Fissioituviin

Fissioituviin is a Finnish inflected form derived from the adjective fissioituva, which relates to undergoing nuclear fission. Grammatically, fissioituviin is the illative plural form, used to indicate movement or direction "into" or "to" multiple entities described as fissioituva. Morphologically it combines the root fissio (fission) with the verbal-adjective suffix -ituva (becoming or capable of undergoing) and the illative plural ending -iin.

In scientific and technical contexts the base adjective fissioituva describes materials or isotopes that undergo or are capable of undergoing fission. Depending on usage, it may correspond to English terms such as "fissionable" or "fissile," with precise meaning determined by context (for example whether thermal-neutron-induced fission is implied). The inflected form fissioituviin appears in phrases that specify movement, transfer or reference to groups of such materials, for example: "siirtyminen fissioituviin isotooppeihin" (transition to fissionable isotopes).

The term is primarily found in Finnish-language texts on nuclear physics, reactor engineering and related policy or technical documentation. Its usage is specialized and typically limited to contexts discussing nuclear reactions, fuel cycles and isotopic behavior.
