Carbothermic synthesis of (Cm,Pu)N

Thermochemical and thermophysical properties of minor actinide compounds

“…Preparation of actinide nitrides of AmN and (Cm,Pu)N has been reported [8,9] [10][11][12][13][14]. Recently, (Np,Am)N, (Pu,Am)N, (Pu,Am,Cm)N and (Np,Pu,Am,Cm)N were successfully synthesized and analyzed [15].…”

Thermophysical properties of several nitrides prepared by spark plasma sintering

“…However, several problems exist in the fabrication processes. One of the problems is costly-15N extraction [4] and another is the high sintering-resistance of the nitride fuel [5][6][7][8]. Conventionally, long milling process, addition of sintering additive, and high sintering temperature were necessary for fabrication of the high-density nitride pellets.…”

Thermochemical studies of advanced nuclear fuels and materials

“…In the accelerator-driven transmutation system, the fuel would consist of actinide nitrides dispersed or dissolved in a neutronically inert matrix. The mutual miscibility among the actinide mononitrides has been demonstrated recently in the fabrication of (Cm, Pu)N by Takano et al [14]. The (Cm 0.4 Pu 0.6 )O 2 was successfully converted to the mixed mononitrides by the carbothermic synthesis in a gas stream of nitrogen and hydrogen.…”
