Times Cited Count:1 Percentile:10.69(Nuclear Science & Technology)The design of Accelerator Driven Systems (ADS) requires the development of simulation tools that are able to describe in a realistic way their nuclear performance and transmutation rate capability. In this publication, we present an evaluation of state of the art Monte Carlo design tools to assess their performance concerning transmutation of long-lived fission products. This work, performed under the umbrella of the International Atomic Energy Agency, analyses two important aspects for transmutation systems: moderation on Lead and neutron captures of Tc, I and I. The analysis of the results shows how shielding effects due to the resonances at epithermal energies of these nuclides affects strongly their transmutation rate. The results suggest that some research effort should be undertaken to improve the quality of Iodine nuclear data at epithermal and fast neutron energy to obtain a reliable transmutation estimation.

The International Atomic Energy Agency (IAEA) is conducting a Coordinated Research Project (CRP) on "Analytical and Experimental Benchmark Analyses of Accelerator Driven Systems". The paper summarizes results obtained for two of the benchmark exercises in the CRP, viz. the transmutation performance analyses of an Accelerator Driven System (ADS) and the analyses of long lived fission product transmutation rates (Tc, I).
