Integral Fast Reactor
The Integral Fast Reactor (IFR) is a revolutionary reactor design concept developed at Argonne
National Laboratory. The IFR is a
reactor fueled by metal alloy and cooled by liquid sodium. On
April 3, 1986, two tests demonstrated the inherent safety of the IFR concept. These tests
simulated accidents involving loss of coolant flow. Even with its normal shutdown devices disabled,
the reactor shut itself down safely without overheating anywhere in the system.

Integral Fast Reactor
The Integral Fast Reactor (IFR) is a fast reactor system developed at Argonne National Laboratory
in the decade 1984 to 1994. The IFR
project developed the technology for a complete system; the reactor, the entire fuel cycle,
and the waste management technologies were all included in the development program. The reactor
concept had important features and characteristics that were completely new and fuel cycle and
waste management technologies that were entirely new developments. The reactor is a “fast” reactor – that
is, the chain reaction is maintained by “fast” neutrons with high energy – which
produces its own fuel. The IFR reactor
and associated fuel cycle is a closed system. Electrical power is generated, new fissile fuel
is produced to replace the fuel burned, its used fuel is processed for recycling by pyroprocessing – a
new development – and waste is put
in its final form for disposal. All this is done on one self-sufficient site.
The IFR’s history is embedded in the history of nuclear power in the United States – in its ups and downs, and in the plusses and minuses of nuclear technology itself. Its story starts sixty years ago with the first reactor that ever produced useful electrical power. IFR development began in 1984 with the “advanced reactor development program” that was carried out for a decade at Argonne. Although the program was nearly complete in 1994, US President Bill Clinton announced in his State of the Union address that year that, ‘We are eliminating programs that are no longer needed, such as nuclear power research and development’, and the IFR, as the nation’s principal such program, was cancelled. But it continues at a low level in studies and programs of the US Department of Energy and in programs around the world today, due to its ability to provide a truly inexhaustible energy technology for entire nations.
