Thorium / Molten Salt Reactor (MSR)

Our future energy supply must be safe, clean and affordable. The Molten Salt Reactor (MSR) is an innovative reactor design that closely meets these criteria.

NRG is a global leader in Molten Salt Reactor research and works closely with Molten Salt Reactor developers.

Safe and clean energy

Generating power using a Molten Salt Reactor closely meets the safety, waste, cost and CO2 standards that we expect of today’s energy technology. As long ago as the 1960s, the Molten Salt Reactor was shown to be possible in principle. Although research at the time was suspended because other demands were being placed on reactor technology, it has now been resumed internationally.

Research into molten salt at Petten

Research reactors such as the High Flux Reactor (HFR) at Petten are indispensable to the development of new reactor technology such as the Molten Salt Reactor. With the experiments that can be carried out in the HFR, molten salt technology can be shown to work just as the theory has predicted.

The research at Petten currently consists of molten salt irradiation, materials research, helium bubbling research, gamma irradiation and waste management.

A subsequent step in the research could be the development of a tube in which molten salt can be pumped around under representative conditions. The realisation of such a facility can be a decisive step forward for the international research into Molten Salt Reactors.
