Neutron-neutron and neutron-photon correlations withFREYA [PDF]
EPJ Web of Conferences, 2017 For many years, the state of the art for modeling fission in radiation transport codes has involved sampling from average distributions. However, in a true fission event, the energies, momenta and multiplicities of emitted particles are correlated. The FREYA (Fission Reaction Event Yield Algorithm) code generates complete fission events. Event-by-event

Search for Neutron-to-Hidden-Neutron Oscillations in an Ultracold Neutron Beam
Physical Review Letters, 2023 Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing processes, neutron-to-hidden-neutron oscillations have been repeatedly tested with ultra-cold neutron storage and passing-through-wall experiments in the range of small ($δm<

Neutronics Analysis of the Current Core of the TRIGA Mark II Reactor Vienna
, 2010 This paper presents the part of PhD work performed at the TRIGA Mark II Vienna. A detailed three dimensional MCNP model of the reactor was developed. The neutronics library JEFF3.1 was applied to this model. The model was completed by employing the fresh

Development of Gd-Si-O dispersed 316L stainless steel for improving neutron shielding performance
Nuclear Materials and Energy, 2020 The low solubility of gadolinium (Gd) limits its application in iron-based neutron shielding alloys. In this study, a high content of Gd up to 7.87 wt.% was added into 316L stainless steel by mechanical alloying (MA) of Gd2O3 with 316L powder. Neutronics

Actionable workflows for fusion neutronics simulation.
Neutronics simulations are complex and typically require significant effort in setting up multiple pre- and post-processing steps, such as preparing data and geometry before the neutronics simulation can be carried out.
