Exelon Backfit Appeal Panel Preliminary Findings FOR COMMENT - OWQ P~fil El@eisieAal h:terrn1I NAE l:f3C 8ul9

All, Consistent with the plan we presented last week, attached are the preliminary findings of the Exelon Backfit Appeal Panel. The Summary from the Preliminary Findings is reproduced below. The preliminary findings were discussed briefly with the OEDO for their awareness.

As indicated in our completion plan, the panel would appreciate any comments on, or additions to: the documents sited; their interpretation and intent; or the understanding of the backfit rule compliance exception.

Comments would be appreciated by August 9, 2016, but can be accepted as last as August 15, 2016. The panel will also be available for discussion any time before August 15, 2016.

Comments will be reflected or acknowledged in the panel's final report and recommendations to the EDO.

The Preliminary Findings document attached is an internal, pre-decisional document at this time. Both Exelon and NEI declined offers for a public meeting on this issue.

Gary ... for the panel

-Steve West

-Tom Scarborough

-Michael Spencer

-Theresa Clark In summary:

The NRA 2015 compliance backfit finding (October 9, 2015 letter to Exelon) is predicated on the following positions (emphases added):

• "water relief through a valve that is not qualified for water relief will cause that valve to stick in its fully open position"

• "the licensee ... has not applied the single-failure assumption"

• "nor have they provided ASME water qualification documentation for the PSVs ... the ASME ... original Overpressure Protection Report ... inservice test history ... including both water and steam tests" However, none of these positions were "known and established standards of the Commission" in 2001 or 2004 for determining when it was appropriate to assume a failure of PSVs to reseat. In fact, they were not "known and established standards of the Commission" in 2005 or 2006 or 2007.

Moreover, two of these positions do not appear to be "established standards of the Commission" at present, since the call for use of the single failure criterion first appears in proposed 2015 draft Revision 1 to RIS 2005-029, and the call for ASME certification first appears in the Exelon compliance backfit. The panel concludes that the standard in place in 2001 and 2004 and at present is simply that the probability of failure of a Pressurizer Safety Valve (PSV) is sufficiently small, based on well-informed staff engineering judgement, and that the use of the word "qualified" or "qualification" implied only a general demonstration of capability, such as in the EPRI testing done in response to TMI Action Plan Item 11.D. 1.

The panel concludes that, in 2001 and 2004, the staff was not misinformed nor did it "err" in approving the Byron and Braidwood power uprates ... nor was it in error in approving other similar cases (e.g. Beaver Valley in 2006). The 2015 staff positions taken to support the compliance backfit finding represent new and different staff views on how to address potential PSV failures following water discharge. Although they represent well-intentioned staff positions that could provide additional safety margin, they do not provide a basis for a compliance backfit.

2

The panel's findings therefore support the Exelon backfi1 appeal.

In addition to the specific finding relating to the backfit appeal, the panel believes it is important to acknowledge that water discharge through a PSV not specifically designed for such service is undesirable and should be minimized or avoided as a matter of conservative engineering and prudent operations. The panel concludes this while fully aware that the event sequence being considered appears to be of little safety significance (the panel has requested RES analysis to confirm this belief). Operator training and emergency procedures to terminate the event before pressurizer filling, as well as the use of power-operated relief valves rather than relying solely on PSVs, are clearly preferred, whether they form the facilities' UFSAR licensing basis or not.

The panel has not (at this time) formed any views on whether a backfit on this topic could be justified as "adequate protection" or "cost justified"; or whether a "forward-fit" staff position is appropriate or not.

Thanks for this document. My preference (though I know I am low on the totem pole) on a meeting time tomorrow would be later in the day since I have to present at an OIG exit meeting at 10am. I won't really have a lot of time to review this document before that meeting but look forward to diving in after the meeting! Also FYI that Sheldon will be on annual leave tomorrow but back in the office on Wednesday.

Exelon Backfit Appeal Panel Preliminary Findings FOR COMMENT - 000- Pi E-Cletlslo11al - l11tE, ..nl f4RC Iese fzih~l 1

All, Consistent with the plan we presented last week, attached are the preliminary findings of the Exelon Backfit Appeal Panel. The Summary from t he Preliminary Findings is reproduced below. The preliminary findings were discussed briefly with the OEDO for their awareness.

As indicated in our completion plan, the panel would appreciate any comments on, or additions to: the documents sited; their interpretation and intent; or the understanding of the backfit rule compliance exception.

Comments would be appreciated by August 9, 2016, but can be accepted as last as August 15, 2016. The panel will also be available for discussion any time before August 15, 2016.

Comments will be reflected or acknowledged in the panel's final report and recommendations to the EDO.

The Preliminary Findings document attached is an internal, pre-decisional document at this time. Both Exelon and NEI declined offers for a public meeting on this issue.

Gary ... for the panel

-Steve West

-Tom Scarborough

-Michael Spencer

-Theresa Clark In summary:

The NRA 2015 compliance backfit finding (October 9, 2015 letter to Exelon) is predicated on the following positions (emphases added):

• "water relief through a valve that is not qualified for water relief will cause that valve to stick in its fully open position"

• "the licensee ... has not applied the single-failure assumption"

• "nor have they provided ASME water qualification documentation for the PSVs ... the ASME .. .original Overpressure Protection Report ... inservice test history ... including both water and steam tests" 2

However, none of these positions were "known and established standards of the Commission"' in 2001 or 2004 for determining when it was appropriate to assume a failure of PSVs to reseat. In fact, they were not "known and established standards of the Commission" in 2005 or 2006 or 2007.

Moreover, two of these positions do not appear to be "established standards of the Commission" at present, since the call for use of the single failure criterion first appears in proposed 2015 draft Revision 1 to RIS 2005-029, and the call for ASME certification first appears in the Exelon compliance backfit. The panel concludes that the standard in place in 2001 and 2004 and at present is simply that the probability of failure of a Pressurizer Safety Valve (PSV) is sufficiently small, based on well-informed staff engineering judgement, and that the use of the word "qualified" or "qualification" implied only a general demonstration of capability, such as in the EPRI testing done in response to TMI Action Plan Item 11.D.1.

The panel concludes that, in 2001 and 2004, the staff was not misinformed nor did it "err" in approving the Byron and Braidwood power uprates ... nor was it in error in approving other similar cases (e.g. Beaver Valley in 2006}. The 2015 staff positions taken to support the compliance baclctit finding represent new and different staff views on how to address potential PSV failures following water discharge. Although they represent well-intentioned staff positions that could provide additional safety margin, they do not provide a basis for a compliance backfit.

The panel's findings therefore support the Exelon backfit appeal.

In addition to the specific finding relating to the backfit appeal, the panel believes it is important to acknowledge that water discharge through a PSV not specifically designed for such service is undesirable and should be minimized or avoided as a matter of conservative engineering and prudent operations. The panel concludes this while fully aware that the event sequence being considered appears to be of little safety significance (the panel has requested RES analysis to confirm this belief). Operator training and emergency procedures to terminate the event before pressurizer filling, as well as the use of power-operated relief valves rather than relying solely on PSVs, are clearly preferred, whether they form the facilities' UFSAR licensing basis or not.

The panel has not (at this time) formed any views on whether a backfit on this topic could be justified as "adequate protection" or "cost justified"; or whether a "forward-fit" staff position is appropriate or not.

The NRA paper is clear. weir supported, and well written. I still believe the backfit should be conducted in accordance wi1h MD 6.4 as a generic backfit.

O, ,ly Good Friday afternoon, The attached document is provided as an FYI The OEDO backfit review panel provided NRR/DSS technical staff with an opportunity to comment on their preliminary conclusion, which is to overturn the backfit. DSS coordinated an NRR response to the OEDO panel, which is attached. I anticipate that you'll find it to be an interesting read and I think a compelling case is made by DSS. We'll see what the OEDO panel thinks.

Anne, T im -

This morning, the Panel briefed Bill, Michelle and John on our review of the Braidwood and Byron backfit appeal. The Panel recommended that Exelon's appeal be denied. We also recommended that staff review the general strategy, used by PWR licensees, of relying on PORVs or PSVs to relieve water during mass addition events to determine if further generic actions are warranted in light of the staff position communicated in the October 9, 2015, backfit letter.

Our review and recommendations are documented in ADAMS ML 16082AS4~. Details on the basis for the second recommendation are documented in a memo from Tony Gody to me (ADAMS MLL60sJ A405).

Bill was supportive of the Panel's recommendations. Next step will be to write a letter to Exelon on the appeal decis ion; Alex Garmoe will have the lead. That letter will make no mention of the potential generic issue. The potential generic issue will likely be turned over to DSS for further consideration.

RE: Question about upcoming briefing of Mike Johnson on Exelon backfit appeal

Eric, Marissa, Bill, and I met on Friday in advance of the briefing. Based on his understanding of what Mike Johnson is looking for, Bill's preference is that the group remain small and not include DSS. Our impressions are that this is a situational awareness type of conversation that will be focused on the appeal process rather than the initial backfit. Please let me know if you have any questions and I apologize for cycling your organization late last week.

The key for EDO and DSS representatives at the briefing will be to discuss the circumstances and facts and to not appear to influence Bill's decision. I think it would be an overall benefit for someone from DSS to be present to address technical questions that might come up.

Eric, On Tuesday, May 3 at 4:30pm there is a briefing requested by Mike Johnson on the Exelon backfit appeal. Our intention is to provide a fairly high level overview of the backfit, the appeal, the appeal process and conclusions, and what might come next. Since DSS identified the initial issue and issued the initial backfit, we'd appreciate if someone from DSS could attend the briefing with us in case any questions about the underlying technical issue come up. Any support is greatly appreciated.

As Marissa mentioned yesterday, it would probably be a good idea to have someone from DSS that could assist with any detailed questions about the technical issue since they issued the initial backfit. I'll check with DSS.

Re: Question about upcoming briefing of Mike Johnson on Exelon backfit appeal Thanks, Alex. I didn't know the specific time, but I'll pull it off Mike's calendar now that I do.

I'm guessing Mike will want to focus on the use of the backfit criteria and the error that is being cited. I gave him a copy of the draft in ADAMS, with the understanding that it will be updated more to address Bill's comments, so you can expect that he will be aware of the basics. He may also be interested in the public meeting held a while back, as well as the appeal process (if it happens).

I'll check with him on the details and get back with you if l hear anything different. Thanks!

RE: Question about upcoming briefing of Mike Johnson on Exelon backfit appeal

Eric, Marissa, Bill, and I met on Friday in advance of the briefing. Based on his understanding of what Mike Johnson is looking for, Bill's preference is that the group remain small and not include DSS. Our impressions are that this is a situational awareness type of conversation that will be focused on the appeal process rather than the initial backfit. Please let me know if you have any questions and I apologize for cycling your organization late last week.

RE: Question about upcoming briefing of Mike Johnson on Exelon backfit appeal

Eric, I spoke with Theresa from the EDO's Office and Adam Gendelman from OGC. The general consensus is that it should not be a problem for DSS to be present at the briefing. The key for EDO and DSS representatives at the briefing will be to discuss the ci rcumstances and facts and to not appear to influence Bill's decision. I think it would be an overall benefit for someone from OSS to be present to address technical questions that might come up Alex From: Oesterle, Eric Sent: Wednesday, April 27, 2016 8:46 AM To: Garmoe, Alex <Alex.Garmoe@nrc.1;ov>

FW: Question about upcoming briefing of Mike Johnson on Exelon bacl<fit appeal Importance: High Eric, On Tuesday, May 3 at 4:30pm there is a briefing requested by Mike Johnson on the Exelon backfit appeal. Our intention is to provide a fairly high level overview of the backfit, the appeal, the appeal process and conclusions, and what might come next. Since DSS identified the initial issue and issued the initial backfit, we'd appreciate if someone from DSS could attend the briefing with us in case any questions about the underlying technical issue come up. Any support is greatly appreciated.

Thanks, Alex 2

FW: Question about upcoming !briefing of Mike Johnson on Exelon backfit appeal Marissa, Mirela, and Sheldon.

I asked T heresa Clark if we could anticipate any specific interests ahead of next week's briefing and her reply is below. It sounds like we'll be on the right track if we prepare for an overview of the initial backfit, licensee's appeal, the process we used to review the appeal. and what might come next (the licensee might appeal the decision to the EDO). As Marissa mentioned yesterday. it would probably be a good idea to have someone from DSS that could assist with any detailed questions about the technical issue since they issued the initial backfit. I'll check with DSS.

Re: Question about upcoming briefing of Mike Johnson on Exelon backfit appeal Thanks, Alex. I didn't know the specific time, but I'll pull it off Mike's calendar now that I do.

l'm guessing Mike will want to focus on the use of the backfit criteria and the error that is being cited. I gave him a copy of the draft in ADAMS, with lhe understanding that it will be updated more to address Bill's corrunents, so you can expect that he will be aware of the basics. He may also be interested in the public meeting held a while back, as well as the appeal process (if it happens).

I'll check with him on the details and get back with you if I hear anything different. Thanks!

Theresa, You are probably aware of a briefing with Mike Johnson that is scheduled for May 3 at 4:30pm to discuss the Braidwood/Byron backfit appeal. We are preparing to discuss an overview of our review of the backfit appeal and were wondering if you knew of any particular OEDO concerns or areas of interest that we should focus on.

Also, in case it might affect any questions that might arise during the briefing, I want to ensure you are aware that, should the licensee choose to further appeal the NRA Director's decision, that appeal would be directed to the EDO per Management Directive Handbook 8.4, section 111.A.S(h), section 111.A.6, and Exhibit 2.

Thanks for any information you might have. Please don't hesitate to let me know it you have any questions.

BYRON/BRAIDWOOD BACKFIT REVIEW PANEL BRIEFING FOR OEDO Key Messages

• Exelon appealed a compliance backfit imposed on Braidwood and Byron (B/B)

• Per NRA Office Instruction LIC-202, which implements the MD 8.4 backfitting process for NRA, a Backfit Review Panel was appointed by NRA Office Director to review the appeal

• The Panel determined that imposition of the backfit is necessary and application of the compliance backfit exception is appropriate, and recommended denial of the EGC's appeal

• In accordance with MD 8.4, the licensee can appeal the Panel's decision to the EDO

Background

• NRC approved 8/8 inadvertent ECCS operation (IOECCS) analysis in 2001 and 2004 SERs

• During review of 8/B MUR application in 2011, NRC identified that the licensee's UFSAR analyses for RCS mass addition events predicted water relief through pressurizer relief valves (PORVs) and/or safety valves (PSVs)

• RCS mass addition events are Condition II events per ANS-N18.2-1973 (incorporated into 8/B UFSAR). ANS-N18.2-1973 requires that Condition II events cannot generate more severe Condition Ill or IV events without another independent event occurring

• PORVs and PSVs were not qualified for water relief - the licensee relied on EPRI testing that does not demonstrate the PSVs and PORVs would re-seat and not leak following water discharge

• Failure of PORV or PSV to re-seat could result in a small break LOCA, a Condition Ill event

• NRG issued backfit via October 9, 2015 letter:

- UFSAR Sections 15.5. 1 (IOECCS), 15.5.2 (CVCS malfunction), and 15.6.1 (inadvertent opening of PORV or PSV) predict water relief through a valve not qualified for water relief

- UFSAR does not demonstrate compliance with ANS design requirement for Condition II events, thus, does not comply with GDCs 15, 21, and 29 and 50.34(b)

- Change in NRC position from 2001 and 2004 SER approvals

• Exelon appealed NRC's backfit to the NRA Office Director via December 8, 2015 letter:

- compliance backfit did not apply because NRG did not explain how its prior position was erroneous due to an omission or mistake of fact

- acknowledged consistent NRC position regarding propagation of Condition II events

- NRC application of GDCs differed from positions documented in 2001 and 2004 SEs

• NEI submitted comments in support of Exelon appeal by letter dated January 20, 2016 Backfit Review Panel

• Met with NRG staff involved in the backfit decision and with Exelon via public meeting

• Confirmed that UFSAR predicts water relief for RCS mass addition events

• Confirmed that PORVs and PSVs were not shown to re*seat following water relief, failure to re-seat could result in SLOCA,

• Staff appropriately identified that new position is a change from 2001 and 2004 approvals and appropriately identified the compliance exception as applicable

• Consistent NRC position regarding propagation of Condition II events was the known and established standard

• Backfit cited water qualification of the PORVs/PSVs as the mistake of fact that led to erroneous approvals in 2001 and 2004

• But for the mistake of fact that the PSVs were not actually shown to be water qualified, NRC would not have approved the applicable UFSAR analyses in 2001 and 2004

• Panel recommended to NRA Office Director that Exelon's appeal be denied.

RE: Braidwood/Byron Badcfit Appeal to EDO Date: Wednesday, June 08, 2016 6:53:00 AM Tim, Thanks for your repty1. I haven't got the complete picture on this because I haven't seen all the staffs work on the backfit and backfit appeal. However. my impression of Exelon's Backfit Appeal to the EDO is that they make a compelling case. As such it has also caused me to rethink my support for the RIS consistent with my previous expression to you that one of the reactions to the RIS could be "why is the NRC expending resources on this issue when it is not a safety concern.

Re: Braidwood/Byron Backfit /\ppeal to EDO I agree with Eric. Given an outstanding known appeal, we should coordinate with CRGR. No sense in issuing the RIS 011ly to find out subsequently that it did not hold up through the second appeal. The additional work and turmoil that situation would present, I am sure, we all would appreciate avoiding.

Jen - thanks for the info and insights. Do let me know if you or staff see this differently, l would certainly listen.
