We have demonstrated efficient second harmonic generation (SHG) of high energy fundamental Nd:YAG laser pulse energy of the multi-joule (J) level at 10-Hz using high optical quality top-seeded solution growth CsBO (TSSG-CBO) crystal. SHG output energy of 1.2 J is obtained with a conversion efficiency of 60%. These results indicate that CBO is a good candidate material for high energy SHG of Nd-doped lasers at the several J level or more with high repetition rate.

The Advanced Volume Reduction Facilities (AVRF) is constructed to manufacture the waste packages of radioactive waste for disposal in the Nuclear Science Research Institute of the Japan Atomic Energy Agency. The AVRF is constituted from two facilities. The one is the Waste Size Reduction and Storage Facility (WSRSF) which is for reducing waste size, sorting into each material and storing the waste package. The other is the Waste Volume Reduction Facility (WVRF) which is for manufacturing the waste package by volume reducing treatment and stabilizing treatment. WVRF has an induction melting furnace, a plasma melting furnace, an incinerator, and a super compactor for treatment. In this report, we summarized about the basic concept of constructing AVRF, the constitution of facilities, the specifications of machineries and the state of trial operation until March of 2006.

We reported an IR-induced reduction of locomotory rate of in the absence of food. In the previous experiments, wild-type animals were irradiated with -rays in the whole body, and measured the motility using "body bends" (the number of bends in the anterior body region at 20-s intervals). However, the IR-induced effects in the central and posterior body region were not evaluated by the body bends. In the present study, to investigate the IR-induced effects in more detail, we propose a novel method to evaluate the motility of the whole body using the video-based analysis.

We examined the effects of ionizing radiation (IR) on locomotory behavior using , and reported an IR-induced reduction of locomotory rate in the absence of food. In the previous experiments, wild-type animals were irradiated with -rays in the whole body, and measured the motility using "body bends" (the number of bends in the anterior body region at 20-s intervals). However, the IR-induced effects in the central and posterior body region were not evaluated by the body bends. Therefore, we propose a novel method evaluating the motility of whole body by using the video-based analysis. Animals were irradiated with graded doses of Co -rays. Immediately after irradiation, we video-recorded the animals, and analyzed the trajectories and bends at 17 points of the body. The proposed method provides some novel insight about the IR-induced changes on 's locomotion.
