Control rods are used in nuclear power plants to shut down the plant, but nuclear plants cannot go from producing at full power to producing zero
Control rods are used in nuclear power plants to shut down the plant, but nuclear plants cannot go from producing at full power to producing zero power very quickly. Why?
Because control rods can only stop new fission reactions; they cannot stop existing reactions.
Because there aren’t enough control rods in a typical nuclear power plant.
Because reducing power that quickly would cost nuclear plant operators too much money.
Because doing so would cause diesel generators and pumps to fail.
Because doing so would require a release of radiation into the atmosphere.
