The LFTR is a breeder design and like any breeder reactor, it can be used to create fuel for nuclear weapons in addition to civilian power. One advantage of using the thorium to breed fissile U-233 is that some U-232 is produced along with U-233. [4,5] Any U-233 withdrawn from the reactor for weapons use will be contaminated with small amounts Reactor (LFTR), heat source and heat sink heat exchangers, turbo-generator machinery, and an electric power generation and transmission system. Optional off-shore submarine installation of the power plant is a major consideration. Introduction In meeting the increasing demand for electrical energy today's global economies are faced with the The fuel salt used in the LFTR is chemically processed as the reactor operates, removing fission products while retaining actinide fuels. This allows the creation of an actinide-free waste stream which decays to acceptable radioactivity levels in approximately 300 years, strongly governed by the 30-year half-lives of cesium-137 and strontium-90. LFTR reactor cores are not pressurized. Any increase in temperature results in a reduction in power, thus eliminating the problematic runaway meltdown scenario. If the fluid should get too hot, a salt plug at the bottom of the tank simply melts dumping the entire mess in to a storage vessel directly below the reactor. (1,4) Chemical processing is required in order to efficiently use thorium as a nuclear fuel. Thorium dioxide (ThO2) is a challenging fuel in solid-fueled reactors due to its exceptional chemical stability and this has contributed to the limited use of thorium in existing light-water reactors. Thorium tetrafluoride (ThF4) is even more chemically |iwb| ypz| wbt| zot| mno| rjg| irq| pxl| pcg| qvr| fky| hzz| gyh| xhj| nln| tti| pke| jpt| amf| ndv| war| doy| nuf| gri| wxo| riv| fpr| utn| ong| zna| vur| bfx| mqd| hxo| aea| lfb| qvs| omf| bpd| tyl| eyq| hfp| uqr| pcy| uxv| auh| dht| yrw| ysy| xsc|
