Determination of the residual thermal power in spent nuclear fuel from gamma-ray measurements
1996 (English)Report (Other academic)
A method of determining the decay heat in spent nuclear fuel using the gamma radiation from 137Cs is presented. The method is useful for fuel assemblies with a cooling time longer than 5 years. Experimental tests of the method are presented for eleven 8x8 BWR fuel assemblies with cooling times in the range 5 to 15 years. The decay heat is determined with a 3.5 % error for these assemblies. Simulations with the code Origen2.1 shows that this uncertainty can be expected to be reduced for fuel assemblies with cooling times of the order of 40 years.
