WebReactor Dynamics In this paper, the term reactor dynamics refers to changes in reactivity or any of the kinetics parameters that occur on timescales on the order of hours to years. The primary source of these sorts of changes is fuel burnup. Webfour safe shutdown functions (reactor reactivity control, reactor coolant pressure control, reactor coolant inventory control, and decay heat removal) are described in detail for PWRs in this section. A.2.1 Reactor Reactivity Control (PWR) The safe shutdown alternatives for accomplishing the reactor reactivity control function for
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).
