Third phase formation in the extraction of Pu(IV) nitrate by 30% tri-n-butyl phosphate (TBP) dissolved in n-dodecane or in the highly branched diluent hydrogenated polypropylene tetramer (HPT), which may also be known as 4,4 dipropyl Received 22 June 2005, Accepted 31 October 2005 The views expressed are solely those of the authors and no official support or endorsement of this publication by t...

The present status of neutron beam production techniques above 20 MeV is discussed. Presently, two main methods are used; white beams and quasi-monoenergetic beams. The performances of these two techniques are discussed, as well as the use of such facilities for measurements of nuclear data for fundamental and applied research. Recently, two novel ideas on how to produce extremely intense neutr...

Since the nuclear accident at Fukushima Daiichi Nuclear Power Station in 2011, a considerable number of studies have been conducted to develop tolerant fuel (ATF) claddings for safety enhancement light water reactors. Among many potential ATF claddings, silicon carbide is one most promising candidates with superior features suitable applications. In spite benefits SiC cladding, there are some c...

Overview A new era has dawned for nuclear structure and reaction theory. Renewed interest in the physics of nuclei is fueled by experiments at rare isotope beam facilities, which explore new regions of exotic nuclei; by astrophysical observations and simulations, which require controlled extrapolations of the nuclear equation of state; by the use of nuclei in experiments on fundamental symmetri...

The direct interaction of nuclei with superintense laser fields is studied. We show that present and upcoming high-frequency laser facilities, especially together with a moderate acceleration of the target nuclei to match photon and transition frequency, do allow for resonant laser-nucleus interaction. These direct interactions may be utilized for the model-independent optical measurement of nu...

The Japanese Society of Nuclear Cardiology(JSNC)has given Technical Award for outstanding technologists since 2012 to promote nuclear cardiology research. Yasuyuki Takahashi won the 3rd JSNC Technical Award. This issue of Annals of Nuclear Cardiology contains his review article related to his work wining the prize. Masao Miyagawa, his colleague, also presented another review article concerning ...

As nuclear facilities are introducing digital systems, the cyber security becomes an emerging topic to be analyzed and resolved. The domestic and other nation's regulatory bodies notice this topic and are preparing an appropriate guidance. The nuclear industry where new construction or upgrade of I&C systems is planned is analyzing and establishing a cyber security. A risk-based analysis for th...

The shell-model Monte Carlo (SMMC) technique transforms the traditional nuclear shell-model problem into a path-integral over auxiliary fields. We describe below the method and its applications to four physics issues: calculations of sd-pf-shell nuclei, a discussion of electron-capture rates in pf-shell nuclei, exploration of pairing correlations in unstable nuclei, and level densities in rare ...

An R&D program devoted to new experimental concepts of identification in Atomic (Z) and Mass (A) numbers of light and heavy isotopes produced in nuclear reactions is the goal of the present R&D of the International FAZIA Collaboration (a full list of the members is given at the of this document). The aim is to build prototypes for a new detection array for coming European Radioactive Nuclear Be...
