M. Ragheb - Energy production by fast breeding remains the main goal of the Liquid Metal Fast Reactor (LMFR) to ensure a sustainable long term fissile fuel supply. In addition, the use of LMFRs allows the recycling of the Minor Actinides content of nuclear waste burning them to produce energy and reduce the amounts of disposed waste. Another advantage of the LMFR is its higher thermal efficiency compared with water-cooled reactors.
Unless new sources of energy are found, the development of nuclear power will necessarily depend on fast reactors.The choice of coolant determines the main design approaches and the technical and economic characteristics of a nuclear power plant. Historically, this requirement has been met by the use of sodium in nearly all fast reactors constructed and operated. The Generation IV International Forum (GIF) identified three fast reactor concepts for potential future development: SFR, sodium fast reactor, LFR, lead fast reactor and GFR, gas fast reactor.An objective is to identify important differences between sodium and other fast reactor coolants (lead/LBE and helium) and why sodium is preferred.
The depleted uranium from the enrichment program can power all of the electrical energy needs of the United States for over 700 years at 1994 levels. This is using fast reactor and spent fuel recycling technologies developed at Argonne National Laboratory.
Evolution of Liquid Metal Reactor: Integral Fast Reactor (IFR) Concept (Charles Till & Yoon Chang) USofA19.Feb.2015
Charles Till and Yoon Chang describe the evolution of the Liquid Metal Reactor, the development of the Integral Fast Reactor. This is a key step to providing plentiful energy for the world for a very long time.
