The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material.In the reactor, 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel.Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231 Th), which are insufficient to initiate a nuclear chain reaction.
Thorium abundance, its physical, chemical and neutronic properties were evaluated in comparison to the uranium fuel cycle to determine thorium fuel sustainability for next generation nuclear industry.
The thorium-based fuel implementation strategy fits in with the government’s policy and can pay for the front-end fuel cycle facilities by saving on fuel cycle costs and re-fuelling outage costs. The proposed strategy can help the country to become fuel-independent, help Eskom (the current nuclear operator in South Africa) to keep the power on for longer periods and create local job ...

The thorium fuel cycle is the path that thorium transmutes through from fertile source fuel to uranium fuel ready for fission.Th-232 absorbs a neutron, transmuting it into Th-233. Th-233 beta decays to Pa-233 and finally undergoes a second beta minus decay to become U-233. This is the one way of turning natural and abundant Th-232 into something fissionable.
In the right reactors (such as a liquid fluoride thorium reactor, or LFTRs) estimates say one ton of Th-232 can give us as much energy as 35 tons of uranium, which wastes 99% of fuel in modern ...
Liquid fuel MSRs utilizing the thorium fuel cycle have many safety, economic, and environmental advantages. [3] Because their reactor cores are much smaller and more compact, they are less expensive to produce. They do not need to shut down for refueling and their fuel lifetime is not limited by radiation damage.
Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.According to proponents, a thorium fuel cycle offers several potential advantages over a uranium fuel cycle—including much greater abundance of thorium on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production.

Conceptual core analysis of long life PWR utilizing thorium-uranium based fuel has conducted. The purpose of this study is to evaluate neutronic behavior of reactor core using combined thorium and enriched uranium fuel. Based on this fuel composition, reactor core have higher conversion ratio rather than conventional fuel which could give longer operation length.
Thorium fuel cycles have many incentives such as the reduction of plutonium generation and consumption of LWR actinides, the provision of high performance burnup, and the conservation of …

And then there is thorium. Power generation from a thorium isotope is accomplished by the fission of U-233 which is derived from the relatively stable, safer, and more abundant thorium. Given these benefits it has been conceptualized as a possible fuel for use in automobiles.

1-6-2020· One of the commonly studied configurations for thorium reactors is the seed-blanket configuration as shown in Fig. 1, which is also known as Radkowsky thorium fuel concept (Radkowsky and Galperin, 1998, Nuclear Energy Agency, 2015).Radkowsky embarked on a completely different core layout utilizing special multiple seed-blanket arrangements.
The thorium fuel cycle (shown above) starts with the transmutation of 232 Th into 233 U through a series of decays. 233 U goes on to play the role of nuclear fuel in these reactors. The thorium fuel cycle also produces plutonium, but the non-weaponizable isotope (plutonium-238).

"Thorium dioxide melts at 550 degrees higher temperatures than traditional uranium dioxide, so very high temperatures are required to produce high-quality solid fuel," says a report from the Oak ...
Because thorium doesn’t lend itself for making bombs, and in general has very limited commercial uses, research into thorium was given short shrift for decades. Before we begin to explore how we can use thorium as a nuclear fuel, here is some background information.
According to proponents, the thorium fuel cycle offers several potential advantages over a uranium fuel cycle, including thorium’s greater abundance, better physical and nuclear properties (e.g. lower capture-to-fission ratio for thermal neutrons), reduced plutonium and actinide production, and better resistance to nuclear weapons proliferation when used in traditional light water reactors.
A nuclear fuel includes uranium dispersed within a thorium hydride matrix. The uranium may be in the form of particles including fissile and non-fissile isotopes. Various hydrogen to thorium ratios may be included in the matrix. The matrix with the fissile dispersion may be used as a complete fuel for a metal hydride reactor or may be combined with other fuels.
thorium fuel cycle option, including ADS, in Member States [9]. The initial enthusiasm on thorium fuels and fuel cycles was not sustained among the developing countries later, due to new discovery of uranium deposits and their improved availability. However, in recent times,
thorium fuel cycle as a whole has never been fully developed. Today, the opportunities and challenges that could arise from the use of thorium in the nuclear fuel cycle are still being studied in some countries and in the context of diverse international programmes
A series of three IAEA meetings on utilization of thorium fuel were held in Vienna over a period of three years, 1997–1999: x Advisory Group Meeting on Thorium Fuel Cycle Perspectives, Vienna, 16– 18 April 1997. x Advisory Group Meeting on Thorium Fuel Utilization: Options and Trends, Vienna, 28– 30 September 1998.
The first thorium fuel specimens were loaded into the Norwegian fuel-testing reactor operated by the Institute for Energy Technology in Halden in April 2013, and the second round were loaded in December 2015. Both rigs were intended to verify test results and are considered a further step towards commercializing thorium as a supplement fuel in conventional nuclear reactors.
Abstract. Use of the thorium fuel cycle for nuclear power generation has been considered since the very start of the nuclear power era. In spite of a large amount of research, experimentation, pilot-scale and prototypic-scale installations, thorium fuel has not been adopted for large-scale power generation (Loewenstein and Sehgal in Trans Am Nuclear Soc, 27:312, 1977 []; Sehgal in The ...
