W. D. Kelley, Reactor Inspector Date Inspector's Evaluation (continue on attached sheet, if necessary)

No items of direct safety concern were identified.

No item other than the new unresolved item in the sumnary is to be includah' in the letter to the licensee.

TVA-DEC has measured the wall thicknesses of all valves in Class I safety system 11/2 inch nominal pipe size over as required by RO:II's letter of June 30, 1972. The procedure, instrument and calibration blocks were reviewed with the technicians who performed the measurements and in the opinion of the i

inspector the measurements were made within the accuracy required in RO:II's I

letter of February 15, 1973, enclosure item 2.

.o TVA has stated that all of the valves meet the minimum wall requirements; however, the inspector questions their blind acceptance of wall thickness requirements given them by GE on their supplied valves.

TVA has measured the wall thiakness of all valves in Class I safety systsas 1 1/2 inch nominal pipe size average in accordanes with their preesse specifications 5.M.1.1(a) "Spesifiaation for Think====

Measurements" dated September 6,1972 with the exception of the I

valves manufactured by Dooling Yalve Manufacturing Company. These i

j valve all thicknesses had been previoesly suasured by the weder sad e

these with wall thich=assee less them specified on the design drawing i

were repaired. This meets the requiressat of W II's of l

Q.

June 30,1972 that required demonstrations that the valve wall

-f 7-thicknesses were acceptable for valves over 11/4 inch moniaal ytys., i 3 size in water lines and 2 1/2 inch nominal pipe size in steam 11 ass for boiling water reactors.

i TVA did not invoke their stated exception in their letters of 1521 l,

September 29, 1972 and December,1, 1972 to measure the wail thiek-1 ness of east steel valves larger than 2 inch nominal pipe sine in water lines and 4 inch nominal pipe size in steam 11 ass. The valves i

times. ped to the letter of september 29, 1972 extended to meet 30 of Joe 30,1972 and inaluded forged steel valves.

Instead of invoking their statessut in their letter of December 1,1972 that measurements of all Class I safety system valves in Units 2 sad 3 would provide the level of confidenne required to gearsates that all Unit i valves met the standards and specifications oder whiah they I

i were purebased, all valves in Unit 1 were anamured in aseendense with l

thickness measurements have been made of Class I safety system valves as required by 30 II's letter of February 15, 1973, emalesure, item 1, " Valve Sise".

b'l R e requirement of the enclosure item 2, " Acceptable Measuremmat l

l Teehaiques and Accurney" to attempt to unet a 21===4-error in I

repeatability and accuracy has been met. This has been demonstrated by eenparing physical measurements with ultrasosic measurements of i

l calibration test blocks and comparing these valves against phq' 7 j

and ultrasonic usamureaants of uninstalled valves.

y TVA did not invoks the enclosure item 3 " Conditional Acceptance" l

or item 4 " Valve Verification Alternatives".

All valve wall thickness asasurement data sheets were tramanitted to 00 t-i DED-Knoxville for evaluation. It was not known by the site constreetion foress if any valve would require the condition imposed by emelosure item 5 " Valve Acceptance Brough Evaluation or Special Testing".

l Me iss11 skiskness measurement data sheets were audited by l

the inspector in TVA-DED Knoxville office on May 29, 1973. Me i

j inspector was informed that only one valve OdrL-2-71) out of eleves l

identified safety valves supplied by GE had an area that was questimmed.
