Lead cooled fast reactor



  The Lead-cooled Fast Reactor is a Generation IV reactor that features a fast neutron spectrum, molten thermochemical production of hydrogen.

Modular nuclear reactors

The LFR battery is a small factory-built turnkey plant operating on a closed fuel cycle with very long refueling interval (15 to 20 years) cassette cores or replaceable reactor modules. Its features are designed to meet market opportunities for electricity production on small grids, and for developing countries that may not wish to deploy an indigenous fuel cycle infrastructure to support their nuclear energy systems. The modular "battery" system (ie consisting of a number of identical elements, not "battery" in the sense of an electro-chemical energy storage system), is designed for distributed generation of electricity and other energy products, including hydrogen and potable water.

Application

LFR reactors OK-550 and BM-40A, capable of producing 155 MW of power, have been applied on soviet Alfa class submarines. They were significantly lighter than typical water-cooled reactors and had an advantage of being capable to quickly switch between maximum power and minimum noise operation modes, but lacked reliability, as solidifying of lead-bismuth solution turned the reactor inoperable.
