This is the first day of the meeting of the 5 AP1000 Reactor Subcommittee, the first day of this 6 two-day series. We are a standing Subcommittee of the 7 Advisory Committee on Reactor Safeguards, or ACRS. 8 I'm Harold Ray, Chairman of this Subcommittee. 9 Other ACRS members in attendance today are 10 Sanjoy Banerjee, who will join us shortly, Dennis 11 Bley, Mario Bonaca, Bill Shack, and Mike Ryan. I 12 don't think I've overlooked anyone. Tom Kress, an 13 emeritus of the ACRS and former Committee Chairman is 14 also seated here at the table with us today, and he is 15 invited consultant to the Subcommittee for this work. 16 Mike Lee of the ACRS Staff is a Designated 17 Federal Official for this meeting, and he's also 18 joined by Weidong Wang, also of the ACRS Staff. Sorry 19 for the German pronunciation. 20 The purpose of this Subcommittee meeting 21 over the next few days will be continue with a review, 22 and discussions concerning Revision 17 of the Design 23 Control Document, describing a standard plant design 24 for the AP1000 pressurized water reactor. The most 25 recent Subcommittee meetings on this subject were held NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W. (202) 234-4433 WASHINGTON, D.C. 20005-3701 www.nealrgross.com 7 1 this past July. 2 By way of background, we're reminded that 3 the Westinghouse Electric Company submitted Revision 4 17 of the DCD to the U.S. Nuclear Regulatory 5 Commission, and that since its submittal, the NRC 6 Staff in the Office of New Reactor Licensing have been 7 engaged in review of those revisions, and have 8 complemented this review with meetings with 9 Westinghouse representatives, and members of the 10 AP1000 Design Center group. 11 Upon completion of this review, the Staff 12 will issue a Final Safety Evaluation Report related to 13 the certification of the revised standard design. As 14 part of the design certification process, the NRC 15 Staff are required to obtain the views of the ACRS. 16 Today, and in subsequent meetings, this Subcommittee 17 will hear from the Staff on the results of their 18 review of the DCD Amendments. And we will hear, also, 19 from the Applicant. 20 I understand that copies of the detailed 21 meeting agenda have been made available. When looking 22 at the agenda, you will see that each chapter, a 23 standard briefing template will be followed that 24 consists, essentially, of three elements, a discussion 25 of the Revision 17 changes to the DCD by NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W. (202) 234-4433 WASHINGTON, D.C. 20005-3701 www.nealrgross.com 8 1 representatives of Westinghouse, and the significance 2 of those changes over the NRC certified Revision 15. 3 A discussion of the Draft SER prepared by the NRC 4 Staff corresponding to the DCD Chapter that has just 5 been described by the Applicant, and a discussion of 6 any applicable open items by the Staff. 7 In summary, this Subcommittee intends to 8 gather information, analyze relevant issues and facts, 9 and formulate proposed positions, and actions, as 10 appropriate from this meeting for deliberation by the 11 Full Committee of the ACRS at a later date. We may 12 also determine additional meetings on one or more of 13 the items discussed over the next two days merits 14 further discussion, and study by the Subcommittee. 15 The rules for participation in today's 16 meeting have been announced as part of the notice of 17 this meeting previously published in the Federal 18 Register. And I'll note that that notice also 19 indicated we would begin at 8:30. We've had a number 20 of changes, including the room location. We're 21 starting at 9:00 today. And, I guess, tomorrow that 22 will be the same. Is that right? 23 MR. LEE: 8:30. 24 CHAIR RAY: 8:30 tomorrow. Okay. So, 25 we'll all be on time at 8:30, as we were this morning. NEAL R.

I understand that we have a 5 speaker phone in operation today, and we'll ask that 6 those individuals participating in this Subcommittee 7 over the telephone bridge lines place their speaker 8 phones on mute. 9 As stated earlier in the Federal Register 10 Notice, a transcript of this meeting is being 11 prepared, and will be made publicly available in the 12 near future on the ACRS website; therefore, we request 13 that anyone wishing to address the Subcommittee on the 14 record use one of the microphones located throughout 15 the meeting room. We request that you first identify 16 yourself, and your affiliation, and speak with 17 sufficient clarity and volume so that your comments 18 may be readily heard, and recorded. 19 We also request that if you're in 20 possession of cell phones, or some other type of 21 electronic paging device, you adjust it to the silent 22 mode, or, alternatively, turn it off so as not to 23 interrupt the conduct of the meeting.
