SUBJECT:
SUMMARY
OF THE SEMI-ANNUAL SENIOR MANAGEMENT I'
_ MEETING WITH THE WESTINGHOUSE OWNERS GROUP (WOG)
TO DISCUSS ITEMS OF MUTUAL INTEREST The subject meeting was held at the NRC offices in Rockville, Maryland on March 31,1998, between representatives of the WOG and the Office of Nuclear Reactor Regulation (NRR) staff.
The purpose of the semi-annual senior management meeting is to encourage communication between the NRR management and the WOG, discuss emerging issues or concerns, and i
provide a status of NRR and WOG activities.
Mr. Sam Collins, the Director of NRR, provided opening remarks that consisted of a status update of activities at the NRC. Mr. Collins addressed license renewal, AP-600, resources and l
the budgeting / planning cycle, priorities, including a discussion of the review of the priority -
l-system to try to address both " customer" and " safety" topical reports, the regulatory information
. conference, the licensee assessment process, the transfer of rulemaking activities to NRR, emerging technical issues, the effect of deregulation on the industry, decommissioning l
activities, and risk-informed regulation.
The WOG presentation began with a summary of the Steering Committee members and a L
discussion of the formation of the WOG Executive Management Group.' This new group will serve as an executive interface and strategic planning body for the WOG.
Although the WOG works on a large number of issues at any one time, the WOG specifically addressed eight technical areas at the meeting: fuel rod intemal pressure, incomplete rod insertion, severe accident management, baffle barrel bolting (BBB) program, part-length control rod drive mechanism (CRDM) program, risk-informed probabilistic risk assessment (PRA) 9y//
j:
applications, life cycle management / license renewal program, and the Year 2000 issues.
f' These issues have been or are of current interest to the NRC and are discussed briefly below.
The WOG stated that the fuel rod design model being developed to address the fuel rod internal -
pressure issue is still on track for completion in July 1998. After that work is completed, specific k
plant evaluations will no longer be necessary. To date, all plants meet 10 CFR 50.46 limits.
The WOG will continue to follow the issue until resolution.

April 3, 1998 The WOG outlined the recommendations it made to its members regarding burn-up threshold values and its long range plan for the incomplete rod insertion issue. The WOG plans to i
analyze additional drag test data to possibly modify the threshold values in the future. The l
NRC staff stated that we thought the efforts in this area were proceeding as expected and desired.
The WOG discussed the severe accident management guidelines (SAMG). In a January 1998 letter, NRC provided comments on the NEl positions contained in NEl 91-04, Rev.1, " Severe Accident issue Closure Guidelines" and the 1997 NEl letter. The WOG stated these comments appear contrary to previous staff positions. The WOG discussed what they believe are three -
major differences between the NRC and industry positions. After discussing the concerns, the staff stated that it felt these differences may be resolved through clarification and that the NRC and industry should be able to work through the issues.
The BBB program was discussed at length. The WOG has submitted a number of topical reports to the NRC for review and approval to define the licensing basis on the BBB distribution.
l The industry has developed a methodology to replace a certain number of bolts versus i
. replacement of all the bolts should any bolts be found in a degraded condition. The WOG discussed the schedule for NRC approval of the topical reports that would support the planned inspection schedule, which is scheduled to begin this fall, in a phone call several weeks ago, the staff informed the WOG that it would be difficult to meet the schedule proposed by the WOG. The staff suggested that the WOG and NRC try to develop an alternate plan. A meeting is scheduled for April 8 to specifically discuss the BBB program and it was suggested that a l
. discussion be held at that meeting regarding schedule and alternate plans.
The WOG provided the history of the part length CRDM program, including the initiation of the
- Regulatory Response Group (RRG) to address short-term actions. The WOG informed the L
NRC that a new subgroup has been formed to address the part length CRDM program. The RRG plans to work with the new subgroup and then closeout RRG activities. A meeting will be scheduled in the near future between the RRG, the new subgroup members, and the NRC to l
discuss the longer range plan.
l The WOG outlined the risk-informed PRA applications and discussed WOG expectations with regard to the NRC activities in order to meet certain refueling outage cycles. The WOG indicated a number of plants are interested in risk-informed applications. The WOG will provide L
the staff with a count of how many submittals to expect in this area. The staff stated it is difficult L
for the staff to meet all these demands. The staffs expectation is that once the lead plant is l
complete, an ensuing code case and rule change would obviate the need for NRC review and approval of these items on a plant specific basis.

l T.. Essig 3-April 3, 1998 The WOG discussed the life cycle management and license renewal program. The WOG has five generic topical reports under review by the NRC. The staff informed the WOG of the lack of resources to address all the generic topicals and the plant specific applications that are j
expected in the near future. The staff will, however, continue to work on topicals that are or will be referenced in a plant specific application.
The WOG provided the staff an update of the Year 2000 issue. A subgroup has been formed l
and will be meeting in the near future. A workshop is planned which will include a wide variety of participants, including some outside the nuclear industry. The staff requested whether they could attend the workshop. The WOG will provide a response to the staff.
l A brief discussion was held on the overall status of WCAP reviews. The WOG was informed that generally the staff prefers a lead plant application be submitted in support of the review and approval of a topical report.

Utilize bumup threshold values as part of the reload design analysis
- For fuel assemblies above the threshold values,use a mechanical model, such a GROWBOW, to determine susceptibility to IRI
- Perform rod drop and drog test at EOC for all fuel assemblies that exceed the threshold values.
- If the mechanical model indicates a susceptibility to IRI, then additional analysis or rod drop testing should be performed Compile a list of fuel assemblies with burnups greater than 50,000 MWD /MTU. Sclected assemblies will be identified for drag testing to enhance the current data base and possibly increase the thresicld values.

Sevent Accident Management--
- The Bullor differences betweenNRC & industry positions for PWRs are:
- Industry: SAMO is not within the scope of operator licensing examinations since it is outside the plant's licensing basis
+ NRC: SAMO is testable
- Industry: SAMG training should be developed using the principles of a Systems Approach to Training, but not the pedigree required for training topics within the plant's licensing basis
- NRC: wants the pedigree also
+ Industry: 10CFR 50.59 is not applicable to SAMO (with a few minor exceptions)
= NRC: 50.59 screening should be done on SAMO nm seatcim u

April 3, 1998 MEMORANDUM FOR: Thomas H. Essig, Acting Chief Generic lasues and Environmental Projects Branch Division of Reactor Program Man'agement Office of Nuclear Reactor Regulation FROM:
Claudia M. Craig, Senior Project Manager Olt([jc,
%p Generic lasues and Environmental Projects Branch T
Division of Reactor Program Management b
Office of Nuclear Reactor Regulation
SUBJECT:
SUMMARY
OF THE SEMI-ANNUAL SENIOR MANAGEMENT MEETING WITH THE WESTINGHOUSE OWNERS GROUP (WOG)
.TO DISCUSS ITEMS OF MUTUAL INTEREST The subject meeting v/as held at the NRC offices in Rockville, Maryland on March 31,1998, between representathes of the WOG and the Office of Nuclear Reactor Regulation (NRR) staff.
The purpose of the somi-annual senior management meeting is to encourage communication between the NRR ms nagement and the WOG, discuss emerging issues or concems, and provide a status of N1'tR and WOG activities.
Mr. Sam Collins, the Director of NRR, provided opening remarks that consisted of a status update of activities at the NRC. Mr. Collins addressed license renewal, AP-600, resources and the budgeting /planr.ing cycle, priorities, including a discussion of the review of the priority system to try to add ess both " customer" and " safety" topical reports, the regulatory.information conference, the licensee assessment process, the transfer of rulemaking activities to NRR, emerging technical issues, the effect of deregulation on the industry, decommissioning activities, and risk-informed regulation.
. The WOG presentation began with a summary of the Steering Committee members and a
- discussion of the formation of the WOG Executive Management Group. This new group will serve as an executive interface and strategic planning body for the WOG.
Although the WOG works on a large number of issues at any one time, the WOG specifically addressed eight technical areas at the meeting: fuel rod intemal pressure, incomplete rod insertion, severe accident management, baffle barrel bolting (BBB) program, part-length ~ control
. rod drive mechanism (CRDM) program, risk-informed probabilistic risk assessment (PRA) applications, life cycle management / license renewal program, and the' Year 2000 issues.
These issues have been or are of current interest to the NRC and are discussed briefly below.
L The WOG stated that the fuel rod design model being developed to address the fuel rod intemat
- pressure issue is still on track for completion in July 1998. After that work is completed, specific plant evaluations will no longer be necessary. To date, all plants meet 10 CFR 50.46 limits.
The WOG will continue to follow the issue until resolution.
f ll e s, 1
T. Essig
-2 April 3, 1998 The WOG outlined the recommendations it made to its members regarding burn-up threshold values and its long range plan for the incomplete rod insertion issue. The WOG plans to analyze additional drag test data to possibly modify the threshold values in the future. The NRC staff stated that we thought the efforts in this area were proceeding as expected and desired.
The WOG discussed the severe accident management guidelines (SAMG). In a January 1998 letter, NRC provided comments on the NEl positions contained in NEl 91-04, Rev.1, " Severe Accident issue Closure Guidelines" and the 1997 NElletter. The WOG stated these comments appear contrary to previous staff positions. The WOG discussed what they believe are three major differences between the NRC and industry positions. After discussing the concerns, the staff stated that it felt these differences may be resolved through clarification and that the NRC and industry should be able to work through the issues.
The BBB program was discussed at length. The WOG has submitted a number of topical reports to the NRC for review and approval to define the licensing basis on the BBB distribution.
The industry has developed a methodology to replace a certain number of bolts versus replacement of all the bolts should any bolts be found in a degraded condition. The WOG discussed the schedule for NRC approval of the topical reports that would support the planned inspection schedule, which is scheduled to begin this fall. In a phone call several weeks ago, the staff informed the WOG that it would be difficult to meet the schedule proposed by the f
WOG. The staff suggested that the WOG and NRC try to develop an alternate plan. A meeting l
is scheduled for April 8 to specifically discuss the BBB program and it was suggested that a discussion be held at that meeting regarding schedule and alternate plans.
I The WOG provided the history of the part length CRDM program, including the initiation of the Regulatory Response Group (RRG) to address short-term actions. The WOG informed the NRC that a new subgroup has been formed to address the part length CRDM program. The RRG plans to work with the new subgroup and then closecut RRG activities. A meeting will be scheduled in the near future between the RRG, the new subgroup members, and the NRC to discuss the longer range plan.
The WOG outlined the risk-informed PRA applications and discussed WOG expectations with regard to the NRC activities in order to meet certain refueling outage cycles. The WOG indicated a number of plants are interested in risk-informed applications. The WOG will provide the staff with a count of how many submittals to expect in this area. The staff stated it is difficult for the staff to meet all these demands. The staffs expectation is that once the lead plant is complete, an ensuing code case and rule change would obviate the need for NRC review and
{
approval of these items on a plant specific basis.

l-The WOG discussed the life cyc!e management and license renewal program. The WOG has five generic topical reports under review by the NRC. The staff informed the WOG of the lack of resources to address all the generic topicals and the plant specific applications that are expected in the near future. The staff will, however, continue to work on topicals that are or will be refererred in a plant specific application.
The WOG provided the staff an update of the Year 2000 issue. A subgroup has been formed and will be meeting in the near future. A workshop is planned which will include a wide variety -
l of participants, including some outside the nuclear industry. The staff requested whether they
. could attend the workshop. The WOG will provide a response _to the staff.
A brief discussion was held on the overall status of WCAP reviews. The WOG was informed that generally the staff prefers a lead plant application be submitted in support of the review and approval of a topical report.

- Westinghouse Evaluation ofNew More Conservative Corrosion Model All aspects of plant safety analyses remain bounding except for:
=
- potential to exceed no gap re-opening design limit
- possibility of exceeding 17% oxidation limit with gap re-opening Gap re-opening does not lead to fuel failures during normal operation Plants in Compliance
- Plants in first half of operating cycle or retuming from an outage not expected to have gap re-opening
- All plants predicted to have gap re-opening,but which have pre-oxidation < 12%

Incomplete RodInsertion
- WOO Recommendations to Membership Regarding Incomplete Rod Insertion Utilize burnup threshold values as part of the reload design analysis For fuel assemblics above the threshold values, use a mechanical model, such as OROWBOW, to determine susceptibility to IRI Perform rod drop and drag test at EOC for all fuel assemblies that exceed the threshold values.
If the mechanical model indicates a susceptibility to IRI, then additional analysis or rod drop testing should be performed Compile a list of fuel assemblics with burnups greater than 50,000 a
MWD /MTU. Selected assemblics will be identified for drag testing to enhance the current data base and possibly increase the threshold values.

- NEI 91-04, Rev. I Severe Accident Issue Closure Guidelines & NElletter July, 1997 contained industry positions for SAMO.
- Based on the original intent when the utility executives voted in late 1994 to make this a binding requirement
- The NEI clarifications were generally consistent with our knowledge ofNRC expectations in late 1994 letter
- NRC January 1998 letter provided comments on the NEI positions j
- NRC comments appear contrary to previous *1994* positions i
i M148 SENRCLFFT 18 j
WESTINGHOUSE OWNERS GROUPS WOG / NRC INFORMATION MEETING MARCH 31,1998 II. WOG PRESEifrATIONS Severe AccidentManagement w
- The malor differences between NRC & industry positions for PWRs are:
- Industry: SAMO is not within the scope of operator licensing examinations since it is outside the plant's licensing basis
- NRC: SAMO is testable
- Industry: SAMO training should be developed using the principles of a Systems Approach to Training, but not the pedigree required for training topics within the plant's licensing basis
- NRC: wants the pedigree also
- Industry: 10CFR 50.59 is not applicable to SAMO (with a few minor exceptions)
- NRC: 50.59 screening should be done on SAMO l

Baffle BarrelBolting (BBB) Program
=
- WOO is continuing technical update meetings with the NRC on status of the BBB program analyses, site inspection / replacement activities and requested review schedules:
- Recent technical review meeting conducted 2/2&98 focused on:
- status ofWOO/NRC submittals review of planned WOO /NRC submittals a
presentation of 2-loop risk. informed evaluation nesults
- Incremental core damage frequency contribution associated with degraded baffle barrel bolts: 4.9E-07
- Based on these results,it is appropriate to treat potential baffle-barrel bolt degradation as an aging management issue.

+ The Part Length CRDM IIousing Craeang At Prairie Island Unit 2 originated during the fabrication process and was not service induced
+ The Prairie Island Unit 2 crack i. a uneven in depth,leeding to detectable leakage
+ Part Length CRDM IIousing failure is bounded by existing safety analyses l
- Core Damas: risk is not increased by the potential presence of a flaw in a Part Length CRDM housing
+ Therefore, plants can continue to operate without adversely afTecting public health and safety while this issue is being addressed 1

Part Length CRDM Program --
- Per NRC request, WOG RRG recommended to membership that the affected utilities consider the following voluntary actions:
+ For operating plants, individual utilities should docket their plan to address this issue within 30 days For plants currently in refueling or cold shutdown, individual utilities shculd docket their plan to address this issue within 30 days, or prior to startup
- For compensatory actions until the issue is resolved, those units continuing to operate with part length CRDM housings installed are requested to increase reactor coolant system (RCS) leakage monitoring awareness and include this in their individual response letter
- Continuing Activities
- Subgroup being formed to further develop and implement an integrated plan to address issue, met 3/2/98 & 3/23/18 and will meet again 4n/98
