Hoyle, Acting-Secretary
SUBJECT:
STAFF REQUIREMENTS - BRIEFING ON DECOUPLING SITING' REQUIREMENTS FROM FUTURE DESIGNS AND UPDATE OF SOURCE TERM MATTERS (SECY-90-341),
2:00 P.M.,
MONDAY, OCTOBER 15, 1990, COMMISSIONERS' CONFERENCE ROOM, ONE WHITE FLINT NORTH, ROCKVILLE, MARYLAND (OPEN-. TO PUBLIC ATTENDANCE)
The-Commission was briefed by the NRC staff on source term update l
and decoupling siting from design.
A number of questions were raised by the Commission concerning the methodology to accomplish the goal of updating the source i
term and decoupling it from siting requirements..The staff o
-should provide the Commission a response to the following questions.
1.
How long woul'd it take to incorporate Regulatory. Guide 4.7 into.the regulations?
Why should the portions of Part 100 which influence design remain in place'until the final step,
-as proposed in the staff's plan?
2.
The staff's proposa'. states that.the second revision to Part 100 and the revision to Part 50.would-be accomplished prior to the completion of review of passive designs.
How will this schedule allow designers to provide for the.new requirements of these two rulemakings in their designs?

(SECY Suspense:

The Commission believes.'that this proposed program is an important step in establishing a stable regulatory process for plant design and siting and emphasizes the need to coordinate NEPA considerations with plant design considerations in such a

manner that the scope of the analysis of severe accident l
mitigation design alternatives (SAMDAs) is clearly defined and factored into the regulatory process.
This activity should be closely coordinated with OGC and the process (not necessarily the final rule) should be in place in time for evolutionary plant design FDAs.
The Commission requested that !t be informed of the staff's and OGC's options for integrating the 03MDA decision into the regulatory process.
(EDO/OGC)
(SECY Suspense:
2/28/91)'
Tre staff should brief the Commission periodically as it develops the definition of releases into containment, specifically to 9
adv.'se the Commission of the potential accident scenarios used as j
a technical basis for this definition.
Further, the staff should pericaically brief the Commission as it develops a policy on the use of the updated TID-14844 by existing plants.
(EDO)
(SECY Suspense:
3/29/91)
Because decoupling siting requirements from future plant design requirements and updating source term methodologies would require significar.c revisions to 10 CFR Part 50, Commissioner Remick requetted the staff to be mindful that changes to Part 50 should be viewed from the perspective of whether such changes would affect non-reactor and non-power reactor requirements " hidden" in Part 50.
Further, he requested that staff assess the viability of simultaneously separating non-reactor and non-power reactor licensing activities from Part 50, including the resources
'i required to accomplish the separation.
If this effort would significantly impact the schedule for updating Parts-50 and 100, then he requests staff to advise the Commission of the viability of a. parallel effort such that a thorough-analysis of-Part 50 need only be conducted once.
He' believes that the process applied by the CHWRA to the requirements within Part 60 could be a useful model for this activity.

(SECY Suspense:
2/28/91)
Additional staff requirements may result from the Commission's consideration of SECY-90-341 and will be included in the SRM from that paper, cc:
