Not exact matches

Coupling Reactor Types If advanced fast reactors come into use, they will at first burn spent thermal - reactor fuel that has been recycled using pyroprocessing.

It could be stashed away for future use as fast - reactor fuel.

An Outdated Strategy Early nuclear engineers expected that the plutonium in the spent fuel of thermal reactors would be removed and then used in fast - neutron reactors, called fast breeders because they were designed to produce more plutonium than they consume.

We understand that their first fast reactors will use oxide or carbide fuel rather than metal — a less than optimum path, chosen presumably because the PUREX reprocessing technology is mature, whereas pyroprocessing has not yet been commercially demonstrated.

Fast reactors can thus minimize the risk that spent fuel from energy production would be used for weapons production, while providing a unique ability to squeeze the maximum energy out of nuclear fuel.

Using a different reactor shape than ITER and, eventually, superconducting magnets, the company says it has a cheaper and faster path to an energy - producing fusion reaction.

The radioactive material was reprocessed by the French company Cogema in La Hague and will be used in Japan's fast - breeder nuclear reactor programme.

Rather than the pellets of uranium oxide used in other fast reactors and conventional reactors as fuel, GE would fabricate metal alloy fuels, with the plutonium or uranium mixed with zirconium metal.

One solution under consideration is to recycle the plutonium yet further — by using it as fuel in a pair of new, so - called «fast» reactors.

One attractive feature of fast reactors is that they can produce more fuel than they consume, avoiding the issue of the limited supplies of the uranium used in conventional nuclear reactors.

Novel design The trouble with fast reactors has largely been related to what's used to cool them — liquid sodium in the case of GE's PRISM and many others.

PRISM is a sodium - cooled, high - energy neutron (fast) reactor design that uses a series of proven, safe and mature technologies developed in the U.S. and abroad.

PRISM is a high energy neutron (fast) reactor which uses a series of proven, safe and mature technologies to create an innovative solution to dispose of used nuclear fuel and surplus plutonium.

This means that the bonus neutrons can be used to breed new fuel in fast breeder reactors.

Another good reason to use hexagons is that fast reactors can become more reactive when fuel is pushed closer together.

«Unlike today's nuclear reactor, the IFR [integral fast reactor] can generate unlimited amounts of inexpensive clean power for hundreds of thousands of years... It provides an excellent solution for what to do with our nuclear waste because it can use our existing nuclear waste for fuel and it is significantly more proliferation - resistant than other methods of dealing with nuclear waste... The IFR is also inherently safe.

An application case representative of an assembly of the low void effect sodium fast reactor ASTRID is used to study the physics of this kind of system, illustrating the interesting capabilities provided by this approach and highlighting new possible calculation schemes.

Fast reactors on a closed fuel cycle use nearly all the actinides fed into them, while low energy reactors use only around one percent of the fuel.

One fact that Loewen pointed out that enabled greater fuel use by the PRISM (or any fast spectrum reactor) is that all neutron cross-sections are one Barn.

«You get this beautiful synergy of using PRISM, a small modular reactor, to fix a [waste] problem and then explore if we could use this to make all this other electricity with the integral fast reactor approach,» he explains.

JAEA chairman Toshio Kodama said, «In addition to effectively utilizing the results of our research and development - including the results obtained through the development of Monju so far for future fast reactor development - we will contribute to the development of state - of - the - art fast reactors in Japan by making maximum use of the human resources and equipment, etc of this organization according to the established «fast reactor development policy».»

PRISM is a high energy neutron (fast) reactor design which uses a series of proven, safe and mature technologies to provide an innovative solution to disposition plutonium stockpiles and harness the remaining energy potential of used nuclear fuel and surplus plutonium.

«Now these fast reactors — they can use all that depleted uranium for fuel.

Each dollar spent on a new reactor buys about two to ten times less carbon savings and is 20 to 40 times slower, than spending that dollar on the cheaper, faster, safer solutions that make nuclear power unnecessary and uneconomic: efficient use of electricity, making heat and power together in factories or buildings («cogeneration»), and renewable energy.

The TWR is a liquid sodium - cooled fast reactor that uses depleted or natural uranium as fuel.

Fast neutron reactors are typically fuelled using a mixture of oxides of uranium and plutonium, and can vastly increase the efficiency of the nuclear fuel cycle by using the uranium - 238 recovered from recycling nuclear fuel after use in conventional nuclear power reactors.

And nuclear power is just as sustainable as any other power source — even if we only use conventional nuclear fast reactor designs, there is enough uranium in the oceans and on land (recoverable at prices that allow the fuel costs of fast reactors to remain the same as today — which is trivial) to last for 5 billlion years, the expected time remaining fo our sun.

Under previously announced plans, deployment of PWRs is expected to level off at 200 GWe by around 2040, with the use of fast reactors progressively increasing from 2020 to at least 200 GWe by 2050 and 1400 GWe by 2100.

http://www.world-nuclear-news.org/NP-China-plans-for-nuclear-growth-2011144.html Fast reactors — make maximum use of uranium resources by generating a certain amount more fuel than they consume — are seen as the main technology for China's long - term use of nuclear energy.

It compels the DOE to build an experimental fast reactor, using an experimental fuel, at a scale and power density that has never been demonstrated, on a rushed schedule, with insufficient funding.

(The DOE also is apparently considering a different fast reactor design that would use high - assay, low - enriched uranium fuel, but this material is in short supply and a new production source would have to be established.
