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.

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. 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 …
WebMar 16, 2011 · This test has been previously described in detail. 10 In brief, this test measures adenosine diphospate−induced platelet agglutination as an increase in light transmittance and uses a proprietary algorithm to report values in P2Y 12 reaction units (PRU). A higher PRU result reflects greater P2Y 12-mediated reactivity. Specialized … WebTests were made of the shutdown element at a temperature of 80° C. to 500° C. and with a one-hour test at 300° C., an average of 1.5 mg of gadolinium was deposited per fuel element ball.
