Re:

10CFR21 Report of Situation related to Washington Public Power Supply System Nuclear Project No. 1

~

J This report is submitted to provide details of a situation reported to you by Telex on May 9,1980.

The situation 'nvolves the use of an earlier revision of amplified j

response spectra in the design of two safety related tanks on the subject project.

Details as required by 10CFR21, paragraph 21.21 (b) (3) are contained in the attached report.

It can be noted in these details that the situation has been evaluated as not a defect as defined in paragraph 21.3 (d).

This situation was initially known to the NRC during an LCVIP I v ec-ion of our Philadelphia operation during May 25 to 29, 1979.

Details at (

point may be found in the NRC report of that inspection and our reply to j

the NRC dated July 12, 1979.

l If any additional information is desired, please contact me at any time.

Very truly yours, o

30 South 17th Street Fhiladelphia, PA 19101 IDENTIFICATION OF THE FACILITY, THE ACTIVITY, OR THE BASIC COMPONENT SUPPLIED FOR SUCH FACILITY OR SUCH ACTIVITY WITHIN THE UNITED STATES WHICH FAILS TO COMPLY OR CONTAINS A DEFECT.

Washington Public Power Supply System (WPPSS), Units WNP-1 & WNP-4; the design, fabrication, and erection of the Borated Water Storage (BWST) and the Demineralized Water Storage (DWST) Tanks.

IDENTIFICATION OF THE FIRM CONSTRUCTING THE FACILITY OR SUPPLYING THE BASIC COMPONENT WHICH FAILS TO COMPLY OR CONTAINS A DEFECT.

Welk Brothers' Metal Products, Inc., P. O. Box 19099, Spokane, WA 99219, is the firm supplying the tanks.

Design parameters, such as seismic response input, have been supplied by UE&C.

Based upon the design parameters, the vendor is responsible for design, fabrication, and erection of the tanks at the job sit'.

At the time of identification of the deviation, the tank shell plates had been shipped to the job site, but had not been ?rected.

l NATURE OF THE DEFECT OR FAILURE TO COMPLY AND THE SAFETY HAZARD WHlCH IS CREATED OR COULD BE CREATED BY SUCH DEFECT.0R FAILURE TO COMPLY.

Refer to USNRC, Region IV, letter dated June 14, 1979, Notice of Deviation and Section 11.8.3 for details of the potential defect.

This deviation could potentially have resulted in a loss of safety function of the subject tanks.

i Evaluation of this deviation revealed that a defect, as defined in 10CFR21, did not exist; hence a substantial safety hazard could not have been created.

THE DATE ON WHICH THE INFORMATION OF SUCH OEFECT OR FAILURE TO COMPLY WAS OBTAINED.

USNRC QA Program Inspection conducted during the time period May 21 - 25,1979.

IN THE CASE OF A BASIC COMPONENT WHICH CONTAINS A DEFECT OR FAILS TO COMPLY, 2

THE NUMBER AND LOCATION OF ALL SUCH COMPONENTS IN USE AT, SUPPLIED FOR, OR' BEING SUPPLIED FOR ONE OR MORE FACILITIES OR ACTIVITIES SUBJECT TO THE REGULATIONS IN THIS PART.

l Not applicable; the poteatial defect concerned the unique application of a seismic response spectra to a unique set 4

of components.

AND THE LENGTH 0F TIME HAS BEEN OR WILL BE TAKEN TO COMPLETE THE ACTION.

The corrective actions.aken are complete and did not result in i

i identification of any defect or substantial safety hazard in the design of the Borated Water Storage or Demineralized Water Storage Tanks..The proper seismic response spectras.for the BWST and DWST i

tanks were incorporated into Specification 243, the vendor has re-analyzed the tank seismic response, and UE&C has reviewed the analysis.

No changes were required to the tank design, fabrication or erection.

- The revised seismic response spectra was issued to the Contractor, by Change Order, on July 23, 1979.

The vendor submitted an addendum to existing stress reports for the BWST and DWST tanks on September 28,.

1979 confirming that the net seismic response of the tanks is slightly i

less than was originally calculated, and that no changes to the tanks I

were required.

ANY ADVICE RELATED TO THE DEFECT OR FAILURE TO COMPLY ABOUT THE FACILITY,
