WebOct 1, 2013 · For the case of subcritical reactors, reactivity monitoring is important during reactor startup, for low-power physical tests and during full-power operation. This is due to the fact that, as the nuclear fuel is burned one has to adjust the proton beam intensity to keep the production of electricity constant during normal operation. WebOct 1, 2013 · Molten salt reactors (MSRs) are liquid-fueled reactors that can be used for burning actinides, producing electricity, producing hydrogen, and producing fissile fuels (breeding). Fissile, fertile, and fission products are dissolved in a high-temperature, molten fluoride salt with a very high boiling temperature (∼1400 °C).
