Subject:
Auxiliary Building Crane Modification R.
E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Zwolinski:
In a letter dated January 18, 1984< Rochester Gas and Electric requested a change in the Technical Specifications to allow handling of a spent fuel shipping cask at Ginna.
This request was based upon a proposed modification of the 40T Auxiliary Building Crane to satisfy the requirements of NUREG-0554.
In Section 8 of NUREG-0554I the requirements for load testing state that "The tests should include all positions generating maximum strain in the bridge and trolley structures...."
In response to NRC Staff questionsE we are taking exception to this requirement to the extent that the 50% and 125% test loads will be lifted only inches off the bed of the transporting truck and will not be moved to other positions in the auxiliary building".
This is necessary because of the potential consequences of the load drop from greater heights in an operating plant.
A brief outline of the proposed testing program is attached.
Note that the program will be in accordance with ANSI B30.2.0.
er truly yoursi e./
