REACTOR SAFEGUARDS Mr. L. Manning Muntzing Director of Regulation U. S. Atomic Energy Commission Washington, D. C. 20545 g4 N-50 447
Dear Mr. Muntzing:
I have reviewed your letter of February 12, 1974, which expressed concern over delays in the review' of GESSAR and which requested proposed actions by the General Electric Company to avoid further delays. As discussed with you previously, I egard our standardization efforts, which include the GESSAR work, to be of highest priority.
I, too, am greatly concerned
'that atihis stage of the GESSAR review the Staff has found it necessary to extend the GESSAR review schedule by fcur weeks.
i Your letter identified a number of causes for the schedule delay - a late transmittal of a portion of the Staff's questions, a subsequent late trans-mittal of responses by_ GE, and the late submittal by GE of design changes to certain control and protection systems.- We agree that some of the delay can be attributed to these factors. However, design details and analyses have been requested by the Staff to a depth and scope far beyond the Commis-sion's '" Standard Format and Content of Safety Analysis Reports for Nuclear Power Plant s. " Some of the information being requested cannot be made available until the final design is complete and its absence has been a sig-nificant contributor to the delay.
Two key areas appear to us to warrant special attention if your revised schedule for GESSAR is to be achieved. We have found that a number of design changes in GESSAR have resulted from the release by the AEC of more than thirty new Regulatory Guides since GESSAR was filed with an attendant impact on the review schedule. We anticipate that the AEC will continue to offer this guidance to the industry by issuing other new guides; however, a need exists to determine which of these AEC Regulatory Guides are to be incorporated in the standardized desi; n described in GESSAR.
Additionally, the standardization program has iientified an apparent need by the Staff for new types of information, that is, interfacing requirements.
We continue to have difficulty providing information in this area and need the Staff to clearly identify and define the type of information needed.

/
During the next few weeks we will intensify our own engineering efforts and work closely with appropriate segments of your Staff to bring the GESSAR review to a succes sful conclusion on schedule. We believe that a concerted effort by GE and your Staff should be made to identify all Regulatory issues so that early resolution can be obtained. In particular, I propose a meeting during the week of March 11, 1974 prior to your release of the second round of questions on March 19, 1974 with the following agenda:
1.
Identification and resolution of the current outstanding Staff review concerns related to GESSAR.
2.
Identification and definition of any supplementary Regulatory require-ments which must be addressed in GESSAR.
3.
Definition of the appropriate level of detail to be contained in GESSAR and required by the Staff to bring the review to a conclusion.
4.
A schedule for future review meetings to focus on critical path topics, such as instrumentation and interfaces.
In reviewing the revised schedule attached to your letter, we note that the end date for the GESSAR review was changed to 12 /12/74. However, we understand that this is a typographical error and actually should be 12/2/74.
We appreciate the sincere efforts now being placed on the GESSAR review by the AEC Staff. With continued, dedicated work by each of our organizations, this major milestone of our overall standardization program can be achieved within the revised schedule.
