A unique design of this reactor is the distribution zone, which locates under the core and joins the core region with the inlet pipes of molten salt and coolant. Since the distribution zone has a major influence on the heat removal capacity in the core region, the thermal hydraulics characteristics of the distribution zone have to be investigated. This paper focuses on the thermal hydraulics analysis of the distribution zone, which is conducted by the numerical simulation using COMSOL Multiphysics with the CFD (Computational Fluid Dynamics) module and the Heat Transfer module. The energy loss and heat exchange in the distribution zone are also quantitatively analyzed. The velocity and temperature distributions of both molten salt and coolant at the outlet of the distribution zone, as inlet of the core region, are produced.

  • The Potential Impact of Molten Salt Reactors on the UK Electricity Grid
    The Potential Impact of Molten Salt Reactors on the UK Electricity Grid Charles Denbowa,b, Niccolo` Le Bruna, Niall Mac Dowella, Nilay Shaha, Christos N. Markidesa aDepartment of Chemical Engineering, Imperial College London, South Kensington Campus, London, SW7 2AZ bDepartment of Materials, Imperial College London, South Kensington Campus, London, SW7 2AZ Abstract The UK electricity grid is expected to supply a growing electricity demand and also to cope with electricity generation variability as the country pursues a low-carbon future. Molten Salt Reactors (MSRs) could offer a solution to meet this demand thanks to their estimated low capital costs, low operational risk, and promise of reliably dispatchable low-carbon electricity. In the published literature, there is little emphasis placed on estimating or modelling the future impact of MSRs on electricity grids. Previous modelling efforts were limited to quantifying the value of renewable energy sources, energy storage and carbon capture technologies. To date, no study has assessed or modelled MSRs as a competing power generation source for meeting decarbonization targets. Given this gap, the main objective of this paper is to explore the cost benefits for policy makers, consumers and investors when MSRs are deployed between 2020 and 2050 for electricity generation in the UK. This paper presents results from electricity systems optimization (ESO) modelling of the costs associated with the deployment of 1350 MWe MSRs, from 2025 onwards to 2050, and compares this against a UK grid with no MSR deployment. Results illustrate a minimum economic benefit of £1.25 billion for every reactor installed over this time period. Additionally, an investment benefit occurs for a fleet of these reactors which have a combined net present value (NPV) of £22 billion in 2050 with a payback period of 23 years if electricity is sold competitively to consumers at a price of £60/MWh.

Secondly, this paper highlights what we should know about the economics and financeof MSRs, suggesting a research agenda. The literature is very scarce and focuses on MSR overnight capital cost estimations and the comparison between MSR cost of electricity and other energy sources. Cost estimations need to be more transparent and independently assessed. Furthermore, there is no peer- reviewed literature on MSR financing, only claims from vendors. 1.

In the beginning of the 21st century, several research institutions and also private companies had proposed various design of thorium-based nuclear reactor, ranging from solid fuel to molten fuel, fast and thermal neutron spectrum and also various path of waste management. This paper studies 10 of the proposed reactor designs by 10 different organizations, three key aspects analysed quantitatively namely price per kilowatt, safety features and spent fuel managements. Corresponding factors contributing to the key aspects mentioned above were gathered, weighted based on evidence available and analysed using decision matrix. Based on the information collected, preliminary ranking were constructed based on trends between various factors. 1. Introduction 1.1. Thorium reactor developer of the 21st century Thorium fuel reactor was first developed by the Oak Ridge National Laboratory (ORNL) in 1950s, under the Aircraft Reactor Experimental (ARE) by Alvin Weinberg, then director of ORNL.
