Uranium based nuclear energy is used
to produce ~20% of electricity in the
US
[1]

In the 1950’s scientist’s debated the
uranium and thorium based systems.
• Uranium light water reactors were easiest way to power a submarine
• Uranium nuclear waste can be used to make bombs
• Thorium is not easily weaponized and technology research was not continued.

Uranium vs. Thorium
[2]

Thorium is relatively abundant on the
earth’s crust
[3]

Uranium pressurized water reactors
account for a majority of the worlds nuclear
power plants

Other LFTR Advantages
• Less biologically harmful radioactive waste
• Radio active waste is toxic for only ~300 years
• Relatively cheap design

Issues converting to LFTRs
• Business model - not compelling to drastically change infrastructure and investments
• Converting the plant would be extremely expensive and still continue to produce waste (less amount)
• Corrosive salts damage system and will be costly to maintain

Development• China is currently investing in LFTR development
project and on pace to build a facility by 2020
• Europe abandoned development because of pressure from France’s uranium based nuclear power industry
