SUMMARY
OF BRIEFING ON LMR RESPONSE TO A STATION BLACK 0UT EVENT On August 8, 1985 DOE and EPRI personnel provided us with a briefing on how LMRs intend to accommodate a station blackout. The requirements and design criteria to be applied to address the station blackout issue were presented as well as plant response to a station blackout event using the large Scale Prototype Breeder (LSPB) design as an example. The agenda and list of attendees are enclosed. Copies of the handouts from the briefing are available in my office.
Significant points from the meeting were:
1)
The criteria to be applied to the LMR designs are consistent with the requirements that have been developed under USI-A-44 " Station Blackout" for LWRs.
2)
The plant response to a station blackout event is intended to maintain coolable core geometry. However, loss of plant lifetime is permitted by the. designers in the event of a station blackout event.
3)
LMRs, due to their enhanced natural convection and leak tight, low pressure system properties have a high potential of being able to withstand a station blackout of long duration.
.If and when we commit to further ir.teractions in the LMR area it is DOE's intent to formally submit a generic report on LMR station blackout for our review.
If you would like to see the handouts from the meeting or discuss any of the above further please let me know.
