This is a hybrid event – face to face and webinar.
Of the six Gen IV reactor designs under study, Molten Salt Reactors (MSRs) are arguably one of the most exciting for their offering of enhanced safety and versatility in design and purpose. MSRs have a wide choice of:
- solid or liquid fuels,
- thermal or fast neutron spectrum operation
- fuel types: Pu-239, U-235 or U-233 (otherwise known as the
thorium fuel cycle)
- and choice of fluoride or chloride-based salts.
Much was learnt from the US molten salt reactor experiment, an 8 MW (th) thermal-neutron, liquid-fuel reactor that operated in Oak Ridge, Tennessee between 1965-1969. During its 11,500 hours of operation, much was learnt of the reactor’s characteristics, including its operational stability at high temperatures over prolonged periods.
Today, MSRs are being revisited by the US, Canada, China, UK and Russia, in multiple billion-dollar private-public ventures, some of which will become operational prototypes within the decade. This talk will cover both past and present developments in MSR designs.
