Subject:

NRC Draft Commercial Grade Dedication Inspection Procedure l' t Consolidated Edison is pleased to provide comments- in-response to the rewest for comments included in the notice [ of the Connercial Grade Procurement and Dedication Workshop I which appeared in the Federal Register dated March 19, 1993 ' (58 FR 15167). In that request, comments were invited on the , draft inspection procedure 38703, entitled " Commercial Grade Procurement Inspection". Comments were requested by May 21, { 1993. (,

                                                                                                                                ~i The Nuclear Management and Resources Council (NUMARC) has submitted comments by their letter dated May 17, 1993.                                          We have reviewed their letter and endorse their comments.                                           In             !

addition, we also offer general comments on the. draft procedure, as 'well as comments directed to specific statements in the draft procedure, provided in Enclosure 1. i Overell, we are concerned that the NRC's expectations for licensee documentation and testing in order to dedicate i commercial grade items apparently exceeds requirements l imposed in the past on 10 CFR 50 Appendix B vendors who have , supplied equivalent items. [ We believe that this additional effort, while adding substantially to our procurement costs  ! and schedules, would not provide commensurate improvements in  ! the level of assurance that commercial grade -items would j perform as expected. Under the. draft inspection' approach, we may order testing which would not ' meaningfully enhance our knowledge about component perfcrmance, end expend effort to i create volumes of unnecessarily detailed documentation. The solution to this problem would appear to be performance- .t based inspections, initiated in response to an industry or. j licensee event, focused more on'results than on precedures. l We believe .that the subject draft procedure is heavily- .( weighted toward evaluating process and procedural details, and incorrectly emphasizes documentation over performance. ') l Indeed, the subtle but~ pervasive philosophy ' of the draft j inspection procedure could elicit an excessive commitment of' NRC staff inspection resources f to commercial grade procurement issues. . { i 9305280263 930520 PDR PR { MISC 58FR15167 PDR .

[ testing than would be provided under a Quality Assurance program.which meets  ! j the requirements of 10 CFR 50 Appendix B. This represents a backfit., for  ! which there has been no demonstration of necessity. To the extent the NRC's premise is that dedicated commercial grade items contribute to more and , graver safety significant problems than items procured from vendors who meet  ! Appendix B requirements, a full explanation should be afforded. , l General The draft inspection procedure is highly detailed and prescriptive. It i anticipates detailed documentation of every decision and action during the  ! procurement and acceptance process for dedicated commercial grade items. The motivation appears to be that licensees take over responsibility for j certain functions normally performed by the vendor when the vendor has an Appendix B program. .. However, such detailed documentation has not normally j been required under Appendix B programs. Appendix B requires only that  ; certain activities be controlled, not that every consideration be documented 4 in detail. It appears that the proposed inspection procedure would look for  ! licensee documents that are more specific and detailed than would generally { ( be found in Appendix B vendor records, and go far beyond demonstrating that l applicable activities are adequately controlled. This requirement would j therefore represent a backfit, for which no supporting justification has  ; been put forth. 1 General ) Consideration should be give to amending the draft inspection procedure to ! [ include items purchased from vendors with Appendix B QA programs. The I imposition of any requirements for the licensee (when the item is procured i commercial grade and dedicated) that would not also have applied to a vendor > , who met Appendix B requiremente at the time of the original purchase should  ! be deleted. i j General t ( 1 The flow charts shown - at the workshop did not match the draft procedure.  ! Because these flow charts would be a helpful training tool, they should be  ; reviewed in detail against the procedure as issued. Consideration should  ! be given to including flow charts in the procedure. I I General

A great deal of information and experience has been gained by the industry i and the NRC on procurement issues in recent years.

i I Due to the many variables in the procurement process, and the need for 'I application of judgement, it is important that inspectors receive training  ! in this procedure. For the same reasons, there should be central oversight j of inspection results to assure consistency among Regions. The goal of i training and central oversight should be to keep the focus on the safety significance of results and to avoid overemphasis on programmatic rigidity 3 and detailed documentation. ~ 38703A-02.04 l! l Guidance is needed for the NRC inspectors when the commercial grade item of  ! interest was dedicated prior to the industry's commitment to the procurement ' initiative. ~ 38703A-02.04e i t.

             "Any documentation...should be validated by a commercial grade ' survey, source verification, or methods discussed in Section 6 of Appendix A to                         !

Inspection Procedure 38703." Should be changed to "...should have an established basis for its validity. i Methods for establishing a basis for validity may include a commercial grade - vendor survey. source verification, history of spot check results during i receipt inspections, history . of installed performance, or other suitable means commensurate with the safety significance and complexity of the item." fi 38703B-01

            " Verify that the licensee's process for dedicating CGIs... ensures that CGIs will perform their intended safety function."

Recommend changing " ensures

• to ' appropriately contributes to assurance".

The original' wording is too broad, and " ensure" 'is too absolute as a concept. Dedication is a procurement and acceptance process. The Appendix  ; B requirements clearly do not intend procurement and initial acceptance to

          -bear the full burden of assuring performance ~ of the intended safety                           ,

function. The other elements of the Quality Assurance program also contribute to this assurance. , t 38703B-02.02

           "... select approximately twenty' dedication packages for review.'                              !

Instead of a definite number of packages, alternative approaches such as' selecting a percentage or a statistical sampling, not to exceed 20, should be acknowledged as appropriate. The sample should be balanced to' assess the l program results and not be biased to focus on failures.  !
