Dear Mr. Stolz:

The information requested in your letter dated September 8, 1977 concern-ing the fracture toughness and potential for lamellar tearing of steam generator and reactor coolant pump support material, is being prepared and is scheduled for submittal to the NRC by November 11, 1977. We anticipate that our own evaluation of the fracture toughness of the steam generator and reactor ecolant support materials for Davis-Besse Nuclear Power Station Unit No. I will also be available for submittal by November 11, 1977.

Yours very truly, o

tyy, s bj e/1 i
