  • Activity as of July 8, 1985 No Co-58 activity was measured in the nickel wires due to the long decay time following removal of the capsule from the reactor and the rela-tively short half life of the isotope (70.8 days).

30 stout capsule was in the reactor for 2975 equivalent full power days or l

8.15 effective full power years (EFPY).

The power history calculation was based on the assumotion of a 1930 MWt nominal full power output over the entire operating period.

An EFPY value of 3.38 was reported from rea: tor baseline dat1*; the difference between these EFPY values is due to the assump-tion of a constant nominal fJll-oower thermal output over the entire coerating period for the smaller value.

The E > 0.1 MeV and E > 1.0 MeV full power flux and fluence calcu-lated from initial startup to Februarv 1983, are given in Tables 5 and 7, respectively, for each of the dosimetu wires along with the werage of the flux and fluence derived from each wire.

Also, the ave' age values for the iron and the copper wires are included.

The nickel monitor could not be used since the initial Co-60 content is not known.

The average values of the I,,

results for all dosimeters also are given in the tables.

vessel inner wall, at 1/4 T and 3/4 T directly behind the capsule (210-degree orientation), and at the maximum position (223.49-degree orientation) were calculated.

The flux results are tabulated in Table 8.

The end of life (EOL) fluences were also calculated and gia n in this table.

These values were cal-culated assuming a pressure vessel lifetime of 40 years and a reactor oper-ating power level of 80 percent.

The fine mesh and time-integrated relative power values shown in Figure 4 for each fuel assembly were used in the 00T 4.3 code to generate the values in Table 8.

A plot of neutron flux (E > 1.0 MeV) as a function of azimuthal angle (in degrees) is shown in Figure 6.

The fluence values at the maximum position for the inner vessel wall surface, 1/4 T, and 3/4 T positions are plotted as a function of time in terms of EFPY for the Oyster Creek pressure vessel in Figure 7.

To account for the axial fluy profile, a representative source distribution was used to estimate the axial peaking f actor at the waii.

The flux distribution near the core midplane is fairly flat and the axial factor used is 1.017.
