ECAR 4951 BSU-8242 3 DPA As-Run Physics Analysis

Abstract

BSU-8242 3 DPA As-Run Physics Analysis 11. Conclusions/Recommendations: An MCNP full core physics model was used to calculate the as-run heat rates, flux values, fluences, and DPA for each test specimen within the BSU-8242 experiment. The heating rates ranged from 6.67 to 17.37 in position A-6 (300C 3 DPA Capsule), depending on the material and axial location; the heating rates ranged from 5.14 to 16.38 in the A-7 position (400C 3 DPA (Y)), and the heating rates in the A-8 position (400C 3 DPA (X)) ranged from 5.25 to 9.81 . The average neutron flux experienced by the BSU-8242 specimens in position A-6 was ~9.08× 10 14 2 • , while the average fluence was ~1.47 × 10 22 2 ; The average neutron flux in position A-7 was ~8.31× 10 14 2 •

“…Details of these calculations are provided in refs. (Brookman, 2018;Hale, 2018). and summarized in ref.…”

“…Fluxes ranged 8.08-9.61 × 10 14 neutrons/cm 2 •s, with fast (>1 MeV) flux components ranging 1.60-1.96 × 10 14 neutrons/cm 2 •s. As-run fluences (Brookman, 2020) and temperatures (Davis and Hone, 2020;Hale, 2021) are tabulated for each specimen in ref. (Guillen et al, 2023).…”

“…The dose rate in Table 1 was deduced from as-run neutron fluence divided by irradiation time. The irradiation conditions, e.g., temperature and dose, will be compared with the analytical reports of the University of Wisconsin Pilot Project [11,12,13].…”
