Reactor reactivity
WebJan 24, 2024 · In practice, reactivity is far less than 1 and is quantified in per cent mille [hundred-thousandths] (1 pcm = 10 −5 [−]).Use of the criterion expressing k eff in relation to 1 appears an extremely mathematical approach, and one might well wonder how an actual reactor may be built such that its k eff is exactly equal to 1. Nevertheless, as we will see, …
