WebJan 23, 2024 · In an addition reaction the number of σ-bonds in the substrate molecule increases, usually at the expense of one or more π-bonds. The reverse is true of elimination reactions, i.e.the number of σ-bonds in the substrate decreases, and new π-bonds are often formed.Substitution reactions, as the name implies, are characterized by replacement of … WebThe fuel temperature coefficient – FTC or DTC is defined as the change in reactivity per degree change in the fuel temperature.. α f = dρ ⁄ dT f. It is expressed in units of pcm/°C or pcm/°F. The magnitude and sign (+ or -) of the fuel temperature coefficient is primarily a function of the fuel composition, especially the fuel enrichment.In power reactors, in …

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. 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 …
