Dear Mr. Taylor-I
SUBJECT:
DRAFT UPDATE OF STANDARD REVIEW
- PLAN, CHAPTER 7,
i
" INSTRUMENTATION AND CONTROLS" During the 435th meeting of the Advisory Committee on Reactor Safeguards, October 9-12, 1996, we reviewed portions of-the draft H
update of Standard Review Plan (SRP), Chapter 7,
" Instrumentation and Controls. " We heard presentations by and held discussions with
. representatives of the NRC staff and its contractor, the Lawrence Livermore National Laboratory (LLNL),
regarding -proposed' SRP l
sections and Branch Technical Positions (BTPs) related to digital instrumentation and control (I&C) systems.
In addition, our-Subcommittee on Instrumentation and Control Systems and Computers met with the NRC staff and LLNL on October 8, 1996, to discuss this l
matter. We had previously met with the staff and LLNL in March and l
May 1996 to discuss draft SRP sections,
- BTPs, and associated regulatory guides, and provided comments in a letter dated June 6, 1996.
We also had the benefit of the documents referenced.
We have no objection to the staff's proposal for issuing the draft update of SRP Chapter 7 and associated BTPs for public comment.
However, in the June 6, 1996 letter, we identified issues regarding L
the level of detail provided in the regulatory guides, the balance in the guidance between the review of the design process and the l
assessment of the product, the linkage between Chapter 7 and other i
SRP chapters, and graded approaches based on importance to safety.
In a letter dated June 21, 1996, you responded to our letter of
(
June 6, 1996, stating that the staff will continue its discussions l
with the ACRS on these issues.
We plan to discuss these matters l
with the staff during our future meetings.
l Sincerely,
/s/
