Dear Mr. Reid:

8 Re: St. Lucie Unit 1 E..-

Docket No. 50-335 Fracture Toughness and -Potential For Lamellar Tearing of Steam Generator and Reactor Coolant Pump Support Materials On September,14, 1977, in a letter from Mr. Don K. Davis, the NRC requested that Florida Power.a'ight Company prove.'de information concerning fracture toughness and the potential for lamellar tear-ing in. the steam generator and reactor coolant pump support materials for St. Lucie Unit l.

Please be advised that this information was turned over to NRC staff reviewers during a meeting in your offices on May ll, 1978.

Very truly yours, Robert E. Uhrig Vice President REU/MAS/mb cc: Mr. James P. O'Reilly, Region II Harold F. Reis, Esquire 781640026 Iws/~
