This document presents the data of geological investigations in the shafts and research galleries from the depth of 300m to 500m of the MIU from the 2008 fiscal year to the 2011 fiscal year. In the shafts and research galleries of the MIU, although the Cretaceous Toki granite is distributed, pegmatite, aplite and lampropyre dike are distributed partially.

A hydrogen combustion experiment was conducted to simulate the sodium-concrete reaction under oxygen-existing conditions. As a result, it was found that hydrogen was burnt at the sodium pool surface because as sodium combustion heat played a role of the ignition energy, and the hydrogen combination ratio increased with the increase of the oxygen concentration in the atmosphere.

This document presents the data of geological investigations in the shafts and research galleries to the depth of 300 m of the MIU from the 2004 fiscal year to the 2008 fiscal year. In the shafts and research galleries of the MIU, the Cretaceous Toki granite is unconformably overlain by the generally flat lying Miocene Mizunami Group (younging upwards from the Toki Lignite-bearing Formation to the Hongo and Akeyo Formations) with a depth of about 166 m to 168 m.

We investigate one of these innovative water reactors; Fast Spectrum Light Water Reactor (FLWR). It has unique construction for the reactor core but the fuel cladding material will be exposed in high internal pressure and axial load and complex temperature distribution. Therefore, we conducted a specially designed fatigue-creep test that were simulated several parameters (thermal distribution, temperature variation, internal pressure variation and binding stress) to evaluate an applicability of fuel cladding material for FLWR. Zircalloy-2, which is common cladding material, was used for the test. Test result was confirmed to compare the deformation value between tested and calculated. The result showed the evaluation method could be controlled several parameters simultaneously and the deformation value after the test coincided to the calculated value. This method is sufficient to evaluate thermal deformation characteristics for FLWR.

J-PARC is a large scale facility of the proton accelerators for the multi-purpose of scientific researches in Japan. This facility consists of three accelerators and three experimental stations. Now, J-PARC is under construction, and LINAC is operated for one year, 3GeV synchrotron has just started the commissioning in this October the 1st. The completion of this facility will be next summer. The control system of accelerators established fundamental performance for the initial commissioning. The most important requirement to the control system of this facility is to minimize the activation of accelerator devices. In this paper, we show that the performances of each layer of this control system have been achieved in the initial stage.

We conducted a validation calculation in order to mainly confirm alumina-related reactions considered in the sodium-concrete reaction model in the CONTAIN/LMR code. As a result, it was found that though there were some problems in quantitative evaluation, CONTAIN/LMR could simulate the characteristics of these reactions.

We started a project on "Development of Estimation Technology for Availability of Measure for Failure of Containment Vessel in Sodium Cooled Fast Reactor" as a program for R&D for nuclear system, development of basic technology for safety. We planed to develop an evaluation method based on experiments of hydrogen generation and concrete ablation in sodium-concrete reaction. This report shows the plan and a part of the sodium test.
