Engelken, Renional Adainistrator JLee Region V FROM: Harold R. Denton, Director Office of ttuclear Reactor Regulation SUPJECT: DIA9LO CANYON DESIGN VERIFICATION PROGRAt1 During the Comission raeeting on October 20, 1982 regarding the Diablo Canynn design verification progran the potential for prograixaatic deficiencies in the PG!.E design process was discussed, anonq other issues. The dialogue seemed to indicate that NRR and Region V have different view points on this issue (see page 92 through 98 of the transcript). I do not believe that we differ in our views, however some clarification should be helpful.

Your nemorandun to re of Septenber 15, 1982 addresses the potential need for expanding the scope of the prograra because of the above issue. I believe that the expanded progran for Phase I and Phase II, as proposed by the staff in SECY 82-414 and as sumarized in Figure 3 of the paper, is responsive to your concerns and will assure that any broad prograrvaatic ctJP iciencies in the design progran of PG3E and its contractors will be identified. In particular, 4 the expansion of the prograta will deterraine if the QA deficiencies thus far identified in design activities also exist for construction activities.

If you have any comments on this matter please advise NRR promptly.

4 32. DE5 DON: Bob had taken a real interest in 5 this aspect and saybe he would like to talk about it.

17 apparent lack of top sanagenent involve =ent in the 18 1:plesentation of Q A at least in certain areas.

19 . .This did cast some sort of a shadow over the 20 general area of C A, quality ass'urance, and this had been 21 as issue raised by the intervenors. It had been raised 22 ,b? the intervenors in hearing or prior to the hearing 23 and it was denied as a contention, as I recall it, but l

24 it was a lingaring concarn with them. l l

  1. ~ 1 position, since ve had been inspecting that plant 2 through its construction , o f def endin; the QA for 3 construction. I though t it was appropriate for part o_f 4 the reverification prograa to cover quality assurance 5 f or construction even though our inspection progras had 6 indicated that the construction OA p rog ram was an 7 adequate program and was at least average and perhaps e

8 better than average than th e progras that we had seen 9 for construction at other facilities. But we did feel 10 that it vould be a further reassuranc_a that there vers 11 no serious construction errors built into the plant.

12 CO MM ISSIO N ER AHEARNE: So that your oc_ 13 re ossendation though, which as I recall was sometime 14 around May, was not based upon kncan but unwritten 15 conclusions that Region 7 inspectors had reached?

16 52. ENGELKEN : That is corre::. It was just 17 further assurance which we felt was apprcpriate. The 18 reco :endation, incidentally, was made to M r. Denten by 19 e in a sesorandca dated March the 29th. That letter 20 subsequently be:ana public and was picked up by other 21 parties and given some esphasis.

22 205%ISSIONER AHEARNE: On Septecher 15th o f 23 this year Ycu wrote a letter to Harold and you made a 24 romment in it. Iou say that "We offer the following 25 consents and quest. ions." No. 3, and this is from l

95 y 1 Enclosure 6, but in No. 3, you asked the question 2 "Should the scope of the Phase II progras plan be 3 re-examined?"

4 You go :n to say that th e Reedy findings, S "Iheir combination with the licens ee audit findincs 6 suggests th e possibility of broad programmatic 7 deficiencias in the licensee's design progran and__

  • 8 certain of their contractors. Based on this, it may be 9 appropriate to re-exa:ine the scope of the initial to. verification sa:ple defined in Phase II."f

.11 Could you expand on that a little hit and 12 th en , Harold, could you cossent on, you had just

  • 13 previously said you felt that what you have proposed is

p 14 correct and whether it seets 2ob 's concerns.

15 Bob, rould you expand on that?

16 1R. ENCELKIN: I thin k that we are principallf 17 talking in terns of the numbers of contractors that 18 vould be sampled with respect to C A audits and we simply 19 s a d e the sughestion that perhaps this should be 20 considered in evaluating'the Phase II progran plan. I 21 think that we made the su;;e stien to NRR and Mr. Denton 22 f :t their consideration and I think perhaps for the 23 con sideration of the ID7? if %:. Denton agreed that it 24 was something that they should ronsidar.

a 8 MR. ENGELKEN: Well, tha t wa s another 9 consideration. Ies, the var the audits were conducted,

~

10 if there was no for:al QA p rogras, then the Reedy 11 organization did no further review of the Q A program ,

12 but reviewed the practices that vere actually, applied.

ee- 13 I think the succestion here is that without further 14 revievias the formal QA program, then all of the known 15 deficiencias nar not be detected.

  • 16 I also think that we had sonevhat of a Legal 17 problem vich the wording in th e le,tter which suqqested 18 that all contractors would be reviewed and the proposal 19 by Reedy was to just reviev certain enes. I don't think 20 that we hai any real technical prob'lec there. It was 21 scre a proble,m cf whether it set the verding of the 22 letter.
