## Void Coefficient - Nuclear Power

2019-2-26 · Boiling water reactors generally have negative void coefficients, and during normal operation the negative void coefficient allows reactor power to be adjusted by changing the rate of water flow through the core. The negative void coefficient acts against power increase and contribute to the reactor stability. As the reactor power is raised to

## Nuclear chain reaction - Wikipedia

2019-2-18 · A nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, Every fission causes an average of one more fission, leading to a fission (and power) level that is constant. Nuclear power plants operate with k = 1 unless the power level is being increased or decreased.
