Reaktorigas

Reaktorgas is a term used to describe the mixture of gases produced during the operation of a nuclear reactor. The composition of reaktorgas varies depending on the type of reactor, its fuel, and operating conditions, but it generally includes fission products, activation products, and gases from the coolant or moderator. Fission products are the direct result of the nuclear fission process, where heavy atomic nuclei split into lighter ones, releasing energy and various isotopes. Some of these isotopes are radioactive gases, such as xenon and krypton. Activation products are formed when neutrons from the fission process interact with the reactor materials, such as the fuel cladding or structural components, creating radioactive isotopes. In water-cooled reactors, gases like hydrogen and oxygen can be produced through radiolysis of water, the decomposition of water by radiation. In gas-cooled reactors, the coolant gas itself can become activated. The release and containment of reaktorgas are critical safety considerations in nuclear power plant design and operation. Systems are in place to filter, process, and monitor these gases to prevent their release into the environment. The management of reaktorgas is a key aspect of nuclear waste management and radiation protection.
