DRESSER-SUPPLIED PRESSURE GAGES '( /

Dear Mr. O'Reilly:

Attached is a second interim report on the subject item of which you were notified as potentially reportable per the provisions of 10CFR50.55(e) and 10CFR21 on September 23, 1981. Dresser Industries, Ebasco, and CP&L are continuing to evaluate this matter. As Atated in the second interim report, the evaluation for reportability will not be complete until the culmination of seismic testing currently projected to begin in April,1982. A final report will be issued by December 9, 1982.

Thank you for your consideration in this matter.

Yours very truly, I

1 SHEARON HARRIS NUCLEAR POWER PLANT UNIT NO. 1 Second Interim Report March 30, 1982

(..-.. .....

Potentially Reportable Under 10CFR50.55(e)_ and 10CFR21

I .

Pqs 1 of 3

SUBJECT:

10CFR50.55(e) Potentially Reportable Deficiency Shearon Harris Nuclear Power Plant - Unit No.1 Seis=ic Testing of Pressure Gages Ebasco Purchase Order NY435104 .

ITEM: Bourdon - Type Pressure Gages SUPPLIED BY: Dresser Industries Industrial Valve and Instrument Division Stratford, Connecticut 06497 NATURE OF DEFICIENCY : The deficiency involves Seismic Category I Pressure gages. The sages were delivered to the Shearon Harris Site prior to completion and documentation of seismi.c testing.

DATE PROBLEM WAS CONFIRMED TO EXIST: Sep tember 23, 1981 - Shearon Harris Site personnel ,

discovered that documentation was not available for Seismic I pressure gages.

PROBLEM REPORTED: Seo tember 23, 1981 - L. E. Jones (CP&L) reported the item-

,. as potentially reportable to Mr. R. Butcher, Region II, 4: ' Nuclear Regulatory Commission.

October 7,1981 - CP&L personnel (E. Evans) requested

. Ebasco (X. Pique) to conduct an evaluation.

SCOPE OF

. PROBLEM: The problem is confined to seismic pressure gages having either steel or bronze Bourdon tube mechanisms. Thirty-eight purchase order items, consisting of a total of 38

. pressure gages are involved.

SAFETY IMPLICATIONS: The pressure gages are classified as Seismic Category I, and installed in safety-related piping systems. The gages are installed directly on pipes or on instrument panels.

In the latter case, small diameter piping or tubing connects the gage to the pressure boundary.

Failure of the pressure gages to retain pressure boundary integrity during or after an earthquake could adversely affect the safe operation of the plant.

! REASONS PROBLEM IS POTENTIALLY RE?ORTABLE: Duri'ng a routine inspection by Ebasco at Dresser's plant on October 1 and 2,1979, the Ebasco inspector rejected a shipment of pressure sages because documentation was not complete. Some time thereafter, Dresser Industries inadvertently shipped so=e of the Seismic I pressure gages that were previously rejected, without obtaining the proper Ebasco release and before ce=pletion of Seismic testing.

The Seismic 1 pressure gages apparently were delivered to the Shearon Harris Site as part of a shipment consisting primarily of Non Nuclear Safety pressure gages.

A seismic test procedure for pressure gages (Dresser Report

• # ASH-131EI dated 2/20/75) has been submitted to Ebasco for review. Ebasco made comments on this report (Ebasco letter to Dresser SH-251-385 dated 1/14/81). To ' date , no seismic tests have been conducted on these gages.

The question of reportability is addressed in this report as a potential breakdown of Dresser's Quality Assurance

, Program, which permitted Safety-related ite=s to be shipped without the required Ebasco inspection, and prior to the ce=pletion of seis=ic testing.

j

-([g~_____. . _____

To determine whether this deviatio'n, if left uncorrected, could create a substantial safety hazard, seismic tests will have to be conducted.

• Seismic test results for both steel-type and bronze-type pressure sages are not yet available. Evaluations by Ebasco cannot be completed at this time. Therefore, a final determination of reportability cannot be made until tests are cc=pleted and evalu'ated.

The seismic testing and required review of the seismic report are scheduled for co:pletion by December 9,1982 at which time evaluations will be completed. A final report will then be prepared and issued.

• I CORRECTIVE ACTION: 1) Seismic I Pressure gages from Dresser delivered to the Shearon Harris site have been placed on "QA Hold" as of 9/23/81.

2) Dresser Industries has been made aware of this report I

and will be requested to provide co=ments, prior to preparation of the final report.

Page 3 of 3 3)- Seismic testing will be concu'eted by Dresser / Dayton T.

Brown Co. The results will be reviewed by Ebasco. A total of four tests will be conducted; two tests on panel-mounted instruments and two tests on pipe-mounted -

instruments: one test each for bronze Bourdon tubes, and steel Bourdon tubes. Results will be presented in the final report which is scheduled for completion by.

December.9,'1982.
