Dear Mr. Taylor:
SUBJECT:
DRAFT UPDA*E OF STANDARD REVIEW
- PLAN, CHAPTER 7,
"IM3TRUMENTATION AND CONTROLS" l'
During the 435th meeting of the Advisory Committee on Reactor Safeguards, October 9-12, 1996, we reviewed portions of the draft update of Standard Review Plan (SRP), Chapter 7,
" Instrumentation c.nd 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 sections and Branch Technical Positions (BTPs) related to digital instrumentation and control- (IEC) systems.
In addition, our Subcommittee on Ir.et rumentation and Control. Systems and Computers met with the NRC sLaff and LLNL on October 8, 1996, to discuss this matter.
We had previously met with the staff and LLNL in March and j
May 1996 to discuss draft SRP sections, BTPs, and associated regulatory guidoc, 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 the level of detail provided in the regulatory guides, the balance in the guidance between the review of the design process and the-assessment of the product, the linkage between Chapter 7 and other SRP chapters, and graded approaches based on importance to safety.
In a letter dated June 21, 1996, you responded to our letter of i
l
'une 6, 1996, stating that the staff will continue its d Scussions I
with the ACRS on these issues.
We plan to discuss theca matters with the staff during our future meetings.
l Sincerely,
{
