MEASUREMENT OF THE STORED ENERGY OF NaCl AFTER REACTOR IRRADIATION

N.M. Hennen

Open publisher page 0 citations

Abstract

The increase of the internal energy of NaCl was measured by the difference of the salt heat of solution before and after reactor irradiation at 70 to 90 nif- C. The stored energy shows, as a function of the irradiation dose, divisible stages with a maximum of 1.1 cal/g NaCl. The possible mechanism was discussed and an estimation of the defect concentration was made. From the isothermal increase of the radiation damage, an activation energy of 1.18 ev and a reaction degree of the first order were determined for the temperature range 160 to 203 nif- C and discussed.
