DOCKETNO.40_-$33 BWR REFUELING BRIDGE The attached memorandum from Mr. Ilunter of this office identifics a potential for fuci damage by operator error in either the reactor cavity or fuel pool (.f CE BWRo. I_n the specific instance identified,-a new fuel assembly was damaged, therefore, there were no radiological consequences.

It is recognized that the consequences of fuct damage resulting from-excessive movement of the refueling bridge and/or trolley while withdrawing or inserting an irradiated fuel assembly are within the refueling accident-analys!s. Our concern is that the probability ot damage due to operator

~

error may be higher than we should accept. Refueling bridge end trolley drives in Westinghouse plants are interlocked to reduce the probability of fuel _ damage due .to operator error.

As discussed with you by telecon on April 7. 1976, we request a review of this matter cc appropriate. Mr. Hunter and others of this offico can be made available for detailed discussion of refueling practices, experiences and interlock functions.
