“…NJOY is a computer programme that translates ENDF-formatted nuclear data into ACE libraries for criticality and shielding applications [21,22]. In this study, ENDF-formatted libraries were utilised to build the requisite cross-section data files using NJOY [23][24][25][26].…”

The goal of the present work is to demonstrate the effects of adding uranium dioxide (UO2) to deuterium fuel in the fusion-fission hybrid reactions. The effectiveness of applying a reflector surface on the neutron yield in D-D and D-UO2 reactions has been investigated. The neutrons yielded from the fusion reactions were considered as a neutron source for fission reactions. For this purpose, MCNPX and its extension, the MCUNED code, for D-D fusion processes and UO2 fission reactions were used to calculate the neutron yield and the generated power. Using externally evaluated nuclear data libraries, MCUNED is capable of light ion transport. The D (d, n) 3He reaction with 0.25 gm of deuterium and the fission reactions with 0.25 and 1.0 gm of UO2 were utilized. The results showed that the calculated neutron flux from the D-D fusion reaction increased by a considerable amount when applying the reflector surface. Adding 1.0 gm of UO2 to deuterium fuel enhanced neutron flux by 4.95 times on average, outside the source with the reflector surface. The calculated power increased by about 3-folds when 1.0 gm of UO2 was added. Despite the narrow cross section of the D-D reactions used in this study, it was found that utilizing the reflector surface and UO2 or depleted uranium with restrictive high masses may be able to multiply the generated neutrons and the resulting power.

“…The particle transport calculations are done externally using the existing codes such as DOORS [16], DANTSYS [17], PARTISN [4], and the information on the direct and adjoint fluxes is passed to SUSD3D via the neutron flux moment files. Extensions to ADVANTG/DENOVO and DRAGON codes were also developed in the scope of PhD theses [18,19]. At present, the XSUN package supports only the interface with the PARTISN code.…”

A new version of the XSUN-2022 computer code package is under preparation to be released through NEA Data Bank which includes the latest updates of the SUSD3D sensitivity/uncertainty (S/U) code and the corresponding cross section and covariance matrix libraries based on the JEFF-3.3, ENDF/B-VIII.0 and FENDL-3.2 evaluations. The XSUN code package is a user–computer interface environment, written in Xbase++ ® and using Compiler 1.90.331 and Alaska 32-Bit Linker, for user-friendly pre- and post-processing of the input and output data for a complete and self-consistent set of deterministic codes. The flowchart integrates the codes TRANSX, PARTISN, and SUSD3D, all available from the OECD/NEA Data Bank and RSICC. The codes are used for the preparation of multigroup nuclear cross-section, neutron and gamma transport calculations for criticality and shielding calculations and nuclear data sensitivity and uncertainty calculations, respectively. XSUN-2022 is the 3rd released version, after XSUN-2013 and -2017.

“…The decades of experience with sensitivity studies in the nuclear data community suggest that critical advances can be made in space science through collaborative, cross-disciplinary efforts. Some of the existing sensitivity tools in the nuclear data community include: TSUNAMI, TSAR, SEN3, and SAMPLER (ORNL) (Perfetti and Rearden, 2013); Whisper and Crater (LANL) (Kiedrowski et al, 2015); Nuclear Data Sensitivity Tool (NDaST) (OECD NEA) (Dyrda et al, 2017); SUSD3D (JAEA/NEA) (Kos et al, 2021); NUSS-RF (PSI) (Zhu et al, 2015); FICST (McMaster University) (Mostofian, 2014); RMC (Tsinghua University) (Wang et al, 2014); and GPT-free in OpenMC (MIT/Purdue/Virginia Commonwealth University) (Wu et al, 2019). While many of these codes were designed specifically to determine the sensitivities of input nuclear cross sections on nuclear reactor performance (such as the effective neutron multiplication factor k eff ) and for nuclear criticality safety studies, some are more general and could potentially be adopted to address sensitivities critical for space research.…”

Understanding the harmful effects of galactic cosmic rays (GCRs) on space exploration requires a substantial amount of nuclear data. Specifically, the interaction of energetic GCR charged particles with spacecraft materials generates secondary radiations that, through energy deposition, can harm astronauts and electronic systems. By identifying the gaps in our knowledge of the relevant nuclear data—such as interaction cross sections—and identifying ways to fill those gaps—with measurements, compilations, evaluations, dissemination, reaction modeling, sensitivity studies, and uncertainty quantification—the safety and viability of space exploration can be improved. This work surveys the state of the art in this interdisciplinary field and identifies promising collaborative research topics that have significant potential to advance our understanding of the effects of the space radiation environment on space exploration.
