9/10/79 OUTLINE OF SUF14ARY OF STATUS OF B&O TASK FORCE REVIEW OF WESTINGHOUSE-DESIGNED OPERATING PLANTS A.
INTRODUCTION 1.
Bulletin Review 2.
Generic Review of W-designed PWRs B.
BULLETIN REVIEW l.
Background
I&E Bulletins79-06A and 79-06A, Rdvision 1, issued in mid-April
, Licensee re'sponses received late-April - early-May
< Review Group fcrmed to review responses S. Varga (DPM)
M. Willia.s (DPM)
K. Mahan (DPM)
N. Wagner (OSS)
C. Trammell (00R)
R. Woodruff (I&E)
Review Group received responses; prepared draft safety evaluations e
and appropriate requests for additional information - early-June OR PMs faxed draft SEs and RAIs to licensees - early-June.
. Licensees provided supplemental responses - late-June - mid-July.
- New review group formed.- mid-June K. Mahan (B&O)
N. Wagner (B&O)
P. O'Reilly (B&O)
C. Trammell (D0R)
Cognizant OR PM e.Because of startup requirements, 11 plants received special review mid-June - late-July Acceptable responses required to certain Bulletin items before.startup.
Licensees revised their responses accordingly.
- Review of licensees' responses, as supplemented by OR PM, in cooperation from task group.early-August - early-September
.Oraft safety evaluation updated.
Necessary RAI'sisent to licensee via letter.
2..
Current Status OR PMs updating safety evaluation.
. Items 2, 7(b), and 12 are being resolved with E Owners' Group.
Item 7(c) superseded by IES79-06C.
OLB needs regarding status for examination purposes.
3.
What's Coming i Resolution of Items 2, 7(b), and 12 with g Owners' Group within context of generic review (should be no problem with the SE for items 2 and 12, since licensees which referenced Owrs.rs' Group in Bulletin response committed to resolution of the issue between the staff and the Owners' Group).
4.
problems Licensees' responses were transmitted to Regional Offices late
.with respect to the specified deadline.
Inordinate time delay in getting responses from Regional Office to NRR via I&E HDQRTS (as much as 3-4 weeks,, in some cases).
C.
GENERIC REVIEW l.
Background
. Started in May Covers 25 operating reactors.
. Scope: Feedwater Transients, small break LOCA analysis, generic guidelines for operational procedures, and operator training.
. Initial information requests to g regarding small break LOCA analysis May 22, 1979.
Meeting with all licensees with g-designed operating plants - May 30, 1979 6
Owners': Group formed Scope: Analysis, Generic Guidelines for Operators e Subsequent information requests to Owners' Group Semiscale test predictions - early-July Small break LOCA analysis Small break LOCA analysis, Michelson's concerns, and operator guidelines - mid-July Michelson's concerns and analytical models - late-August
e Meetings with Owners Group Analysis - May 31, 1979 Guidelines for operators - July 18, 1979 Inadequate core cooling - August 30, 1979
, Owners' Group submitted report WCAP-9600 covering small break LOCA, Michelson's concerns, and generic guidelines for operators - June 29, 1979.
i Staff's generic report Meetings with all W licensees on AFW systems - mid-May First draft of ccmplete (except for analysis, and guidelines portion) report prepared by A. Thadani and distributed for comment - early-July Responsibility for report given to B&O T.tsk Force - early-July 2.
Current Status Compitte set of draft recommendations (except for analysis) in staff's generic report distributed to B&O management for concurrence.
~
Preparation of portions of generic report on analysis and operator e
guidelines underway (Analysis Branch reported on 9/10/79 that the draft would be ready 9/17/79).
e Letters transmitting requirements on AFW systess to licensees ready for signature.
Portion of generic report describing deterministic and reliability ass,essment of AFW systems under review by B&O management.
Owners' Group response to IEB 79-06C (WCAP-9584) received - late-August.
e
. Licensees referencing WCAP-9584 in IEB 79-06C responses.
3.
What's Coming Preparation of letters to licensees transmitting analysis requirement -
mid-September (contingent on completion of analysis review as scheduled for 9/17/79).
7 Completion of portions of generic report on analysis and operator guide-lines.
Complete and publish generic report - late-September (contingent on e
timely completion of portion on analysis and operator guidelines).'
Responses by Owners' Group to RAIs on small break LOCA analysis, e
.Michelson's concerns and operator guidelines - due 9/17/79, advance copy already under review.
Completion of review of WCAP-9584 - mid-October.
e Resolution of HPI termination criteria issue - mid-September.
i
~
4.
Problems
- Potential for slio in completion date of analysis and guidelines portion i
of' generic-report contingent on adequate responses to RAIs could cause delay of completion of generic report i~ Controversy over portion of generic report dealing with deterministic and reliability assessment of AFW systems.
- Size of generic report has discouraged a thorough peer review.
