WebPlatelet reactivity was measured as P2Y 12 reaction unit (PRU) values using the VerifyNow system (Instrumentation Laboratory) and results were reported in PRU. The measurement … 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. ...
WebSep 19, 2024 · The units are thus moles per liter per unit time, written as M/s, M/min, or M/h. To measure reaction rates, chemists initiate the reaction, measure the concentration of the reactant or product at different times as the reaction progresses, perhaps plot the concentration as a function of time on a graph, and then calculate the change in the ... WebApr 6, 2007 · In the United States, mid-20ᵗʰ century – present, a unit of reactivity used in nuclear engineering. One inhour is the reactivity of a critical reactor in which neutron flux increases (positive value) or decreases (negative value) by a factor of e in 1 hour. It is sometimes said that the reactivity in inhours is equal to the reciprocal of ...
WebMathematically, reactivity is a dimensionless number, but various units can express it. The most common units for research reactors are units normalized to the delayed neutron fraction (e.g.,, cents and dollars) because they exactly express a departure from prompt criticality conditions. 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.
