The neutron-rich nucleus $$^{50}$$Ar is produced by the fragmentation reactions of $$^{54}$$Ca, $$^{55}$$Sc, and $$^{56}$$Ti at the RIBF facility in RIKEN, and its deexcited $$gamma$$ rays are observed for the first time. The first $$2^+$$ level in $$^{50}$$Ar is identified to lie at 1178(18)keV from the most intense $$gamma$$-ray spectra. This experimental data, together with the systematics of the $$2^+$$ levels for surrounding nuclei, is analyzed with large-scale shell-model calculations. Consequently, the $$N=32$$ sub-shell gap in $$^{50}$$Ar is equivalent to that of $$^{52}$$Ca, thus making the $$2^+$$ level in $$^{50}$$Ar higher than that of $$^{48}$$Ar. The shell-model calculation also predicts that the $$N=34$$ sub-shell gap enhances in going from Ca to Ar, which will be verified by forthcoming experiments for $$^{52}$$Ar.

Nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material to provide evidence for nuclear attribution by determining origin, history, transit routes and purpose involving such material. Nuclear forensics activity includes sampling of the illicit material, analysis of the samples and evaluation of the attribution by comparing the analyzed data with database or numerical simulation. Because the nuclear forensics technologies specify the origin of the nuclear materials used illegal dealings or nuclear terrorism, it becomes possible to identify and indict offenders, hence to enhance deterrent effect against such terrorism. Worldwide network on nuclear forensics can contribute to strengthen global nuclear security regime. In this paper, the results of research and development of fundamental nuclear forensics technologies performed in Japan Atomic Energy Agency during the fiscal term of 2011-2013 were reported.

International forum on peaceful use of nuclear energy and nuclear non-proliferation was held at Gakushi-kaikan, Tokyo on February 2-3, 2011 in cooperation with The Japan Institute of International Affairs (JIIA) and The University of Tokyo Global COE. In our International Forum, we would like to encourage active discussion of international challenges to and solutions for compatibility between peaceful use of nuclear energy and nuclear non-proliferation, and international cooperation for emerging nuclear energy states. It was successfully carried out with as many as 310 participants and a lot of discussions. This report includes abstracts of keynote speeches, summary of panel discussions and materials of the presentations in the forum.

The assembly technique to the capsular irradiation rig newly developed was established. In the irradiation examination, the assembling disassembling and reassembling to PFB110 "B11(1), B11(2)" and PFB140 "B14" that built in Am-MOX fuel pin was achieved. The reassembly technique by recycling the irradiation material was established in the assembly of B11(2). This time, the assembly and disassembly of B11 (1) were reported. Moreover, the assembly of B14 which improved the assembly technology of B11 (1) was reported.

We have succeeded in measuring microscopic magnetic hysteresis loop of amorphous Tb$$_{43}$$Co$$_{57}$$ film. Spin selective magnetic hysteresis (SSMH) loop was measured by magnetic Compton scattering at synchrotron radiation facility SPring-8 and obtaining orbital selective magnetic hysteresis (OSMH) loop was firstly obtained by combining with result of macroscopic magnetic hysteresis loop.

R&D on nuclear forensics technology at JAEA

Sakurai, Satoshi; Watahiki, Masaru; Suzuki, Mitsutoshi; Kuno, Yusuke

Proceedings of INMM 52nd Annual Meeting (CD-ROM), 6 Pages, 2011/07

The national statement made by the Japan Government at 2010 Nuclear Security Summit at Washington D.C., U.S.A. was to develop its nuclear forensics detection and analysis technologies in a three-year period and to share them with the international community to contribute to strengthening the nuclear security regime. The Japan Atomic Energy Agency, JAEA, is the organization that possesses analytical capabilities with the potential to fulfill this nuclear forensics mission, since JAEA has been developing a wide range of analytical techniques for nuclear material samples from large size ones to trace level ones of environmental sampling. For this reason, JAEA starts R&D on nuclear forensics technology from JFY 2011. In the presentation reported will be JAEA's outline of R&D to establish nuclear forensics analytical capabilities including international cooperation. The summary of International Workshop on Nuclear Forensics on 5-6 October 2010 at Tokai, Japan will be also reported.
