U. S. Nuclear Regulatory Comission, Region V Office of Inspection and Enforcement 1450 Maria Lane, Suite 260 Walnut Creek, California 94596-5368 Attention: Mr. B. H. Faulkenberry Chief, Reactor Construction Projects Branch

Subject:

WASHINGTON NUCLEAR PROJECTS NOS. 3 AND 5 NRC INSPECTION REPORT NO. 50-508/81-08 and 50-509/81-08 ITEM 0F NONCOMPLIANCE A (81-10/01)

Reference:

NRC, Region V Letter, dated November 9,1981, B. H.

Faulkenberry to R. S. Leddick, same subject.

The referenced letter requested the Supply System ascertain whether the " worst case" heat input was used for the weld proced'ure qualifi-cation testing perfonned in conjunction with the corrective action for item of noncompliance A (81-10/01).

The weld procedure, PXS-WPS-8A, Rev. 5, was qualified to the " worst case" heat input permitted by the WPS.

It should be noted that the definition of"" worst case" includes the Sumer 1980 addendum change to ASME Code Section IX. This allows the specified interpass tem-perature to be 100 F higher than experienced during the procedure qualification tests.

It is our belief that this definition of " worst

~

case" meets the intent of your previously stated position on this subject.

Should you have any questions or desire further information, please contact me directly.
