kärnreaktiva
Kärnreaktiva is a Swedish term that translates to "nuclear-reactive" in English. It is most commonly used in the context of nuclear power and nuclear technology. The term describes a substance or material that can undergo or participate in a nuclear reaction. This includes fissile materials, such as uranium-235 or plutonium-239, which can sustain a chain reaction when bombarded with neutrons, releasing significant amounts of energy. It can also refer to materials that are capable of absorbing neutrons, or those that are designed to withstand the extreme conditions within a nuclear reactor core.
In a broader sense, kärnreaktiva can also be applied to the entire system of a nuclear reactor,
