To better understand the industrial and political contexts of nuclear innovation, it is necessary to consider the history of nuclear fission technologies (four generations of nuclear power plants): (1) GEN I (construction 1950–1970): early prototypes, using mainly natural uranium as fuel, graphite as moderator, and CO2 as coolant (built at the time of “Atoms for Peace,” 1953); (2) GEN II (yesterday, construction 1970–2000): safety and reliability of nuclear facilities and energy independence (in order to ensure security of supply); (3) GEN III (today, construction 2000–2040): continuous improvement of safety and reliability, and increased industrial competitiveness in a worldwide growing energy market; (4) GEN IV (tomorrow, construction from 2040): for increased sustainability (optimal utilization of natural resources and waste minimization) and proliferation resistance. The focus in this paper is on the design objectives and research issues associated to the latter generation IV. Their benefits are discussed according to a series of ambitious criteria or technology goals established at the international level (generation IV international forum (GIF)). One will have to produce not only electricity at lower costs but also heat at very high temperatures, while exploiting a maximum of fissile and fertile matters, and recycling all actinides, under safe and reliable conditions. Scientific viability studies and technological performance tests for each system are being carried out worldwide, in line with the GIF agreement (2001). Their commercial deployment is planned for 2040. In Sec. 6, it is shown to what extent GEN IV can be considered as a beneficial, responsible, and sustainable response to the societal and industrial challenges of the future low-carbon economy.

The MOX fuel is made of a mixture of Pu and depleted U oxides (the U that results from enrichment operations is depleted in the isotope 235).
Front end of the fuel cycle: in particular, uranium purchase (e.g., Shinkolobwe mine in Katanga, Congo), conversion and enrichment as well as fuel fabrication (Belgonucléaire, capacity of up to 150 tons U/year in 1971).
Back end of the fuel cycle, in particular, nuclear fuel reprocessing (Eurochemic plant in Dessel, a joint OECD project that operated from 1966 to 1974) and geological disposal (HADES). In 1974, a R&D program was started on waste storage in deep geological clay formations. In 1980, the construction of HADES was started (High Activity Disposal Experimental Site) at SCK-CEN Mol, a laboratory at a depth of 225 m, to perform hydrogeological and physicochemical research.

MYRRHA is the result of an international collaboration at SCK-CEN, Mol: it is an ADS of 800 MWth, loaded with several tons of TRUs and coupled with a 30 MW proton accelerator. It will be able to transmute up to 250 kg HM/year of MAs, which corresponds to the amount of MAs produced in 10 LWR units of 1 GWe.

“Right after shutdown the heating rate of the reactor is about seven percent of the full power rate, and then as the radioactivity decays away, the decay heat decreases; in a few hours it is less than 1%, and it keeps going down. Even one percent of full power is a lot of heat, and if you don't remove that heat it's surely enough to overheat the fuel and melt it, and therein lies the problem that the reactor safety analyst must face—to assure himself that the heat produced by these decaying fission products is reduced, is removed for periods of weeks or months… Reactor Safety Study (WASH-1400)/(commonly known as the Rasmussen Report) published by the US Nuclear Regulatory Commission 1974,”
