THERMAL NEUTRON FLUX AT THE HRE-2 CORE WALL, DETERMINED FROM ZIRCALOY-2 INDUCED-ACTIVITY MEASUREMENTS DURING RUNS 13, 14, 16, 17, 18, 19, 20 AND 21

Technical Report ·
OSTI ID:4120463
The thermal-neutron flux prevailing near the upper hole in the HRE-2 core wall was determined from measurements of the induced activity in a specimen cut from the edge of the hole. The specimen was removed following run 21 and was thus exposed to reactor neutrons during runs 13, 14, 16, 17, 18, 19, 20, and 21. The neutron flux, calculated for an average core power level of 2 Mw, was 2.8 x 10/sup 13/ neutrons/cm/sup 2//sec. The core wall area from which the specimen was removed was located approximately 16 in. from the core center. The flux is compared with similarly derived values from thermal-neutron fluxes prevailing near some Zircaloy-2 specimens exposed during HRE-2 run 17, and near others exposed during runs
