Breeder reactor - Energy Education

Breeder reactors are a type of nuclear reactor which produce more fissile materials than they consume. They are designed to extend the nuclear fuel supply for the generation of electricity, and have even been mistakenly called a potential renewable energy source. Breeder reactors certainly have the ability to make nuclear fuels quite ...

China's Nuclear Fuel Cycle - World Nuclear Association

China's Nuclear Fuel Cycle (Updated December 2018) China has become self-sufficient in most aspects of the fuel cycle. China aims to produce one-third of its uranium domestically, obtain one-third through foreign equity in mines and joint ventures overseas, and to purchase one-third on the open market.

Breeder Reactors - Thorium for Singapore

A breeder reactor is a nuclear reactor that generates new fissile material at a greater rate than it consumes such material. These reactors were initially (1940s and 1960s) considered appealing due to their superior fuel economy; a normal reactor is able to consume less than 1% of the natural uranium that begins the fuel cycle, whereas a ...

CNL Nuclear Review -

To ensure long-term nuclear energy security, it is advantageous to consider the use of externally driven sub-critical systems for producing fissile fuel to supply fleets of thermal-spectrum reactors as an alternative to using fast-spectrum or thermal-spectrum breeder reactors.

Fast Breeder Reactors - HyperPhysics Concepts

Fast Breeder Reactors Under appropriate operating conditions, the neutrons given off by fission reactions can "breed" more fuel from otherwise non-fissionable isotopes. The most common breeding reaction is that of plutonium-239 from non-fissionable uranium-238.

Energy multiplication and fissile fuel breeding limits of ...

On the other hand, availability of high quality nuclear fuel would make the use of such a complicated machine like fusion hybrid or an ADS hybrid obsolete, because, the same fuel can be used much simpler in conventional nuclear reactors with well known technology.

Radioactivity : Breeding

Breeding As if a motor would produce more fuel than it uses ... Ordinary motors need to be filled with fuel to produce energy. Nuclear Energy has a remarkable property: some nuclear reactors are designed to produce more fuel than it consumes.

Nuclear Breeding - Robert B. Laughlin

Research has shown that breeding in nuclear reactors can generate the same amount of power using less nuclear fuel (and more abundant fuel) than conventional reactors. Further, as breeders can reduce the risk of nuclear proliferation, they present a viable technology for power generation.

Spent nuclear fuel - Energy Education

After nuclear fuel goes through a reactor once, it is called spent fuel. This is a bit of a misnomer because there's still a fair amount of energy left in the fuel. Visually, spent fuel looks the same as the fuel that goes into the reactor as it is contained in fuel assemblies containing ceramic fuel pellets.

Thorium As Nuclear Fuel: the good and the bad

Thorium As Nuclear Fuel Thorium is a basic element of nature, like Iron and Uranium. Like Uranium, its properties allow it to be used to fuel a nuclear chain reaction that can run a power plant and make electricity (among other things).

What are examples of nuclear fuels? - Quora

One reason why thorium reactors have not made more progress in the past is that nuclear fuel breeding traditionally has been a very slow and capital-intensive process. For this reason, the DBI reactor is designed to be started-up using conventional nuclear fuels, with low enough capital and operating costs that it can compete with other conventional nuclear power plants and pay for its costs ...

What is a nuclear fuel cycle?

What is a nuclear fuel cycle? By Nick Touran, June 2009. Back-end help from Maru Morell-Gonzalez. A nuclear fuel cycle is the path that we put heavy atoms through in order to extract energy from them, starting at the day we find them and ending when their wastes …

Breeder reactor - Wikipedia

In LWRs, the fuel temperature influences the rate of nuclear breeding (the breeding ratio). In principle, the increase is the fuel temperature affects primarily the resonance escape probability, which is connected with the phenomenon usually known as the Doppler broadening (primarily 238U).

Nuclear power - Wikipedia

The nuclear fuel cycle begins when uranium is mined, enriched, ... actinides in the present inventory of nuclear waste while also producing power and creating additional quantities of fuel for more reactors via the breeding process. As of 2017, there ...

Fast Neutron Reactors | FBR - World Nuclear Association

A standing wave design would start the fission reaction in a small section of fuel enriched to 12% at the centre of the reactor core, where the breeding wave stays, and operators would move fresh fuel assemblies from the outer edge of the core progressively to the wave region to catch neutrons, while shuffling spent fuel out of the centre to the periphery. As the wave would be surrounded by ...

Conversion Factor - Breeding Ratio - Nuclear Power

Nuclear Fuel Breeding. The fuel breeding or fuel conversion plays a significant role in the fuel cycle of all commercial power reactors. During fuel burnup the fertile materials (conversion of 238 U to fissile 239 Pu known as fuel breeding) partially replace fissile 235 U, thus permitting the power reactor to operate longer before the amount of ...

Sustainable Clean Energy | Scalable & Multi|Purpose | …

Future evolution of IMSR ® technology could include use of spent nuclear fuel, "breeding" fuel cycles, and even thorium. With these iterations, IMSR ® nuclear power becomes near-infinitely sustainable as an energy resource, one that can meet the majority of global energy needs for many centuries.
