WebThe function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. The coolant system plays a pivotal role in performing this function. A coolant fluid enters the core at low temperature and exits at a higher temperature after collecting the fission energy.

WebThe problem was not an ongoing chain reaction, but rather the inability to keep cool the reactors. As a result, water began to evaporate off, which meant even more radioactivity was given off. In short, the control rods weren't the issue. Nuclear power plants have such complex safety structures, and quite right. WebNuclear reactors contain and control nuclear fission, the process where atoms split and release energy. A large fissile atomic nucleus, for example, uranium-235 or plutonium-239, absorbs a neutron causing the heavy nucleus to split into at least two lighter nuclei. This split releases kinetic energy, gamma radiation, and free neutrons.
Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves decaying. These elements have … See more Control rods are inserted into the core of a nuclear reactor and adjusted in order to control the rate of the nuclear chain reaction and, thereby, the thermal power output of the reactor, the rate of steam production, and the See more Chemical elements with usefully high neutron capture cross-sections include silver, indium, and cadmium.
