Thorium As Nuclear Fuel: the good and the bad

Reactors that use thorium are operating on what's called the Thorium-Uranium (Th-U) fuel cycle. The vast majority of existing or proposed nuclear reactors, however, use enriched uranium (U-235) or reprocessed plutonium (Pu-239) as fuel (in the Uranium-Plutonium cycle), and only a handful have used thorium.

Uranium 235 consumption in a nuclear reactor

Uranium 235 consumption in a nuclear reactor. A typical thermal reactor contains about 100 tons of uranium with an average enrichment of 2% (do not confuse it with the enrichment of the fresh fuel, that is about 4%). For the reactor of power of 3000MW th determine the consumption of 235 U that must undergo fission each day to provide this thermal power. ...

Forum Post: 1 gram of uranium fuel produces the same ...

The US Nuclear Energy Institute suggests that for a coal-fired plant 78% of the cost is the fuel, for a gas-fired plant the figure is 89%, and for nuclear the uranium is about 14%, or …

Corrosion of Zirconium Alloys Used for Nuclear Fuel …

The nuclear fuel used in these reactors is in the form of fuel rods, which consist of long tubes (approximately 4 m long, with approximately 1-cm diameter and 0.6-mm wall thickness) made out of zirconium alloys and which contain uranium dioxide pellets. These tubes, termed the nuclear fuel cladding, constitute

THORITE (Thorium Uranium Silicate)

Thorite is the most common thorium mineral. Thorium is a highly radioactive element and could be used as a replacement for uranium in nuclear power generation. It is estimated to be three times as common as uranium and all the thorium in the Earth's crust could have more potential energy than both uranium and the fossil fuel reserves combined.

Nuclear Energy Vs. Fossil Fuel | Sciencing

Average total costs in mills per kilowatt-hour reported for 2017 are, in order of increasing cost, 10.29 for hydroelectric power (including both conventional hydroelectric and pumped storage hydroelectric plants), 24.38 for nuclear power, 31.76 for gas turbine and small scale (defined as gas turbine, internal combustion, photovoltaic or solar and wind plants) and 35.41 for fossil steam plants.

Future is not looking good for thorium nuclear reactors ...

 · Unsustainability, the current uranium cycle uses up what? 20 to 30% of the available uranium 235 before the fuel pellets deteriorates, swells, becomes ineffective with waste and nuclear poisons and must be replaced. Uranium 235, the reactor fuel is only 0.5 to 0.7 percent of natural uranium. The rest is U 238.

Why Nuclear Power is not an alternative to fossil fuels ...

Further, the study concludes that nuclear power is simply not efficient enough to replace fossil fuels, an endeavor which would require nuclear production to increase by 10.5% every year from 2010 to 2050-an "unsustainable prospect".

uranium | Definition, Properties, Uses, & Facts | Britannica

Uranium, radioactive chemical element of the actinoid series of the periodic table, atomic number 92. It is an important nuclear fuel. It is a dense, hard metallic element that is silvery white in color. It is ductile, malleable, and capable of taking a high polish. Learn more about uranium in this article.

67 – Understanding Why Nuclear Power Cannot Replace Fossil ...

 · To fuel a conventional 1 gigawatt nuclear power plant, approximately 163 metric tonnes of uranium is needed each year according to the World Nuclear Association. A new nuclear power plant is licensed for 60 years meaning each will need a 60-year supply of uranium to operate.

Nuclear Fuel Cycle

This brochure describes the nuclear fuel cycle, which is an industrial process involving various activities to produce electricity from uranium in nuclear power reactors. The cycle starts with the mining of uranium and ends with the disposal of nuclear waste. The raw material for today's nuclear fuel is uranium. It must be processed

APS Physics | FPS | Liquid Fuel Nuclear Reactors

Liquid Fuel Nuclear Reactors Today's familiar pressurized water nuclear reactors use solid fuel -- pellets of uranium dioxide in zirconium fuel rods bundled into fuel assemblies. These assemblies are placed within the reactor vessel under water at 160 atmospheres pressure and a temperature of 330°C.

Thorium fuel cycle

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.
