Dear Mr. Schwencer:
Re:
Turkey Point Units 3 and 4
Docket Nos.
50-250 5 50-251 Reactor Vessel Nozzles While reviewing the guidelines for evaluating the issue of asymmetric LOCA loads, Florida Power
& Light Company (FPL) has identified the reactor vessel nozzle shielding plugs (sand plugs) as items needing further consideration.
The sand plugs ar e designed to be removed from the space above each reactor vessel nozzle weld area to allow access for the purpose of inservice inspection.
We have decided that it would be appropriate to include an analysis of the loading on the sand plugs as part of our analysis of the effects of asymmetric LOCA loads on other NSSS components.
In conformance with this conclusion, FPL intends to consider sand plug behavior as part of the overall asymIetric LOCA loads issue.
