Dear Mr. Denton:

My letter of June 3, 1982 transmitted information in regards to containment boundary f racture toughness as requested by Elinor G. Adensam's letter of May 24, 1982.

The specification for the Lowest Service Metal Temperature of the containment plates should have been given as 10 F. A corrected copy of the containment fracture toughness data is attached.

Very truly yours, ?
