SUMMARY
OF SEMI-ANNUAL MEETING HELD ON MAY 13,1999 WITH COMBUSTION ENGINEERING OWNERS GROUP EXECUTIVE COMMITTEE On May 13,1999, the staff held a public meeting with Combustion Engineering Owners Group (CEOG) Executive Committee at Nuclear Regulatory Commission (NRC) headquarters in Rockville, Maryland. Members of public were also present for this meeting. The purpose of this meeting was to exchange information and to provide a forum for discussion topics related to both NRC and CEOG activities. Attachment i lists meeting participants. Attachment 2 provides a set of slides presented by CEOG, and Attachment 3 provides a set of slides presented by NRC staff during the meeting.
Mr. Sam Collins (NRC) provided opening remarks and an overview of NRC activities for the next six months. He discussed the new responsibiiities of various organizations due to the recent NRC reorganization effort. He provided an update on revisions to the Maintenance Rule and noted that decommissioning activities will be managed by Brian Sheron. This is a very important area for the NRC and therefore the regulations need clarity and less reliance on exemptions. He noted several current activities, including: license renewal, improved standard technical specifications, events assessment, maintenance rule, and operator licensing. On the issue of license renewal, current NRC budget can support two plants in FY1999; and four plants per year for FY2000 and beyond.
Mr. Brian Sheron provided an update on several topics. The NRC is following closely the activities of the Nuclear Energy Institute (NEI) Licensing Action Task Force. The average time for licensing action is now down to about five months (it used to be greater that eight months; some greater than three years). He noted a goal of no licensing actions greater than 1 year.
Related issues include timely response to Request for Additional Information (RAI); acceptance
- )
review; meetings and phone calls to resolve issues is being encouraged. He stated that there
/
is no requirement implicit or explicit for the staff to issue RAls. By 2000, the current backlog is expected to be cleared out.
Mr. Jim Levine thanked the NRC Senior Management for supporting these meetings with the CEOG. NRC senior management's supports to these meetings provide good feedback to the 9906180149 990608 PDR TOPRP ENVC-E en, m v no me, e w,

- June 8, 1999 CEOG and its members on areas that need focused attention and allow the CEOG an opportunity to highlight its accomplishments.
Mr. Ralph Phelps (Omaha Public Power District, OPPD) updated NRC senior management on CEOG activities. He also reviewed the current status of NRC review and approval of CEOG topical reports. He highlighted the emerging topic of self assessments.
Mr. Paul Hijeck (ABB) highlighted a number of CEOG activities which directly support self assessments.1 These activities include the CEOG Safe Shutdown Functional Analysis (SSFA),
Probabilistic Risk Assessment (PRA) Certification Process, Steam Generator Program Self q
Assessments, Outage Preparations Readiness Reviews and Outage Readiness Reviews.
d Mr. Ray Schneider (ABB) provided an update on the project to eliminate the post accident sampling system. A topical report was submitted on May 5,1999. The NRC indicated that they plan to support a 90 day review and approval of the report.
Mr. Ken Scarola (ABB) provided an update on the licensing review of the Common Q Topical Reports and Appendicos by the NRC.

above required commitments; relied on existing o
l programs, e.g., App. B ctOc ca.cuev. commm..
u y1999
Voluntary Industry Initiatives e NRC discussed Voluntary Industry Initiatives at the 11/98 Executive /NRC meeting
. means to reduce regulatory burden and costs e NRC requested input
. How do you (CEOG members) provide a level of assurance of implementation of voluntary initiatives 7 e Action item to respond to NRC Senior Management at 5/99 meeting i
CEOG Executive Committee May 1939 l
l 1
Voluntary Industry Iriitiatives e CEOG recommends the following approach
. commitments only through formal correspondence by licensee to NRC
= licensee may use peer reviews /self assessments to i
support effective implementation of an initiative
- inform NRC of peer review
. NRC can use existing programs for inspection and enforcement as they deem appropriate for the initiative CEOG Executive Commmee May 1999 I

I, Purpose and Method e Purpose
. Regulatory approval for CEOG plants to eliminate PASS requirements from licensing basis e Methcd
. CEOG Ucensees will request change to eliminate PASS via joint application report
. ANO-2 and SONGS-2,3 are lead plants e Schedule
. CEOG licensees plan to implement by 4099 CEOG Executve Comeruttee May 1999 Basis for Joint Application Report e Demonstrate to NRC that PASS is not needed for effective post-accident management:
. Data from PASS provides no added benefit to accident management and emergency preparedness
. Altemate systems and means exist to collect post-accident data, where necessary
. Attemate analyses may be effectively substituted for post-accident data
. PASS use may be detrimental to plant safety.

Background
l e CEOG/NRC Topic in November 1998
. Discussed technical rationale for PASS elimination
. NRC could not commit to proposed CEOG review schedule until further EP discussions ensued with Staff
. NRC agreed to and encouraged further communication e NEl meeting with NRC in December 1998
. Discussed NRC concems regarding emergency planning e ABB/CEOG have attended two NRC meetings in 1Q99 to discuss Wolf Creek application
. RAls useful for ABB to recognize similanties and differences in Wolf Creek and CEOG initiatives l
CEoG Execugve Commmee May 1999
-\\
i Project Milestones e Clarified EP concems with NRC (3/1/99) e Reviewed applicability of WOG submittals and submitted draft CEOG joint application report to CEOG (4/15/99) e Submitted formaljoint application report to NRC (5/5/99) j
. ANO has volunteered to be lead plant
. Request 90 day NRC review and final SER e Meet with NRC to review joint application report -

l Benefits of PASS Elimination e Cost benefits:
. Yearly maintenance savings of about $80 K per year per unit
. Short term capital cost savings of $150-800K for some units
. Integrated lifetime savings in excess of $20M for CEOG plants e Safety benefits:
. Use of PASS results in significant post accident doses (2 REM in CR based on SCE)
. PASS usage may limit access to certain AB rooms
. Limitations on sampling process (timing, location, ability to establish true containment and/or RCS readings) may lead to incorrect operator diagnosis of EP action CEoG Executive Committee May 1999 Cost-Benefit Basis for PASS Elimination P4h4 Prepreted Per ben Dese,y DeM Coeu and Amewspesed bhen Isre Capital Costa PLANT 04M Costs Ashsspeeed $ hen Tere Capual Coats for Upsrede**

O NRC Concerns e Boron Sampling Concern:
. Ensure removal of PASS will not adversely impact EOPs
. CEOG position recommends downgrading the boron sample action in the EOPs from required to a recommended action when practical
. Ensure capab;lity of NSS to extend into low levels of core damage (Non-LOCA credible events)
. Demonstrate that EOPs are robust and correct actions can be taken without sampling (SGTR backflow issue, SBO, LOCA)
. Identify backup capability to boron sampling exists via startup monitors, calculations, analytical methods CEoG Executive Committee May 1999 7
NRC Concerns e Radioisotope Sampling:
. NRC concem that removal of PASS capability will degrade plant's ability to perform CDA and EP e CDAM lssue:
. Demonstrate that the key elements and intent of the CDA are being carried out in SAMG.
. Demonstrate that the current CEOG CDA is not degraded by eliminating:
- RCS dissolved hydrogen sample
- RCS and containment radio-isotope sample.
Ceco Executive Commmee May 1999

l l
NRC Concerns e CEOG position is that containment atmosphere radioisotope assessment is:
. difficult to interpret and potentially misleading
. timing of sample. consequences of containment failure and deposition and re-evolution issues
. addresses only a few of the severe accident scenarios (primanly the ones with low risk -intact containment) e Proposal to address NRC EP issue of projecting / correcting release estimates by committing to use 1-131 capable detectors in site surveys, e Improves PARS for all accident scenarios
. No second guessing on what gets out due to filtering via leak paths, settling, clogging etc.
CEoG Execuove Committee Mey 1999 NRC Concerns e CEOG position on RCS radionuclide sampling is that while it is nominally in the EAL ALERT level:
. will never be the first indication that an ALERT status exists
. attemative measures of ALERT status may be used in place of the RCS sample.
o If necessary to confirm low levels of fuel damage
(< ALERT levels) the NSS may be used with some acceptable time delay (24 or more hours)
