A heat transfer model applicable to the refuelling process for natural gas vehicles
This research presents a study of transient heat transfer phenomena taking place between a storage cylinder and the incoming gas during the cylinder charging process. A theoretical model of convective heat transfer between the gas and the cylinder is described. Experiments with the high pressure …

Dynamic Modelling and Optimization of Hydrogen Refuelling Stations and Their Integration with Renewable Microgrids
The transport sector generates more than 20% of global CO2 emissions, with road transport as the main contributor. The urgent need to reduce the environmental impact of mobility has promoted the development of sustainable vehicles, such us Battery Electric Vehicles (BEVs) and Fuel Cell Electric …

Neutronic characterization of a Molybdenum-99-producing CANDU fuel bundle and implications for reactivity-device worth and refuelling strategies
… of the MPB relevant to transient behaviour and refuelling, and compares the results to those of the SCB. This includes derivation of reactivity coefficients, incremental macroscopic cross sections for reactivity devices and refuelling strategies for the MPB. The evaluations are made using …

Nonlinear estimation for condition monitoring of advanced gas-cooled nuclear reactor cores
… using measurements obtained during routine core refuelling process. It has been demonstrated that Fuel Grab Load Trace (FGLT) data gathered during refuelling operations provides, through the magnitude of its friction component, information relating to the condition of the graphite bricks. …

Project complexity and how to effectively measure complexity in projects: the case of a refuelling outage in a nuclear power generating plant
… was employed, and the unit of analysis was the refuelling outage in a nuclear power generating plant. Focus group was adopted as a technique to gather information. A group of project managers with wealth of knowledge in refuelling outages were assembled. They were given the complexity assessment …

An evaluation of the net breeding capability of heterogeneously-fuelled pressure-tube heavy water reactors with the thorium fuel cycle
… variants of this configuration (differing on the refuelling scheme used in the blanket) were further investigated with instantaneous power simulations with 10 full power days of refuelling. Both variants were found to abide by the existing license limits on maximum bundle and channel power. The …

Machine learning techniques for the health monitoring of rotating machinery in nuclear power plants
… (examining responses during semi-regular refuelling events) is shown to correlate highly with the remaining useful life of a circulator unit which eventually underwent an unexpected failure, and provides a potential quantitative metric for preventing repeat instances.

Dispatchable Operation of Multiple Electrolysers for Demand Side Response and the Production of Hydrogen Fuel-Libyan Case Study
… the city that can be converted to hydrogen refuelling stations (HRSs). In 2015 all scenarios for both PEM and alkaline electrolysers were considered and were found to be able to partly meet the project aims but with high cost of hydrogen due to the high cost of system capital costs, low …

Creep and anelasticity of conventional and ODS steels
… and shut-down, due to operations of maintenance, refuelling, variations in demand and emergency stops. These conditions, characterized by removal of mechanical loads only or both mechanical loads and temperature, trigger a time-dependent recovery of the plastic strain accumulated during creep …

A technology impact forecasting framework for the comparative life cycle cost and carbon assessment of alternative bus fleets
… need for sufficient vehicle range, recharging/refuelling capabilities and similar passenger capacities to meet public service requirements. Bus operators would benefit from a tool that rapidly and clearly analyses the costs and benefits of technologies that could affect these economic, …
