81 1 October the 9th and 10th, we went to the site to 2 review their calculations.

O3__

3........_3We asked six questions during that audit, 4 and you can see the full response on November the 5 14th. One of those responses to audit question 387 6 did not fit our needs. So we sent and REI to them 7 further address the issue on November 27th.

8 We received that response on December 9 llth, the response to the RAI on December llth. We've 10 had a few calls to discuss this issue. The major one 11 was on December 18th. At that time VY sent some 12 disconnect there and requested a~face-to-face meeting 13 to help facilitate the resolution of this highly 14 technical issue.

15 So we had a meeting on January 8th. At 16 that time the applicant agreed to submit some plans 17 specific, confirmatory comments to the analysis, and 18 that's where we stand today.

19 MEMBER ARMIJO: And that submittal has 20 been made now?

21 MR. ROWLEY: That submittal was made.

22 That was made on January 30th, which was just a few 23 days ago. So we've had a preliminary review of what 24 they submitted, and I'd like Dr. Chang to take over

  • 25 here to discuss that.

82 1 DR. CHANG: Thank you.

2 My name is Ken Chang. I'm the Branch 3 Chief for Engineering Review Branch at the Division of 4 License Renewal.

5 I've been involved in every audit, every 6 conference call. Every year I have public meetings on 7 this. So I hope I can address this issue today in a 8 satisfactory manner, but in the March meeting'will be 9 in,a complete manner.

10 The plant specific confirmatory EF 11 analysis is by definition the confirmatory year 12 analysis. It is not the EAF analysis. The EAF 13 analysis was submitted, was contained in the december 14 llth submittal.

15 The confirmatory analysis, the purpose of 16 that is to use the typical ASME methodology without 17 any fancy tools or anything to do the analysis to show 18 that the December 11 analysis is conservative. So, 19 therefore, we are result driven. As long as the CUF 20 is less than 1.0 by a classical ASME analysis, even 21 you say state of art analysis, that should be okay.

22 And we have enough time to 'perform the 23 review of their benchmarking calculation.

24 Specifically for Vermont Yankee, we are not endorsing 25 anything beyond Vermont Yankee from that review. That NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

87 1 And that's where we are.

2 MR. ROWLEY: Our Section 4 review is 3 ongoing. As Ken said, they just yesterday provided 4 some additional information about the nozzle 5 configuration differences, and then some additional 6 information regarding the chemistry impact of the Fen 7 value. Staff's review of Section 4 is thus 8 incomplete, and we will have this completed over the 9 coming weeks in order to discuss this in our March 10 meeting.

11 Here are the three license conditions that 12 we applied thus far.

13 Questions?

14 VICE CHAIRMAN BONACA: Questions for the 15 staff?

16 Nothing. Thank you for the presentation, 17 and I think we have three members of the public who 18 want to speak. Do you have a list of those?

19 CHAIRMAN SHACK: Yes.

20 MEMBER ARMIJO: Just before, I have one 21 quick, question for Mr. Modes. He mentioned about 22 glowing reports about the-drywell and torus shells.

23 MR. MODES: Yes.

24 MEMBER ARMIJO: Did you find that those 25 were exaggerations or were those components in good NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
