recommendations.
RECONCILIATION OF ACRS COMMENTS AND RECOMMENDATIONS s
The Executive Director for Operations' (EDO's) responses to previous ACRS reports were discussed as follows:
j e
EDO letter, dated September 3,
1992, responding to the ACRS report dated August 12, 1992, concerning ITAAC for GE ABWR.
Based on additional discussions during the meeting with Mr.
- Russell, the Committee found the EDO's response to the Committee's comment about ensuring "that components and systems in the plant can be expected to have reliabilities which are consistent with those assumed in the PRA" to be acceptable.
However, with regard to the Committee's interest in reviewing the so-called generic ITAAC, the Planning and Procedures Subcommittee will recommend which ACRS subcommittee should handle this assignment.
A recommendation of the subcommittee to handle this matter will be made to the Committee during the November 1992 ACRS meeting.
EDO letter, dated October 5,
1992, responding to the ACRS report dated August 14, 1992, concerning GSI 106, Piping and Use of Highly Combustible Gases.
The EDO letter was responsive to the Committee's comments.
The ACRS staff was asked to follow-up on the status of the staff's review of the INEL Report that was written as part of this effort e
EDO letter, dated October 1,
1992, responding to the ACRS report dated August 27, 1992, concerning fatigue _ evaluation procedures.
The EDO letter was responsive to the Committee's comments.
EDO letter, dated September 28, 1992, responding to the ACRS report dated August 11, 1992, concerning NRC requirements that are marginal to safety.
The EDO letter was responsive to the Committee's comments.

EDO letter, dated September 23, 1992, responding to the ACRS e
report dated August 18, 1992, concerning severe accidents.
The Committee found the response weak.
Dr.
Catton will prepare a draft letter for ACRS consideration at the November 1992 ACRS meeting.
EDO letter, dated September 18, 1992, responding to the ACRS e
report dated August 14, 1992, concerning GSI 151, ATWS pump trip.
The EDO letter was responsive to the Committee's comments.
EDO letter, dated October 8,
1991, responding to the ACRS report dated September 17, 1992, concerning the BWR and Fermi-2 plant power uprates.
The EDO letter was responsive to the Committee's comments.
EDO letter, dated June 12, 1992, responding to the ACRS report dated May 13, 1992, concerning Evolutionary and Passive LWRs, the staff's requirements on the design and use of the' Post Accident Sampling System (PASS), the Committee found the EDO letter was responsive to the Committee's comments.

SUMMARY
/ LIST OF FOLLOW-UP AND OTHER MATTERS Dr. Shewmon will complete Mr. Wards term as Chairman when he e
leaves the Committee on November 4, 1992, and Mr. Carroll will assume the duties of the Vice-Chairman.
With regard to qualification of electrical equipment for license renewal, Mr. Michelson would like to know if the fire retardant coating on electrical cables is looked at to ensure that chemical reaction of the coating would not cause degradation of the cable.
(Mr. Igne is the Cognizant Engineer on this matter.)
e Mr.
Crutchfield,
- NRR, agreed to provide an official determination as to whether the Rules and Statutes will i
require one'or two ACRS reports for the ABWR as part of the certification process.
The staff is presently asking.for one ACRS report after the FSER is written, but before design certification and the final design approval, i.e.,
before hearings'and final Rule.
(Dr. El-Zeftawy is the Cognizant Engineer on this matter.)
i Dr. Kress wishes to know what the staff is planning to do with e
regard to assessing models (hopefully not every model) of the severe accident codes.
The EDO letter to the ACRS dated September 23, 1992 states "The NRC has put a contract in place
t 4
6 to provide an independent assessment and evaluation of models that are proposed for implementation in severe accident codes."
(Mr.
Houston is the Cognizant Engineer on this matter.)
e A progress report on the Multiple Systems Response Program (MSRP) should be scheduled for a future ACRS meeting. (Dr.
Savio is the Cognizant Engineer on this matter.)
Members of the Committee had neither comment nor plans to take e
further action regarding the September 22, 1992 letter to John Hoyle, Office of the Secretary, from Herbert Bardach.
The letter provided comments from Mr. Bardach that certain widely used computer codes were disposed to yield serious errors of j
underestimation of dose rates.
Dr. Wilkins will look at-this matter further as an item of personal interest.
(Mr. Igne is the Cognizant Engineer on this matter.)
e The Committee agreed to the following schedule for holding ACRS meetings for calendar year 1993:
