Why are thorium reactors bad?

Why are thorium reactors bad?

Irradiated Thorium is more dangerously radioactive in the short term. The Th-U cycle invariably produces some U-232, which decays to Tl-208, which has a 2.6 MeV gamma ray decay mode. Bi-212 also causes problems. These gamma rays are very hard to shield, requiring more expensive spent fuel handling and/or reprocessing.

Is thorium cleaner than uranium?

Thorium is safer and more efficient to mine than uranium, thus making it more environmentally friendly. [5] The percentage of thorium found in its ore is generally greater than the percentage of uranium found in its ore, so it is more cost-efficient.

What are the cons of thorium nuclear energy?

Disadvantages of thorium reactors: High start-up costs: Huge investments are needed for thorium nuclear power reactor, as it requires significant amount of testing, analysis and licensing work. Also, there is uncertainty over returns on the investments in these reactors.

What type of nuclear reactor eats nuclear waste?

Elysium’s reactor is also a fast reactor. “[B]ecause it will be a fast reactor with a molten fuel, it will be able to use nuclear waste as a fuel and burn it up over time. A fast reactor has an unslowed neutron flux and needs no moderator, like the water in light water reactors,” King explains.

Can you burn nuclear waste in fast reactors?

Fast reactors are capable of destroying the longest-lived nuclear waste, transforming it to waste that decays to harmlessness in centuries rather than hundreds of millennia. Fast reactors typically use liquid metal coolants rather than water.

Is it legal to own thorium?

It’s not illegal to own a small amount of thorium metal and it can be obtained in certain processed forms – it used to be in gas lantern mantles for example – but you will require a license if the amounts are large enough or if you plan to make anything out of it.
