The partitioning and transmutation (P-T) technology has promising potential for volume reduction and mitigation of degree of harmfulness of high-level radioactive waste. JAEA is developing the P-T technology combined with accelerator driven systems (ADS) [1]. One of critical issues affecting the feasibility of ADS is the proton beam window (PBW) which functions as a boundary between the...

There have been indications on existing sterile neutrinos since 1990's. Those indications are based on the accelerator neutrino (numu >nue) experiments, reactor neutrino (nuebar -> X) experiments and calibrations of solar neutrino experiments (nue->X) The sterile neutrinos do not have weak interactions, therefore the measurements on the sterile neutrinos usually use the neutrino oscillations...

The research reactor JRR-3 submitted an application for a modification of the installation permit to confirm compliance with the new regulatory standards on September 26, 2014, and received the permit on November 7, 2008, after an examination that lasted about four years. Subsequently, over a period of about two years from April 1991, the plant completed seismic reinforcement work, safety...

Accurate data of neutron-capture cross sections of minor actinides (MAs) and long-lived fission products (LLFPs) are important in detailed engineering designs and safety evaluations of innovative nuclear reactor systems. However, accurate measurements are very difficult due to high radioactivity of these samples.

To satisfy these demands, Accurate Neutron-Nucleus Reaction measurement...
