Reactivity units
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: WebMar 10, 2013 · What’s a motivation-reaction unit? Dwight V.
