Acta 2014; 102(6): 489–504 Tashi Parsons-Moss, Harun Tüysüz, Deborah Wang, Stephen Jones, Daniel Olive, and Heino Nitsche* Plutonium sorption to nanocast mesoporous carbon Abstract: Nanocast ordered mesoporous carbons are at- tractive as sorbents because of their extremely high sur- face areas and large pore volumes. This paper compares Pu uptake, added as Pu(VI), to both untreated and chemi- cally oxidized CMK-(carbon molecular sieves from KAIST) type mesoporous carbon with that to a commercial amor- phous activated carbon

Introduction Plutonium dioxide P u O 2 $$\left({{\rm{Pu}}{{\rm{O}}_2}} \right)$$ , generally used in mixed compound (MOX), is an important material as a fuel and a stable storage instrument in nuclear reactors. Our knowledge of this material is limited due to toxicity and radioactivity, which make it difficult to study. The melting temperature of PuO 2 is an important parameter in studying phase diagram of its mixed oxide, generally with UO 2 , at high temperature. There have been a few experiments that aim to determine the melting temperature of PuO 2 [ 1 – 3

Myasoedov On existence and properties of plutonium(VIII) derivatives Abstract: The existence of Pu(VIII) was shown in alkaline solutions and in nonpolar solvents (CCl 4 and CHCl 3 ) on the ground of such experimental facts like extraction of plutonium species, obtained by means of ozonization of Pu(VI) alkaline solutions into CCl 4 and CHCl 3 ; volatility of Pu compounds out of aqueous alkaline solutions, and
