MEMORANDUM FOR: Charles L. Miller, Director Standardization and Life Extension Project Directorate Division of Reactor Projects III/IV/V and Special Projects l

SUBJECT:
SUMMARY
OF MEETING WITH NUMARC HELD ON APRIL 9, 1990 TO DISCUSS ITAACS The. subject meeting was held at the NRC Office to discuss the status and future actions to be accomplished by the NUMARC working group on the Inspection, Testing, Analysis, and Acceptance Criteria (ITAAC) to support the design t-certification for future standardized plants. NUMARC has been in the process of ceveloping a generic ITAAC which would provide a basic format and guidance to potential applicants for design certification.
Participants in this meeting are listed in Enclosure 1.
The following is a summary of items discussed at the meeting:
1 1.
The level of design detail necessary and the degree of standardization to be achieved under a license per 10 CFR Part 52 was discussed with respect to both the design certification and ITAACs. The NRC feels that the subject of level of detail and ITAACs are closely related. NUMARC agreed by stating that they have incorporated their efforts on the level of detail into the development of the ITAAC. NUMARC believes that the ge'neric approach provides an acceptable framework for the specific ITAAC submittals, with the actual first vendor application providing an itera-i tive process which will create more specific details.

NUMARC has proposed a two tier approach applicable to the design and ITAAC. Tier 1 would include that information which supports the actual licensing basis for certification and would be part of the design certifi-i cation _ rule. The specific information to be incorporated in Tier I must be determined by the NRC. However, for the NUMARC approach, Tier 1 would i
l be compromised predominantly of those items having analysis-type accep-tance criteria. -Tier 2 would include design details which flow from the implementation of the licensing basis and provide assurance that the licensing basis criteria are being met. The items in Tier 2 as proposed by NUMARC could be changed subject to the requirements of 10 CFR 50.59.
In this regard, the Standard Safety Analysis Report would be a Tier 2 document, except for those Tier 1 licensing bases which are intermingled in the document.
The Tier 1 licensing basis would include, for example, commitments to industry codes and standards and NRC regulations. Changes to the licens-ing bases could only be obtained through a formal process under 10 CFR Part 50.12.
3 It is the NRC's understandin that the NUMARC ITAAC will be generic and will include such items as (g) a list of basic program elements with 1
clarification, as necessary; (2) a suggested format and content of vendor specificsubmittals;(3)detailedex6mplesforPWRandBWRcases; (4) details for the processing of nonconformances which are outside of the acceptance criteria;.and (5) interface criteria with the NRC such as inprocess reviews.
NUMARC also indicated that the ITAAC would present a matrix approach, incorporating both generic / topical-as well as system level ITAAC. The NRC stressed practical cases should be included with the submittal. -This would allow comparison and assist in evaluating the practicality of implementation.
NUMARC stated that the Quality Assurance and Quality Control program aspects may be the subject of a separate ITAAC, since this program is important to providing assurance and evidence that the processes,are working. The NRC inquired about the interface of ITAAC with other items of operational consideration such as the Facility Technical Specifica-tions, operating procedures, design basis and baseline inspection and testing. NUMARC indicated that the present ITAAC plan does not address these areas, but these would be evaluated and discussed in the future.
The NUMARC prepared ITAAC will have the status of a guidance document.
This would allow for a degree of individuality on the part of each vendor.

The NRC staff addressed the possibility of requiring the submission of
~1nsta11ation and Construction Specifications to aid the review process.

These documents would provide process parameters, attributes, and toler-l
'ances. NUMARC stated that.these documents could be made available.
