SUBJECT:

BWROG MANAGEMENT MEETING REPORT

\\

The August 2, 1990, Management Meeting between tha BWR Owners' Group and NRR was held as scheduled. Due to the effectiveness of these meetings, their scheduling has been increased from two to three meetings per year.

et the request of BWROG. Enclosure 1 is the BWROG. handout provided at the meeting, which includes the meeting agenda as well as background i

information on selected agenda topics. is a listing of

[

meeting attendees.

These meetings are held to discuss the status of ongoing issues of l

interest to the Owners' Group and staff, as well as identification of new iscues which will be the subject of Owners' Group activities.

The Owners' Group expressed their satisfaction on the effectiveness of f

these meetings in monitoring progress on the programs Ond enhancing interactions with the staff, r

Some topic specific information of interest which was discussed at the meeting incleded:

I BWR Stability /ATWS BWROG is completing their assess-ment, focus will likely be pro-cedure based.

Expect draft report to staff by December, with final l

in January 1991.

MSIV Leakage Control System BWROG inqtiired on schedule, staff committed to provide.

Current in-formation is that staff hopes to-have SER completed by end of March i

1991.

However, a one to two nonth.

i delay is possible due to needed changes in OG radiological. assess-ment computer code.

William T. Russell Septenber 5,1990 HOV Testing The staff expressed the importance of this istJe, and noted t1at valve mispositioning was also still an issue along with closure capability against pressure differential.

Staff noted that inspections will be delayed to allow industry review of -

Supplement 1 to GL 89-10. Staff also committed to participate in a meeting in near future to discuss position on licensing basis and operating ex-perience on mispositioning. This meeting is scheduled for Sept. 7.

ATWS Diversity Owners' Group inquired on status of I

their. appeal. The staff expects it to be signed out by ED0 shortly.

RG 1.97 Neutron Monitoring The OG indicated that they will appeal staff's position requiring neutron flux monitoring. The appeal is now under staff review.

MSL Red Motiitor OG inquired on schedule.

Expected staff completion date is end of October.

Containrent Testing Staff will be responding shortly to OG coments directed to their ex-l pectation of proposed Appendix J leak testing rule change.

Rule and RG changes currently underway by

staff, i

i Channel Box Bow The staff expressed their concern regarding reuse of channel boxes, and noted that a formal position would be forthcoming shortly. Operational issues regarding the six plants cur-i rently reusing boxes.is also undar i

staff consideration and will be i

decided shortly.. - Staff-comented that at present no consistent method for determining CPR penalty was being utilized.

. William T. Russell Sept. amber 5,1990 EPGs Staff expressed concern over incon-sistencies between plant licensin basisandEPGs(NCADoneexample)g The staff will anticipate follow-up by OG to resolve these inconsistencies.

For more information on these topics, please contact the responsible Branch Chief or sqyself.

PERFORMED IN RESPONSE T0 AE00 STUDY

,l i

NEDC-31339 SUBMITTED TO NRC IN DECEMBER 1986 o

CONCLUSIONS OF BWROG STUDY:

i j

1) SAFETY MARGINS DURING OVERPRES$URIZATION GREATER THAN THOSE SPECIFIED IN ASME CODE 4

2) CONDITIONAL PROBABILITY FOR ECCS PRESSURE BOUNDARY RUPTURE IN THE EVENT OF OVERPRESSURIZATION IS 3.0E-5/ EVENT (2-3 ORDERS OF MAGNITUDE LESS THAN AEOD l

STUDY SHOWED) i

3) REALISTIC FREQUENCY OF ECCS INTERFACING LOCA CAUSED BY l

OVERPRESSURIZATION IS 3.0E-7 PER REACTOR YEAR (AEOD l

" JUDGED" 1.0E-4 TO 1.0E-5).

l

4) MOST PROBABLE RESULTS OF OVERPRESSURIZATION ARE MINIMAL, AND OVERPRESSURIZATION CONDITION WOULD BE TERMINATED 1

EARLY BY OPERATORS REACTING TO ALARMS 4

5) LOW DESIGN PRESSURE ECCS AND RCIC SYSTEM INTEGRITY SHOULD BE MAINTAINED SHOULD OVERPRESSURIZATION OCCOR o

BWROG HAS ALSO MADE RECOMMENDATIONS TO REDUCE OVER-PRESSURIZATION EVENT FREQUENCY b
