f l I g D. C. COOK UNIT NO. 1 REACTOR VESSEL MATERIAL SURVEILLANCE PROGRAM 1.) The estimated maximum fluence (E > 1 Mev) at the inner surface of the reactor vessel as of March 31, 1977 is 8.38 x 10 n/cm~.

2.) The effective full power years (EFPY) of operation accumulated as of March 31, 1977 is 1.34 EFPY.

3.) Fabrication of the reactor vessel was performed by Combustion Engineering, Inc.

4.) a.) Sketch of the reactor vessel showing materials in the beltline region

=-is shown in Figure l. I b.) Information on each of the welds in the beltline region is shown in Tables 1 through 4.

c.) Information on each of the plates in the beltline region is shown in Tables 4 through 8.

5.) Information relative to the weld and plate material in the material surveillance program is shown in Tables 1 through 3 and 5 through 8.
