ForUnit5, Cycle 3 operation,thecurveillancecepuleswill 4.2410 be removed from the reactor vessel and the provisions of Specification 4.2.9 will be revised prior to Cycle 4 operation.

For Unit 2, Cycle 2 operation, the surveillance capsules will be removed from the reactor vessel and the provisions of Specifica-tion 4.2.9 will be revised prior to Cycle 3 operation. For Unit 3, Cycle 1 operation, the surveillance capsules will be removed from the reactor vessel for a portion of the cycle and the pro-visions of Specification 4.2.9 will be revised prior to Cycle 2 operation.

4.2.11 During the first two refueling periods, two reactor coolant system piping cibows shall be ultrasonically inspected along their longitudinal wc]ds (4 inches beyond each side) for clad bonding and for cracks in both the clad and base metal. The elbows to be inspected are identified in B&W Report 1364 dated December 1970.

Bases The surveillance program has been developed to comply with Section XI of the ASME Boiler and Pressure Vessel Code. Inservice Inapection of Nuclear Reactor w.

The program places emjor emphasis on the area of highest stress concentrations and on areas where fast neutron irradi_ tion might be sufficient properties.

to change material The reactor vessel specimen surveillance program for Unic 1 and Unit 2 is based on equivalent exposure times of 1.8, 19.8, 30.6 and 39.6 years.

The contents of the dif ferenc type of capsules are defined below.

A Type B Type Weld haterial HAZ Material HAZ Material Baseline Material Baseline Material l

For Unit 3, the Reactor Vessel Surveillance Program is based on equivalent 1

cxposure times of 1.8, 13.3, 26.7, and 30.0 years.

The specimens have been celected and fabricated as specified in ASTM-E-185-72.

Early inspection of Reactor coolant System piping elbows is considered desirable in order to reconfirm the integrity of the carbon steel base metal when explosively clad with sensitized stainless steel.

If no de, gradation is cbserved during the two annual inspections, surveillance requirements will revert to Section XI of the ASME Boiler and Pressure Vessel Code.
