Not applicable to Waterford. South Texas had some thimble issues that may be applicable. BWRs have this problem, think in their box. I have some contacts if you need it.

'C' detector also became stuck while in Emergency in a couple of 'D' thimbles, as well as a couple of its own 10-Path thimbles. We have discovered a small amount of water near the drain hole of the 'D' 10-path box, but cannot determine which thimble it originated from based on visual inspection.

Morning Whiting, We only require FHS/SRO for "Refueling Operations" (e.g. fuel moves within the vessel, see our Tech Spec definition below) and for heavy loads (e.g. Head Removal) over the reactor vessel if it contains fuel. "Refueling Operation Any operation involving the shuffling, removal, or replacement of irradiated fuel outside of the reactor pressure vessel. The suspension of any REFUELING OPERATION shall not preclude completion of movement of a component to a safe, conservative position." We will be moving fuel out of the Spent Fuel Pool into Casks in a few weeks and I have the Shift Manager authorizing the activity and independently verifying some Tech Specs requirements but there is no requirement for a FHS/SRO.

Palisades does not require an SRO for fuel handling activities in the SFP, only the Reactor side. ________________________________ From: respvr-bounces(a)retaqs.com [mailto:respvr-bounces@retaqs.com] On Behalf Of Delk, Whiting S.
