Application submitted for US molten salt research reactor (world-nuclear-news.org)

Article summary

A US university has submitted an application for a construction permit to build a 1 MWt molten salt research reactor. The reactor will be used for on-campus nuclear research and training opportunities. The application is the first of its kind in over 30 years and represents a significant step forward in the development of advanced nuclear technologies. The reactor is expected to be completed within 6-48 months after the issuance of the construction permit.

What commenters say

• The use of fluoride salt in molten salt reactors is due to its stability at high temperatures and ability to dissolve high concentrations of actinides and fission products.
• Some commentators believe that the development of molten salt reactors could lead to advances in nuclear weapons technology, while others argue that this risk is overstated.
• The proliferation of reprocessing technology is a concern, as it could potentially be used to divert plutonium for nuclear weapons production.
• Molten salt reactors have the potential to produce heat for hydrogen generation, which could replace fossil fuels in heating, transport, and industry.
• The regulatory process for licensing new reactor types is complex and may require updates to consider designs that deviate from common water-moderated types.
• Some commentators argue that the risk of nuclear proliferation is not a significant concern, as countries that already have nuclear weapons could potentially use other methods to produce fissile material.
• The development of molten salt reactors is still in its early stages, and significant research is needed to overcome technical challenges, including materials research and corrosion resistance.
• The use of thorium as a fuel source in molten salt reactors is seen as a promising area of research, but it is still in the early stages of development.
