Qu'est-ce que le thorium - Connaissance des Énergies

Le thorium est un métal très lourd de couleur argentée. Il est abondant dans la croûte terrestre où il est présent sous la forme d'un seul isotope, le thorium 232 (1).Le thorium se situe en fin du tableau de Mendeleïev (Z = 90) dans la famille des actinides, tout comme l'uranium naturel (Z = 92) (2).. Le thorium a été identifié vers 1830 en Norvège.

Greia med thorium | Titan.uio.no

Thorium-brenselssyklusen trenger ett nøytron for å omdanne thorium-232 til uran-233 og ett nøytron for å fisjonere (spalte) uran-233, for hver eneste nøytron-generasjon. Siden Eta og Alpha (som det sto om i del 4 av denne føljetongen) er det de er, er det i prinsippet mulig å breede i et termisk nøytronspektrum (altså med nøytroner med lav energi).
