SUMMARY

i The fast neutron flux density and fluence (integrated neutron flux) at a

! capsule near the reactor vessel wall of the Clinton Station of the Illinois Power Company have been determined to be:

4.6x10e n.ca 8.s 1 >l MeV full-power flux density 7.4x10' n.cm 8.s 1 >0.1 MeV full-power flux density

1. 1.4x1017 n.ca 8 >l MeV fluence

! 2.3x1017 n.ca 2 >0.1 MeV fluence .

.a i following the analysis of irradiated iron flux dosimeters, in accordance with

! the GE CM&S Method No. 10.1.6.0 R3.

f EXPERIMENTAL 1

l Three iron wires were irradiated in a GE pressure vessel capsule holder at

Clinton Station from March 31,1987 (startup) to January 2,1989 (and of cycle 1). Each wf.re was removed from the capsule, cleaned with 4N HNO3 , weighed, a mounted on a counting card, and analyzed for Mn-54 content by gamma spectro-

! metry at a calibrated 4 cm source-to-detector distance with 100-ce and 80-ce Ge(Li) detector systems.

From daily thermal power generation summary tables, four irradiation time periods for Cycle 1 were calculated. Operating days for each period and the reactor average power fraction are shown in Table 1. Zero power days between periods are also listed.

NO. 89-212-0039 DRF A00 02764 i DISCUSSION OF RESULTS 1 From the activity measurements and power history, a reaction rate for s4Fe(n,p)5*Mn was calculated. These data appear in Table 2. The Clinton 4

Station >l w a v flux density reaction cross section for iron was calculated to be 0.142 vart . This value was obtained from measured cross section data functions #r a more than 65 spectral determinations for BWRs and for the GE

Test reactor using activation monitors and spectral unfolding techniques.

i These data functions were applied to BWR pressure vessel locations based on water gap (fuel to pressure vessel) distances. The >l MeV/ >0.1 MeV cross section ratio at BWR pressure vessel locations is approximately 1.6.

The determined full-power flux density and actual fluence reruits at the reactor vessel wall capsule holder location are given in Table 2. The >l MeV and >0.1 MeV values of 4.6x108 and 7.4x10' n cm 2.s 1 were calculated by 4

dividing the reaction rate measurement data by 0.142 barns and 0.0888 barns,

respectively. The corresponding fluence results,.1.4x1017 and 2.3x1017 nicm 2
were obtained by multiplying the full-power flux density by the product of the i total seconds irradiated (4.709x107s) and the full-power fraction (0.665).

The 2a errors of the values in Table 2 are estimated to be:

i 54 for dps/g i

j t 104 for dps/ nucleus (sat'd)

{ i 256 for p and pt >l MeV 354 for p and pt >0.1 MeV 5
