SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION REGARDING MOVING A SPENT FUEL ASSEMBLY AND ITS ASSOCIATED LIFTING AND HANDLING COMP 0NENTS

Dear Mr. Kenyon:

Based on NRC staff review of the Millstone Units 1, 2, and 3, Haddam Neck, and i

Seabrook Unit No.1 Technical Specifications (TS) and Final Safety Analysis Reports (FSAR), there appears to be inconsistencies between the TS and the FSAR for (1) Millstone Unit 3 and Seabrook regarding the weight of a spent fuel assembly and its associated handling and lifting components and, (2) the impact load for the design of the spent fuel pool storage racks at Seabrook.

Section 3.9.7 of the Millstone Unit 3 and Seabrook TS states that loads in excess of 2200 pounds for Millstone Unit 3 and 2100 pounds for Seabrook shall be prohibited from travel over fuel assemblies in the storage pool. The Bases 2

for TS 3.9.7 for both plants states that the restriction on movement of loads in excess of the nominal weight of a fuel assembly and associated handling tool over the fuel assemblies in the storage pool ensures that in the event this load is dropped: (1) the activity release will be limited to that contained in a single fuel assembly, and (2) any possible distortion of fuel

}

in the storage racks will not result in a critical array.

1 i

Section 9.1.4.3 of both plants' FSARs state that the spent fuel handling tool l

weighs approximately 400 pounds and the weight of one fuel assembly is 1600 pounds.

Section 9.1.2.1 of the Seabrook updated FSAR states that the impact load for the design of the racks is based on a 17x17 fuel assembly, 8.426 inches square, 167 inches long, weighing 1616 pounds, and falling a distance of 18 inches to the racks at the worst possible orientation.

The TS seems to imply that the weight of one fuel assembly and its associated handling tool is 2200 pounds for Millstone Unit 3 and 2100 pounds for Seabrook. However, both the Millstone Unit 3 and Seabrook FSARs seem to indicate that the weight of one fuel assembly and its associated handling tool for both plants is approximately 2000 pounds.

Further, if the spent fuel storage rack design impact load for Seabrook is 1616 pounds as given in I

Section 9.1.2.1. of the Seabrook updated FSAR, this is significantly less than the previously mentioned TS limits.
