3. Breeder Reactor A breeder reactor is a nuclear reactor capable of generating more fissile material than it consumes [1] because its neutron economy is high enough to breed fissile fuel from fertile material like uranium-238 or thorium-232.nuclear reactorfissile materialconsumes [1]neutron economyfertile materialuranium-238thorium-232 In more recent decades, breeder reactors are again of research interest as a means of controlling nuclear waste and closing the nuclear fuel cycle.nuclear wastenuclear fuel cycle Fast breeder reactorFast breeder reactor or FBR uses fast (unmoderated) neutrons to breed fissile plutonium and possibly higher transuranics from fertile uranium-238. Thermal breeder reactorThermal breeder reactor use thermal spectrum (moderated) neutrons to breed fissile uranium-233 from thorium (thorium fuel cycle). Due to the behavior of the various nuclear fuels, a thermal breeder is thought commercially feasible only with thorium fuel, which avoids the buildup of the heavier transuranicsthorium fuel cycle

4. Thorium Fueled Reactor The thorium fuel cycle is a nuclear fuel cycle that uses the naturally abundant isotope of thorium, 232Th, as the fertile material. In the reactor, 232Th is transmuted into the fissile artificial uranium isotope 233U which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231Th), which are insufficient to initiate a nuclear chain reaction. Additional fissile material or another neutron source are necessary to initiate the fuel cycle.nuclear fuel cycleisotopethorium232Thfertile materialtransmutedfissileuranium233Unuclear fuelnatural uranium231Thnuclear chain reaction In a thorium-fueled reactor, 232Th absorbs neutrons eventually to produce 233U.neutrons This parallels the process in uranium breeder reactors whereby fertile 238U absorbs neutrons to form fissile 239Pu. The used nuclear fuel is formed into new nuclear fuel.breeder reactors 238U239Puused nuclear fuel

5. Thorium Advantages and Disadvantages Advantages: (1)thorium's greater abundance,greater abundance (2)superior physical and nuclear properties, (3)better resistance to nuclear weapons proliferation [1][2][3]nuclear weapons proliferation [1][2][3] (4)reduced plutonium and actinide production. [3]plutoniumactinide [3] Disadvanages (1) Startup fuel. Require a considerable amount of U-233 for the initial start up. Currently there is very little of this material available. (2) Salts freezing. The fluoride salt mixtures have high melting points, of 300 to over 600 degrees Celsius. (3) Beryllium toxicity. The proposed salt mixture FLiBe, contains large amounts of beryllium, a poisonous elementFLiBeberyllium (3) Radiation. primary fuel salt will produce highly radioactive fission products that produce a high gamma and neutron radiation field. (4) Waste management – Radioactive waste less suited long term storage form

6. Molten Salt Reactor Primary coolant, or even the fuel itself, is a molten salt mixture.coolantmolten salt MSRs run at higher temperatures than water-cooled reactors The nuclear fuel may be solid or dissolved in the coolant itself. The fluid becomes critical in a graphite core.criticalgraphite Molten-Salt Reactor ExperimentMolten-Salt Reactor Experiment (1965–1969) was a prototype for a thorium fuel cycle breeder reactor nuclear power plant.thorium fuel cyclebreeder reactornuclear power plant One Generation IV reactorOne Generation IV reactor design is a molten salt-cooled, solid- fuel reactor initial reference design is 1000 MW

16. Cold Fusion Chemical Fusion at room temperatures has been claimed in many experiments, but has never been duplicated

17. Low Energy Nuclear Reactions (LENR) Low Energy Nuclear Reactions (LENR) Lenr status The Strong Force Particle physicists have evidently been correct all along. "Cold Fusion" is not possible. However, via collective effects/ condensed matter quantum nuclear physics, LENR is allowable without any "miracles." The theory states that once some energy is added to surfaces loaded with hydrogen/protons, if the surface morphology enables high localized voltage gradients, then heavy electrons leading to ultra low energy neutrons will form-- neutrons that never leave the surface. The neutrons set up isotope cascades which result in beta decay, heat and transmutations with the heavy electrons converting the beta decay gamma into heat. - See more at: http://futureinnovation.larc.nasa.gov/view/articles/futurism/bushnell/lo w-energy-nuclear-reactions.html#sthash.3XTiklpB.dpuf Beta decay releases energy
