'e m2ei A82-494B June 28, 1982 Director of Nuclear Reactor Regulation Attention:
Mr. John F. Stolz Operating Reactors Branch No. 4 Division of Operating Reactors United States Nuclear Regulatory Commission Washington, D.C.

Dear Mr. Stolz:
A commitment was made in a Toledo Edison letter dated July 10, 1980, (Serial No. 627) to inspect all Cycle 2 Fuel Assembly Holddown Springs at the Davis-Besse Nuclear Power Station Unit No. I during the second refueling outage. That inspection has been completed during the current refueling with one spring reported broken.
The broken spring at Davis-Besse has be en replaced and was from heat treatment number HT2405X which is used t.n all B&W operating reactors.
Out of the 177 fuel assemblies examined at Davis-Besse, only the single spring has been identified as broken and is currently under evaluation by B&W.
This failure is considered an isolated instance within the realm of statistically expected occurrences.
Very truly yours,
