Transmutation of the actinide neptunium-237 with a hybrid reactor

K.M. Feng, J.H. Huang1995年Fusion Engineering and DesignIF 1.7出版社

AbstractCalculations and analyses on the transmutation of long-lived actinide 237Np radioactive waste with a fusion-fission hybrid reactor are reported. A new waste management concept of burning HLW (high-level waste), utilizing the released energy and converting 237Np into 239Pu fissile fuel through transmutation has been adopted. Time-dependent depletion calculations were performed using a modified version of the BISON 1.5 one-dimensional neutron transport and burn-up calculation code system. The transmutation rate of 237Np and its relationship to neutron wall loading and Pu and Np concentrations in the transmutation zone were explored; relevant results are given.

核融合・核分裂ハイブリッド炉による長寿命アクチニド放射性廃棄物237Npの核変換に関する計算と解析について報告する。高レベル放射性廃棄物(HLW)を燃焼させ、放出されるエネルギーを利用し、核変換によって237Npを核分裂性燃料239Puに転換するという新たな廃棄物管理概念を採用した。時間依存の燃焼計算は、修正版のBISON 1.5一次元中性子輸送・燃焼計算コードシステムを用いて実施した。237Npの核変換率と、中性子壁負荷および核変換領域におけるPuおよびNp濃度との関係を調査し、関連する結果を示す。
