Thomas A. Ippolito, Chief, Operating Reactors Branch #3, Division of Operating Reactors FROM:
John N. Hannon, Project Manager, Operating Reactors Branch #3, D0R
SUBJECT:
MEETING
SUMMARY
1 A meeting was held with representatives from Iowa Electric, CP&L, Commonwealth Edison, Philadelphia Electric Company, TVA,' GE, BNL, and Battelle-Columbus on October.6,1978.
The purpose of the meeting was (1) to have a presentation from GE to the NRC staff and Pipe Crack Study Group-describing the various recirculation pump riser nozzle safe-end designs currently in use on operating BWRs and (2) to have discussions with BWR licensees using the type 3 safe-end design to investigate any-possible relationship with the type. I safe-end design. A list of meeting attendees is attached as enclosure 1.
A GE handout used during their presentation is attached as enclosure 2.
The NRC Pipe Crack Study Group (PCSG) requested a table for each type-of design configuration listing normal and upset stresses and usage factors.
GE agreed to provide this information based on existing stress reports.
GE stated that if actual stress determinations are requested for each nozzle configuration, this would require extensive re-analysis and would have to be requested by the licensee for a specific plant.
This is berause the existing stress tabulations are based on emergency 3
1 conditions.
The PCSG requested design details for nozzle configurations in plants in the construction / pre-OL p' nase.
GE did not have thi information but stated that the new designs were different from any of the current operating BWR designs.
GE was not. recommending any. action at this time and none of the licensees represented indicated they were taking an action in excess of. code required ISI.
