Fuel plus hoist underload setpoint provides protection to prevent fuel assembly movement out of the hoist.

This condition may occur if the hoist box becomes jammed during lowering of the hoist with the fuel assembly inside.

The overload setpoint provides protection for the machine against damage by lifting weights above certain limits.

The formulae provided below are obtained from Reference 4.

The setpoints are calculated conservatively without accounting for the VFRA weight.

ACTIONS REDDIRED

)

It is recommended that fuel assembly and hoist box weights be i

measured during the outage to confirm the range of values used in l

4 this evaluation.

Fuel assemblies other than VFRA 1105 to 1155 pounds i

1305 pounds maximum i

VFRA 1130 to 1220 pounds Hoist Box If the measured weights differ from the above used weights in the non-conservative direction, the setpoints should be re-evaluated.

VERIFICATION.SmORARY:

4 This engineering evaluation, prepared per ENG QI 2.0, has been logically developed and used the necessary design and reference materials to support the conclusions derived.

The underload and overload settings evaluated here do not affect the safety of the i

These settings,

however, are used on the refueling p.' ant.

i equipmenn as trip setpoints to maintain loads on the assemblies j

witbin the desired values for safe fuel handling operations.

Therefore, this engineering evaluation has been classified 'as Quali's:y Related.

,/ 'j W Attached is an engineering evaluation performed by Nuclear Fuel to determine the refueling equipment load cell setpoints.

These setpoints are based on the available equipment and fuel assembly' weight information.

Revision 1 to this evaluation deleted the requirement that the actual weights of equipment be checked during the upcoming 1996 outage.
