\.m./ April 20, 1999 MEMORANDUM TO: Cynthia A. Carpenter, Chief Generic Issues, Environmental, Financial ;
and Rulemaking Branch Division of Regulatory Improvement Programs Office of Nuclear Reactor Regulation FROM: Stewart L. Magruder, Project Manager .1%J % . d Generic Issues, Environmental, Financial and Rulemaking Branch Division of Regulatory improvement Programs 4 Office of Nuclear Reactor Regulation
SUBJECT:
SUMMARY
OF SEPTEMBER 2,1998, MEETING WITH THE COMBUSTION ENGINEERING OWNERS GROUP (CEOG)
On September 2,1998, a public meeting was held at the U.S. Nuclear Regulatory Commission (NRC) offices in Rockville, Maryland, between representatives of the NRC and the CEOG.
Attachment 1 provides a list of attendees.
The purpose of the meeting was to discuss a CEOG outage initiative related to alternative decay heat removal in Mode 6/ refueling. The CEOG representatives stated that unless the staff raised issues during the meeting that appeared to be unresolvable, they intend to submit a l generic topical report on this issue. The CEOG presentation material from the meeting is included as Attachment 2. !
1 The CEOG representatives stated that the proposal to allow increased options for decay heat removal in Mode 6 has several benefits. Among the benefits are improved plant safety resulting from less fuel movement and more time for the fuel inside containment. It would also -
allow for decreased outage time due to the ability to remove the shutdown cooling system frcm i service for maintenance. The CEOG representatives noted that changes to plant Technical-Specifications would be required to implement this proposal and the bracketed numbers in the k
FI i presentation are typical values.
Following the CEOG presentation, the staff raised several questions for the CEOG to consider:
- 1. Whit .vould be the safety classification of the alternate shutdown cooling system?
- 2. Does this proposal depend on containment cooling?
- 3. Does this proposal increase the importance of maintaining the cavity seal and nozzle dams?
- 4. Would the spent fuel pool purification system be secured?

The staff stated that, although they would review the topical carefully if submitted, they did not i see anything in the presentation that would cause them to reject the report.
