Abstract. The criticality safety benchmark calculations with the RTS&T general purpose Monte Carlo code were extensively used to validate the 233,235 U and 239 Pu evaluated data files. The benchmarks employed are from the International Criticality Safety Benchmark Evaluation Project (ICSBEP). We have performed calculations using the newly evaluated data files from ENDF/B-VII.0 and special purpose Minsk Actinides Library. The influence of the prompt fission neutron spectra of major actinides on the k eff for the selected fast spectrum benchmarks is investigated.

Compact D-D/D-T neutron generators and their applications

Neutron generators based on the 2 H(d,n) 3 He and 3 H(d,n) 4 He fusion reactions are the most commonly available neutron sources. The applications of current commercial neutron generators are often limited by their low neutron yield and their short operational lifetime. A new generation of D-D/D-T fusion-based neutron generators has been designed at Lawrence Berkeley National Laboratory (LBNL) by using high current ion beams hitting on a self-loading target that has a large surface area to dissipate the heat load. This thesis describes the rationale behind the new designs and their potential applications. A survey of other neutron sources is presented to show their advantages and disadvantages compared to the fusion-based neutron generator. A prototype neutron facility was built at LBNL to test these neutron generators. High current ion beams were extracted from an RF-driven ion source to produce neutrons. With an average deuteron beam current of 24 mA and an energy of 100 keV, a neutron yield of >10 9 n/s has been obtained with a D-D coaxial neutron source.
