Atom percent fission in uranium fuel (radiochemical method)

Journal Article · Thu Jan 01 04:00:00 EST 1981 · Annu. Book ASTM Stand.; (United States)

OSTI ID:5612426

The method covers the determination of U atom percent fission that has occurred in U fuel from analysis of the Cs-137 to U ratio after irradiation. The method is applicable to high-density, clad U fuel (metal, alloy, ceramic compound) in which no separation of Cs and U has occurred. The method is best applied to fuels that have aged several months since irradiation, to fuels where overheating has not caused center melting or grain growth, and to low-exposure samples in which the activity of Cs-134 is less than that of Cs-137.
