Simplified mass ablation and relocation treatment for pellet injection optimization

Polevoi, A. R.*; Shimada, Michiya

Plasma Physics and Controlled Fusion, 43(11), p.1525 - 1533, 2001/11

A simplified mass ablation and relocation treatment of high field side/low field side pellet injection is proposed. It includes a model of pellet ablation, parallel flow model for the attached ablation channel and a simplified magnetohydrodynamic (MHD) pellet displacement model. This treatment reveals satisfactory agreement with the present day experiments on ASDEX-U and DIII-D tokamaks. The model provides the optimisation directions for deep plasma fuelling in experiments. Calculation with ITER parameters suggests that deep penetration up to ~ 60-70% of minor radius is possible at modest velocity <0.5 km/s with high field side injection.

R&D on nitride fuel cycle for MA transmutation to enhance safety and economy, 4; Correlation of milling condition and sintered density of nitride fuel surrogate material

Takaki, Seiya; Takano, Masahide

no journal, , 

Regarding nitride fuel for nuclear transformation of minor actinides, in order to obtain fundamental knowledge for sintering density control by adding pore former, under the various grinding conditions, Dy$$_{0.3}$$Zr$$_{0.7}$$N simulated nitride fuel Sintering experiments were carried out. Although the sintered density of the simulated nitride fuel increases with the increase of the specific surface area of the pulverized powder, it can be confirmed that the sintered density decreases as the strain in the grain increases.
