Here's what we have from Oconee. We have used PackBots and Spot in the basement and upper floors at 100%, but we have nothing currently that would get us to the RCP seal areas inside the D-Rings. We power down to around 25% for personnel entries to those areas. From our history the dose reduction is pretty much linear.

Rates from N-16 around the Hot Legs and Cold Legs is around 10 REM/hr at 100%.

Good luck.

Davis Besse is requesting for any available radiological data / plans / technology utilized for a containment entry at 100% power within the Bio-shield walls to include traversing onto the RCP seal platform to investigate RCP performance.
