We describe and demonstrate an algorithm for mass minimisation of a fission-based space system.
N. Read, E. Shwageraus
Annals of Nuclear Energy (2023)
A new and perhaps more stable algorithm for burn-up calculations is proposed and numerically analysed.

Nuclear Science and Engineering (2022)
We accelerated source convergence in Monte Carlo eigenvalue calculations by performing multi-group transport (with cross sections generated on-the-fly).

Nuclear Science and Engineering (2022)
We simulated a British reactor which, at the time of its construction, could have had either a positive or a negative reactivity coefficient. At the time, this was determined only experimentally - modern simulation tools and multiphysics showed that the reactivity coefficients are indeed negative and we explain why.
S. Billiet, P. Cosgrove, N. Read
Nuclear Engineering and Design (2022)
The stability of several common burn-up algorithms is analysed. This includes using realistic Bateman operators (namely CRAM) and chains of nuclides. This reveals several phenomena which had been noticed in simulations previously but had no easy justification.
P. Cosgrove, E. Shwageraus
Journal of Computational Physics (2022)
This paper introduces our Monte Carlo code and the design decisions behind it. We’ve come a long way since then.

Journal of Nuclear Engineering (2021)
A simple trick is proposed to speed-up ray tracing in nested constructive solid geometries. This gave up to a 20% speed-up on finely discretised LWR problems.
M.A. Kowalski, P. Cosgrove
Annals of Nuclear Energy (2021)
We allow different energy fidelities in different areas of a Monte Carlo geometry. We demonstrate that the continuous energy region can suffer only a small accuracy penalty while gaining a substantial speed-up.
