Thorium is considerably more abundant than uranium in the Earth s crust so the use of thorium in power reactors has been considered since the start of nuclear energy in the 1950s Kazimi 2003 Thorium is said to be fertile rather than fissile as a quantity of Th 232 transforms into U 233 by absorbing neutrons within a reactor
1 Thorium Based Molten Salt Reactors • Thorium is far more common & cheaper than No enrichment energy wasted 232 Th is just a metal common in rare earth ores All Thorium is consumed no spent
Liquid Fluoride Thorium Reactors however offer safer nuclear technology and promise cheap efficient carbon neutral energy [1] Thorium is a fairly sustainable source the supply of thorium is estimated to be able to power the planet for another thousand years

The TMSR LF1 reactor in China is an experimental liquid fluoride thorium reactor It employs a fuel salt mixture and coolant salt which enable the utilization of thorium and uranium 235
The reactor a two megawatt liquid fuelled thorium molten salt reactor MSR is located in the Gobi Desert city of Wuwei in Gansu province and is operated by the Shanghai Institute of Applied
Thorium based molten salt reactors TMSRs have interesting characteristics and applications including thorium energy utilization hydrogen production at high temperature water free cooling and small modular design which accounts for 1 % of the total power generation Another 28 reactors with a total capacity of 29 GW e are under
Checks proliferation As thorium based power reactor fuel is a poor source for fissile material that can be used to make an explosive device illegally proliferation is said to be vastly curtailed by using these 233 which is present in the used thorium fuel It contains U 232 that can lead to a formation a strong gamma radiation field
Thorium also represents 200 times energy as is currently available from uranium reserves worldwide Although fast reactors GFR SFR LFR can make better use of uranium base fuel and its waste thorium fuel cycle provides better proliferation resistance with reduced long term radiotoxicity from transuranics
Thorium is a naturally occurring radioactive element that has been identified as a potential alternative fuel for nuclear energy production Additionally thorium based nuclear reactors have
An engineering scale facility Power Reactor Thorium Reprocessing Facility PRTRF was commissioned in January 2015 to reprocess the PHWR irradiated fuel bundles Wattal 2015 The salient units of PRTRF are shown in Fig 3 PRTRF will provide the much needed experience for setting up of larger capacity thorium fuel reprocessing facilities
Thorium reactors hold promise as an alternative for uranium in the there are about 440 nuclear power reactors operating in 32 countries plus Taiwan " providing about 10 percent of the world
The small modular thorium based molten salt reactor power station will be constructed and operated by the Shanghai Institute of Applied Physics Chinese Academy of Sciences
India is also working on developing thorium based nuclear power with a goal to have 30% of its power generated from thorium reactors by 2050 In the United States there are a few private
Thorium reactors are a fascinating prospect for the future of clean safer nuclear power with hopes of more efficient production Further research still needs to be completed and regulations surrounding the fuels must be implemented to limit proliferation

Companies developing thorium reactors or exploring thorium deposits are likely to see increased investor interest due to the potential for efficient and safer nuclear power production Investing in companies with strong positions in thorium technology or deposits can be a strategic move for long term growth
232 Th is the predominant isotope of natural thorium If this fertile material is loaded in the nuclear reactor the nuclei of 232 Th absorb a neutron and become nuclei of 233 half life of 233 Th is approximately minutes 233 Th decays negative beta decay to 233 Pa protactinium whose half life is days 233 Pa decays negative beta decay to 233 U that is very good
Several countries including India China and the United States have invested in thorium based research and development programs India s Advanced Heavy Water Reactor Project is dedicated to demonstrating the viability of thorium based fuel cycles China is also looking into thorium as is shown by its interest in MSR technology
The molten salt fast reactor MSFR was chosen by the Generation IV International Forum GIF in 2008 as a representative molten salt reactor fitting the Gen IV criteria [] because of its fast spectrum sustainability and waste minimization and the use of thorium as fertile element owing to its proliferation resistance [2 7] In such a homogeneous reactor the
