Thorium As Nuclear Fuel: the good and the bad. Thorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce highquality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process.

Radkowsky Thorium Fuel: Voordelen op zowel economisch

Thorium, alternatieve kernenergie, minder vervuilend en goedkoperNaar aanleiding van de kernramp in Fukushima werd nogmaals bewezen dat het gebruik van kernenergie een mogelijk gevaar voor de samenleving vormt. Dat wil niet zeggen dat het in een slecht daglicht moet worden gesteld. Nucleaire energie is veel minder vervuilend dan energie opgewekt door middel van gas- of koolcentrales.

Tous les isotopes du thorium sont radioactifs. Le thorium naturel est constitué presque exclusivement du thorium 232, de très longue demi-vie (14 milliards d'années). En raison de l'abondance significative du thorium 230 (fraction molaire de l'ordre de 2,2 × 10 −4), le thorium n'est cependant pas un élément mononucléidique [12]..
