Thorium 232 neutrons

WebAug 25, 2024 · The thorium-232 absorbs neutrons from the reactor core to turn into protactinium-233, decaying (27-day half-life) to U-233. Molten salt reactors utilize molten fluoride salts as a primary coolant at low pressure. This item is not a radical derivation while the fuel is solid and fixed. WebUranium-232 (232 U) is an isotope of uranium.It has a half-life of around 69 years and is a side product in the thorium cycle.It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it …
