The Part 21 report does not affect Diablo Canyon Units 1 and 2 since no Class 1 pipe clamps manufactured by NAVC0 were purchased or utilized at Diablo Canyon.

Kindly acknowledge receipt of this material on the enclosed copy of this letter and return it in the enclosed addressed envelope.

Sincerely, -
