“…The evaluated nuclear data library JENDL-4.0/HE [25] for proton and neutron energies up to 200 MeV should be incorporated into the PHITS package in order to improve the accuracy of particle production particularly with energies below 100 MeV, and interactions of particle with lighter targets such as Li and Be targets. To better calculate neutron production from photonuclear reactions, the JENDL Photonuclear Data file (JENDL/PD) [57] is also desirable to be incorporated in the PHITS package. Improvement of the GEM model is also regarded so that it describes nuclide production in the fission.…”

We performed a benchmark study for 58 cases (22 cases reported in this paper and 36 cases reported in online as supplementary materials of this paper) using the recent version (version 2.88) of the Particle and Heavy-Ion Transport code System (PHITS) in the following fields: (1) particle production cross-sections for nuclear reactions from 20 MeV to 1 GeV, (2) thick-target neutron yields and neutron shielding, (3) depth-dose distribution in water using 12 C beam, and (4) electron and photon transportation over a wide-energy range from keV to GeV. Overall agreements were found to be sufficiently satisfactory; however, several discrepancies are observed, particularly in particle productions with energies below 100 MeV, neutron production for 7 Li(p,n) 7 Be, and photonuclear reactions. To overcome these inaccuracies and to further improve the code, it will be necessary to incorporate a high-energy version of the evaluated nuclear data library JENDL-4.0/HE and the photonuclear data file JENDL-PD in the PHITS package.

“…This IAEA library was used in the present work. For the major uranium isotopes of 235 U and 238 U, we employed parts of evaluated data in the JENDL photonuclear data 2004(JENDL/PD-2004), 10) which has stored complete delayed neutron emission data including a yield along with relative abundances, decay constants and energy spectra for six precursor groups, due to the photofission of these nuclides.…”

A conceptual design study has been carried out with a Monte Carlo transport code on an active nondestructive assay system for low-level uranium-bearing wastes discharged from an uranium enrichment plant. Delayed neutrons from photofissions of uranium isotopes in the steel waste are counted with this system to confirm that the activity concentration of uranium in this waste is below the clearance level. The present design work needs a coupled neutron/photon transport code which can simulate the photonuclear reaction and the resultant emission of neutrons. We have modified a continuous-energy Monte Carlo transport code MVP to equip it with a function to simulate the emission of photoneutrons along with the delayed neutrons from the photofissions. The photonuclear data library for the modified MVP code was prepared on the basis of evaluated photonuclear data by IAEA. For the 235 U and 238 U, we employed evaluated data in the JENDL photonuclear data 2004, which stores complete delayed neutron emission data for these nuclides. With this code system, a time-dependent simulation of neutron counts was made for the assay system, which consisted of a 15 MeV end-point bremsstrahlung photon source, helium-3 neutron detectors and the waste. The present paper describes the modification to the MVP code and the results of design study.

“…The cross-section data libraries used in the MCNP5 calculations are EL3 [7] for electron-photon cascade reactions, MCPLIB04 [7] for photon interactions, FSXLIB-J33 [8] for neutron reactions, and LA150 [7] and JENDL/PD-2004 [9] for photonuclear reactions. Nuclides included in the photonuclear libraries for the target and assembly materials are 12 In the MCNP5 calculation, an electron beam is injected normally to the copper target fixed 20 cm behind from the beam line, as shown in Figure 1.…”

Following the angular distribution measurements of bremsstrahlung photons and photoneutrons, we measured the distributions of photon and neutron dose rates in the iron and concrete assemblies using a copper target bombarded by 18, 28 and 38 MeV electrons at the electron linear accelerator (linac) of Hokkaido University. In this experiment, seven types of shielding assemblies of iron and concrete layers were used and the photon and neutron dosemeters were inserted into the assemblies to get the depth-dose distribution. The measured results were compared with the results calculated using the Monte Carlo code MCNP5 to verify the calculated results. The calculated results of the ambient dose equivalent rates were in agreement with the measured results within 30% accuracy. Since no work on the radiation behavior in the shielding wall of medical linac room has ever been reported, this work gives valuable benchmark data for the detailed shielding design with high accuracy.
