Talk:Thorium-based nuclear power

Huge and direct self-contradiction in the page

"Not suitable for bombs. It is difficult to make a practical nuclear bomb from a thorium reactor's by-products"

Later:

'Harvesting weapons-grade plutonium. The thorium fuel cycle is a potential way to produce long term nuclear energy with low radio-toxicity waste. In addition, the transition to thorium could be done through the incineration of weapons grade plutonium (WPu) or civilian plutonium."

even later:

"The decay of the protactinium-233 would then create uranium-233 in lieu of uranium-232 for use in nuclear weapons"

This says it is possible and suitable in a great and several ways to produce products for a nuclear bomb. 2003:C1:B720:C800:D565:433:BA0C:399B (talk) 06:40, 25 June 2024 (UTC)

No. A suitable process is needed to turn u-233 into weapons material. For far-more relevant materiel, see Plutonium-239. The refinement processes were the purpose of the Manhattan Project. -- Ancheta Wis   (talk | contribs) 12:34, 26 June 2024 (UTC)

This article needs a better introduction

This article doesn't give a good, brief, basic, explanation of a thorium reactor in the introduction but instead starts with a discussion of fuel and other details. Could someone please fix that? Mondebleu (talk) 14:40, 24 September 2024 (UTC)

This will take several editorial passes. There are multiple factors involved. The Generation IV reactors are a large list. In this list the molten-salt reactors (MSRs):

1. Nuclear reactors have historically been uranium-based, which historically operate at lower temperatures, so that working pressures for uranium-based reactors power generation are higher than for thorium-based molten salt reactors, which can safely operate at lower working pressures and higher working temperatures.
2. Thorium is more abundant than uranium, but thorium has been ignored because thorium is not as easy to weaponize.
3. It still takes consumption of a little uranium or plutonium to start the generation of neutrons for the nuclear reaction. But the neutron generation process in a molten-salt thorium reactor can be self-sustaining when the appropriate elements are filtered out during processing.
4. The high-temperature reactors could even consume weapons-grade material but would require inspection to detect any diversion into plutonium production.
5. Ultimately reprocessing by specialized centers is needed, but in far less volumes than conventional power generation.

For pebble bed reactors (PBRs)

1. Thorium can be used but the tennis-ball sized TRISO pebbles are usually made with uranium.
2. The working fluid is an inert gas. The operating temperature of the working fluid is higher than that of a molten salt reactor. Cooling of the reactor is by the working fluid.
3. The reaction is once-through, and the pebbles are not as easily reprocessed as molten fuels due to the silicon carbide coating of the pebbles.
4. Like molten-salt reactors, PBRs are safer than traditional nuclear reactors.
