. TASK ORDER NO. 6

1. SCOPE OF WORK Provide pipe weld testing and evaluation services for Regicn V, USf4RC.

Two welds are to be examined in situ at the Washington fluclear Project flo. 2 (WNP-2) site, in Benton County, Washington. "

2. OBJECTIVE OF TASK Determine whether the two welds in question have been subjected to radically excessive and non-uniform postweld heat treatment temperatures.
3. STATEf1ENT OF WORK Perform hardness tests and metallographic examinations on two welds at WNP-2. The two welds are located in two reactor feedwater lines inside the containment vessel. The welds are identified as: (1) weld no. 7 on WBG Isometric Drawing No. RFW-418-4 (entitled " Reactor Feedwater from Flowmeter to Reactor Vessel (Line A)"); and (2) weld no. 7 on WBG Isometric Drawing No. RFW-419-4 (entitled " Reactor Feedwater from Flowmeter to Reactor Vessel (Line B)"). In both cases the welds connect a 24" check valve to a pipe spool. Two types of tests are to be performed on each weld as described below:

Hardness Tests: -

Reference hardness tests and grain size determinations. .

Perform hardness tests in accordance with ASTM E-110-61, at six locations around the circumference of the weldment. At each location, test undisturbed base metal, base metal which has been exposed to heat treatment, the weld heat affected zone and the weld metal.

Metallographic Estimation of Average Grain Size:

Perform in situ metallographic estimation of average grain size at two locations around the circumference of the weldment. At each location, perform grain size estimation of the surface of undisturbed base metal, base metal within the zone of heat treatment, and the weld heat affected zone.

Estimation shall be accomplished in accordance with specification ASTM E112-74.

Photomicrographs shall be taken.

Evaluation:

The results of the above testing and estimation shall be evaluated to determine if the welds have been subjected to radically non-uniform and excessive postweld heat treatment temperatures.

y , a ..

gir0RTING REQUI'REMENTS Testing.and evaluation shall be reported in a final report, as follows:

Hardness Tests Describe the technique and equipment used, list equipment serial "

numbers and calibration dates, dates of tests, identify equipment operators, provide sketch and table to describe locations and actual va{ues of hardness readings.

Metdllographic Examination Describe the technique and equipment used, identify equipment operators, provide sketches to depict actual locations of examination, grain size estimation techique, ASTM E-112 worksheets, and photomicrographs.

Evaluation Describe the evaluation method, assumptions, basis for conclusions, and conclusions. Identify the names and qualifications of evaluators.

Any unusual observationsshall be verbally communicate to Region V, USNRC within two working days (George Spencer (415) 932-8300), and included in the final report.

5. DESIRED COMPLETION DATE Testing, evaluation, and report should be completed within one month of the date of issuance of this Task Order.
6. PLACE OF PERFORMANCE WNP-2 site, Benton County, Washington. Actual dates of testing to be --

coordinated with the Contractor and Washington Public Power Supply System by the NRC Region V.
