The neutron capture cross section of light elements, such as Li, Be, and B, plays an important role in inhomogeneous Big-Bang nucleosynthesis scenarios or in explosive nucleosynthesis, like r-process. However, data for neutron capture reaction of light elements sparse and / or disagree in the astrophysical relevant energy region, since the cross section of light elements is quite small even at the thermal energy. Intense pulsed neutron beam provided by the Material and Life science experimental Facility (MLF) in J-PARC and high performance Ge spectrometer, which is the main detector of the Accurate Neutron-Nucleus Reaction Measurement Instrument (ANNRI) installed at Beam Line No. 04 of MLF in the J-PARC, will allow us to study neutron capture reaction of light elements. At first we have measured the neutron capture cross section of Li-7 at the MLF in the J-PARC. In this contribution, we will present the results of the measurement.

A novel removal technique with ultra-fine bubbles has been proposed for decommissioning of nuclear facilities. The performance of removal technology with ultra-fine bubbles was evaluated in cold experiments with simulated contaminants precipitated Co oxides and hot experiments with radioactive contaminants.

【課題】化合物膜を溶解させずに、微細な部位の化合物膜を安定的に除去可能な化合物膜の剥離除去方法を提供する。 【解決手段】材料P1表面上の化合物膜を剥離して除去する化合物膜の剥離除去方法において、材料P1表面にナノバブル液Uを接触させた状態で、ナノバブル液Uに超音波を照射して、化合物膜を除去する。これにより、化合物膜を溶解する試薬を利用することなく、材料P1表面からの化合物膜の安定的な除去が可能である。また、ナノバブル液Uは材料P1の細かな部位にも進入することから、微細な部位の化合物膜を確実に除去することができる。
