Web(The term inhour comes from expressing reactivity in the units of inverse hours. The inhour unit is then that reactivity which will make the stable reactor period equal to one hour.) These are numerous different formulations of the reactivity equation, but this one will suffice for the purposes of this manual. ... 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.
