The reducing cost of solar and wind energy together with the UK commitments to net-zero emissions will mean that systems for 2050 similarly those in many other countries be dominated by variable renewable supplies. Electricity are expected very reliable but is inherently intermittent. We explore storage as a solution this problem, considering physics system gain understanding its needs, rather than using economics, which may lead less adequate designs. scale periodic nature problem crucial...
Over the last decade, importance of Monte Carlo as a neutron transport calculation method has greatly increased. This paper describes particle framework SCONE, which aims to provide with easy-to-learn environment for graduate students learn about methods and explore new ideas. The lists steps taken enhance user experience SCONE briefly discuses how architecture supports its goals. current version code is compared against Serpent shown sufficient accuracy be used teaching proof-of-concept...
The Random Ray Method (TRRM) is a recently developed approach to solving neutral particle transport problems based on the of Characteristics. While method previously has been implemented only in closed-source or limited-functionality codes, this work describes its implementation two open-source Monte Carlo codes: OpenMC and SCONE. random ray implementations required small modifications existing Multigroup (MGMC) solvers, offering rare venue for redundant, fine-grained, "apples-to-apples"...
The neutron noise equation contains a fixed source term where the angular flux is present. Deterministic solvers have tended to solve for and store this in preprocessing step. This can be substantial memory burden as function of space, energy, angle. limit these smaller problems obtainable resolution. paper proposes solving standard eigenvalue transport simultaneously, reducing footprint while making frequency-domain method characteristics practical. approach demonstrated using random ray...
Thirty years after the first PHYSOR was held in Marseille, France, Universities of Cambridge and Birmingham collaborated to host PHYSOR2020 historic city celebrate three decades outstanding research field nuclear reactor physics.Over 400 papers were accepted for publication a diverse range topics, with special sessions planned on CORTEX project, fusion, global innovation, small modular reactors.Due COVID-19 situation worsening between late February early March 2020, official government...
Abstract The objective of this paper is to quantify the coupling effect on power distribution sodium-cooled fast reactors (SFRs), specifically European SFR. Calculations are performed with several state-of-the-art reactor physics and Multiphysics codes (TRACE/PARCS, DYN3D, WIMS, COUNTHER, GeN-Foam) build confidence in methodologies validity results. Standalone neutronic calculations were generally excellent agreement a reference Monte Carlo-calculated (from Serpent). Next, impact coolant...
Fluoride-salt-cooled High-temperature Reactors (FHRs) are a variant of nuclear reactor offering high power densities and operating temperatures. This paper proposes new design stream FHR, leveraging developments experience from the British Advanced Gas-cooled Reactor (AGR) fleet, only commercial fleet high-temperature reactors to-date. The space for proposed AGR-like FHR is explored using thermal-hydraulic simulation optimisation package, seeking to maximise reactor's economic performance....
It was recently argued by Kemp et al. that HALEU (high-assay low-enriched uranium, or uranium enriched up to 19.75\%) can conceivably be used produce a nuclear weapon and on this basis civilian enrichment limits should lowered 10% 12%. We find their argument unconvincing in several respects.
A new variance reduction technique for Monte Carlo transport methods is investigated. This approach based on non-parametric bootstrapping, a statistical inference and resampling method which used to generate simulated samples of scores estimate the properties underlying integral response distributions. It also quantify uncertainty corresponding estimates as well any bias introduced by then can be corrected. In this context, bootstrapping first second-order moments estimations responses...
