Radionuclide production using a fast flux reactor

The production of Sr-89, P-32.33, S-35 via the (n, p)-reaction, and Sn-117m , Gd-153 via the (n, gamma)-reaction using the BOR-60 fast flux reactor was experimentally studied. Test samples were irradiated in the active core of the BOR-60 reactor with fast neutron flux of 1 x 10(15) cm(-2)s(-1) for 40 -100 effective days. Gadolinium-153 was produced in a radial blanket cell, characterized by a modified ("softened") neutron spectrum. Data on target m aterials, procedure of irradiated target reprocessing, radionuclide yield, and specific activity are summarized in the report. The results of the expe riment showed that large-scale production of the radionuclides listed above is possible using a fast-flux reactor. (C) 2000 Elsevier Science Ltd. All rights reserved.
