Carl,
Here is the standard we use for moving fuel. There are no standards for FOSAR or inspection related activities, unless we are moving fuel.
"Water clarity is sufficient, under lighted conditions, to observe the top of a fuel assembly for possible obstructions or debris, in the following locations:
* Spent Fuel Pool * Transfer Canal * Reactor Cavity"

Does your station have water clarity or lighting standards for core inspections? (FOSARs, alignment checks, ID verifications, etc.) At Oconee Nuclear Station we only have qualitative standards (procedure and PJB directs the inspector to ensure there is adequate clarity and lighting).
Thanks,
Carl

It is a subjective call by the operators performing fuel moves. For inservice inspections the inspectors have a sample that they put into the core and are required to be able to read it with their cameras.

Carl,
Refueling SRO and RE ultimately determine if clarity is acceptable, which is obviously a little bit subjective. Our procedure states for offload, we need to see the top nozzles and for reload we need to see the alignement pins on the lower core plate. We have no stated clarity requirements for FOSAR or fuel inspections.
