Abstract

Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors, critical fast reactors like Gen-IV systems, and other innovative reactor systems such as accelerator driven systems (ADS). In particular, 244Cm, 246Cm and 248Cm (244;246;248Cm) play an important role in the transport, storage and transmutation of the nuclear waste of the actual nuclear reactors, due to the contribution of these isotopes to the radiotoxicity, neutron emission, and decay heat in the spent nuclear fuel. Also, capture reactions in these Cm isotopes open the path for the formation of heavier elements such as Bk and Cf. Recent sensitivity studies have shown that the uncertainties in the evaluations of 244;246;248Cm in the resonance region are too big to obtain the desired uncertainties in the characterisation of the spent fuel of conventional nuclear reactors...
