The PWROG had not taken any actions to date and does not have a recommended schedule i for action on the Part 21 s, but will be having ~ phone call 5/1 9 o initiate. the .9-rocess to address _J this concern as an "emergent issue".

Flowserve believes operating experience is consstent with the failure analysis supporting their previous Part 21 and does not plan to take any further action .

The BWROG performed a survey of their members in support of the Revision 2 update to BWROG-TP-13-006. This survey identified the following:

• Duke has disassembled more than 23 valves and found that the stem-disc connection was not torqued to the required preload, but that no wedge pins or stem threads were damaged.

• Diablo Canyon is inspecting valves within the Part 21 scope during an ongoing outage and have found two valves with anomalous indications. Both of these valves will be disassembled and inspected.

NRC is questioning whether the use of the MOV diagnostic testing (i.e., stem strain trace measurements) and the stem rotation deflection check reliably demonstrate that wedge pins

remain intact, that prior over-torqueing did not occur, or that stem/wedge thread degradation / Comment tMDI: Did this happen? A.ny has not already occurred. / ' results?

03.09 Reasonable Expectation: The dlscovery of a degraded or nonconforming condition may call the operability of one or more SSCs into question. A subsequent determination of operability should be based on the licensee"s "reasonable expectation," from the evidence collected, that the SSCs are operable and that the operability determination will support that expectation. Reasonable expectation does not mean absolute assurance that the SSCs are

operable. The SSCs mqy be considered operable when there is evidence that the possibility of failure of an SSC has increased, but not to the point of eroding confidence in the reasonable expectation that the SSC remains operable. The supporting basis for the reasonable expectation of SSC operability should provide a high degree of confidence that the SSCs remain operable. It should be noted that the standard ot "reasonable expectation" is a high standard, and that there is no such thing as an indeterminate state of operability; an SSC is either operable or inoperable.

RE: LaSalle Hi Mark-Just had my biweekly meeting with Brian McDermott and one question he had was if the licensee's stem-disc margin analysis considered the friction needed to move the stem collar (e.g., under the presumption that the stem collar offers some resistance to vertical movement of the stem, does this impact the available margin?). 1think the answer to question 1 below covers the wedge pin question (i.e., shearing both ends of the wedge pin is considered) , but I wasn't sure if the collar was also factored in. Any insights you have are very much appreciated !

Subject:

RE: LaSal le For your awareness, 1consolidated the questions from this email string and provided some concise answers. Please Iet me know if you have any questions.

1. Did the NRC or licensee wedge pin shear analysis account for the two diameters of the wedge pin (both ends must shear simultaneously) and the force necessary to move the collar up the stem (must occur for even a hand tight stem to further rotate into the wedge on a closing stroke)?

a. The analysis does account for the two. The formula in the BWROG for the pin analysis is written the same way as well.

2. Has the licensee or vendor concluded that the valve in question has a press fit collar vs. the integral collar?

a. Press fit collar.

3. Have we learned anything from the plants (diablo and one other I believe) currently in outages that are looking at similar valves.

a. Columbia (similar design as LaSalle) entered into their outage last Friday.

No update yet of expected tlme to inspect the HPCS valve at the site.

b. Diablo Canyon identified two MOVs with abnormalities in their diagnostic traces.

i. SI injection to loop hot leg 8" valve failed to fully open during MOV diagnostic testing. The site inspected the valve, noted no disc stem separation and the wedge pin was intact; however, the licensee noteci "slight movement between the disc and stem" and "minor galling to the threads. " The reason for the abnormality in the trace has not yet been determined.

ii. RHR pump suction valve also had abnormalities during diagnostic testing.

lnspection scheduled for tonight (5/24).

4. How does the team reconcile the fact that the unit 1 valve had its stem replaced and thus does not have the same service life as the Unit 2 valve?

a. The licensee is currently estimating that the difference in total strokes between Unit 1 and the failed Unit 2 valve is approximately 20 strokes (this is based on a difference in number of outages between Unit 1 and Unit 2 and discussions with former test engineers from preoperational testing). The team's position is that, based on the wedge pin analysis, the forces being exerted on the pin on the Unit 1 valve is sufficient to shear the pin at any given stroke (i.e., not just during design basis accident conditions, but during any normai stroke); theretore. the difference in number of strokes is insignificant to the weak link analysis.

5. How does the Unit 1 HPCS valve breakout from others in industry that have a lot of run time and very few failures.

a.

(b)(5) Deliberative Privilege

6. ls this repa,rable on11ne*t

a. The licensee would have to shutdown (MODE 4) in order to inspect and repair the valve.

Additionally, some other aspects that you may want to consider:

1. The wedge pin analysis performed by the licensee used an inconsistent equation to compute margin to failure. Using the same data and the appropriate equation, the SIT calculates that the Unit 1 HPCS injection valve currently has negative margin (i.e., -27%) when using the same data. Therefore , the pinis susceptible to shear every time the valve is closed. This was discussed with LaSalle this morning and they are currently trying to justify their use of a different equation.

2. Stem rotation checks and the MOV diagnostic data have not been demonstrated to identify whether stem degradation has occurred or will occur. l.e. the Urnt 2 HPCS injection valve that failed showed minimum stem deflection through all stem rotation checks performed and exhibited no trace abnormality that could be correlated to stem degradation.

3. The licensee could not successfully benchmark the methodology used for operability. l.e., using the operability bases described in the opeval, the Unit 2 HPCS valve that failed would have been declared operable with positive margin.

stem rotation check?

With the wedge pin sheared, interferences between the broken pin fragments/debris and adjacent threads can cause damage and interferences between the rnating threads, while also limiting rotation. The interferences may be sufficient to bind the joint during subse uent strokes, preventing detection of a loosened or degraded connection .

Page 9 of 60 of the failure analysis.

Explains why stem rotation check might have showed minimal rotation just prior to the failure.

Bria n Benn ey Communication Plan - Anchor/Darling Valve Failures (Last Updated June 8, 2017) lssue to be Communicated On February 11 , 2017, a valve failure (stem disk separation) occurred at LaSalle Unit 2 to an Anchor Darling Double Disk gate valve . The plant specific implications of this issue are being addressed through a special inspection team . Due to the fact that this type of valve is widely used in the nuclear industry, the generic implications of this failure merit investigation. This investigation is ongoing. This plan addresses only the generic aspects of the valve failure.

Plant specific issues will be addressed by Region 111.

Stakeholders may be interested in:

The fc1cts associated with the failure, including cause The extent of use of the valves in the industry The generic safety sign ificance of the failure to the industry Actions proposed by industry/NRC staff asa result of the generic investigation Communication Team Region 111, NRR (DPR, DE, DIRS), NRO (DCIP), OPA Communication Methods to be Employed

1. This plan and accompanying information will be provided to ali members of the communication team

2. An lnformation Notice will be issued. The projected issue date is 16 June 2017

3. A category 2 public meeting will be held at NRC Headquarters. The date of the public meeting is still pending but could be as early as 19 June 2017

4. NRC staff is in direct communication with the licensee and affected industry groups to obtain the necessary facts to support the lnformation Notice and the public meeting Key Messages to be Communicated The NRC staff has significant interest in this issue but has no immediate safety concerns with respect to plant operations due in part to the relatively sparse operating experience, the low risk associated with failure , and the redundancy associated with even the most safety critical valves.

The valves under consideration are widely used in the industry.

There have been two known failures of these valves , one each at Browns Ferry in 2012 and LaSalle this year. due to this failure mechanism. There have been a few additional failures which may be due to related causes.

The safety significance of these valves to the operation of the plant varies from plant to plant based on where in the plant the valves are installed.

The NRC staff has significant interest in this issue but has no immediate safety concerns with respect to plant operations due in part to the relatively sparse operating experience, the low risk associated with failure, and the redundancy associated with even the most safety critical valves.

The NRC is currently investigating both plant specific and generic implications of the valve failures and will continue to update information concerning this failure as it becomes available.

Supporting Facts/Analysis The present inquiry involves Anchor Darling double disk gate valves with threaded and pinned connections between the stem and the upper wedge, and non-integral (shrink fit) collars, where the valve actuator has sufficient power to shear the wedge pin (torque load) and/or move the collar (axial and torque loads) (See figure below)

VERTICAL STEM It BACKSEAT (STEM CENTERUNE)

STEM STEM THREADS BODY HORIZONTAL

't (PORT CfNTERLINE)

WEDGE SPRING The design philosophy for valves configured as described above was that the wedge should be torqued against a rigid collar with sufficient force to resist alt applied loads. All loads would ,

therefore, be carried by the threads and interaction forces between the wedge and the collar.

The pin serves as a non load bearing component to preclude unthreading of the stem/wedge due to, for example, vibration .

Current testing and analyses for valves configured as described above is that the resistance of the collar to motion along the stem is less than the force applied by the actuator. This results in the collar slipping up the stem and the loss of any pretorque and other interactive forces between the wedge and the collar. Upon loss of these forces, the torque from the actuator is applied directly to the wedge pin. The wedge pin was not designed to be load bearing and may fail in shear.

There have been two valve failures due to the above scenario; Browns Ferry in November 8, 2012, and the current failu re at LaSalle. ln each case the pin sheared, the threads were damaged sufficiently to limit rotation of the stem in the disk. ln the Browns Ferry case the ultimate failure of the valve was a loose part that prevented the disks from seating resulting in excessive leakage; the wedge and stem did not separate. Thread damage was so severe that the wedge could not be unthreaded from the stem and had to be cut free. ln the LaSalle case, the collar was pushed up, thereby causing a loss of torque, then the load was transmitted to the wedge pin, which caused the pin to shear. The shearing of the pin caused some damage to the threads which restricted but did not fully eliminate rotation of the stem in the wedge . Over time, relative motion of the stem and wedge caused sufficient damage to permit stem disk separation.

The key elements to these failures are collar motion, transfer of loads to the wedge pin, shearing of the wedge pin with resultant thread damage, and at a much later time (based on oxidation of the wedge pin ends) failure of the valve.

Following the Browns Ferry failure, the manufacturer issued apart 21 on the event. The manufacturer proposed that the failures were due to inadequate torqueing and that the issue could be resolved by retorqueing the stem and wedge. Following the failure analysis of the LaSalle valve, the manufacturer has indicated that they will review the accuracy of the part 21.

The NRC staff presumes that this review is to assess the motion of the collar and its effect on the previously proposed solution.

Questions and Answers Q1 What are the facts associated with the failure, including cause?

A1 See facts above Q2 Are these valves extensively used in the industry?

A2 Yes, see the Flowserve Part 21 dated Feb 25, 2013, ADAMS No. ML13064A012 Q3 What is the generic safety significance of the failure to the industry?

A3 Based on a8 very conservative model.1-wl=i-iG-A- assumi!J.ges that ali valves are of the type under consideration and have the potential to fail, finds an insignificant qeneric~e change in risk to the plant as compared to the "normai,, scenario is insignificant._The plant-specific safety significance of this failure is 13lant speei.fic as ea~laR-t may have this type-efvaries depending on where valves of this type are used in different systems with different safety significances.

Based on a very conservative modei which assumes that all valves are of the type under consideration and have the potential to fail , the change in risk to the plant as compared to the

"normai" scenario is insignificant. Additionally, the failure of even the most risk significant of these valves can be tolerated due to the presence of backup and alternate systems 04 Actions proposed by industry/NRC staff asa result of the generic investigation A4 The NRC staff's investigation is ongoing. Courses of action will be developed either during or following the investigation, as appropriate.

Bill -

Hope your ttip is going well. I think a key aspect the SIT has been focusing on is the integrity of the stem-disc wedge pin. The concern is that the BWROG testing guidance cannot determ.ine if the wedge pin is still intact (though it may be able to detect if there is gross movemeut of tbe stem disc connection). So, if there is conceru that the wedge pin has been sheared due overtorquing by the motor actuator, the testing will not be able to detenniue if the pin is intact or if the stem/disc connection has been damaged . However, shearing of the pin does not necessarily Jead to stem-disc separation, but it Jeaves the valve in an indetenniuate state without auy design feature to prevent stem-disc separation . During the May 16 call, the BWROG noted that the most recent rev of the guidance included additional requirements to trend stem rotation checks over time, but this was viewed as a compensatory measure (so the revision also noted that the long term solution for high prio1ity valves was disassembly and inspection unless an analysis could demonstrate that the valve was not overtorqued in the past). The guidance to inspect bigh priority valves is in better alignment with the Flowserve Pa1t 21 which reconunended dissassembly/retorquing in order to resolve tbe issue.

I'll get with Ken O'Brien aud cla.rify where the team is at with the BWROG guidance relative to any performance deficiency they may identify. Also haven't gota fin al read from our staff on the adequacy of the newer BWROG guidance but will check with Mike Farnan to see where we're at.

Safe travels back bome!

• NRR/DPR continuing preparations for a public meeting to discuss the industry response to the Flowserve Part 21 and recent operating experience. Meeting will be coordinated with owners groups, Flowserve, and NEI and will assist the staff in assessing the need for further regulatory action following issuance of the lnformation Notice. The objective of this meeting will be to solicit input from industry on recent actions taken with regard to the Flowserve Part 21 in light of LaSalle valve failure. This information will be used to inform the LIC-504 decision-making process ..

Purpose:

Continue discussion of LIC-504 process to address generic impllcations arising from LaSalle special inspection. Where appropriate, make decisions on the following:

• Continue to refine potential decision options Schedule for completing IN ldentify subsequent follow-up activities (e.g., additional generic communications, inspection activities)

• Discuss planning for Follow-up Public Meeting This is the seventh meeting held on the LaSalle LIC-504 issue - previous meetings were held on May 3, May 5, May 10, May 11 , May 18, and May 24. Agenda is attached.

Status Reports:

• LaSalle Special lnspection (M . Jeffers, Region 111) The Special lnspection Team (SIT) still has operability concerns for the Unit 1 HPCS injection valve after reviewing the licensee's revised operability evaluation. ln general, the methods used by the licensee to demonstrate operability of the susceptible Anchor Darling Double Disc Gate Valves are not able to predict failure when benchmarked to the Unit 2 HPCS injection valve. However, the licensee has been able to provide sufficient information to preclude the SIT from proving beyond a reasonable Ievel of confidence that the Unit 1 HPCS injection valve is inoperable.

ln particular, there is uncertainty associated with certain analysis parameters, such as the stem coefficient of friction, that support the licensee's operability determination. Therefore, The licensees has received the completed failure analysis for the Unit 2 HPCS injection valve. This was provided to HQ staff for informat...io_n_. - - - - - - - .

The SIT plans to exit either on Friday or ea[ly next week. (b)(5) Deli beratve Privilege (b)(5) Deliberative Privilege Exelon plans to senci in a letter identifying compensatory measures to mitigate potential failure of the Unit 1 HPCS injection valve (e.g., guarding systems such as RHR and ADS), committing to inspecting the Unit 1 HPCS valve during the next Mode 4 entry, and inspecting other susceptible valves identified by the team.

The SIT's perception is that the BWROG guidance is not effective at establishing operability of A/D valves in light of the Flowserve Part 21 issue The SIT believes that the Flowserve Part 21 adequately captures the failure mode and provides adequate guidance to disassemble, inspect and retorque the valves.

• lnteractions with PWROG/BWROG (B. Benney, L. Watkins, NRR/DPR) - No new information

• lnteractlons with NEI (G. Bowman, NRR/DPR) - DPR has contacted NEI in order to identify a point of contact for the valve issue. Once a POC is identified, DPR will set up a preliminary phone call to provide NEI with basie information related to the Flowserve Part 21 and related valve issues and being coordination for a follow-on public meeting. Aegion 3 would like to be included in call.

• Risk Assessment (J. Circle, NRR/DRA) - DRA provided additional background on the pretim army risk assessment conducted for this issue. A total of 11 plants were evaluated -

2 with known locations of Anchor/Darling double disc gate valves, and 9 that represented a spectrum of BWR/PWR plant designs. To represent the degraded state of the Anchor Darling valves, the base MOV failure probability was multiplied by a factor of 5.9 ar 10.9 (to represent a 50 ar 100 fold increase in the mechanical failu re probability of the valve, assumed to be 10% of the total base failure probability). This resulted in an increase in CDF considered to be "small" per AG 1.174 guidelines. DRA committed to document the method and results obtained from their study. The risk results were also plotted against the AG 1.174 acceptance guidelines (see below - results for 10.9 multiplier for base MOV probability of failu re).

The IN is written at a high Ievel and provides an overview of recent operating experience (LaSalle, Browns Ferry, Surry, River Bend)

Schedule for Public Meeting - NRR/DPR (L. Watkins) discussed the planning goals for public meeting with industry to discuss recent actions taken to address anchor darling valve failures. Th is meeting will be used to gather information to support the NRC's LIC-504 process. DPR is proposed scheduling the public meeting during the week of June 19 (preferably 6/20 or 6/22). DPR will also coordinate with industry stakeholders (NEI, PWROG, and BWROG) to ensure that they will have sufficient time to present their recent activities at the meeting. DPR will develop a draft agenda for the meeting (e.g., NRC overview, followed by PWROG/BWROG/NEI perspectives and open discussion).

Further Follow-up Activities - Potential follow-up activities were briefly discussed, but it was concluded that insights from the public meeting would be needed to further refine the LIC-504 decision options.

• Communication Plan (B. Benney, NRR/.DPR)- DPR has developed a draft communications plan and will circulate among key team members to refine Q&A's and key messages. Goal is to have the comm plan available on the team SharePoint site by the end of the week to enable further review and comment.

• Next Meeting (K. Coyne, NRR/DE) - ln light of recent progress and need to focus on the development and issuance of the IN, the schedule for the next meeting was discussed. It was decided to schedule the next meeting for the week of June 12. This will allow a review of progress toward issuance of the IN and planning for the public meeting. A follow-up LIC-504 meeting will be scheduled for team alignment just prior to the public meeting.

Next Meeting: the next LIC-504 meeting will be scheduled for the week of 6/12.

Action ltems:

ALL

• Provide potential questions for Flowserve to NRO/DCIP (John Burke) for possible inclusion in the Flowserve vendor inspection plan.

lf you are off today, and don't get this email until Monday morning, just plan on working from the site Tuesday through Thursday.

Home stretch. We are developing our position paper one last time with all of the new information.

lf you haven't heard, Columbia's HPCS injection valve had a broken pin when they disassembled it this week. More to come. The LaSalle licensee was sending people out to Columbia to both help them and to get a first hand understanding of the Op Ex.

He a great and reasonably safe weekend.

As an aside, 1 feel like we are in a mode of NRC management having to cha llenge the staff's conclu sions rega rding operability. 1 believe we need the staff to focus on the licensee 's OD and chal lenging their assessment, assumptions, etc. .. Performing the OD is t he obligation of the licensee.

lf they are not doi ng it well, then we shou ld put the facts on the licensee's plate and senci them back to redo the OD. Mike F is a great asset, he has lat of first hand experience and knowledge. His time asa regu lator has been relatively short and he has been on the licensing end of things, not the inspection side.

RE: HPCS anchor darling va lve at Co lumb ia lmportance: High AII:

lnformation on the condition of the first of 3 Anchor-Darling (A-0) valves in the CGS HPCS system only developed in the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Here is a thumbnail bullets of what the CGS Residents currently know about HPCS-V-4 (HPCS injection valve):

1. HPCS valve (V-4) traces consistent over life of valve (no anomalous traces)

2. No stem rotation observed prior to auto start of H PCS on 5/25/2017

a. On 5/25, due to an apparent l&C error during a maintenance activity, HPCS auto-started

3. Diagnostic after auto start on 5/25/17 and prior to disassembly 6/1/2017 showed > 10 degrees rotation and open stroke failed trace

a. The BWROG acceptance criteria for stem rotation is <!= 5 degrees rotation

4. Stem was connected to upper wedge with minor displacement from full insertion (threaded)

5. Stem rotated freely by hand

6. Wedge pin sheared but still in the wedge

7. No FME in valve body

8. Collar minor displacement from stem (mils)

a. This is different than LaSalle who saw significant collar displacement

9. Actuator tripped on thermals after auto start on 5/25/2017

10. Magnesium rotor inspection - satisfactory 11 . Gear actuator possible gear damage awaiting inspection

12. Traces, photos, video, and corrective actions for repair underway (same for V-12, and V-15)

a. V-12 is the HPCS min-flow valve and V-15 is the HPCS suction transfer valve

b. Work on V-12 and V-15 disassembly and inspection over this weekend.

More to come as the CGS Residents get additional information as the licensee

inspections continue. Of note - Greg and Lindsay have and continue do a great job following this, and other ongoing outage issues.

Re: LaSalle Failu re Evaluation Report for LaSalle 2E22- F004 Stem-to-Wedge Failu re Karla:

Thanks for all of the information on LaSalle you sent this afternoon.

I understand you talked to the CGS SRJ, Kulcum, and got the preliminary info on V-4 HPCS Injection. Unfortunately given the recent operational history for V -4 and the inadvertent HPCS autostart on 5/25, it's unclear to me if this valve may be representative of the entire CGS population of A-D valves. CGS is opening up the other two valves this weekend (HPCS min flow and HPCS suction swap) so we likely will have more Ext of Condition info nexl week.

For your info, R1V has designated a DRP and DRS POC for ali things A-D and we continue to feed all of the info to them. Chris Speer (RI at Waterford) and Chad Stott (EB 1 inspector) should continue to have the best snapshot of complete info we have in RIV as it comes in.

Finally, for you info and to update yow* distribution lists, Jeremy Groom and Mark Haire recently swapped BC slots such that Mark is now my Chief with oversighl of CGS, Diablo, and Comanche; Jeremy is now the PSBl (security) chief.

Have a great weekend.

Solicitation of Comments 6/6: Draft IN on anchor/darling double disc gate valve (TAC MF9698}

The NRR Generic Communications Branch has been working with the NRR/DIRS Operating Experience Branch to develop the attached/linked draft lnformation Notice (IN) discussing operating experience associated with anchor/darling double disc gate valve wedge pin shearing and will promptly begin the formai concurrence process. Since these valves are used widely in various diverse safety systems (HPCI, HPCS, RHR, RCS, etc),

the NRC staff is working towards issuing this high priority IN within 2 weeks.

The Regions will be part of the formai concurrence chain for this document and concurrence will be requested in the next couple of days from one of your Division Directors (DRP or DRS). You are receiving this e-mail to have an opportunity to review the draft IN and provide comments prior to the formai concurrence process. Time spent reviewing this IN can be charged to TAC MF969~ To support prompt issuance of the IN, please provide any comments or questions to Nancy Martinez by COB Tuesday, June 6.

The draft IN can be found in ADAMS ML17153A053.

Anyone have new info on Columbia valve?

Also. 1 was thinking about thread friction. 1 would th1nk normai thread friction would be significantly less than the amount it takes to machine the wedge pin to look like a thread.

Maybe a torque/thrust position could explain that delta.

Lionel - with regards to what formula to use. 1 think the licensee is still under the impression that the pre-torque is always applied, hence lifting a load would be ak, right?

But when you loose pre-torque and now thrust the stem down onto the wedge threads, it has to be lowering a load. Could pre-torque being lost explain why KEI missed it?

Because they didn't make that assumption.

At this stage of the process, the wedge pinis assumed to be sheared. This allows the stem to rotate. Should it rotate enough, the disc will be lower in the valve body and likely in the flow stream. Now the threads would have to be evaluated for fretting wear due to flow vibration. The River Bend operating experience noted a sheared pin, loss of preload, and fretting of the wedge/stem threads due to flow vibration because the discs were in the flow stream.

Mike, Greg -

ln light of some of the recent questions coming out of the LaSalle inspection (including the failure analysis report for the Unit 2 HPCS valve), l'm wondering if we should make some small adjustments to the IN (attached) to avoid focusing too much on the stem torqueing issue? For example, the MPR failure analysis report cover letter provides the following conclusion (attached, :

.. . jailure of the valve 2E22-F004 stem-to-wedge connection was due to multiple closing load cycles (with both axial thrust and torque components) which caused loosening and eventual shear failu re of the wedge pin and threads. The loosening and shearfailu.re were caused by an insujj_icient ca acity of the shrinkfit stem collar.

Section 2.2 of the failure report also states "Loss of preload is expected if closing loads exceed the collar slip capacity. Note that small changes in the interference fit and friction coefficient have a significant impact on the collar slip capacity". So, there are a few statements in Friday's draft of the IN that may be a bit too definitive in light of this information. For example, the opening sentence states:

The U.S. Nuclear Regulatory Commission {NRC) is issuing this information notice (IN ) to inform addressees of operating experience regarding Anchor/Darling (a subsidiary of Flowse rve) double disc gate valve (DDGV) non-conformances involvi l'1g inade(1uate tor(1ue of tne ste111 to upper wedge co, 11 ,ection that resulted in stem-to-upper wedge anti-rotation pi n (wedge pin) failu res.

We may want to delete the portion of the actual cause and just leave as non-conformances as shown above. ln the Discussion portion we provide a lat of information from the Flowserve Part 21 (which is taken verbatim), but we may want to add a statement that indicates to licensees that the evaluation of the recent failure event at LaSalle is ongoing and additional information may be available in the near future. For example (and l'm not wedded to this wording ... ):

Licensees ca n use th is information in addition to t he techni cal information provided in the 2013 Flowserve Part 21 report (ADAMS Accession No. ML13064A012) t o consider actions, as appropriate, to avoid sim ilar problems. Licensees should also be aware t hat fa ilure evaluations for t he recent LaSal le Cou nty Station event are conti nui ng and additiona l information may come to light as t hese activit ies progress.

l'm guessing that if the role of the stem-collar in leading to wedge pin failure is verified by Flowserve and/or Exelon 1 an update to the Part 21 would need to be issued. 1 don't want to disrupt the fast track for the IN (which limits how much information we can run to ground),

but we also need to make sure that the IN doesn't narrowly focus on justa portion of the potenti ai problem.

RE: La Salle SIT Update Date: Tu esday,June 06, 2017 8:02:00 AM The only remaining inspection activities for the LaSalle SIT include inspecting the operability of the Unit 1 High Pressure Core Spray injection valve (i.e. , the opposite unit's valve to the one that failed). The team has gane back and forth with the licensee on the development of information that would provide reasonable assurance of operability. The licensee has continuously been updating their operability based on new information developed/provided by the BWROG, the valve vendor, specialty engineering firms, and an independent lab performing the failure analysis evaluation. The mast recent delay was due to the delivery of the failure analysis report that was completed last Wednesday. The team is currently reviewing/inspecting the report and discussing the issues with the licensee.

The team is scheduled to make their recommendation on the operability of the Unit 1 valve by Wednesday. Depending on the recommendation, we will then schedule the exit meeting. Please Iet me know if you have any questions.

Additionally, for your awareness, headquarters entered into the LIC-504 process (i.e. , risk informed decision making procedure developed after Davis Besse) to address the generic implications of the failure. Some actions to be completed include:

- DIRS is working to get an lnformation Notice aut within the next few weeks to highlight the failure at LaSalle and similar other failures of this specific type of valve.

- DIRS is evaluating the need for other forms of generic communications (e.g. ,

Generic Letter, Bulletin, etc.) to require licensees to respond to the agency.

- Vendor lnspection branch will be going aut to the vendor (Flowserve) for an inspection and Region 111 will supplement that inspection with SIT members familiar with the mast recent issue.

Nancy, The attached file is the EIE submission from LaSalle re: Resolution of Anchor Darling Double Disc Gate Valve Part 21 lssues.

However 1 the NRC Document Control Desk has some issues with the submission and I am working with the LaSalle to resolve them.

The information in the letter might be sti li good. Therefore 1 1am sending it to you so you can share it wlth other members of t he LIC-504 group.

Unit 2 Shutdown

Jamie, Sounds like LaSalle Unit 2 may be shutting down due to a recirc pump motor issue. We should be asking abo ut their plans (if any) to go into the HPCS min flow valve. This probably will not have much impact on our Unit 1 operabifüy concerns (since we have ruJed out m uch of the min fl ow valve concerns), but it could provide some rnore data for the overall generic issue. Let me k now when you get to the site tomoffow.

Thanks, Mark Sent from my iPho ne. Please forgive any typos.

Updat e on LaSalle MOV lssue and HQ LIC-504 Process Folks -

Spoke with Ken (Region 111) again this morning. Here's an update on the SIT activities and the LIC-504 implications:

LaSalle SIT

• MPR provided Exelon the failure evaluation for the Unit 2 HPCS lnjection Valve on May

30. This report was distributed to the LIC-504 team last week (Iet me know if you need a copy) . The failure analysis report provided some new information, including the role of stem collar slippage resulting in loss of stem torque preload (the resistance of the stem collar to movement appears to be less than the applied load and repeated loading cycles leading loosening of the stem-disc connection and failure of the wedge pin. Of particular note is that if axial stem loads exceed the press fit collar resistance, the valve

will lose preload (the MPR report concluded that the collar resistance was only about 50-60% of normallv aoolied load) 1'

~ (bj(5) Deliberative Privilege Poteotial Generic lroplications for the UC-504 Process

• lf the role of stem collar slippage is verified, this is a condition that is not described in the Flowserve Part 21 (indicating that the Flowserve Part 21 may be deficient).

Flowserve is apparently thinking along these lines as the QA manager from Flowserve just contacted the DORL PM to get information on the process to update/amend a Part

21) - see attachment #2.

• Vendor lnspection at Flowserve (NRO/DCIP) scheduled for week of July 16.

• The lnformation Notice is on a fast track to be issued by June 16. We should revise some of the language in the draft IN be revised to avoid too narrow a focus on the pre-torque issue and the existing Part 21 (since it may not address the valve issue sufficiently). However, any change we make to the IN at this point should not impact the fast track schedule. DIRS is following up on these changes.

• We are planning to have a public meeting Jn the near term (late June, early July) to gather information from industry on industry actions related to the recent valve issues and the Flowserve Part 21. lf the issues described in the MPR report are verified , then the Part 21 may not completely describe the potential non-conformance and the corrective actions recommended by the Part 21 may not be sufficient to prevent recurrence of the failure. This would underscore the importance of holding this meeting as soon as possible (providing industry will be ready to provide quality information) to support continuation of the LIC-504 decision making process.

• We are starting to get better sense of potential categorizatlon of higher priority anchor darling valves - still preliminary1 but (1) press fit stem collar, (2) actuator output greater than load capability of wedge pin, (3) safety function to open, (4) valve setup that requlres high speed close operation, etc. As we get this better refined, we will be able to better focus on the subset of valves that are more susceptible to failure.

Next Steps

• Next LIC-504 meeting scheduled for Thursday, June 8 at 3:00 pm eastern time (we moved this up in response to the recent information from the MPR failure analysis)

• Target issuance for IN June 16

• Public Meeting late June/early July

• Flowserve Vendor inspectlon - week of July 16.

The difference in valve cycles between U1 (since 1987) and U2 (since unit startup in about 1984) is not significant, or within the margin of error. The only significant difference in valve cycles between the units can be attributed to pre-operational testing . Since only anecdotal data exists for pre-operational testing, there is no cert *

RE: LaSa lle SIT call? Big favor request.

FYI, this is the latest info we have on the Columbia valves:

HPCS-V-12 and V-15 passed diagnostic testing . On disassembly, HPCS-V-12 showed some very slight collar separation and some slight wear on the wedge pin. We have no new info on HPCS-V-15, but expect to know more today ar tomorrow.

We understand you are contacting the CGS valve expert today to get more insight. We stand by to support in any way we can.

As of Friday, 6/2/17, this is what we knew and shared (and is still valid, except that work on V-12 and V-15 was delayed):

lnformation on the condition of the first of 3 Anchor-Darling (A-0) valves in the CGS HPCS system on!y developed in the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Here is a thumbnail bu!lets of what the CGS Residents currently know about HPCS-V-4 (HPCS injection valve):

1. HPCS valve (V-4) traces consistent over life of valve (no anomalous traces)

2. No stem rotation observed prior to auto start of HPCS on 5/25/2017

a. On 5/25, due to an apparent l&C error during a maintenance activity, HPCS auto-started

3. Diagnostic after auto start on 5/25/17 and prior to disassembly 6/1/2017 showed > 10 degrees rotation and open stroke failed trace

a. The BWROG acceptance criteria for stem rotation is </= 5 degrees rotation

4. Stem was connected to upper wedge with minor disp!acement from full insertion (threaded)

5. Stem rotated freely by hand

6. Wedge pin sheared but still in the wedge

7. No FME in valve body

8. Collar minor displacement from stem (mils)

a. This is different than LaSalle who saw significant collar displacement

9. Actuator tripped on thermals after auto start on 5/25/2017

10. Magnesium rotor inspection - satisfactory 11 . Gear actuator possible gear damage awaiting inspection

12. Traces, photos, video, and corrective actions for repair underway (same for V-12, and V-15)

a. V-12 is the HPCS min-flow valve and V-15 is the HPCS suction transfer valve

b. Work on V-12 and V-15 disassembly and inspection over this weekend.

More to come as the CGS Residents get additional information as the licensee inspections continue. Of note - Greg and Lindsay have and continue do a great job following this, and other ongoing outage issues.

Solicitation of Comments 6/6: Dra ft IN on anchor/darling double disc gate va lve (TAC MF9698)

The NRR Generic Communications Branch has been working with the NRR/DIRS Operating Experience Branch to develop the attached/linked draft lnformation Notice (IN) discussing operating experience associated with anchor/darling double disc gate valve wedge pin shearing and will promptly begin the formai concurrence process.

Since these valves are used widely in various diverse safety systems (HPCI, HPCS, RHR, RCS, etc), the NRC staff is working towards issuing this high priority IN within 2 weeks.

The Regions will be part of the formai concurrence chain for this document and concurrence will be requested in the next couple of days from one of your Division Directors (DRP or DRS). You are receiving this e-mail to have an opportunity to review the draft IN and provide comments prior to the formai concurrence process. Time spent reviewing this IN can be charged to TAC MF9698. To support prompt issuance of the IN, please provide any comments or queslions to Nancy Martinez by COB Tuesday June 6.

The draft IN can be found in ADAMS ML17153A053.

This is a heads up that we will be requesting a very prompt review from your organization. 1 currently do not have a draft of the lnformatlon Notice to share, but please be on the lookout for a comment request next week. lf you have any questions, please do not hesitate to contact me.

Update on LaSalle MOV lssue and HQ LIC-504 Process Folks-Spoke with Ken (Region 111) again this morning. Here's an update on the SIT activities and the LIC-504 implications:

LaSaUe SIT

• MPR provided Exelon the failure evaluation for the Unit 2 HPCS lnjection Valve on May

30. This report was distributed to the LIC-504 team last week (Iet me know it you need a copy) . The failure analysis report provided some new information, including the role of stem collar slippage resulting in loss of stem torque preload (the resistance of the stem collar to movement appears to be less than the applied load and repeated loading cycles leading loosening of the stem-d isc connection and failure of the wedge pin. Of particular note is that if axial stem loads exceed the press fit collar resistance , the valve will lose preload (the MPR report concluded that the collar resistance was only about

.* (b)(5) Deliberative Pri vilege PotenUal Generic lmplications for the LIC-504 Process

• lf the role of stem collar slippage is verified , this is a condition that is not described in the Flowserve Part 21 (indicating that the Flowserve Part 21 may be deficient).

Flowserve is apparently thinking along these lines as the QA manager from Flowserve just contacted the DORL PM to get information on the process to update/amend a Part

21) - see attachment #2.

• Vendor lnspection at Flowserve (NRO/DCIP) scheduled for week of July 16.

• The lnformation Notice is on a fast track to be issued by June 16. We should revise some of the language in the draft IN be revised to avoid too narrow a focus on the pre-torque issue and the existing Part 21 (since it may not address the valve issue sufficiently). However, any change we make to the IN at this point should not impact the fast track schedule. DIRS is following up on these changes.

• We are planning to have a public meeting in the near term (late June, early July) to gather information from industry on industry actions related to the recent valve issues and the Flowserve Part 21 . lf the issues described in the MPR report are verified , then the Part 21 may not completely describe the potential non-conformance and the corrective actions recommended by the Part 21 may not be sufficient to prevent recurrence of the failure. This would underscore the importance of holding this meeting as soon as possible (providing industry will be ready to provide quality information) to support continuation of the LIC-504 decision making process.

• We are starting to get better sense of potential categorization of higher priority anchor darling valves - stil! preliminary1 but ( 1) press fit stem collar, (2) actuator output greater t han load capability of wedge pin, (3) safety function to open, (4) valve setup that requires high speed close operation, etc. As we get this better refined, we will be able to better focus on the subset of valves that are more susceptible to failure.

Next Steps

• Next LI C-504 meeting scheduled for Thursday, June 8 at 3:00 pm eastern time (we moved this up in response to the recent information from the MPR failure analysis)

• Target issuance for IN June 16

• Public Meeting late June/early July

• Flowserve Vendor inspection - week of July 16.

Has Scott Burnell reviewed th is? There were a few places where the tone didn't appear to me to be OPA-polished. He could also help with the O&As - both in developing the Qs and helping come up with good As. With respect to the existing Q&As, the message below mentions referring the question on plant safety to the SIT, but l'd really prefer we (DE, DPR, and OPA) come up with an initial answer rather than just turning it over to Region 111.

Thanks foryour patience whi le I got more info.

After conversations with Region 111, NRR, Bill, and Fred, there appears to be comfort with the SIT exit tomorrow to convey the ~ concerns regarding the licensee's basis for operability, at the completion of the SIT's information gathering phase. Next steps or generic implications are not expected to be discussed. NRR/Mike are to be briefed on Tuesday while M ike is in Region 11 1.

As for communications - Region 111 does not have a comm plan ready. They do have the list of operabi lity-evaluation-related concerns t hat they wi ll use to ta lk at the exit, but it is very deta iled. 1 am confirming some key messages with Ken O'Brien and plan to share those with you when re.ady, as well as with the CAs at our routine meeting at 10am tomorrow (same time as exit) .

RE: LaSa lle SIT call? Big favor request.

FYI, this is the latest info we have on the Columbia valves:

HPCS-V-12 and V-15 passed diagnostic testing. On disassembly, HPCS-V-12 showed some very slight collar separation and some slight wear on the wedge pin. We have no new info on HPCS-V-15, but expect to know more today or tomorrow.

We understand you are contacting the CGS valve expert today to get more insight. We stand by to support in any way we can.

As of Friday, 6/2/17, this is what we knew and shared (and is stili valid, except that work on V-12 and V-15 was delayed):

lnformation on the condition of the first of 3 Anchor~Darling (A-0) valves in the CGS

HPCS system only developed in the last 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Here is a thumbnail bullets of what the CGS Residents currently know about HPCS-V-4 (HPCS injection valve):

1. HPCS valve (V-4) traces consistent over life of valve (no anomalous traces)

2. No stem rotation observed prior to auto start of HPCS on 5/25/2017

a. On 5/25, due to an apparent l&C error during a maintenance activity, HPCS auto-started

3. Diagnostic after auto start on 5/25/17 and prior to disassembly 6/ 1/2017 showed > 10 degrees rotation and open stroke failed trace

a. The BWROG acceptance criteria for stem rotation is <I= 5 degrees rotation

4. Stem was connected to upper wedge with minor displacement from full insertion (threaded)

5. Stem rotated freely by hand

6. Wedge pin sheared but sti ll in the wedge

7. No FME in valve body

8. Collar minor displacement from stem (mils)

a. This is different than LaSalle who saw significant collar displacement

Daily Note for LaSalle lmportance: High

Cindy, Please Iet me know if you would like any changes to the proposed bullet:

On June 9, 2017, Region 111 conducted an exit meeting for the Special lnspection at the LaSalle County Nuclear Generating Station. The Special lnspection was initiated on April 24th in response to a Unit 2 High Pressure Core Spray injection valve stem-to-disc separation and the potential generic applicability of the failure mode. The team exited with one Apparent Violation concerning Design Control involving an inadequate 1990 weak link analysis. ln addition, the team identified several concerns with respect to the licensee's operability evaluation of the Unit 1 injection valve and exited with an unresolved item pending further internai discussions of potential regulatory actions.

Thanks!

LaSalle SIT Anchor Darling Double Disc Gate Valve Part 21 Position Paper SIT Assessment Summary:

Special lnspection Team's ldentified lnadeguacies for Unit 1 HPCS Operability

1. Valve has been cycled numerous times since it was replaced in 1987 at closed thrust stem conditions that would have expected to have relaxed any existing pre-torque , broken the wedge pin, plastically deformed the wedge threads and loosening the stem to wedge joint from axial Ioading, and deformed/damaged/broken wedge threads from torsional rotation.

There is no substantial difference in the failed Unit 2 HPCS operating and stem loading history compared to the in-service Unit 1 HPCS injection valve. (Attachment 1 - detailed information that supports this assessment)

2. Historic MOV traces have been proven to be unreliable in detecting stem to wedge thread degradation based upon the team's review of the Unit 2 HPCS injection valve traces.

(Attachment 2 - detailed information that supports this assessment)

3. MOV stem rotation checks have been proven to be an unreliable method in detecting stem to wedge thread degradation. This assessment was based upon the team's review of the Unit 2 HPCS injection valve stem diagnostics, method inaccuracy, method being performed in only one direction for just of the beginning of the stroke, lack of historical information, and based upon the licensee's MPR failu re analysis report that concludes degradation could have been occurring with minimum rotation (i.e. less than 5 degrees). {Attachment 3 -

detailed information that supports this assessment) 4 . lndustry Operating Experience (specifically LaSalle Unit 2 HPC injection valve, Columbia HPCS injection valve, Duke small valves) confirms that for high thrust applications a broken pin and wedge thread degradation including failure can be expected. (Attachment 4 -

(b)(5) Deliberative Privilege l(bXS) DeliberaU,e PtiWlege

. Unit 1 HPCS injection valve number of cycles and cycle loading compared to Unit 2 HPCS injection valve

1. of cycles roughly of the same The information available on the number of valve stroke cycles is readily available only for the last nine refueling outages for each unit. The number of valve cycles for nine outages for U1 is 93 cycles, and the average is 10.333 cycles per outage. Extrapolating this information to account for five additional refueling outages (assumed outages since new valve stem installation in 1987) the total number of cycles would increase to 145 cycles. This total number of cycles does not account for one known thermal cycle (actual system demand). It it is assumed that the thermal cycle only cycled the valve once, the total cycles for U1 would increase to 146 cycles. This number does not include cycles during a long outage between 1998 and 1999 for which no information is available.

A similar assessment is performed for the U2 valve. The number of valve cycles for nine outages for U2 is 86 cycles, and the average cycles per outage is 9.555. Extrapolating this information to account for six additional refueling outages (assumed outages since U2 startup) the total number of cycles would increase to 143 cycles. This total number of cycles does not account for two known thermal cycles. lf it is assumed that a thermal cycle only cycled the valve once. the total cycles for U2 would increase to 145 cycles. This number does not include cycles during a long outage between 1998 and 1999 for which limited information is available.

Therefore, based on known operational cycles, and extrapolating the data for the unknown history of the valves , it can be assumed that the U1 valve has cycled 1 more time than the U2 valve during operation of the units. However, since U2 was subjected to pre-operational testing ,

U2 could have more cycles than U1 . The licensee, through anecdotal data, assumes the U2 valve was cycled about 40-50 times during pre-operational testing . Using the lower end of the anecdotal data, the U2 valve may have had 39 additional cycles compared to the U1 valve.

A similar assessment was performed by the licensee, and they concluded the U2 valve could have as much as 51 additional cycles compared to the U1 valve. T he differences come from manipulation of the data used to develop the averages, and the number of cycles extrapolated for outages for which there is no available information.

It is important to note that the number of valve cycles during an outage could vary from 1-20 cycles. Therefore, the uncertainty of the average can be significant with only nine data points to compare the average to. Applying a rough uncertainty, the tinat number of total cycles could be off by 7-1 O valve cycles. Using this information, in addition to the fact that only anecdotal data exists for the pre-operational cycles of the U2 valve, the team does not believe that there is a significant difference in the number of cycles between the U1 and the U2 valves.

To summarize. the difference in valve cycles between U1 (si nce 1987) and U2 (since unit startup in about 1984) is not sig nificant, or within the margln of error. The only significant difference in valve cycles between the units can be attributed to pre-operational testing . Since only anecdotal data exists for pre-operational testing , there is no certainty associated with how man additional c cles the U2 valve had over the U 1 valve. (b)(5) Deliberative Privilege (b)(5) Deliberative Pri vilege

l(b)(5) Deliberative Privilege Stem thrust in closed direction roughly the same for life of plant Both the Unit 1 and Unit 2 HPCS injection valves had roughly the same open and closed torque and thrust loadings over the life of the plant. This was not a surprise since the valves have an identical design and perform the same safety function. Most significantly was that the close thrust loadings had routinely exceeded over 200 kips which had been determine sufficient to slide the collar up and axial deform the wedge threads loosening the joint. Once the joint loosens, subsequent strokes result in torsional loading and additional wedge thread damage. A detailed discussion from the licensee's MPR failure analysis is provided below and demonstrates that routinely exceeding over 200 kips closed stem thrust will lead to valve failure.

From the MPR report.

The lab results indicate that the wedge pin failed in torsional shear during closing and that the failure occurred early in the valve's service life.

As mentioned above, the wedge pin is installed after the stem is threaded into the upper wedge and preloaded. As such, the stem threads would be in tension such that the pin would react in a direction to prevent unthreading. During a closing stroke, the stem axial thrust would be reacted by the collar, while the torque is reacted by a combination of friction under the collar and friction in the threads. The pin also contributes to the torque reaction if no clearances exist. lf the axial loads exceed the collar slip capacity, then the preload is lost and some of the axial load is transferred to the pin. Without a collar preload, during each subsequent opening and closing stroke, the torque is reacted by the pin and any friction in the threads, while during each closing stroke, the axial load is carried by the pin and collar until movement through the thread clearances is achieved.

During the period when the collar and pin are moving through the thread clearances, they share the reaction to the full axial load applied by the stem. For a 0.5 inch diameter pin made from A306-60 carbon steel (Reference 3), the pin double shear capacity at 0.6 times the ultimate strength is 17 kips (=0.6 times 72 ksi times twice the pin cross-sectional area) based on a maximum specified tensile strength of 72 ksi (Reference 18). The pin material's ultimate strength is estimated to be about 125 ksi based on the average of the as-found hardness reported in the lab report. Using this estimated ultimate strength, the double shear capacity increases to 29 kips. Combining this with the maximum estimated collar resistance of 130 kipsv the total axial capacity is approximately 160 kips, which is still well below the 200+ kip axial loads normally applied. As such, the combined collar and pin axial capacity is not sufficient to prevent further collar axial slip and movement through the thread clearances . ln the process, the movement through the clearance may or may not result in any plastic deformation of the pin.

With collar movement allowing axial motion through the thread clearances, further closing axial loads are reacted by the collar, pin and threads; however, the collar reaction may not occur if the stem experienced any unthreading during prior opening stroke(s). Similarly, the closing torque loads are reacted by collar friction, thread friction , and the wedge pin; however the collar friction may not exist if there was unthreading or collar movement. It is noteci that during the closing stroke, the contribution of the friction is directly related to the axial foad, which is increasing as the torque is increasing, and these loads ramp up quickly as the valve closes

against the seats. ln this dynamic reaction with varying friction conditions , the distribution of the torsional load between the pin and the frictional forces can be indeterminate.

For the nominal 2.25 inch stem diameter at the threads (Reference 3), the pin shear capacities above convert to torsional capacities ranging from 1550 ft-lbs (for minimum specification required ultimate strength) to 2760 ft-lbs (for estimated ultimate strength based on hardness testing) . For torque loads typically above 4000 ft-lbs (as shown in Attachment B), the potential to exceed the pin torsional capacity existed without sufficient thread friction developed. Based on the lab results, the pin failure mode is consistent with these loads.

Per Reference 14, the wedge pin margin was calculated for valve 2E22-F004 to be -1 .7%

(negative 1.7%) using the 2015 as-found measured closing thrust and torque of 220,390 lbf and 4,516.6 ft-lbf because these closing loads resulted in the minimum pin failure margin. The applied closing torque was assumed to be shared by the stem-to-wedge threads and the pin only.

A stem-to-wedge thread COF of 0.117 (based on test data) and a pin material ultimate strength of 67.5 ksi were used. However, the calculated margin cannot be relied upon due to previous degradation of the wedge pin (e.g., reduction in pin cross-sectional area) caused by the previous loads, including the undocumented loads experienced by valve 2E22-F004.

(Historic MOV traces have been proven to be unreliable in detecting stem to wedge thread degradation based upon the team's review of the Unit 2 HPCS injection valve traces.)

Kalsi Engineering was contracted to review the 2015 Unit 2 HPCS injection valve open trace anomaly to determine if a third party would have reached a similar conclusion that the licensee did. Specifically, the anomalies was not indicative of stem to wedge valve degradation and explainable by another mechanism. Kalsi determined that it was appropriate to dispositioned the unlock stem nut anomalies during stem decompression as not an issue related to the part

21. The licensee later provided this letter to the SIT to support their position that a performance deficiency did not exist based upon the licensee's review of historic Unit 2 HPCS injection valve historic traces.

The licensee then changed their opinion part way through the inspection following the team's assessment that the 2015 Unit 2 HPCS injection valve trace (or older traces) did not detect stem to wedge degradation and therefore valve failure could not be foreseen from testing indicators.

Kalsi Engineering was contracted again to provide an assessment if the 2015 anomalies was indicative to stem to wedge threaded connection degradation and, this time , reached a different conclusion based upon the same information.

The team's MOV experts reviewed the data and spoke with Kalsi Engineering and MPR directly several times . The team's conclusion is that there is no evidence, and no adequate explanation that explained how the licensee could reach the conclusion that "pre-hammer blow" data could detect a degraded stem to wedge threaded connection since torque and or thrust is not yet applied to the stem (i.e. worm gear and drive sleeve are not yet connected.) Additionally, the team did not identify any other anomalies in the historic Unit 2 HPCS injection traces that could be correlated to stem to wedge degradation. The team did challenge two Unit 1 HPCS injection valve traces that may be indicative of stem degradation but much like the Unit 2 traces, we just don't know based upon a lack of operating experience.

,. (MOV stem rotation checks have been proven to be an unreliable method in detecting stem to wedge thread degradation.)

The licensee Unit 2 HPCS injection valve stem rotation demonstrates acceptable results . At the time, the acceptance criteria was less than 5-10 degrees of rotation . The Unit 2 HPCS injection valve stem rotational results all met this acceptance criteria . The method is not accurate as described below under the best field circumstances.

The smaller the stem, the more degrees of rotation for a given stem deflection length. The diagram also shows the degrees of stem rotation for a given deflection (.21 ") representing 10° on the Compass diameter.

The table below provides the stem deflection length required to be measured in order to detect the given degrees of stem rotation . Note that for all stems a deflection length of 1/16"-1/8" would need to be measured to detect 5° of stem rotation.

The licensee explained to the team that they marked the stem and aligned an RWP trip ticket against the stem prior to valve stroke. During the initial part of the valve stroke, the individual performing the test would eyeball any stem rotation and mark it on the trip ticket. The trip ticket and associated two dots would then been compared on a fixed degree wheel to obtain stem rotation degrees. The degree wheel used did not account for different size stems and therefore there measurement was done wrong. The stem rotation check was performed in only one direction based upon the as-found position of the valve and only for the initial part of the stroke.

Additionally, the stem rotation checks have only started recently and are not performed every time the valve is cycled.

The licensee's MPR fa ilure ana lysis report determined that even minimal rotational movement per stroke (e.g., less than 5 degrees) can increase thread wear and degradation.

(lndustry Operating Experience (specifically LaSalle Unit 2 HPC injection valve, Columbia HPCS injection valve, Du ke) confirms that for high thrust applications a broken pin and wedge thread degradation including fa ilure can be expected.)

There is no discernable difference between the Unit 2 HPCS injection valve that failed and the Unit 2 HPCS injection valve currently in service regarding valve design, operational history, and torque and thrust loadings. The licensee's failure analysis determined a logical and reasonable explanation for why the Unit 2 valve had failed. Using this operating experience, it is nota matter of "if' but rather, "when the Unit 2 HPCS injection valve will fail inservice.

Columbia's HPCS injection valve wedge pin had failed. The licensee informed the team that the wedge threads had not been evaluated for degradation. The stem threads look good. The Columbia licensee estimated that valve had cycles approximately 200 times since installation which was the same rough estimate for the LaSalle HPCS valves. The Columbia licensee informed the team that he bel ieved the wedge pin had broken a long time ago and identified that the pressfit collar had been pushed up (confirming the design issue for high closed thrust applications). Based upon information from the LaSalle licensee and Columbia licensee, the closed thrust operational conditions was somewhat lower (170-200 kips) as compared to LaSalle 200-230 kips which would explain the difference in the stem to wedge threaded connection.

The 22 + duke valves reviewed as part of the Op Ex did not have any broken pins but did have the press fit collar pushed up. These valves were much smaller 6 inches or smaller as comparted to the 12 inch HPCS injection valves. Based upon the team's review, stem to wedge threaded connection would not have been expected to be degraded or degraded substantially.

A*,end.i ,1um; 8 10 ? .<Js-*,.*x Thanks to all who supported Thursday's call. Here's a summary of the discussions (and please feel free to provide and corrections or comments on items I may have missed).

Highlights:

• NRR/DIRS and NRR/DPR continue to expedite issuance of lnformation Notice on the Anchor Darling Double Disc Gate Valve issue. Goal is to issue IN by June 16. DIRS is resolving comments on the IN (current challenge is balancing desire to include new information from Columbia Operating Experience and Exelon MPR failure report with the expedited schedule).

• NRR/DPR continuing preparations for a public meeting to discuss the industry response to the Flowserve Part 21 and recent operating experience. Meeting will be coordinated with owners groups, Flowserve, and NEI and will assist the staff in assessing the need for further regu latory action following issuance of the lnformation Notice. The objective of this meeting will be to solicit input from industry on recent actions taken with regard to the Flowserve Part 21 in light of LaSalle valve failure. This lnformation will be used to inform the LIC-504 decision-making process. An NEI point of contact has been identified and NEI is willing to support the meeting - a planning call will be conducted in the near future to discuss meeting logistics with NEI.

• R_egion 111 Sp.ecial lnspection T~am exiting on Friday, June 9 (te * * *

. mitigation measures for a potential failure of the Unit 1 HPCS system (e.g., guarding ROIC and ADS), (2) rnspecting the Unlt 1 HPCS valve at the next Mode 4 entry, and (3) inspecting other valves whose operability was questioned by the SIT at the next outage. Exelon's letter is attached.

• NRO/DCIP to conduct vendor inspection at Flowserve durlng the week of ,July 16, 2017

• NRR/DIRS has set up a SharePoint site to collect information -

• Next HQ LIC -504 meetlng will be scheduled for Wednesday, June 14 .

Detailed Summary Meeting cornmenced at 3:00 pm on Thursday, June 8. Representatives trom the following organizations were represented:

• NRR/DE

• NRR/DRA

• NRR/DSS

• NRR/DPR

• NRR/DIRS

• NRO/DCIP

• Regions 111 and IV

Purpose:

Continue discussion of LIC-504 process to address generlc implicatlons arrsing from LaSalle special inspection.

Focus areas for discussion will be:

• Status ot IN development process (target completion 6/16)

• Discuss planning for Follow-up Public Meeting This is the eighth meeting held on the LaSalle LIC-504 lssue - previous meetlngs were held on May 3, May 5, May 1o, May 11 , May 18, May *24, and June 1. Agenda is attached.

Status Reports:

• LaSalle Special lnspection (M. Jetters & J. Benjamin, Region 111) - SIT onsite this week. Focus of team's effort has been on evaluating information in the MPR failure analysis for the Unit 2 HPCS injection valve and operating experience from Columbia. Specific items mentioned include:

Columbia identifled a number of anchor darling double disc gates valves to inspect durlng their ongoing outage, including the HPCS injection valve (similar in design and function to the LaSalle Unit 1 HPCS injection valve). The licensee for Columbia performed an as-found test of the HPCS injection valve and all results were satisfactory (stem rotation check and MOV diagnostics). Subsequent to this testing, there was an inadvertent actuation of the HPCS system, resu lting in a valve operation. Follow-up testing of the valve produced abnormal results for both the stem rotatlon check and MOV dlagnostics. Post testing disassembly and inspection revealed that the wedge pin had sheared and the stem rotated freely in the disc. Exelon acknowledged the slmilarity tn valve design/function to the LaSalle Unit 1 HPCS injection valve, bul concluded

that although the wedge pin falled and the stem was untorqued, the valve could stili stroke and perform its safety function .

Flowserve has indicated their intention to update the Part 21 to reflect the potential loss of pre-torque due to slippage of the press-fft stem collar. As described in the MPR fai lure analysis, ifthe motor actuator has sufficient capability to slip the stem collar (determined to be approximately 50% of normai operating va,lve forces in the case of the Unit 2 LaSalle valve tailure), the slippage will result in loss of stem/disc pre-torque (and would potentially negate any corrective actions performed per the current Part 21 notification).

Region 3 received the "reverse Confirrnatory Action Latter" frorn Exelon (dated June 2) - the letter (attached) commits Exelon to repair the Unit 1 HPCS inJection valve during the next Mode 4 entry, to limit elective unavailability of redu ndant systems (e.g., ADS/ LPSI, RCIC), and inspect/repair other affected valves during the next outa e.

A teleconferencewith Region 111 and NRR senior managernent is scheduled forTuesday, June 13.

Exelon rs scheduled for a drop-in meetings today in HQ

• lnteractions with PWROG/BWROG (B. Benney, L. Watkins, NRR/DPR) - PWROG has requested permission trom the QBWROG tor approval to send Revision 3 of the BWROG A/0 OD Disc Valve guidance to the PWROG members. Have requested DPR to verify the revision number for the BWROG guidance since there have been several versions drculated recently.

• lnteractions with Flowserve (J. Burke, NRO/DCIP)- J. Burke (NRO/DCIP) noted that a vendor inspection will be conducted ai Flowserve the week ot July 16. NRO/ DCIP has been in communication wrth Flowserve and reported that Flowserve intends to supplement/amend the previous Part 21 report to reflect recent lnsights regarding the role of slippage of the press fit stem collar Fn the loss of valve pre-torque.

• lnteractions with INPO (E. Thomas, NRR/DIRS) - Nothing new to report.

• lnteractions with NEI (G. Bow man, NRR/DPR)- K. Coyne reported on G. Bowman's behalf, the following : G. Bowman met with Greg Krueger from NEI earller this week for a quick kickoff discussion. G. Krueger indicated that NEI is very much aware oi the LaSalle issue and they've been coordinating with the OGs, INPO, and others on indus1ry actions. As adata point, NEI indicated that he's been brlefing NEI senior managers on a recurrfng basis. G. Bowman discussed plans for the public meeting later this month and NEI seemed very receptive to helping coordinate the industry's presentation. DPR noted that once we have a good handle on the information we need from the industry, NRC would set up a plann1ng call With him to run through that, such tllat they're prepared to gve us what we need.

Schedule tor lssuance of IN - NRR/DIRS (J. Thompson) reported that DIRS is address1ng comments on the draft IN. DIRS noted that they may have some chalfenges in resolving ali comments in accordance with the schedule rnilestone of Friday, June 8 , but the team stressed the importance oi keeping the IN on track for issuance on Fiday June 16. DPR (N. Martinez) noted that if DIRS is slightly delayed, the schedule could stili be maintained if Division concurrence can be accelerated (the IN will require the concurrence from approximately 7 Divisions and the Regions).

Emphasized to ali team members that once the IN is ready for concurrence, it needs to be turned around quickly.

The IN is written at a high Ievel and provides an overview of recent operating experience (LaSalle, Browns Ferry, Surry, River Bend).

Status of Public Meeting - NRR/NRR (K. Coyne) discussed the planning goals for pubHc meeting with industry to discuss recent actions taken to address anchor darling valve fatlures . This meeting wlJI be used to gather information to support the NRC's LIC-504 process. The goal of this interaction is to gather information about industry actlons in response to recent anchor darling valve issues. This information will be used to assess and implement the most appropriate regulatory response (e.g., monitor voluntary industry initiative, generic communication, etc.). The team discussed the meeting to schedute this meeting as soon as posslble (balancfng urgency against the need to ensure that industry counterparts have sufficient prep time to provide quality information). Briefly discussed preliminary questions for industry and requested team members to provfde feedback/correctlons/revisions/additions as soon as possible. The prellminary questions are included in the agenda and provided below:

• Characterization of Anchor Darling double disc gate valve population Number in service in safety-related or risk-significant functions?

RE: Flowserve doc

James, 1 think, the SIT should make the decision whether the NRC wants the document submitted "on Docket. "

LaSalle told me essentially, the same thing, even though the letter was sent to LaSalle. 1 believe, SIT received the Letter from LaSalle asa part of SIT.

Re: SIT exit at laSalle Date: Monday, June 12, 2017 7:37:56 AM Chris Exited with a traditional violation of Crite1ion UI, Design Control, associated with the Unit 2 HPCS valve aod its design being inappropriate for the cbosen application, base in part on the licensee's MPR analysis. No severity level identified and no PD associated with the violation.

Also exited with an URI associated with the licensee' handling of the remainder of the AD vales, most significantly the Unit l HPCS valve and operability evaluation. This will allow us to define a final course of action as we brief up the management chain. Currently have a brief of Bi11 and Mike Johnson scheduled fir Tuesday, noon my tie.

Re: SIT exit at LaSa lle Chris Exit went we]l.

No specific or additiona] commitments.

Side, hypothetical conversation on how the agency may respond if the licensee chose to shutdown voluntarily in the near future, out of an abundance of caution, to open the valve and undertake any necessary repairs. The thought was paired with the licensee identifying a good point in the weather over the next few weeks.

Also -inquired as to the likely time line it may take to issue an order.

Otherwise, relatively straightforward exit.

RE: AD valve fa ilure rates lmportance: High John-Another high priority data question - can we get a better sense of the contribution to the anchor darling valve failure rate from large valves (e.g., say greater than 6-8" in size) vs smaller valves (e.g., less than 6"). This is becoming a key question in the LIC-504 assessment - we are trying to determine if we have any evidence that would substantiate that the stem/disc separation issue (or wedge pin failure) is more closely correlated with larger size valves. Any insights we might have about the size breakdown for the population of anchor darling valves vs the observed failures would be useful. For example (to make up some numbers ... ), if large valves only make up 10% ot the anchor darling valve population but account for 90% of the observed failures, that would be a good data point for consideration for the generic LIC-504 question. 1 know there is a limit to what INL can extract from the INPO data feed, but any quick insights would be appreclated. And we're obviously focusing on mechanical failure of the valves (e.g., stem disc separation or degradation) rather than other failure causes (limit switch, electrical, etc.). 1think folks in NRR/DIRS can also assist as needed (Harald Chernoff would be a good contact).

Thanks!

[External_Sender] AD valve fa ilure rat es

John, I think I have a series of queries set up that I can use to produce failure rates based on a number of different specifications working on manufacturer and valve type/subcomponent.

It looks to me like we really don't need reliability information on the valves because we can use calendar years for some period in the denominator. This allows me to cast a much larger net for failures reported in ICES. When I do thi s for just valve subcomponent failures for AD gate valves l get 38 faiJures (includ.i.ng aJJ failure modes). We bave about 38,726 calendar years of valve operation with this valve population since 1998. This yields a failure rate of about l.lE-7/hr.

When I use the same queries to get valve subcomponent failures for ali MOVs that are gate valves and not AD valves, I get 55 failures in 150,376 calendar years of valve operation for a failme rate of about 4.2E-8/hr So it looks like AD gate valve failures are, generally speaking, about 2.7 times as likely as non-AD gate valve failures ( again, removing failures related to the actuator where possible).

There are many possible ways to slice and dice to refine this result. Probably some caveats I should be mentioning as well. So it is bard to know where to go nexl without some additional discussion.

Justa reminder, I am away from work Thursday through Mo nday . Shawn is also away, but

for somewhat ]onger.

Please see attached agenda for this afternoon's LIC-504 meeting. A couple of noies:

• Please take a look ai lhe safety assessment (pages 6 and 7) - there has been a lot of new tnformation developed asa result of the great work being done by the LaSalle Speclal lnspection Team and we want to make sure the assessment is staying current.

• A high priority for the LIC-504 effort is setting up the public meeting with industry to gather critical information needed to support future regulatory decision-making on the generic part of this issue. To that end, we have a working list of questions we want lndustry to come prepared to discuss. Working draft of the question list is on pages 3 -4 (and thanks for the comments on the earlier version). l'd like to finaljze these at this afternoon's meeting so we can move forward with coordinating the pubfic meeting wilh industry slakeholders.

• DIRS/IOEB has been mainlaining a SharePoint site with Anchor Darling MOV information - greal resource and includes a lol of the documenlalion thal has been passed along in emails over the last several weeks. The site is localed at:

http://fus ion.nrc.gov/nrr/team/dirs/ioeh/a nchor clarling va lve issue/default.a.~px .

• DPR has pulled logether a good working draft of the communication plan (Brain Benney is coordinating). The latest is on SharePoint (hJJp*//fu~ion nre.gov/nrr/team/dirs/ioeh/anchor darling valve jssue/Shared%-20Documents/LaSa)Je%,20Co1111nunica1j<m'k-?OPlan%? ().

• l've also attached the summary from last week's meeting - please review the action items at the end of the summary and be prepared to discuss status.

• Finally, l've attached a Flowserve advertisement lor a "design enhancement" to eliminate torsional loads on the valve disc pack and "improve its reliable operation". The design enhancement eliminates the threaded stem disc connection (using a t-connection) and adds a slotted stem with an anti-rotation collar. The advertisemenl is dated 2014 .. .

Thanks to ali for the tremendous support of thls effort -

NR R Key Messages for LaSa lle HPCS Operabil ity Question Brian -

Here's a rundown on the key messages you requested - has been vetted through DE, DSS, DIRS, and DPR.

(b)(5) Deliberative Pri vilege

• The LaSall.e Special lnspection Team (SIT) has done excellent work and raised significant questions about the operability of the Unit 1 HPCS injection valve. ln particular, the SIT's conclusion that valve actuator forces are sufficient to shear the valve wedge pin and degrade the threaded connection have not been adequately addressed by Exelon's operability evaluation. Exelon should revise/update their operability evaluation to address the questions raised by the SIT and provide assurance of continued operability of the Unit 1 HPCS valve.

• Although shearing of the valve wedge pin represents a degraded condition for the valve, operating experience indicates that there is a latency period between wedge pin failure and stem-disc separation. Based on the MPR failure analysis conducted for the Unit 2 HPCS injection valve, the most likely failure sequence following wedge pin failure involves thread degradation and wear over multiple valve operating cycles. The latency eriod between wed e in shearin and valve failure m

• Although there have been recorded failures of anchor darling double disc gate valves in the operating experience over the last several years, l'-""...-14.:u.~~.a.u.u.u..u.L..u.u.LCi.Uw.a.iLLlL.._

im _acted valves has not been s ecificall identified.

( )(5) Deliberative Privilege

• A risk assessment conducted by Region 3 assuming complete failure of the Unit 1 HPCS valve during an 8 month exposure window resulted in an incremental conditional core damage probability of 1.?E-05 (1.3E-05 when Exelon 's compensatory measures of reducing elective maintenance on ADS, RC IC, RHR and LPCS were modeled by decreasing T&M unavailability by a factor of 10). Although this risk estimate does not include contributions from external events or fires, there is significant margin to the stated LIC-504 risk metric threshold for "high" risk impact of ICCDP on the order of or greater than SE-05. Use of a more realistic failure probability for the HPCS injection valve would further increase available margin to this th reshold.

• The loss of HPCS injection does not result in a significant loss of defense in depth as other means exist to provide makeup water to the reactor (e.g., RCIC or low pressure injection following depressurization).

• The HO LIC-504 effort will continue to evaluate the issue and any eventual outcome would apply to the LaSalle plant.

Anchor Darling DDGVs - Data insights on failu re rate vs. Va lve Size Bill, Brian-RES/DRA and INL worked with the INPO data feed and came up with some population estimates based on the sizing of Anchor Darling DDGVs. This is preliminary information as there are stili a few questions about the completeness of the INPO data (RES is running these down), but here's a quick summary of what we have right now (... detailed data is attached):

Valve Size # of valves # of failures Calendar Year Failure Rate (CV) (exposure) /CY

.5"-2" 38 1 686.17 1.5E-03 2"- 4" 251 8 4276.50 1.9E-03 4 -12" 1163 18 20737.67 8.7E-04

12" -20" 430 4 7769 5.1 E-04 20" -40" 229 7 4348.67 1.6E-03 A couple of quick observations -

• These include all failure causes for the valve - fail to open/close, and leakage (so stem-disc separation failure events would be lower). Actuators are excluded from the failure counts.

• With the exception of the 20 - 40" valves (which generally seem to be steam stops, loop isolations, containment sumps, or RHR inlets), the larger valves have a sl ightly lower failure rate than the smaller valves . Although we don't have a lot of resolution in the 4-12" size range , this data does not seem to support a general conclusion that larger valves are more susceptible to failure.

• For the range of most interest for the LaSalle issue (4-12"), the 18 failures seem to be associated with the following valve types:

i.,. HPCI Main Steam Line lsolation Valve (7)

i.,. HPCI Discharge to Feedwater lsolation Valve (1)

i.,. LPCS Discharge To Reactor Spray lsolation Valve (1)

i.,. lsolation Condenser Condensate Containment lsolation Valve (3)

i.,. Aux/Emerg Feedwater Pump Alternate Source Suction Valve (1)

i.,. Containment Spray Discharge to Header lsolation Valve (1)

i.,. SI Pump Suction lsolation (1)

i.,. Primary Containment lsolation Valve (2)

i.,. RHR Discharge lsolation Valve (1)

My guess is that most of these valves are at the larger end of the 4" - 12" spectrum. It is noteworthy that 6 of these fai lures are associated with only two valves.

• There is more art than science in interpreting some of the INPO data fields, but this at least gives us a ballpark for the population - approximately 2, 100 valves in service with valves 12" or greater accounting for about 1/3 of the population (659) and -1/3 of the recorded failures (11 ).

RE: Columbia DDGV Ryan:

Per NRR/0/RS' request The short answer to the question is NO, CGS did not declare HPCS-V-4 inoperable when they found the wedge pin sheared, but this was because the HPCS system was already inoperable for maintenance and was not rel ied upon for shutdown risk. (LPCI-A and LPCS were the two credited ECCS systems to meet TS 3.5.2 at the time.) More details below:

ln Oecember 2016, the licensee monitored for stem rotation (2 year frequency) on HPCS-V-4 (HPCS injection valve - an Anchor-Darling DDGV) and did NOT identify any abnormalities. On 8/ 19/2011 , the licensee conducted a diagnostic test & trace (6 year trequency) for the HPCS-V no anomalies were noted, and there no stem rotation was noteci.

CGS entered its current refueling outage during the weekend of 5/13/2017.

CGS entered Mode 4 at 1234 on 5/13/17, and Mode 5 at 1342 on 5/14/2017.

Upon entry in to Mode 4, TS 3.5.2 "ECCS - Shutdown became applicable, requiring IwQ ECCS injection/spray subsystems shall be OPERABLE." At CGS, the ECCS injection/spray subsystems are defined as the three Low Pressure Core lnjection (LPCI) subsystems, the Low Pressure Core Spray (LPCS) System, and the High Pressure Core Spray (HPCS) System. LPCI-A, LPCI-C, and LPCS were protected for shutdown risk.

On 5/25/2017, during l&C inadequate maintenance on a common reference leg, HPCS auto-started due to an invalid insertion of a Level 2 signal into the system concurrent with an actual Level 8 signal sealed in. The cavity was flooded up with the fuel pool gates removed. HPCS-V-4 started to open a couple of turns, but when the inadvertent Level 2 signal cleared, the Level 8 logic "caught up" and the motor made a prompt reversai in direction to close the valve. The motor then tripped on thermals. The licensee stated the prompt reverse torque applied by the motor o erator to close the valve was the cause o~

the sheared pin. A diagnostic test for HPCS-V-4 on 5/31 /2017 showed > 1O degrees of stem rotation. On 6/ 1/17, the licensee disassembled HPCS-V-4 and found the wedge pin sheared.

As of 6/12/17, licensee had replaced the internais for HPCS-V-4, including using an lnconel pin and with the valve stem torqued to the upper disc in accordance with the vendor recommendations. Further, the licensee has verified that the MOV Motor torque is set such that it is less than the combined stem-to-upper disc torque plus the lnconel pin torque limit, thereby mitigating the risk of the internai valve component failure.

We do not have a source of information that provides the number of valves used at each site or the total population of the valves in service.

We would either need to formally request the information from licensees; have inspectors gather the information; or toster an industry initiative to gather the information.

Harold, Here is what I can glean from the table ( can take a close look at each when I am back in the office ).

This is over what time frame and how many resulted in inoperab/e valves?

1993- 2017 Pretty sure they were all valve failures.

And do we have info that shows whether issues were found in periodic testing!inspection or where result of a demand failure?

Looks like about 7 were during maintenance, 4 during operations (Demand), and 2 that I couldn't figure out from the table (probably maintenance though)

Anchor Darling Valve lssue 2

Bifl, Chris came by and asked that I summarize the OpE information on Anchor-Darling (A-0) double disc gate valve failures that we extracted from our data sources (primarily ICES) .

• We found a total of 13 items that appear at least partially related to the LaSalle Unit 2 issue.

• 11 of these involved A-0 double disc gate valves.

We ranked these from A to C based on relevance of the information to the LaSalle Unit 2 issue (i. e., A-0 DDGV with stem separation "A"; A-0 DDGV with degraded stem connection (e.g., thread wear, pin failure) B";

other similar valves with pin failures or stem separation "C")

• "A" Ranked Valves - total of 4 0 2-32

0 1 - 20" 0 1 -12"

• "B" Ranked Valves - total of 7 0 2-20" 0 4-10" 0 1 - 4"

• "C" Ranked Valves - total of 2 o 1 - size reported as 4"-12" nota DDGV o 1 - size reported as 2"-4" A-0 parallel disc gate valve We do not have a source of information that provides the number of valves used at each site or the total population of the valves in service.

Date: Thursday, June 1S, 2017 11:58:33 AM Attachments: Ag~nda !Hac 14 2017 cJocx TPJ7- -l J? VTG F)nwservc Pur 1 J Rev2 pdf

• • • Note that attachment (TP 17-1-112) contains proprietary information ****

Thanks to all who supported Wednesday's call. Here's a summary of the discussions (and please feel free to provide and corrections or comments on items I may have missed).

Highlights:

• lssuance of lnformation Notice on the Anchor Darling Double Disc Gate Valve issue is on track for issuance on Thursday, June 15 (ahead of schedule). Being coordinated with update to the Communication plan. Thanks to all who supported this milestone.

• NRR/DPR continuing preparations for a public meeting to discuss the industry response to the Flowserve Part 21 and recent operating experience. Meeting will be coordinated with owners groups, Flowserve, and NEI and will assist the staff in assessing the need for further regu latory action following issuance of the lnformation Notice. The objective of this meeting is to solicit industry input on recent actions taken with regard to the Flowserve Part 21 in light of LaSalle valve failure. This information will be used to inform the LIC-504 decision-making process. An NEI point of contact (Greg Krueger) has been identified and NEI is will ing to support the meeting - a planning drop-in meeting will be conducted with NEI on Thu rsday, June 15, to facilitate logistics for the public meeting.

• Region 111 Special lnspection Team exited on Friday, June 9. The SIT exited with the following preliminary issues (subject to management review and approval): (1) an apparent violation for design control issue associated with the Unit 2 HPCS injection valve failure (will be handled under traditional enforcement process), and (2) an unresolved issue (URI) associated with the adequacy of the licensee's operability evaluation for the Unit 1 HPCS injection valve. Region 111 and NRR are in the alignment process for addressing the URI.

• NRO/DCIP to conduct vendor inspection at Flowserve during the week of July 16, 2017

• NRR/DIRS has set up a SharePoint site to collect information -

http :/Jfusion.mc.gov/nrr/tearn/dirs/ioeb/auchor darli ng valve issue/default. asp.x

• Next HO LIC-504 meeting will be scheduled a few days prior to the public meeting mentioned above (late June, early July).

Detailed Summary Meeting commenced at 3:00 pm on Wednesday, June 14. Representatives from the following organ izations were represented :

• NRR/DE

• NRR/DRA

• NRR/DSS

• NRR/DPR

• NRR/DIRS

• NRO/DCIP

• Regions 111 and IV

• OEDO

Purpose:

Continue discussion of LIC-504 process to address generic implications arising from LaSalle special inspection. Focus areas tor discussion will be:

• Status of IN development process (target completion 6/16)

• Discuss planning for Follow-up Public Meeting Th is is the ninth meeting held on the LaSalle LIC-504 issue - previous meetings were held on May 3, May 5, May 10, May 11 , May 18, May 24, June 1, and June 8. Agenda is attached.

Status Reports:

• LaSalle Special lnspection (M. Jeffers, Region 111)- Special lnspection Team exited on Friday, June 9. The SIT exited with the following preliminary issues (subject to management review and approval): (1) an apparent violation for design control issue associated with the Unit 2 HPCS injection valve failure (will be handled under traditional enforcement process), and (2) an unresolved issue (URI) associated with the adequacy of the licensee's operability evaluation for the Unit 1 HPCS injection valve. Region 111 and NRR are in the alignment process for addressing the URI.

• lnteractions with PWROG/BWROG (B. Benney, L. Watkins, NRR/DPR) - PWROG received permission from the BWROG to send Revisions 2 and 3 of the BWROG A/D OD Disc Valve guidance to the PWROG members. Per the BWROG, the, varrous report revisions are ldentified as:

Original Release "BWROG-TP-13-006".

Revision 1 - Update to incorporate Operating Experience based on industry inspections -Addendum 1. (Distributed as TP16-1-112 r1 due to BWROG document naming convention change).

Revision 2 - Revision to incorporate lessons learned and recommendations resulting from a stem/disc separation event that occurred at Exelon's LaSalle Station in February 2017. The document has been rewritten to better integrate the latest operating experience and recommendations. Addendum 1 has been eliminated with applicable information incorporated into the body of the report. (Distributed as TP17-1-112 but should have been TP1 6-1 -112 r2). This report is attached for information.

Revision 3 - Update to incorporate comments from Flowserve and others to facilitate formai Flowserve Corporation endorsement of the updated Topical Report. (TP16-1 -1 12 r3) . A copy of this guidance is currently not available to staff.

The BWROG has indicated that their preference for supporting a public meeting was July 18. This date later than needed to support a timely decision making process and conflicts with planned vendor inspection activities at Flowserve. More discussion follows later in this summary.

• lnteractions with Flowserve (J. Burke, NRO/DCIP) -J. Burke (NRO/DCIP) noted that

a vendor inspection will be conducted at Flowserve the week of July 16. Andy Dunlop and Lionel Rodriguez from Region 111 will also be supporting the vendor inspection.

• lnteractions with INPO (E. Thomas, NRR/DIRS) - Nothing new to report.

• lnteractions with NEI (G. Bowman, NRR/DPR)-A logistical planning drop in with NEI is scheduled for Thursday, June 15. The goal is to communicate NRC goals and objectives for the public meeting to ensure industry will be prepared to provide needed information. There was discussion on need to address information collection 0MB requirements. NRR/DPR will follow-up on process controls needed to ensure appropriate information collection. NEI has expressed a willingness to coordinate industry actions on this issue.

• Risk Assessment (J. Circle, NRR/DRA) - NRR/DRA is continuing to work on documentation for risk analysis.

LIC-504 Topies:

• Re-affirmed Qualitative Risk Assessment (K. Coyne, NRR/DE) - The team discussed the risk assessment supporting the conclusion that there was not a need for immediate regulatory action per the guidance in LIC-504 and reaffirmed that this issue does not require immediate regulatory action. The assessment was modified as follows:

Preliminary Assessment

1. Anchor Darling Double Disc Gate Valves (DDGVs) are used in safety-related and risk-significant applications at over 40 plant sites. These valves are used in both PWR and BWR plant applications, including emergency core cooling, residual heat removal, and service water systems.

2. The under-torqued stem condition described in the TVA and Flowserve Part 21 reports may have existed since initial plant construction. ln addition, for valves with a press fit stem collar, slippage of the collar (due to operating forces greater than the resistance from the collar) can result in loss of stem pre-torque.

3. Although the under-torqued stem condition can lead to wedge pin shearing and eventual valve failure, the staff has identified that only a small portion of the in-service valves have known failures due to wedge pin shearing. Based on adata analysis conducted by INL, the estimated failure rate based on operating experience for A/D DDGVs is approximately 1E-03/year, slightly worse than the non-ND valve population (note that this estimate pools all anchor darling valves regardless of size and includes all failure modes). However, there is uncertainty about the correlation between valve size and susceptibility to failure - this remains an open question.

4. Limiting the shear stress applied to the wedge pin by either (1) the use of a motor actuator incapable of generating sufficient torque, or (2) by valve setup (e.g., setting of torque switches at a low enough value) may prevent wedge pin and subsequent failure of valve.

5. Failure of wedge pin does not immediately lead to valve failure. Based on operating experience, there appears to be a latency period following wedge pin failure before gross failure of the valve occurs.

6. Operating experience from Duke disassembly and inspection of more than 23 valves indicated that all but two valves were untorqued. However, none of the under-torqued valves had a sheared wedge pin; stem or disc damage; or was in a failed condition prior to disassembly. This operating experience was associated with smaller sized anchor darling valves.

7. A risk assessment conducted for 11 plants using conservative assumptions (e.g. ,

increase in fai lure rate of all MOVs by a factor of -11) indicates that the increase in CDF associated with the degraded valve conditions constitutes a small increase in CDF (approximately less than 1 E-05/yr).

8. The staff is not aware of any other information at this time that would require immediate regulatory action Therefore , the preliminary conclusion is that wh ile reliability of the affected valves may be degraded, the condition identified in the Part 21 notifications and related design defect associated with the potential for stem collar slippage does not result in an immediate safety concern .

• LIC-504 Decision Options (K. Coyne, NRR/DE) - The team next discussed the following topies:

- Schedule for lssuance of IN - NRR/DPR (N. Martinez) reported that all concurrences have been received on the draft lnformation Notice and it is currently ahead of schedule. The IN could be issued as early as Thu rsday, June 15.

- Status of Public Meeting - NRR/ NRR (K. Coyne) discussed the planning goals for public meeting w ith industry to discuss recent actions taken to address anchor darling valve failures. This meeting will be used to gather information to support the NRC's LIC-504 process. The goal of this interaction is to gather information about industry actions in response to recent anchor darling valve issues. This information will be used to assess and implement the mast appropriate regulatory response (e.g., monitor voluntary industry initiative, generic commun ication, etc.). The team finalized a list of questions to focus the upcoming public meeting discussions:

• Characterization of the population of Anchor/Darling Double Disc Gate Valves (DDGVs) with threaded stem-disc connections in nuclear service

- Total number in service

- Distribution by valve size (e.g. , percentage of population in each size sub-group)

- Actuators typically paired with various valves sizes

- Systems where valves are used

• What valve characteristics or operating conditions increase susceptibility to wedge pin failure and subsequent stem disc separation failure?

- How shou ld valve characteristics/conditions be used to prioritize resolution of issues for Anchor/ Darling DDGVs.

• What corrective actions are needed to resolve the Anchor/ Darling DDGV pre-torqueing and design issues?

• What industry actions have been performed (or are planned) in response to Anchor/ Darling DDGV issues (e.g., Part 21 notifications, recent operating experience)?

- Failure evaluations

- lnspections

- Repairs/modifications

- Schedule for future actions

• What testing or inspection procedures (if any) can be used to identify a degraded condition or incipient failure without valve disassembly (beyond stem rotation checks and MOV diagnostics whose effectiveness are currently being questioned by the NRC)?

• Has the extent of condition been evaluated for other valve or actuator types (e.g., Anchor/Darling DDGVs with T connection, other supplier valves with threaded stem-disc connection)?

• Perspectives and insights related to the risks associated with continued operation with a potential degraded condition for Anchor Darling DDGVs

• Plans for coordinated industry actions in response to Anchor Darling DDGV issues

- lndustry plans and schedule for updating Anchor/Darling DDGV guidance documents (e.g., Part 21s, BWROG guidance)

- lndustry wide guidance for inspection/repair of affected valves To facilitate logistics for the public meeting, G. Bowman (NRR/DIRS), K. Coyne (NRR/ DE), M. King (NRR/DIRS), and K. O'Brien (Region 111/DRS) plan to have a drop in meeting with NEI (G. Krueger) to discuss the purpose and objectives for the meetings and scheduling considerations. This drop-in is scheduled for Thursday ,

June 15. With regard to scheduling the publ ic meeting, NRO (J. Burke) requested that the week of July 17 be avoided due to conflict with the planned vendor inspection at Flowserve.

• Communication Plan (B. Benney, NRR/DPR} - The draft communications plan is posted on the DIRS SharePoint site (http:Ufusion.nrc.gov/nrr/team/Jjn,/joeb/anchor darling valve jssue/uefault aspx: ). The plan will be updated periodically. The team was encouraged to review the plan and provide any comments or suggestions to Brian Benney who will continue to coordinate the comm plan. Jn particular, the section on Questions and Answers can use further development.

• Next Meeting (K. Coyne, NRR/DE) - The next LIC-504 meeting will be scheduled prior to the public meetng to ensure staff alignment prior to meeting with external stakeholders.

Next Meeting: tbd (but will be scheduled several days before the public meeting with industry stakeholders)

Action ltems:

ALL

• Provide potential questions for Flowserve to NRO/DCIP (John Burke) for possible inclusion in the Flowserve vendor inspection plan.

• Provide input for LIC-504 decision options and informatlon needs as appropriate.

• Provide feedback on communlcation plan to Brian Benney (NRR/DPR)

(hup ://fusion. nrc. gov /nrr/lca.m/<l irs/ioeb/:mchor_ darl ing_ vai ve_iss ue/<ldaul t.aspx ).

NRR/DE

• Follow-up with RES to determine if there is more A/D DDGV data to differentiate reliability history vs. size (K. Coyne).

NRR/DPR:

He stated the NRC is a very collegial organization, which he then said means a lot of people are consulted before a decision is made. Post 9/11, they had to change their process for decisions that needed to be made in a very short time frame. Effectively, they limited the decision maker to 1 person in order for the decision to be made in a timely manner.

And getting a chance to work again with Region 111 has been a highlight of the rotation for me so I appreciate the candid dialogue we've been able to have on this. A couple of items I just wanted to run by you (and 1'11 be in the office for a little bit more if you want to Skype) :

• When you draft up the key messages for the calls Mike J and Cindy will be making (you took away that action, correct ©), can you send them to both me and John?

Slnce 1'11 be on leave, John will take a quick look. Also, 1think Mlke was looking at making the call on Tuesday1 rather than Monday, to allow a little more time for Region 111/NRR alignment on the messages.

• We're on the hook for the July 5 presentation for the safety spotlight during the OEDO Quarterly Strategic Alignment Meeting. l'm planning to cobble together about 5 slides or so - heavy on graphics to support a 10 minute discussion. As far as the SIT and LIC-504, 1wasn't going to go into many details - maybe just put a bullet for current status we can speak to for each effort. 1'11 try to send you something to take a look at in the next day or two to keep the ball rolling.

1'11 be out of the office for the next two weeks, but will be checking emails periodically -

particularly ones related to A/0 valves - and will likely be going to the June 29 public meeting regardless.

Hope you have a good weekend -

From: McDermott Brian To: O"Brien Kenneth Subj ect: RE: Anchor Darling DDGVs - Data insights on fa llure rate vs . Valve Size Date: Friday, J une 16, 2017 9:05:46 AM Quick question/thought- was there a performance deficiency regarding the licensee's weak-link analysis? Was there a problem with how the LaSalle plant did its analysis for the HPCS valves or is there some "new information" that would lead us to believe that there is a generic issue with how weak-link analyses are being performed across the industry?

lf plants do the weak-link analysis properly, following their established MOV programs, 1 would not expect failures resulting from setting a torque switch in a way that overloads the valve.

Anchor Darling DDGVs - Data insight s on fa ilu re rate vs. Va lve Size Bill, Brian -

RES/DRA and INL worked with the INPO data feed and came up with some population estimates based on the sizing of Anchor Darling DDGVs. This is preliminary information as there are still a few questions about the completeness of the INPO data (RES is running these down), but here's a quick summary of what we have right now (... detailed data is attached):

Valve Size # of valves # of failures Calendar Year Failure Rate

{CV) {exposure) /CY

.5" -2" 38 1 686.17 1.5E-03 2" -4" 251 8 4276.50 1.9E-03 4" -12" 1163 18 20737.67 8.7E-04 12" -20" 430 4 7769 5.1 E-04 20" -40" 229 7 4348.67 1.6E-03 A couple of quick observations -

• These include ali failure causes for the valve - fail to open/close , and leakage (so stem-disc separation failure events would be lower). Actuators are excluded from the failure counts.

• With the exception of the 20 - 40" valves (which generally seem to be steam stops, loop isolations, containment sumps, or RHR inlets), the larger valves have a slightly lower failure rate than the smaller valves . Although we don't have a lot of resolution in the 4-12" size range, this data does not seem to support a general conclusion that larger valves are more susceptible to failure.

• For the range of most interest for the LaSalle issue (4-12"), the 18 failures seem to be asso.ciated with the following valve types:

~ HPCI Main Steam Line lsolation Valve (7)

~ HPCI Discharge to Feedwater lsolation Valve (1)

~ LPCS Discharge To Reactor Spray lsolation Valve (1)

> lsolation Condenser Condensate Containment lsolation Valve (3)

>> Aux/Emerg Feedwater Pump Alternate Source Suction Valve (1 )

)"' Containment Spray Discharge to Header lsolation Valve (1)

};.> SI Pump Suction lsolation (1)

~ Primary Containment lsolation Valve (2)

>> RHR Discharge lsolation Valve (1 )

My guess is that most of these valves are at t he larger end of the 4" - 12" spectrum. It is noteworthy that 6 of these failures are associated with only two valves.

• There is more art than science in interpreting some of the INPO data fields, but this at least gives us a ballpark for the population - approximately 2, 100 valves in

service with valves 12" or greater accounting for about 1/3 of the population (659) and -1/3 of the recorded failures (1 1).

Many thanks to John Lane in RES/DRA and John Schroeder out at INL for pulling this information together -

It at least tells us there are a lot of these valves out there with a very low failure rate.

RE: Anchor Darling DDGVs - Data insights on failure rate vs. Va lve Size Date: Friday. J une 16, 2017 7:45:10 AM 1did - 1agree with some of your points and disagree with others. The failure rate is a surrogate measure to make some relative comparisons. 1agree that this is a demand tailure scenario, but industry does not provide demands (please fix that if you can!) - we only get exposure time. So while I agree with that point, we also should not ignore tens of thousands of years of operating history for these valves (particularly since they are generally demanded on similar frequencies across the industry (and the differences between LaSalle and Columbia are relatively minor when dealing with large data sets like this)). The data includes all failure modes, so the specific failure mode of interest is a portion of the total.

RE: LaSalle SIT Update Just to keep everyone in the loop, we are planning on exiting with LaSalle tomorrow morning. The team reviewed the updated analysis which provided some additional insight on the actual violation . Specifically, the failure analysis performed by an independent vendor combined with the effort done by the Special lnspection Team identified a design flaw in the valve itself (i.e., originally, this was a manufacturing defect by the vendor, but now the vendor has determined it to be a flaw in the design of the valve itself). The vendor

(Flowserve) is in the process of revising the 2013 Part 21 notification to include this design flaw.

The team is exiting with an apparent violation of 10 CFR 50, Criterion 111, "Design Control."

It will be dispositioned under traditional enforcement since no performance deficiency exists (i.e., it was not within the ability of the licensee to foresee and correct) . Specifically, it would be unreasonable for the licensee to have identified th is desi n flaw of the valve from the vendor.

RE: LaSa lle SIT Update The only remaining inspection activities for the LaSalle SIT include inspecting the operability of the Unit 1 High Pressure Core Spray injection valve (i.e. , the opposite unit's valve to the one that failed). The team has gone back and forth with the licensee on the development of information that would provide reasonable assurance of operability. The licensee has continuously been updating their operability based on new information developed/provided by the BWROG, the valve vendor, specialty engineering firms, and an independent lab performing the failure analysis evaluation. The most recent delay was due to the delivery of the failu re analysis report that was completed last Wednesday . The team is currently reviewing/inspecting the report and discussing the issues with the licensee.

The team is scheduled to make their recommendation on the operability of the Unit 1 valve by Wednesday. Depending on the recommendation, we will then schedule the exit meeting. Please Iet me know if you have any questions.

Additionally, for your awareness, headquarters entered into the LIC-504 process (i.e., risk informed decision making procedure developed after Davis Besse) to address the generic implications of the failure. Some actions to be completed include:

- DIRS is working to get an lnformation Notice out within the next few weeks to highlight the failure at LaSalle and similar other failures of this specific type of valve .

- DIRS is evaluating the need for other forms of generic communications (e.g.,

Generic Letter, Bulletin, etc.) to require licensees to respond to the agency.

- Vendor lnspection branch will be going out to the vendor (Flowserve) for an inspection and Region 111 will supplement that inspection with SIT members familiar with the most recent issue.

RE: LaSa lle SIT Updat e Just to keep everyone in the loop, we are planning on exiting with LaSalle tomorrow morning. The team reviewed the updated analysis which provided some additional insight on the actual violation . Specifically, the failure analysis performed by an independent vendor combined with the effort done by the Special lnspection Team identified a design flaw in the valve itself (i.e., originally, this was a manufacturing defect by the vendor, but now the vendor has determined it to be a flaw in the design of the valve itself). The vendor (Flowserve) is in the process of revising the 2013 Part 21 notification to include this design flaw.

The team is exiting with an apparent violation of 10 CFR 50, Criterion 111 , "Design Control."

It will be dispositioned under traditional enforcement since no performance deficiency exists (i.e., it was not within the ability of the licensee to foresee and correct). Specifically, it would be unreasonable for the licensee to have identifi *

• from the vendor.

Subject:

RE: LaSa lle SIT Updat e The only remaining inspection activities for the LaSalle SIT include inspecting the operability of the Unit 1 High Pressure Core Spray injection valve (i.e., the opposite unit's valve to the one that failed). The team has gone back and forth with the licensee on the development of information that would provide reasonable assurance of operability. The

licensee has continuously been updating their operability based on new information developed/provided by the BWROG, the valve vendor, specialty engineering firms, and an independent lab performing the failure analysis evaluation. The most recent delay was due to the delivery of the failure analysis report that was completed last Wednesday. The team is currently reviewing/inspecting the report and discussing the issues with the licensee. The team is scheduled to make their recommendation on the operabil ity of the Unit 1 valve by Wednesday. Depending on the recommendation, we will then schedule the exit meeting. Please Iet me know if you have any questions.

Additionally, for your awareness, headquarters entered into the LIC-504 process (i.e. , risk informed decision making procedure developed after Davis Besse) to address the generic implications of the failure. Some actions to be completed include:

DIRS is working to get an lnformation Notice out within the next few weeks to highlight the failure at LaSalle and sim ilar other failures of this specific type of valve.

DIRS is evaluating the need for other forms of generic communications (e.g.,

Generic Letter, Bulletin, etc.) to require licensees to respond to the agency.

Vendor lnspection branch will be going out to the vendor (Flowserve) for an inspection and Region 111 will supplement that inspection with SIT members familiar with the most recent issue.

Karla, You and Cindy are emailing at the same time. Cindy and Enright talked last night and again this morning. The plan is to shut down Thursday night like you mentioned. We are going to have a quick meeting this morning to "regroup" and discuss how to handle this going forward.

However, this puts us into a difficult position regarding inspection of the valve. Assuming they shutdown Thursday night, 1would guess they would do disassembly of the valve early Friday. Do we have any idea what the licensee has for a timetable for inspecting the valve

/ replacing wedge assembly?

Mark, Tthanks for sharing the plan. It is very comprehensive and contains important milestones and prelim decisions and actions.

With respect to the Comm Plan for the LaSa shutdown. 1think it is best to break out key points and messages. 1 reco111mend the following 1 page format BACKGROUND

• January 4, 2013. TVA initiates a Part 21 notification asa result of a defect discovered in the HPCI inboard containment isolation valve, which is a 1O" Anchor Darling Oouble Oisc Gate Valve (OOGV).

• February 25, 2013. Flowserve submits Part 21 notlfication to identify that Anchor Darl!ng DDGVs" stems were potentially never completely torqued lnto the upper wedge prior to installation. This condition in conjunctfon with high operating torque/thrust on the stem-to-disc connection could lead to wedge pin failure and eventual stem-to-disc separation.

• February 11, 2017. LaSalle Unit 2 HPCS injection valve fails during outage testing.

• April 12, 2017. LaSalle submits LER 50-374/2017-003-00, "High Pressure Core Spray System lnoperable due to lnjection Valve Stem-Disc Separation. "

• April 24, 2017. SIT begins at LaSalle.

o June 9, 2017. SIT exits with LaSalle with one apparent violation for the Unit 2 HPCS valve failure and one URI for the remaining outstanding Part 21 valves .

• June 15, 20 17. NRR/DPR issues IN 2017-03, "Anchor Darling Double Disc Gate Valve Wedge Pin and Stem-Disc Separation Failures. "

Key Messages

• The Special lnspection Team exited the Special lnspection on June 9 and communicated that the team has serious concerns with Exelon's operability evaluation for the LaSalle Unit 1 HPCS valve.

o Exelon has verbally committed to shutting down Untt 1 at LaSalle on Thursday June 22nd _

• The Agency is striving to be deliberate and timely in our decision-making and open and transparent in our communications with Exelon relative to our underfying questions and concerns, while remaining focused on our regulatory mission of ensuring public health and safety.

• The Agency is handling the generic implications of this issue using the LIC 504 process. Key messages from the LIC-504 process include:

o This is not a new issue. Following a similar valve failure at Browns Ferry in 2012, the industry took steps to address the issue. ln light of recent operating experience, including the LaSalle valve failure, both the NRC and industry are taking additlonal actions to resolve the concern .

o These valves are widely used in systems of varying safety significance. However, not all Anchor Darling valves are used in a way that makes them susceptible to this type of failure.

o The NRC has no imrnediate safety concerns because other diverse and redundant systerns could be used to protect the plant if a valve were to fail.

o The NRC plans on holdinga public meeting *in early July to further discuss the operating experience and lndustry actions wlth stakeholders. The NRC will use the informatlon obtained from the public meeting as part of its assessment of the need for additional regulatory actions.

Subject:

Ul HPCS M in Flow Valve Stem Rotation Check AII, 1 would like to provide some information on the U1 HPCS min flow valve stem rotation check that I observed today. This was the first rotation check performed using the "new" methodology (i.e. the metallic measuring device). Please see the first slide of the attached PowerPoint. The longer marks are every 5°, and the others denote 1 °. The pietu re in slide 1 shows additional hardware that was not used during the rotation check.

Slide 2 shows the limited amount of space the licensee had to work with. The valve is approximately 7' up in the air and the stem is almost fully enclosed. The picture on slide 2 shows the small gap the licensee used to install the measuring device, and to mark and observe the stem. There was another small gap on the other side of the valve.

Slide 3 is the best picture I could take of how the measuring device was set up. The licensee marked the stem when the valve was full open, and then again when the valve was full closed.

Slide 4 shows the general space/set up. There was an individual on each side of the valve attempting to assess stem rotation .

This was a full HPCS run, so the min flow valve fully cycled twice - when the pump was started, before the test line valve was opened, and then after the test when the test line valve was closed . The licensee had an individual observing on either side of the valve during the pump start, and then the two individuals swapped positions for the test line valve closure. Neither saw stem rotation.

There was not a lat of room in the area, so I did not have eyes on the stem during the valve movement. The licensee videotaped the rotational checks and we are looking to get a copy.

On June 22, 2017, LaSalle Unit 1 shut down to inspect and repair, as needed, the Pa.Ft 21 applicable parts ar,d thc dc sign 1ssue *ela.tcd to the Unit 1 high pressure core spray (HPCS) injection isolation valve. An NRC special inspection team (SIT) recently completed a special inspection at LaSalle and expressed concerns with the operability of

the Unit 1 HPCS injection isolation valve since it had a similar operating history and environmental conditions to the same failed valve on Unit 2. the failed Unit 2 I IPGS r,jsetioA isolatioA .rsh1e. Multiple Region 3 inspectors will be onsite to observe the diagnostic testing, valve disassembly and the inspection of the valve's components. The NRC plans to use insights from these observations as part of th:: ongoing UC 50-4 activities fti'1fr to determine the need for additional generic communications with the industry.

RE: draft daily note on LaSa lle

Karla, There needs to be a little more context about the broader issue, i.e., connection to SIT, why our interest in this valve issue, and how insights might be used for generic implications.

Make it less tech nical (i.e., the reference to collar slippage is too specific and technical).

draft dai ly note on LaSa lle

Darrell, Please review the draft daily note below and Iet me know of what changes you would like to make. 1 would like to provide this to HQ by 1pm today.

On June 22, 2017, LaSalle Unit 1 shut down to repair the Part 21 applicable parts and the design issue related to collar slippage for the Unit 1 high pressure core spray (HPCS) injection isolation valve. During this four day outage, the licensee will perform as-tound diagnostic valve testing and required surveillance testing in addition to repairing the valve. Multiple Region 3 inspectors will be onsite to observe the diagnostic testing, valve disassembly and the inspection of the valve's components.

Thanks ,

Karla

1would like to provide some information on the U1 HPCS min flow valve stem rotation check that I observed today. This was the first rotation check performed using the "new" methodology (i.e. the metallic measuring device). Please see the first slide of the attached PowerPoint. The longer marks are every 5°, and the others denote 1°. The pietu re in slide 1 shows additional hardware that was not used during the rotation check.

Slide 2 shows the limited amount of space the licensee had to work with. The valve is approximately 7' up in the air and the stem is almost fully enclosed. The pictu re on slide 2 shows the small gap the licensee used to install the measuring device, and to mark and observe the stem. There was another small gap on the other side of the valve.

Slide 3 is the best picture I could take of how the measuring device was set up. The licensee marked the stem wheh the valve was full open, and then again when the valve was full closed.

Slide 4 shows the general space/ set up. There was an individual on each side of the valve attempting to assess stem rotation.

This was a full HPCS run, so the min flow valve fully cycled twice - when the pump was started, before the test line valve was opened, and then after the test when the test line valve was closed . The licensee had an individual observing on either side of the valve during the pump start, and then the two individuals swapped positions for the test line valve closure. Neither saw stem rotation.

There was not a lat of room in the area, so I did not have eyes on the stem during the valve movement. The licensee videotaped the rotational checks and we are looking to get a copy .

Re: Ul HPCS M in Flow Va lve Stem Rotation Check Thank you Chuck and Jackie for the good info. As you can probably imagine, there is a lot of interest from the entire agency on this valve and what will happen in the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. With that being said, please, please communicate early and often on all things related to the LaSalle shutdown and Unit I HPCS valve. Good, bad, delays, anything.

- if there are delays in the stem rotation check, let us know.

- if stem rotation checks are ali SAT, Ietus know.

- if the valve disassembly goes as planned, let us know.

- if the cafeteria switches from French fries to tater tots, especially let me know.

Pictures are great. But the sooner we can get the information, the sooner we can pass it on to all levels of management. I respond just as well to textin so if you just have a quick update, please text me. As a reminder, my number i. (b)(6) I do not care if it is at 10 PM or 2 AM, feel free to text/caU. Everyone is is very mtereste 111 the work that y'all are doing and look forward to heaiing what is going 011 . If you have any questions.... call/text/email me. Thanks!

Thanks, Mark Sent from my iPhone. Please forgive any typos.

RE: LaSalle 1E22 F004 valve diagnostic and stem rotation check Hello Tearu, 1 observed the valve disassemblythis moroing. Due to the tight working conditions, l only got to observe the stem/wedge subassembly inside the valve body aft.er tbe bonnet was removed, but before the subassembly was lifted out of the valve body, r did observe tbe rerno val of the subassembly from a djstance. Overall:

1. The connection appeared tigbt. As seen in the pictures, the coJlar appeared flusb to the wedge. T did not have tbe greatest view, but tbe collar did not appear tilted or cocked like what we saw wüb the U2 HPCS 004 valve.

2. I observed the CMO try to put a feeler gauge between the wedge and collar. He went to tl1e smallest one avai lable which was .0015 (according to what he told me), and could not work itin between. He did attempt to work around the circumference in different locations. From what J could see, and what 1 heard from him, he could not work itin alJ the way. It appears the feeler gauge only (it on the very outside edge between tbe collar and the wedge. This is another iodication that the connection appeared tight.

3. During the removal of the subassembly, the workers usedband chai_nfal\s to remove the subassembly.

Therefore, unlik:e the U2 HPCS 004 valve, the stem/wedge/disc s ubassembly came out of the valve body easily.

Ali of the pictures I took are on the M: Drive. The liok. is below:

l apologize for the quaUty of the pictures. Since most of the pi.ctures were taken from a distance, there's not much to see. Attached to this email however, are the pictures I thought would provide the best information. T pointecl out on tl1e 7th slide that it looks like the stem is not coucentric with the wedge. However, I recognize tbis may just be how the subassembly was manufactured_

The liceosee's oext steps are the following :

l. Decontaminatioo of tbe Subassembly (expect to be done around 7:00am this morning)

2. lnspection and Measuremeuts (expect between 7:00am and 9:00am this morning)

a. The licensee plans on reusing the discs, therefore they will be measuring tbe <liscs_ From what I garhered, tbey would also do a visual of the stem/wedge connection and possibJy try to do the feele.r gauge test again with more room to work wirh.

Therefore. unlike the U2 HPCS 004 valve, the stem/wedge/disc subassembly came out of the valve body easily.

AJI of the pictures I took are on the M: Drive. The link is below; M:\LaSalle Ul HPCS Y-alve Video\UI HPCS IE22-F004 Valve Disassembly<fiJe-L/J\\t1km04\MEDIA\I ,aSalJe%2QU 1%20HPCS%JOValve%20Video\lJl %20HPCS%201 E22-F004%20Va)ve%20Dlsassembly>

1 apologize for the quality of the pictures. Sioce most of the pictures were taken from a distance, tltere' s not much to see. Attached to this email however, are the pictures 1 thought would provide füe best information. T pointed out on the 7th slide tJ1at it looks \ike the steni is not concentric with the wedge. However, J ecognize this may just be bow the subassembly was manufactured.

The licensee's next s teps are tbe followi.ng :

1. DecoJ1tamination of the Subassembly (expect to be done arouncl 7:00am this moming)

2. Inspection and Measnrements (expect between 7:00ai11and 9,00am this morning)

a. The licensee plans on reusing t.he discs, therefore they will be measuting the discs. From what I gat.hered, tbey would also do a visual of the stem/wedge connection and possibly try to do the feeler gm1ge test again with more

room to work with.

3. Ship to offsife laboratory (ET A unknown)

a. Sounds Jike they will be sending the subassembly to Powerlabs. They do not plan on touching the threaded and pinned connection at the site.

lf you have any questions, let me know.

LaSalle J E22 F004 valve diagnostic and stem rotati:on check J've created a new folder 011 the M drive calted LaSalle U I HPCS valve video. 1 moved the stem rotation check video from the U I HPCS min flow valve to this folder and l've down loaded two more videos of the 1E22 F004 stem rotation check.

1gave them some input and recommended that they ma.ke a scribe mark on the measuring device and then count over five degrees and make a long line on the stem. lf the lines cross than you know it was unsat. This is what 1 saw on the closed rotation check. The i11itial movement on the open rotation check was about three degrees but it may have gone to five by the end ofthe stroke. l' d have to watch it a few more times.

1have not seen the diag11ostic traces yet since} was up 011 the platform when they were done, t' ve heard they were similar to the previous traces but that' s second or third hand. l've asked them for traces when tbey are available tonighl Mike, I asked them for the pullout torque. I'll forward it to you when I get it. It was not tru.ly an as found tesr. They had to partiaJJy stroke opeu the valve i11 order to get the OSS sensor on the stem.

RE: laSalle Update Date: Saturday, June 24, 2017 8:46:00 AM Attachments: 1E22-F004 Valve Dissambly 6-24-1 7.pptx To provide an update from this morning and summarize Karla's report from last night:

1. Stem rotation checks and diagnostics were completed late Friday afternoon. Chuck was onsite for the rotations and observed about 6 and 3 degrees of rotation on the close and open strokes, respectively (the BWROG Topic Report recommends less than 5 degree rotation). lnitial reports from the traces did not identify any type of abnormalities. They have sent us the traces and will also be sending to their vendor (Kalsi Engineering) for further analysis.

2. Valve disassembly was completed this morning and Lionel was onsite to observe (pictures are attached). From the initial reports, the subassembly remained connected . l.e., the stem-to-wedge connection remained threaded. The condition of the threads and the wedge pin itself is still unknown. Since everything was still intact, they will be sending it to their Powerlabs as they found it for further evaluation (i.e., they are not going to try and disassemble the valve any further on site). This means that there is very little more that we are going to learn this weekend.

Additional pictures can be found here: M:\LaSalle U1 HPCS Valve Video\U1 HPCS 1E22-F004 Valve Disassembly.

The site VP did have a quick discussion with Lionel before he left this morning.

Specifically, he wanted to ensure that we (the NRC) have received all of the appropriate information / documentation needed. His initial take on the condition of the valve was that it passed ali diagnostic checks (i.e., the rotation checks and traces) and that it was fully intact. He was also curious to know what we would be discussing in the upcoming Public Meeting (currently scheduled at Headquarters for Thursday). Karla and I will coordinate with the site and ensure we provide a clear message for the Public Meeting.

lf anyone has any questions, comments , or concerns, please Iet me know.

3. Valve internai inspection will be observed by Jamie and is scheduled to begin at 1500 Saturday afternoon.

As with most outage schedules, 1expect delays to occur and these times to shift; however, Karla and I have discussed with the team to communicate early and often. As a result, we will be ensuring that the Regional leadership team is kept informed as the outage progresses (1will also be reaching out to the LIC 504 team at headquarters). lf anyone has any questions, comments, or concerns, please Iet m kn w . 1will checking my ernail often and will also be accessible via my celi phone (b)(6)

LaSalle Unit 1 status Good morning Jeremy, 1just received a skype message from Theresa Clark so I wanted to update you on the status of LaSalle Unit 1. Over the weekend we had several inspectors at the site monitoring the HPCS injection valve activities. During the stem rotation checks , we observed the stem rotating between 3 and a little over 5 degrees. The BWROG wants five degrees or less.

Last night, we received the licensee's formai review of the valve diagnostic traces. 1believe these traces will be reviewed within Region 111 and NRR this week.

Once the valve was opened up, the disk and wedge were still connected . Since they were connected , there wasn't much we could observe regarding actual thread condition. The licensee is shipping the stem and wedge to Exelon Powerlabs for additional review. The shipping should occur today. The new stem installed in the HPCS injection valve has a collar that is integral to the stem so the new stem/wedge are not susceptible to the design issue identified during the SIT.

Let me know it you need anything else, Karla Karla Stoedter, Chief Region 11 1Division of Reactor Projects - Branch 1 630-829-9731 (office)

Chuck was onsite for the rotations and observed about 6 and 3 degrees of rotation on the close and open strokes, respectively (the BWROG Topic Report recommends less than 5 degree rotation). lnitial reports from the traces did not identify any type of abnormalities. They have sent us the traces and will also be sending to their vendor (Kalsi Engineering) for further analysis.

2. Valve disassembly was completed this morning and Lionel was onsite to observe (pictures are attached). From the initial reports, the subassembly remained connected. l.e., the stem-to-wedge connection remained threaded. The condition of the threads and the wedge pin itself is stili unknown. Since everything was stili intact, they will be sending it to their Powerlabs as they found it for further evaluation (i.e., they are not going to try and disassemble the valve any further on site). This means that there is very little more that we are going to learn this weekend.

Additional pictures can be found here: M:\LaSalle U1 HPCS Valve Vjdeo\U1 HPCS 1E22-F004 Valve Disassembly.

The site VP did have a quick discussion with Lionel before he left th is morning.

Specifically, he wanted to ensure that we (the NRC) have received ali of the appropriate information / documentation needed. His initial take on the condition of the valve was that it passed ali diagnostic checks (i.e., the rotation checks and traces) and that it was fully intact. He was also curious to know what we would be discussing in the upcoming Public Meeting (currently scheduled at Headquarters for Thursday). Karla and I will coordinate with the site and ensure we provide a clear message for the Public Meeting.

lf anyone has any questions, comments , or concerns, please Iet me know.

Three specific milestones have been selected to ensure we have inspector oversight and awareness:

1 . lnitial stem rotation checks will be observed by Chuck and are currently scheduled to be performed at 1500 this afternoon.

2. lnitial valve disassembly will be observed by Lienei and is scheduled to begin at 0600 Saturday morning (scheduled to be completed by 1100).

3 . Valve internai inspection will be observed by Jamie and is scheduled to beg in at 1500 Saturday afternoon.

As with most outage schedules, 1expect delays to occur and these times to shift; however, Karla and I have discussed with the team to communicate early and often. As a result, we will be ensuring that the Regional leadership team is kept informed as the outage progresses (1will also be reaching out to the LIC 504 team at headquarters). lf anyone has any questions, comments, or concerns, please Iet me know. 1will be checking my ernail often and will also be accessible via my cell phone (b)(6l Thank You, Mark Jeffers Branch Chief I RIII DRS EB2 1x9798

PB Part 21 - You will find t his interesting . . .

So Point Beach MOV engineer thinks that the recommended torque values provided in the flow serve table is what pre-torque should be. They add that pre-torque value to the wedge pin structural value and as long as it is less t han the operational max value they said they are ok.

They totally missed it and had the BWR owner's group guidance.

lnteresting enough. PB torque values are significant lower than LaSalle. For a 1O

pressure class 1500, they maximum allowable torque in the closed direction was 657 ft-lbs.

RE: Kalsi Analysis Date:              Wednesday, June 28, 2017 7:44:49 AM Thanks Chuck. 1 find it interesting that the reworked valve doesn't exhibit a smooth stem decompression region in the thrust and torque traces and that Kalsi Engineering making the statement that "The criteria for evaluating the stem thrust decompression region as an indication of possible loss of stem-to-upper wedge connection integrity will need to be refined based on the 1E22-F004 diagnostic data." The stem decompression region was where the 2E22-F004 valve had the anomalies in 2015 which led LaSalle to believe that this was the smoking gun pointing to an issue with the valve internais integrity. 1 always thought that the 2015 2E22-F004 anomalies were due to changes in the friction factors and did not point to valve problems. The as-left traces on the reworked valve I would consider normai. The less than smooth transition in the stem decompression region is most likely due to the new packing set and new stem to stem nut interface.

1updatad Slide 4 to amphasiza that tha failura machanism is dua to a dasign flaw. Wa can discuss that Flowserve is expacting to updata their Part 21.

Slida 5 seams out of placa. ls this somathing that wa can just discuss on Slide 2 and just daleta Slide 5? (l.a. , Background is in Fabruary 2013 Flowserve initiatad Part 21 , in April 2013 BWROG initiated Topic Report, and then in February 2017 LaSalle axperianced HPCS injection valve failura.)

1am a little confused by Slide 7 regarding tha Risk Assessment. 1know you are going to discuss in detail ; howevar, 1am unsure how you were able to detarmine these numbers if wa do not know all of the details of the specific valves (a.g., system that it is in , safety function, etc.).

1added soma high Ievel points to Slida 8 to provide a status update of tha SIT and tha most racent Unit 1 shutdown.

1also added soma point to Slida 8 on tha ganaric status updata.

o            For your awaraness. It looks lika getting the lnformation Notice out early was beneficial just to get the issua aut for everyone's awareness. The Point Beach DBAI team (currently in its first waak onsita this weak) salectad the Flowsarve Part 21 notification as one of their OpE samples and identifiad that the licensaa had misinterpreted the original Flowserve Part 21 notification and are only now undarstanding the issua. Furthar convarsations from the DBAI team and the licansae indicate that NextERA and FPL may have generically misinterpreted the original Part 21 across their fleet. Currently, the team has not identified any operability concerns, but the licensee is taking actions and are now putting all of the identified components into their CAP as non-conforming.

RE: Lab info on LaSalle HPCS va lve Date:              Thursday, June 29, 2017 9:28:55 AM Brian You are correct, the lab could not separate the stem from the wedge and thus had to cut the components apart. This would tend to be consistent with the licensee's stroking of the valve just prior to its disassembly. The licensee completing its stroking of the valve in the closed direction, thus the closed the valve with some 240 kips of force in the closed direction with nothing to stop the stem from rotating into the wedge to the maximum extent possible until the cut out switch would stop it.

Brian -

Thanks very much for the quick review and comments - 1made a few changes to the slides:

* Slide 5 - added a little more context to capture the "how many valves, in how many applications" but also note that we don't have complete information on this yet. Also added a few sub-bullets that the diagnostics recommended by the BWROG cannot reliably detect wedge pin breakage and MOV traces are tough to interpret.

* Split up Slide 8 on current status to add a couple of pictures from the Unit 1 HPCS valve failure evaluation.

* Will speak to what we learned at the public meeting today Kevin From: Hollan, Brian Sent: Thursday, June 29, 2017 6:54 AM To: Coyne, Kevin <Kevin.Coyne@nrc.gov>; McDermott, Brian <Brian.McDermott@nrc.gov>

RE: Slides for QSAM on AD valves Great slides. This will be the highlight of the 4 items we will be hearing about.

1am in Jul 5 thru 7th at noon.

So look forward to this presentation.

Add a slide on latest valve Add or talk to Thurs public meeting thoughts Only skimmed the slides, but wasn't sure I saw "how many valves, in how many applications" are out there.

Also - the difficulty we have in "recognizing this condition" without getting into the valve (e.g. that diagnostics and traces may not teli the story)

Vance: effers, Mark; Robbins, iohn subject:        stem collar Date:           Thu rsday, June 29, 2017 7 :01 :06 PM Hi Lio, 1think it should be cleared up whether the collar on the stem is shrunk fit or press fit since 1 remember shrunk flt but it was also asserted to be a pressfit. 1wasn 't on the conference call today so I don't know if it was called a press fit on the conference call today. Could you please confirm for me what kind a fit it is. Unfortunately, 1will not be in on Friday so I have to send this email.

1think it is shrunk fit because I thought I remembered seeing shrunkfit in the MPR report and so I checked the MPR report, and it says it's a shrunk fit in many places, e.g., section 1.2.1., Valve Description, states: "For this configuration, the stem collar had been shrunk fit onto the stem. And "Bearing of the shrunk fit stem collar against the upper wedge maintains pre-load in the threaded connection".

Also the MPR report, states in section 6.0 Engineering Evaluations: "The valve design includes a shrunk fit stem collar.

Also the Conclusions on page 66 state: "all the rudai closing forces were directly applied to the shrunk fit collar.

Please Iet me know it you confirm if it is a shrunk fit.

: Thanks, Gerry.

Background
* On February 11, the Unit 2 High       LaSalle County Generating Station Pressure Core Spray (HPCS)

Discharge Valve experienced a stem-disc separation failure during a system fill and vent.

* Although the valve indicated open, there was no air or water flowing through the valve.

Other Context

* lssue affects over 40 plant sites (BWRs and PWRs)

- Valves are used in risk significant applications {ECCS, ESW, CCW)

- We currently do not have a complete population inventory of all A/D DDGVs in service

* Flowserve Part 21 - # 2013-09-00, Wedge Pin Failure in Anchor Darling Motor Operated Double Disc Gate Valve (ADAMS ML13064A012).

* BWROG Guidance - BWROG-TP-13-006, "Recommendations to Resolve Flowserve 10 CFR Part 21 Notification Affecting Anchor Darling double Disc Gate Valve Wedge Pin Failures."

-  Recommended testing cannot reliably detect degraded valve {e.g.,

failed wedge pin)

-  MOV diagnostics {traces) difficult to interpret U.S.NRC
