アクチナイド核種の高精度・高信頼度核データは核変換システムの核設計,安全性と性能評価のために必要である。特に、Np, Pu, Am核種の中性子捕獲断面積は核廃棄物の核変換処理方針の策定と最適化のために重要である。2004年のn_TOF実験において新しい実験手法を用いて得られたこれらの高精度核データについて報告する。

Accurate and reliable neutron cross section data for actinides are necessary for the proper design, safety reguartion and precise performance assessment of transmutaion devices. In particular, the neutron capture cross sections of Np, Pu and Am play a key role in the design and optimization of a strategy for the Nuclear Waste Transmutation. The listed cross sections have been measured in 2004 at n_TOF with a high accuracy due to a combination of features unique in the world.
