Meeting Status: Accepted Organizer: Clark, Theresa Required Attendees: McGinty, Tim; DSSCAL Resource; Holahan, Gary; West, Steven; Scarbrough, Thomas; Spencer, Michael Hi Tim, Thanks for being willing to meet with the EOO' s appeal panel for the Exelon backfit. As we discussed on the phone, you can bring staff if you would like to. However, you may not feel the need at this point-we are intending for this to be a casual conversation about the technical issues that led to the backfit and aren' t sending any preparatory materials/questions. If we need further discussions (e.g., with particular staff) after this we can certainly do that. | |||
Also-I know this isn't a great time (and Steve has a potential conflict) bu t getting another time in the next two weeks was nigh on impossible. Let me know if it is really bad timing for you. Thanks! | |||

As discussed between Margie and Gary, the backf it appeal panel for the Byron/ Braidwood PSV/PORV backflt would like to discuss the initial backfit review process with Geary Mizuno. This looks like the only t ime in the near-term that will work for most. (Steve, I know you have a meeting but am hoping you might be able to reschedule or have Brian cover it.) | |||
I don't believe any prep/ questions/ materials are needed Oust a chat) but others on the panel can correct me. | |||

In the case of a safety valve, I believe that the failure to reclose could be considered a single failure if the NRC staff accepted the justification provided by the licensee that the valve will reliably reseat.

: Tim, Frank, Based on a review of more than 50 documents (covering a period from 1971 to the present), and discussions with OGC staff, NRR staff, former NRR staff. and the CRGR, the Exelon Backfit Panel has developed Preliminary findings that it believes should be shared with NRC internal stakeholders. | |||
Spencer, Michael | Here is the Exelon Backfit Panel's roll-out plan for completing its work: | ||
8/1/16 Provide Preliminary Findings to OEDO for information and feedback on scope and depth-of-review and other expectations 8/2/16 Provide Preliminary Findings to NRR (and former NRR staff) and OGC for completeness and accuracy | |||
.. ."fact checking" 8/9/16 Collect any comments 819/16 RES provides insights on risk and safety significance 8/19/ 16 Prepare Draft final Report with findings, response to questions, and recommendations. | |||
8/29/16 Provide final Report to EDO The Panel will be available for discussion of any issues or concerns during the weeks of 8/1/16 and 8/8/16. | |||

We talked about the 2000 version, but on further reflection, I think the 2015 version is the one to examine because the ANS standard is not a requirement and could only be a current applicable standard for Byron and Braidwood to the extent discussed in the latest FSAR. The existing or appropriateness of previous 50.59 changes is a separate matter. looking at the 2015 FSAR, I found no evidence in Chapter 1 (which has an incorporated by reference (IBR) section) or in Chapter 15 that the ANS standard is IBR'd. Even so, it is possible that somewhere in the 758 page Chapter 15. there is a statement along the lines of "Activity X is accomplished in accordance with the ANS standard," which would import the portions of the ANS standard applicable to Activity X. Still. the Backfit doesn't reference the ANBS standard directly, but instead references FSAR Section 15.5.1.3. | I looked at the 2015 UFSAR for Byron and Braidwood.

@nrc.g~>, "West , Steven~ < | The backfit and the two staff responses to the Panel's review confirm the need for additional backfitting guidance and training. | ||

- Rich, Following (and attached) is the information on the backfit appeal I am working on. I appreciate your commitment to support the panel's effort to better understand and characterize the safety and risk significance of the plant configuration. Gary Holahan or I will be in touch after we gather our thoughts and have a better idea about specific objectives and needs. As I mentioned to you. we will probably be looking for some transient analyses and risk assessments (using SPAR models).

- Steve, Tom,
- Michael, As you can see, the EDO has signed the Backfit Appeal Panel Charter. It calls for a final report and recommendation by August 29. 2016. Although t do not expect this task to require anyone's dedicated. full-time attention, I do plan to meet frequently, especially during the planning stage. I suggest meeting this afternoon (3 pm?) or on Monday and Wednesday next week. I suggest that we establishing a regular pattern of meetings for the following weeks. There will also be the need to schedule meetings/discussions with NRR staff and management, Exelon. perhaps NEI (which sent a supporting letter last week). other stakeholders. and perhaps CRGR.
I have identified more than 20 relevant documents (electronic copies of a few attached, including a list of all);
and I am having paper copies made. Copies should be available on Monday. The most immediately relevant documents are: the charter, the Exelon appeal letters of 12/8/15 (to NRR) and 6/2/16 (to EDO), and the staff letter of 5/3/16. I have identified numerous issues that I think we may need to pursue, but that can wait for our first meeting.
I will send scheduler requests to check your availability today and next week.
Thanks in advance for your support, Gary 3

- Steve, Tom,
- Michael, As you can see. the EDO has signed the Backfit Appeal Panel Charter. It calls for a final report and recommendation by August 29, 2016. Although I do not expect this task to require anyone*s dedicated, full-time attention, l do plan to meet frequently, especially during the planning stage. I suggest meeting this afternoon (3 pm?) or on Monday and Wednesday next week. I suggest that we establishing a regular pattern of meetings for the following weeks. There will also be the need to schedule meetings/discussions with NRR staff and managemen1, Exelon , perhaps NEI (which sent a supporting letter last week), other stakeholders, and perhaps CRGR.
I have identified more than 20 relevant documents {electronic copies of a few attached, including a list of all):
and I am having paper copies made. Copies should be available on Monday. The most immediately relevant documents are: the charter, the Exelon appeal letters of 12/8/ 15 (to NRR ) and 6/2/16 (to EDO), and the staff letter of 5/3/16. I have identified numerous issues that I think we may need to pursue, but that can wait for our first meeting.
I will send scheduler requests to check your availability today and next week.
Thanks in advance for your support.

- Rich, Following (and attached) is the information on the backfit appeal I am working on. I appreciate your commitment to support the panel's effort to better understand and characterize the safety and risk significance of the plant configuration. Gary Holahan or I will be in touch after we gather our thoughts and have a better idea about specific objectives and needs. As I mentioned to you, we will probably be looking for some transient analyses and risk assessments (using SPAR models).

RE: FYI* Backfit Panel Being Formed by OEDO Importance: High Ed, If you haven't heard, l also "volunteered" to serve on the backfit appeal panel. I did not weigh in on your question about the CRGR meeting with the staff pending the appeal panel's kickoff meeting. We met this afternoon.
The panel will also be reviewing the proposed revision to the RIS_ During our kickoff meeting, among other things, we discussed coordination of the paners review with CRGRs review. In the short time available, we did not decide on any specific course of action. but agree that it was worthy of further discussion. Before you change the CRGR's plans or cancel you meeting with the staff, I suggest you touch base with Gary and perhaps, if Gary agrees, come to one of our panel meetings to discuss with the entire appeal panel. One idea floated was that the appeal panel could take the CRGR's time slot with the staff.

As we discussed on the phone, you can bring staff if you would like to. However, you may not feel the need at this point-we are intending for this to be a casual conversation about the technical issues that led to the backfit and aren' t sending any preparatory materials/questions. If we need further discussions (e.g., with particular staff) after this we can certainly do that.
Also-I know this isn't a great time (and Steve has a potential conflict) bu t getting another time in the next two weeks was nigh on impossible. Let me know if it is really bad timing for you. Thanks!

RE: safety valves If the NRC staff accepts the justification provided by a licensee that a safety valve will not stick open, then the a stuck-open safety vafve would be counted as the single failure in the accident analysis. Therefore, the licensee would not be required to assume another failure (such as losing one ECCS train). This was the result of the staff position for the Byron/Braidwood Stretch Power Uprate that the safety valve would not stick open based on the EPRI test data.
In the back.fit decision, the staff is taking the position that a stuck-open safety valve can only be counted as the single failure if the valve is qualified per the ASME BPV Code (which would include liquid service certification). Otherwise, the safety valve is assumed to stick open as a consequential failure caused by water relief.
In answer to your question, the capability of a safety valve to reseat under liquid service needs to be justified by the licensee for a stuck-open safety valve to be counted as the single failure in the accident analysis.
Thanks.

RE: safety valves
- Gary, I used the phrase "could be considered a single failure" because the NRC staff made this finding (at least implicitly) as part of its review of the Byron/Braidwood Stretch Power Uprate. The staff at that time assumed that the safety valves would reseat with liquid service. Therefore, the staff would have considered the failure of a safety valve to reseat to be the single failure in an accident analysis.

RE: safety valves Thanks Tom. Very helpful.
One sentence confused me [3'd sentence of the last paragraph]:
"In the case of a safety valve, I believe that the failure to reclose could be considered a single fal1ure if the NRC staff accepted the justification provided by the licensee that the valve will reliably reseat."
I understand the rest of the paragraph and the "Therefore ... ", but the "could be considered a single failure" has me confused.

RE: safety valves
- Gary, I agree that the vendor and ASME documents do not provide specific discussion regarding the potential for safety valves to stick open. However, the design and qualification of a safety valve must include its ability to reliably reclose. For example. the Crosby Engineering Handbook includes specific references to reclosing and 2
A passive failure in a fluid system means a breach in the fluid pressure boundary or a mechanical failure which adversely affects a flow path. Examples include the failure of a simple check valve to move to its correct position when required, the leakage of fluid from failed components, such as pipes and valves--
particularly through a failed seal at a valve or pump--or line blockage. Motor-operated valves which have the source of power locked out are allowed to be treated as passive components.
In the study of passive failures it is current practice to assume fluid leakage owing to gross failure of a pump or valve seal during the long term cooling mode following a LOCA (24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or greater after the event) but not pipe breaks. No other passive failures are required to be assumed because it is judged that compounding of probabilities associated with other types of passive failures. following the pipe break associated with a LOCA, results in probabilities sufficiently small that they can be reasonably discounted without substantially affecting overall systems reliability.
It should be noted that components important to safety are designed to withstand hazardous events such as earthquakes. Nevertheless. in keeping with the defense in depth approach, the staff does consider the effects of certain passive failures (e.g., check valve failure. medium or high energy pipe failure, valve stem or bonnet failure) as potential accident initiating events.
Thus, the NRG staff allows check valves to be assumed to be passive components in certain instances under the Single Failure Criterion described in SECY-77-439.
With respect to squib valves, the NRC staff raised concerns during AP1000 vendor inspections regarding the potential for squib valves to open inadvertently. In response, Westinghouse has included blocking features to avoid inadvertent opening of squib valves. AP1000 DCD Tier 2, Section 15.6.1 includes inadvertent opening of Stage 1 ADS valves (MOVs), but not Stage 4 ADS valves (squib valves). Therefore, the inadvertent opening of the ADS squib valves would be an example where this potential would be considered a single failure.
In summary, the NRC staff allows some components to be assumed to be passive in evaluating single failures as described in SECY-77-439. I believe that the reference to "under development" in 10 CFR Part 50, Appendix A, allows the NRC staff to make a case*by-case decision for a single failure assumption for a passive fluid component, and whether a "known and established standard" can be considered to exist regarding the performance of that component. In the case of a safety valve, I believe that the failure to reclose could be considered a single failure if the NRC staff accepted the justification provided by the licensee that the valve will reliably reseat. The staff accepted the EPRI testing program for this justification for Byron and Braidwood during the Stretch Power Uprate review based on its evaluation of the EPRI test data without mandating that the safety valves be certified for liquid service by ASME and the National Board. Further, we have found a wide range of justification accepted by the NRC staff for the ~qualification" of safety and relief valves for liquid service in license amendments for other nuclear power plants. Therefore, I do not consider a specific "known and established standard" has been applied by the NRC staff in evaluating the acceptability of safety and relief valves to perform with liquid service. Nevertheless, I believe that licensees should avoid water relief through safety valves because they were not originally intended for this service, and the testing program performed by EPRI was limited in the sample size of valves tested and their range of service conditions.
Thanks.

reseating of its pressure relief valves. In addition, ASME Standard QME-1-2007 as accepted in RG 1.100 (Revision 3) defines a pressure relief assembly as follows:
pressure relief valve assembly: a valve assembly that is designed to open to prevent a rise of internal fluid pressure, in excess of a specified value, and re-close.
Mandatory Appendix I, "Qualification Specification for Active Valves," in ASME QME-1-2007 in Section OV-18000 states in item (h) that the specification must incfude blowdown (difference between set point pressure and reseating pressure).
Section QV-7660, "Functional Qualification," for safety and relief valves in ASME QME-1-2007 states that functional qualification for pressure relief valve assemblies shall be as delineated in ASME BPV Code, Section Ill, Subsections NB, NC, or ND 7000.
Subsection NB-7000 in ASME BPV Code (2007 Edition) addresses the reclosing of safety valves in various paragraphs. For example, item (k) in NB-7220. "Content of Report," in NB-7200, "Overpressure Protection Report," requires that the report shall include consideration of set pressure and blowdown limitations, taking into account opening pressure tolerances and overpressure of the pressure relief device. In addition, NB-7512.3, "Blowdown," for safety valve operating requirements specifies that the safety valves shall be adjusted to close after blowing down to a pressure not lower than 95% of the set pressure unless a different percentage is specified in the design specification and the basis is covered in the Overpressure Protection Report.
Therefore, the design and qualification of a safety valve include its ability to reclose reliably to be able to satisfy its blowdown requirements.
Until the TMl-2 accident, I do not believe that there was much concern regarding safety and relief valves sticking open. It was assumed that the simple spring-loaded design of safety valves provided reasonable assurance that this valve design was not subject to a significant concern regarding failure to reclose. In response to the TMl-2 accident. NUREG-0737 included Mqualification" requirements to provide confidence that safety and relief valves would not stick open under various steam and liquid conditions. However, NUREG~
0737 did not require that safety and relief valves be "certified'" for all service conditions. The EPRI testing program in response to NUREG-0737 was limited in its extent of testing. but did confirm that a generic problem did not exist regarding safety and relief valves sticking open under various conditions.
SRP Section 15.6.1 (2007), "Inadvertent Opening of a PWR Pressurizer Pressure Relief Valve or a BWR Pressure Relief Valve," provides a requirement to evaluate an inadvertent opening of a PWR safety valve. SRP 15.6.1 states that a pressure relief valve, as defined in ANSI 895.1-1972, is a device designed to reclose and prevent further fluid flow after normal conditions are restored. The SRP section does not provide details regarding the assumption for the safety valve to stick open. However, AP1000 OCO Tier 2, Section 15.6.1, states that the "inadvertent opening of a pressurizer safety valve can only be postulated due to a mechanical failure." The AP1000 accident analysis assumes that the safety valve remains open throughout the event.
Check valves are considered passive components in some instances (such as system design) and active components in other instances (such as the 1ST Program). NUREG-1482 (Revision 2) states in Section 4.1 that SECY-77-439, Single Failure Criterion," dakd August 17, 1977, which was referenced in several plants' licensing bases, discusses thc failure 0f a check \'alvc t0 1110\'e to its correct ()(lsition as a passive failure; however, this docs not c<1rrespond to the i.s.sue of "active** versus .. passive for the purpose of 1ST.
In Section 2, SECY-77-439 (ADA~S No. ML060260236) states the following:
D. Passive Failure in a Fluid System 3
This is your area ... but I did check the Byron and Braidwood UFSAR and the Crosby Engineering Handbook (both added to the References). Neither speaks to safety valve re-closure as a "protection function" or even as a requirement (for either liquid or stream relief). Safety valves are clearly designed to re-close {as opposed to rupture disks and other "non-rec/osure" devices), but the Code and designer requirements seem to be limited to set-points and capacities.
Could it be that "failure to close" for a simple spring-loaded safety valve to considered a "passive failure" like pipe ruptures (or a valve bonnet rupture)? ... and therefore not required or addressed in safety analyses? Are there other components or functions that we just don't address as potential single failures or consequential failures because they are considered so unlikely? Check valves?
The introduction says {in a footnote),
Single failures of passive components in electric systems should be assumed in designing against a single failure. The conditions under which a single failure of a passive component in a fluid svstem should be considered in designing the system against o single failure are under development.
Does "under development" sound like a "known and established standard of the Commission?"
Could the answer be related to definition of and practice on "consequential failures"? Is "not designed for" or "not certified to" the standard? Or is "not expected to function" or "not assured to function" or "not demonstrated to" the standard? Or is there no standard?
Maybe the Panel shouldn't need to be working on such fundamental issues, but there doesn't seem to be an answers for such questions ...

Perhaps we could replace the sentence in the first paragraph with a sentence based on your addition, something like: ~The panel concludes that in 2001, 2004, and at present, the known and established standard of the Commission is that the probability of failure of pressurizer safety valves (PSVs) following water

Things to review
- Steve, Tom,
- Michael, Theresa, I have taken the Preliminary Findings document and incorporated it into a "Discusslon" section. I added text to make it read like a report (no changes to findings or conclusions). Please review at Reports/ Backfit Appeal Report 2016 08 03 2pm.
Next I will start on the Enclosures (and the sections referring to them).
I have also drafted (first draft. .. ) a memo to Vic presenting the report. Please review at Reports / Cover memo Backfit Appeal Panel 2016 08 03 2pm.

The conclusion is that the maximum benefit from a potential backfit remedy would provide a very small reduction in risk (i.e., less than 1E-06/year). It should be noted that the analysis contained in the report was narrowly focused on the backfit question under review by the Appeal Review Board and is intended to provide additional context and insights to the Board.

RE: Containment Contamination Argument Search of FSAR stuff. .. see red for most interesting. Sorry this is sort of stream of consciousness at the moment.
Re standard conformance:
Braidwood 2004 FSAR submittal, but most pages dated December 2002: ML051660219
- P. 15.5-3, Section 15.5.1.2 on IOECCS: "American Nuclear Society standard 51.1/Nl8.2-1973 (Reference 2) describes example 15 of a condition II event as a "minor reactor coolant system leak which would not prevent orderly reactor shutdown and cooldown assuming makeup is provided by normal makeup systems only." In Reference 2, normal makeup systems are defined as those systems normally used to maintain reactor coolant inventory under respective conditions of startup, hot standby, power operation, or cooldown, using onsite power. Since the cause of the water relief is the ECCS flow, the magnitude of the leak will be less than or equivalent to that of the ECCS (i.e., operation of the ECCS maintains RCS inventory during the postulated event and establishes the magnitude of the subject leak). Therefore, the above example of a Condition II event is met."
- P. Al.77-1 (dated December 1992): N18.2 is mentioned in a discussion of RG 1.77 and control rod ejection accidents (that they are a faulted condition as defined in N18.2 ).
- P. 15.0-13, Section 15.0.8 on plant systems and components for accident mitigation: "In determining which systems are necessary to mitigate t he effects of these postulated events, the classification system of ANS1-N18.2-1973 is utilized."
- P. 15.4-13, Section 15.4.3.l on RCCA misoperation: "Thus, consistent with the philosophy and format of ANSI N18.2, the event is classified as a Condit ion Ill event. By definition "Condition 111 occurrences include incidents, any one of which may occur during the lifetime of a particular plant," and "shall not cause more than a small fraction of fuel elements in the reactor to be damaged ... ""
Braidwood 2000 FSAR is only on CD in the File Center. so I can go get it.
Re 50.59s:
Braidwood 2002 50.59 report (ML023610638) - publicly available
- Part 1 of 2, p.129* 130 of PDF, effective date 7/11/00: UFSAR change package #DRP 8-190 to the Byron/Braidwood UFSAR revised the description in Chapter 15, Section 15.5.1 "Inadvertent Operation of Emergency Core Cooling System During Power Operations" to remove statements that operator action will be taken to manually open the Pressurizer Power Operated Relief Valves (PORVs). The transient description will be revised to indicate that if the Pressurizer PORVs are not available, the Pressurizer Safety Relief Valves ( PS RVs) will lift to relieve pressure initially releasing steam followed by subcooJed water. The existing discussion of the Pressurizer Overfill case will be deleted.
- Part 2 of 2, p.105-106 of PDF, dated 2002: UFSAR Change Package #DRP 9-075 revises the evaluation methodology for the Loss Of Offsite Power (LOOP) event (UFSAR Section 15.2.6) to incorporate water relief through the Pressurizer Safety Valves. This DRP is applicable to Byron and Braidwood Stations Units 1 and 2 ....
An additional evaluation was performed that concluded the Safety Valves will not be damaged by the water relief (Westinghouse letter LTR-SEE-01-287) .... This activity is not considered a departure from a method of evaluation described in the UFSAR because the new methodology (Water relief through the Pressurizer Safety Valves) has been approved by the NRC for a similar event for Byron and Braidwood Stations as part of the Power Uprate Safety Evaluation Report.
Parallel Byron 2003 50.59 report (ML031631016) -publicly available
- p.120-121, effective date 12/22/00: This purpose of this UFSAR change was to revise the description in Chapter 15 Section 15.5.1, "Inadvertent Operation of Emergency Core Cooling System During Power Operations", to remove statements that operator action will be taken to manually open the pressurizer power operated relief valves (PORVs). The transient description is revised to indicate that if the pressurizer PORVs are not available to open to relieve pressure then the pressurizer safety relief valves {PSRVs) will lift to relieve pressure initially releasing steam followed by subcooled water to mitigate the pressurizer overfill portion of the transient. The effect of the proposed activity will be an updated licensing basis and an updated operations procedure that will reflect the updated licensing basis .... Utilizing the relief valves may result in some degradation and the possibility that the valves may not fully reseat. The probability of the relief valves failing open due to water service application was previously evaluated in the SER for NUREG-073 7, Item 11.D. l. Thus, the change is bounded by the previously evaluated SER and does not increase the probability of occurrence or the consequences of an accident or a malfunction of equipment important to safety .... For analysis purposes, the PORVs are assumed to not be available for mitigation of the inadvertent operation of ECCS during power operation accident. However, current Technical Specifications requires that "Each PORV and associated block valve shall be OPERABLE" during Modes 1, 2, and 3 (LCD 3.4.11)."
- p.136-137, effective date 7/ 11/00: same topic as 1§! Braidwood item
- p.161-162, dated in 2002: same topic as 2"d Braidwood item My earlier notes from 50.59s on microfiche- I can go print - these were from the timeframe when PORVs were going to be credited.
- 3/18/94 - (78728:302) change M6-1/2-88-003 - safety-related power to safety-related relays for PORVs to enable manual control during a loss of offsite power
- 3/31/97 (92355:157) - draft revision package 6-013 - reanalysis of IOECCS, conservative analysis of overfill scenario, remains isolable when ECCS terminated, PORVs allow relief and prevent pressurizer from filling ( 1 PORV adequate); DNB limits met; water through safeties precluded by relief through PORVs
- 3/31/99 - (A7530:247) change GG-98-0167 - changes to TRM Section 3.4 on Reactor Coolant Systems, justification for automatic PORV actuation to mitigate pressurizer overfill during spurious SI at power Other documents I came across:
- 2004 version ofTechnical Requirements Manual (similar format to TS but not part of license) has TLCO 3.4.d saying one PORV must be unisolated and capable of responding in automatic, or the plant must shut down in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. (ML051660238, p.151 of PDF)- Same in 2014 submittal (ML14363A504)
- 2004 version of TS bases talks about PO RVs and PSVs in the discussion of pressurizer pressure limits (ML051660226, p.35-36), then says this on p.181: HThe Pressurizer Water level-High trip Function provides a backup signal for the Pressurizer Pressure-High trlp and also provides protection against water relief through the pressurizer safety valves. These valves are designed to pass steam in order to achieve their design energy removal rate. A reactor trip is actuated prior to the pressurizer becoming water solid." The pressurizer and PSV/PORV specific items start on p .385 of the PDF.

Subject:
Containment Contamination Argument
- All, Section 3.1.2.2 of the 2015 Backfit states:
The licensee has not addressed the questions of how long it would take to clean up a contaminated containment, and whether the time required for completing the cleanup effort and repairing or replacing any damaged PSVs could be long enough to delay the plant's return to operation beyond the short period that is implied in the UFSAR, Chapter 15.5.1.3, definition of Condition II events.
Therefore, the "short period" standard is "implied" in UFSAR Section 15.5.1.3. The Backfit doesn't mention any specific revision of the UFSAR, so I assume it is the current one. This makes sense because it is the current FSAR revision that is currently applicable to the licensee. The Backflt doesn't raise the issue of an inappropriate 50.59 change, and if there were such an inappropriate change, this would be an enforcement matter. not a backfit matter. Therefore. although we discussed the 2000 FSAR, I looked at the 2015 FSAR.
I looked at the 2015 UFSAR for Byron and Braidwood. We talked about the 2000 version, but on further reflection, I think the 2015 version is the one to examine because the ANS standard is not a requirement and could only be a current applicable standard for Byron and Braidwood to the extent discussed in the latest FSAR. The existing or appropriateness of previous 50.59 changes is a separate matter.
looking at the 2015 FSAR, I found no evidence in Chapter 1 (which has an incorporated by reference (IBR) section) or in Chapter 15 that the ANS standard is IBR'd. Even so, it is possible that somewhere in the 758 page Chapter 15. there is a statement along the lines of "Activity X is accomplished in accordance with the ANS standard," which would import the portions of the ANS standard applicable to Activity X. Still. the Backfit doesn't reference the ANBS standard directly, but instead references FSAR Section 15.5.1.3. That FSAR section in its entirety is as follows:
15.5.1.3 Radiological Consequences There are only minimal radiological consequences associated with inadvertent ECCS operation. The reactor trip causes a turbine trip and heat is removed from the secondary system through the steam generator power relief valves or safety valves. Since no fuel damage is postulated to occur for this transient. the radiological consequences associated with an atmospheric steam release from this event would be less severe than the steamline break event analyzed in Subsection 15.1.5.3.
Water relief from the pressurizer PORVs and safeties may result in overpressurization of the pressurizer relief tank (PRT), breaching the rupture disk and spilling contaminated fluid into containment. The radiological releases (offsite doses) resulting from breaking the PRT rupture disk are limited by isolation of the containment.
Maybe engineers can read more into this than I can, but I see nothing implied here that implies a short period for the plant's return to operation.

We'll do formal concurrence and signature next week.
These versions include everyone' s edits/comments. combined with my editing. The most significant cha nges I made were some restructuring in 3.12 (former 2.12) and the addition of a new short section 2 per Steve's suggestion. I didn't track them because the tracking was getting out of hand, and at this point we might do best to do a clean read anyway.

Thanks Theresa. J've been reviewing Friday's version. About 80 percent completed. I have some corrections and editorial suggestions. I expect to be done by COB today. I think I'll also have a recommended addition to the memo re RIS 2005*29 and it's revision. I'll send to all when completed.
Did we decide that we don't need to address why the previous appeal review panel got this wrong?
From the UWC and NSIAC meetings last week, there is heightened industry interest in where we are going to come out on this. We should plan on our report being made publicly available.

REVIEW: informal concurrence version of panel report Hi all-attached are the cover memo (no change since the last version, I think) and report (both clean and with changes tracked to the last version I sent - not since the beginning). I incorporated the edits that Michael sent Friday.
I recommend that you guys read these and send any remaining edit s/comments by mid-day Tuesday-consider this informal concurrence. Then 1can give another look before we have the meeting with Vic. Shortly thereafter I assume w e would be able to sign an official copy. (Somewhere in t here I w ill ask Patti to make a concurrence package.)
Thanks!

Comments on NRR appeal review
- Theresa, This version includes the changes I added to try to address my comment about the NRR appeal review. These changes are on pages 2 through 5. What I don't know is if the NRR review panel's report is publically available or not. If not, we may not want to mention it in this report as I suggested. And, if we don't mention it, we would need to revise some of my language to only refer to the letter back to the licensee.

! and not available. Please proceed without me. I remain comfortable with our review, our conclusions and our recommendations. A few thoughts:
A surprisingly weak and uninspired defense of the backfit. An equally humdrum critique of the Panel's review and conclusions.
It may be better for Michael to address this, but it seems to me that one need find only one fatal flaw with the backfit to overturn it. The staffs argument that it considered numerous issues (as did the Panel) doesn't diminish the Panel's findings.
The staff and the panel seem to agree that not everything (guidance, interpretations, safety evaluations, etc.) has been clearly and consistently established and documented over time. We seem to differ on how new interpretations should be promulgated.
The backfit and the two staff responses to the Panel's review confirm the need for additional backfitting guidance and training.
Steve
