Investigation of the fundamental constants stability based on the reactor Oklo burn-up analysis
, 2010 The burn-up for SC56-1472 sample of the natural Oklo reactor zone 3 was calculated using the modern Monte Carlo codes. We reconstructed the neutron spectrum in the core by means of the isotope ratios: $^{147}$Sm/$^{148}$Sm and $^{176}$Lu/$^{175}$Lu ...

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Investigation of the IAEA benchmark problem using MCNP code [PDF]
Arab Journal of Nuclear Sciences and Applications, 2019 The "IAEA PWR benchmark problem" was intended to draw some conclusions about the accuracy of the different neutronic calculation codes used in the routine deterministic reactor calculation. The objective of this paper is to test the MCNP code against previously obtained solutions to provide new reference solutions to the IAEA benchmark with Monte Carlo

Neutron-induced dpa, transmutations, gas production, and helium embrittlement of fusion materials
, 2013 In a fusion reactor materials will be subjected to significant fluxes of high-energy neutrons. As well as causing radiation damage, the neutrons also initiate nuclear reactions leading to changes in the chemical composition of materials (transmutation ...

Measurement of 139La(p,x) cross sections from 35–60 MeV by stacked-target activation [PDF]
, 2019 A stacked-target of natural lanthanum foils (99.9119% 139La) was irradiated using a 60 MeV proton beam at the LBNL 88-Inch Cyclotron. 139La(p,x) cross sections are reported between 35–60 MeV for nine product radionuclides. The primary motivation for this
