A dollar is a unit of reactivity for a nuclear reactor, calibrated to the interval between the conditions of delayed criticality and prompt criticality. Zero dollars is defined to be the threshold of slow criticality, which means a steady reaction rate. One dollar is defined to be the threshold of prompt criticality, which means a nuclear excursion or explosion. A cent is 1⁄100 of a dollar. WebMar 10, 2013 · What’s a motivation-reaction unit?

WebSep 16, 2024 · For a chemical reaction, the enthalpy of reaction ( ΔHrxn) is the difference in enthalpy between products and reactants; the units of ΔHrxn are kilojoules per mole. Reversing a chemical reaction reverses the sign of ΔHrxn. Contributors and Attributions Modified by Joshua Halpern ( Howard University) In nuclear reactor engineering, a per cent mille is equal to one-thousandth of a percent of the reactivity, denoted by Greek lowercase letter rho. Reactivity is a dimensionless unit representing a departure from criticality, calculated by: where keff denotes the effective multiplication factor for the reaction. Therefore, one pcm is equal to:

WebJan 1, 2010 · Reactivity is the measure of the departure of a reactor from critical. The effective multiplication factor, k eff, determines whether the neutron density within a reactor will remain constant or change.Since the power level is directly proportional to the neutron density, whenever k eff = 1.0, the reactor is critical and operates at a constant power level.
