Quadripartite Meeting be held in October 1997.

I l B. The German RSK Committee sent a fax (p. 14) to suggest

that the proposed meeting with ACRS on advanced reactor l research be postponed until spring 1997. Ms. Summers

! replied by fax (p. 15) to suggest that this topic either j be added to the agenda for the Quadripartite Meeting

(which at that time was tentatively scheduled for the

( same time frame),-or that a separate meeting be arranged

during one of the ACRS meetings in 1997. In light of the j postponement of the Quadripartite Meeting, it is more

likely that a separate meeting will be scheduled.

e

! C. Ms. Summers is co-chairing a Panel Session at the Pacific

Basin Nuclear Conference in Kobe, Japan, on October 20-l 25, 1996. During her trip to Japan, she also plans to j discuss the Quadripartite Meeting dates and agenda with Dr. Togo. A previous letter to Dr. Togo (p.16) proposed

, several topics for discussion. These topics should be

reviewed by the Committee so tnat Ms. Summers can take an l updated list to Japan.

i i RECOMMENDATIONS l

! A. The Subcommittee recommends that ACRS Members review

their schedules for October 1997 and indicate, during the y

i . ..

3 l

October 17-19, 1996 meeting in Boston, any dates during i that month that would not be suitable for them to attend a Quadripartite Meeting in Japan.

i B. The Subcommittee recommends that, after the Committee determines the Full Committee meeting dates for CY 1997, a fax be sent to the German RSK Committee suggesting that

they choose a meeting date that would coincide with one of the scheduled ACRS meetings.

C. The Subcommittee recommends that the ACRS Members review the topics listed in the attached letter to Dr. Togo and 4

make any additions or revisions during the October 1996

, meeting.

l

5) RETREAT Dr. Seale has prepared a proposed schedule and outline for

discussion during the October 17-19, 1996 meeting in Boston (pp. 17-20). Members are requested to provide their comments

! during this meeting.

l RECOMMENDATION l

! The Subcommittee recommends that Members provide Dr. Seale

, with comm2nts on the proposed schedule and outline during the j October 1996 meeting.

6) NRC'S REBASELINING/ STRATEGIC PLANNING ACTIVITIES l ACRS Members were sent a package containing the Direction Setting Issue (DSI) Papers for their review and comment.

l Comments were requested by October 4. So far, comments have

been provided by Dr. Powers, Dr. Fontana, and Mr. Barton.

Subcommittee Chairmen should discuss their preference for Committee comments, individual comments, or no comments. Any proposed Committee comments would have to be drafted this month for issuance next month. The ACNW will be provided copies of ACRS comments and vice versa.

RECOMMENDATION The Subcommittee recommends that all Members read the DSI papers and make recommendations to the Committee for deciding: l e Should the committee comment on any of these DSIs, and, if so, which DSIs?

e If the committee decides not to comment on certain DSIs, do individual Members want to send their personal vieus on the DSIs?

, l 1

1 i

The Members should provide their comments and recommendations l so that the Committee can make its decision on Saturday,

3. October 12, 1996.

Dear Dr. IARKINS,

Thank you very much for your fax message dated 1996.9.25.

We reconsidered the schedule of the next Quadripartite Meeting. After all, I propose again that the next meeting would be held in, at the earliest, in October of 1997. And my staff have started preparations for it, but the progress is vety slow for several reasons. For the sake of our planning the next Quadripartite Meeting, if possible, I would like to listen your hope. But unfortunately, I and our staff don't have planning to attend the Paci5c Basin Nuclear Conference. So that we won't hold ,

the meeting in Kobe. If it is not too inconvenient, I would like to meet Mr. Summer at our office during the week of October 28-November 1.

In the meantime we would ven much appreciate hearing from you again in this regard.

Sincerely yours, i

Dear Dr. Candell:

Thank you for your fax of September 23rd. Dr.Larkins has suggested that perhaps the subject of advanced reactor research could be included in the Quadripartite Meeting also being proposed for Spring 1997. We have had no reply from Dr. Togo regarding the proposed dates or agenda for that meeting. If you prefer a separate meeting, we  ;

will try to arrange a suitable date during one of the ACRS meetings next year. When '

the 1997 meeting dates have been set, I could forward them to you for consideration.

Please let me ks6ow which solution is preferable.

Dear Dr. Togo:

We have just received a letter from Mr. Cogn6, of the French Groupe Permanent Charg6 des R6acteurs Nucl6aires, agreeing to a Quadripartite Meeting in 1997. The Advisory Committee on Reactor Safeguards (ACRS) agrees that such a meeting should be held in Japan in the fall of 1997.

The ACRS proposes the following items for discussion at the 1997 meeting:

)

e Risk-informed regulation,  ;

e Fire modeling, '

e Individual Plant Examination process, e Role of expert judgment, o Steam explosions. I e Recent operating experience, particularly issues associated I with steam generators.

1 As Japan is the host country, we suggest that you propose the  !

dates and a draft agenda for this meeting as soon as possible.  !

Please let us know if we can be of assistance in this effort.

I have asked the Technical Secretary of the ACRS, Ms. Roxanne Summers, to be the point of contact for the purpose of planning this meeting. She can be reached by telephone at 301-415-7371 or i by fax at 301-415-5589. We look forward to hearing from you in i the near future.

j o EPRI feels non-safety grade equipment ought not be used in the context of'd esign basis!

! analysis of Sssion product removal.

i i I l o EPRI feels it should be permissible to bring equipment on site to handle i!  !

j recovery from a design basis accident.

jj i  ;

i i i j

i I would suspect that the Chairman will want to understand the basis for the contrary Isws by ACRS on these topics. I would expect that we would be questioned on these subjects a our j forthcoming meeung with the Commission.

Pelley Issues rhataintag To The APG00 Design

Dear Chairman Jackson:

1-The purpose of this letter is to endorse Wesdnghouse positions dataued is reference 1, submitted a the NRC in response to NRC senE recasunendettms to the &==3='a==s '

AP600 poucy issues (reference 2). This j endorsement of the use positions is provided on behalf of the j j Advanced Light Water Reactor (ALWR) Utiuty Steerism Comunittee (U9Cl,iwhich '

l is the body that directs the utility community's Snancia , and s=rhale=1 support for the national effort to develop and certify advanced light water reactor desip'w.  ; j l '

l i

l References 1 and 2 disagree on two policy issues, " Prevention and Mitigation of l I

Severe Accidents" and " Post 72 Hour Actions", for which near-term dedsinns by t

the Ceaunissioners are sought by reference 2.

l l

The USC's prindpal concern is with the followmg portiets of the staff l

AdditioneBy, the sinf reqdest for a pokey decision is premature.1he stag i nanot i

Weedaghouse. In addition, very recent discussion betwesa Sandia and l W is aspected to lead to sonne re n ===aw of the tandia A&put tAthe

NRC. is a good basis for anticipating that these continuing interactkimis j wlB land to a conclusion that the AP900 passive safety-related features for Basion 4

product renneval are clearly adequate to meet the stringent regulatory mquirements.

1 l The tJSC is also concerned with the fouowing staff recomunendation on "P z+72 Hour Actions". .

(Thk condanent is included as a ==himad

i i The USC is also concerned that the staff's recommendation on " Font 72 Hour j Adined' would severse NRC'r prior a:eeptanes of the relevant dasse of p ALWR 1N1118y MA- rts Docuswr.t, with which the AP600 cosaph ,these chuses were the result of a thorough assessment by the industry, as to the /dng-l tena allablBey of the various options.

{ inconsistent with the reference 1 characterization of the extremely low ii j prohnbuity (less than one in a billion per year) that the relevant AM00 features

would not prove entiral)s adequate.
