tuumareaktoris

Tuumareaktoris is a term that can refer to a nuclear reactor, particularly in the Finnish language. A nuclear reactor is a device that initiates and controls a sustained nuclear chain reaction. The primary purpose of most nuclear reactors in the world is to generate electricity. This is achieved by using the heat produced from the nuclear fission process to produce steam, which then drives a turbine connected to a generator.

The core of a nuclear reactor contains nuclear fuel, typically uranium or plutonium, which undergoes fission when bombarded with neutrons. This fission process releases a large amount of energy in the form of heat and more neutrons, which can then go on to cause further fission events, creating a chain reaction. Control rods, made of neutron-absorbing materials, are used to regulate the rate of the chain reaction by absorbing excess neutrons. A coolant, such as water or gas, circulates through the reactor core to remove the heat generated. This heat is then transferred to another fluid to produce steam.

Nuclear reactors are also used for other purposes, including research, medical isotope production, and propulsion for submarines and aircraft carriers. The design and operation of nuclear reactors are subject to strict safety regulations due to the potential hazards associated with radioactive materials and the chain reaction.
