Abstract: The aim of this research was to study the spallation reaction of a cesium-137 target using a beam of protons or deuterons for the transmutation of nuclear waste, as well as to evaluate the differences in the production cross-section of the secondary spallation products, such as neutrons, protons, deuterons, pions (π⁺, π⁻, π₀), helions, tritons, and alphas. The work presented in this paper provides the necessary scientific evidence for confidently implementing the MCNP-calculated transmutation of cesium-137 using a spallation reaction. In our research we evaluated and improvised the different physical characteristics of the fission products of the cesium-137 target during a spallation reaction.

Keywords: transmutation; waste energy; spallation; cesium-137; MCNP; cross section; Monte Carlo.
