ydinenergiajärjestelmä
Ydinenergiajärjestelmä refers to a system that utilizes nuclear reactions to generate energy, typically in the form of electricity. The core component of such a system is a nuclear reactor, where controlled nuclear fission or fusion reactions take place. In fission reactors, heavy atomic nuclei, such as uranium or plutonium, are split into lighter nuclei, releasing a significant amount of energy. This energy heats a working fluid, usually water, which then drives a turbine connected to a generator to produce electricity. Fusion reactors, on the other hand, aim to combine light atomic nuclei, like isotopes of hydrogen, to release energy. This technology is still in its developmental stages.
The safe operation of a ydinenergiajärjestelmä requires robust containment structures to prevent the release of radioactive
