Historical overview of nuclear data evaluation in intermediate energy region

Fukahori, Tokio

AIP Conference Proceedings 769, p.47 - 52, 2005/05

In recent years, intermediate energy nuclear data are required for various applications such as accelerator-driven systems for waste transmutation, spallation neutron sources, advanced cancer therapies, estimation of single event up set rate and dose on astronauts. For these requirements, many groups in the world continue intermediate energy nuclear data evaluation. The early stage of this evaluation was initiated in USA. For example, Pearlstein at Brookhaven National Laboratory produced systematics, modified ALICE code and evaluated proton and neutron nuclear data in late 1980s. At Lawrence Livermore National Laboratory, similar data developed for a medical application. Following them, many countries, such as Europe, Japan, Russia, China, Korea, started the preparation of nuclear data in this energy region. Overview of evaluation methods, results of evaluations are presented in comparison between experimental data and evaluated files, mainly JENDL High Energy File, as well as results from benchmark calculations.

Nuclear data evaluation for $$^{238}$$Pu, $$^{239}$$Pu, $$^{240}$$Pu, $$^{241}$$Pu and $$^{242}$$Pu irradiated by neutrons and protons at the energies up to 250 MeV

The evaluation of nuclear data for plutonium isotopes with atomic mass number from 238 to 242 has been performed. Neutron data were obtained at the energies from 20 to 250 MeV and combined with JENDL-3.3 data at 20 MeV. Evaluation of the proton data has been done from 1 to 250 MeV. The coupled channel optical model was used to obtain angular distributions for elastic and inelastic scattering and transmission coefficients. Pre-equilibrium exciton model and Hauser-Feshbach statistical model were used to describe neutron and charged particles emission from the excited nuclei. These evaluation is the first work for producing the full set of evaluated file up to 250 MeV for plutonium isotopes.

Neutron and proton nuclear data evaluation for $$^{235}$$U and $$^{238}$$U at energies up to 250 MeV

Basic features of nuclear data evaluation for uranium isotopes $$^{235}$$U and 238U at intermediate energies are described. The coupled channel optical model was used to obtain total cross section, reaction cross section, angular distributions and transmission coefficients. The direct, pre-compound and evaporation models were used to describe neutron and charged particles emission from excited nuclei. The neutron data evaluated were combined with JENDL-3.3 data below 20 MeV to obtain a full data set in the whole energy range between 10$$^{-5}$$ eV and 250 MeV. Evaluation of the proton data has been done at energies from 1 to 250 MeV
