Three, Safety Evaluation Report 14 associated with Revision 19 of the AP1000 Design 15 Control Document Amendment. Four, Draft Final 16 Revision 2 to Reg Guide 1.115, "Protection Against 17 Turbine Missiles." And, five, preparation of ACRS 18 reports. 19 This meeting is being conducted in 20 accordance with the provisions of the Federal Advisory 21 Committee Act. Dr. Antonio Diaz is the Designated 22 Federal Official for the initial portion of the 23 meeting. 24 Portions of the session dealing with the 25 Safety Evaluation Report associated with Revision 19 NEAL R.

Mr. Adrian Heymer from the Nuclear Energy 8 Institute has also requested time to make an oral 9 statement regarding this session. 10 In addition, Dr. Susan Sterrett has 11 requested time to make an oral statement regarding the 12 session on the SER associated with Revision 19 of the 13 AP1000 DCD Amendment. 14 There will be a phone bridge line. To 15 preclude interruption of the meeting, the phone will 16 be placed in a listen-in mode during the presentations 17 and Committee discussion. At the appropriate time, 18 the phone will be open to allow Dr. Sterrett to 19 provide her comments to the Committee. 20 A transcript of portions of the meeting is 21 being kept, and it is requested that the speakers use 22 one of the microphones, identify themselves, and speak 23 with sufficient clarity and volume so that they can be 24 readily heard. 25 We will now move to the first item on the NEAL R.

And 3 I call on Mr. Jack Grobe to begin the presentation. 4 Jack? 5 MR. GROBE: Thank you very much. 6 We certainly appreciated the opportunity 7 a couple of weeks ago to spend several hours with the 8 Subcommittee. The slides we've prepared today are a 9 very brief set of slides that overarch or provide the 10 overarching recommendations. We look forward to the 11 questions that you may have come up with studying our 12 report in the last two weeks, and new questions that 13 might come up during the course of the meeting. Next 14 slide, please. 15 Again, the Task Force was led by Charlie 16 Miller, who is on the golf course somewhere. He's 17 retired. Nathan Sanfilippo is not here with us today. 18 He's up meeting with Region I in the State of New 19 Jersey on Fukushima Lessons Learned, and Gary Holahan 20 is trying to license new reactors. He had a number of 21 important meetings that he couldn't reschedule, so I 22 apologize for those two individuals not being with us, 23 but the rest of the Task Force is here today. 24 High-level summary, the Near-Term Task 25 Force concluded that a similar sequence of events is NEAL R.

And we 3 have existing mitigating measures here in the United 4 States that provide additional capability, and reduce 5 the likelihood of core damage if they remain available 6 during the event. 7 The Task Force further concluded that 8 there's no imminent risk, and what that means is 9 there's no need to take action to curtail operation of 10 reactors or impose immediate changes to the licensing 11 structure for the reactors. However, there's a number 12 of recommendations; 12 overarching recommendations to 13 enhance safety, including some near-term interim 14 actions. 15 The 12 overarching recommendations, the 16 first one -- 17 CHAIRMAN ABDEL-KHALIK: Jack, before we get 18 into the details of the recommendations, let me just 19 ask a big picture question. 20 Would you agree with the statement that 21 the recommendations of the Task Force were not based 22 on detailed evaluation of the progression of the 23 Fukushima accident; instead, they were based on facts 24 that became self-evident to knowledgeable individuals 25 as a result of the Fukushima accident.

GROBE: I look for my comrades here to 2 provide additional insights, but I would say it's 3 between those two. We certainly had people on the 4 ground in Japan, and we have had since the event 5 occurred. We met with those people as they came back 6 from Japan to gain insights. We asked questions 7 regarding, for example, specifically the functioning 8 of the hardened vents, and got detailed information 9 back from our team in Japan on how the vents were 10 designed at Fukushima, and the attempts that they 11 made.
