Reference:

PPaL letter PLA-443 dated January 22, 1980

Dear Mr. Grier:

The referenced letter describes a condition which was submitted as being potentially reportable'nder the provisions of 10CFR50.55(e).

A field inspection program was conducted ising both visual and non<estructive examination methods. After completion of the field inspections, a finite element analysis was performed for the coped beams which had radii less than the specified L2 inch minimum. Fracture mechanics analysis was performed to evaluate .the significance of the kerfs and other cope related discontinuities.

Based on the results of the evaluation program we have concluded that the conditions noted are nonconforming conditions which are technically acceptable and will have no adverse effect on the safe operation of the plant and, therefore, have been determined to be not, reportable. All nonconformance have been identified and are- being controlled in accordance with Bechtel Quality Control procedux'es and will be dispositioned accordingly.

However, to preclude recurrence of similar nonconformance's, the pertinent Bechtel Quality Surveillance Plan procedures have been revised to zepxire Bechtel inspection personnel to examine structural members to assure that impx'opex'ly coped beams are not permitted to be shipped.

Very truly yours, rrT. Curtis Vice Pzesident-Engineering I
