Japan Atomic Energy Agency (hereinafter referred to as JAEA) has been conducted a geoscientific research and development project at the Mizunami Underground Research Laboratory and the Horonobe Underground Research Laboratory in order to construct scientific and technological basis for geological disposal. As a collaborative research between JAEA and Tokyo Sokki Kenkyujo Co., Ltd. (hereinafter referred to as TML), we focused on the fiber-optic crack detection sensor developed by TML as a method to detect cracks in the support system that may affect the stability of rock cavern during the operation. To verify long-term safety performance of the sensor for decades, "Evaluation test of long-term durability of fiber-optic crack detection sensor and the support system" at the Mizunami Underground Research Laboratory and "Performance evaluation test of fiber-optic crack detection sensor for in-situ crack detection" at the Horonobe Underground Laboratory Research Laboratory were conducted. As the result, we understand that fiber-optic crack detection sensor is applicable measurement method to promptly detect the cracks in the support system.

The condition of facilities and machinery used continuously were investigated before the renewal work of JMTR on FY 2007. The subjects of investigation were reactor building, primary cooling system tanks, secondary cooling system piping and tower, emergency generator and so on. As the result, it was confirmed that some facilities and machinery were necessary to repair and others were used continuously for long term by maintaining on the long-term maintenance plan. JMTR is planed to renew by the result of this investigation.

Koike, Masato; Imazono, Takashi; Kawazoe, Tadashi*; Otsu, Motoichi*; Sano, Kazuo*

A Mo/SiO$$_{2}$$ multilayer laminar-type holographic grating having an average groove density of 2400 lines/mm is designed and fabricated for use with a soft X-ray flat field spectrograph. A varied-line-spaced grooves pattern is generated by the use of an aspheric wavefront recording system and laminar-type grooves are formed by a reactive ion-etching method. The measured first-order diffraction efficiency is 18$$sim$$20%. The flat field spectrograph equipped with the grating indicates a spectral line width of 8$$sim$$14 eV for the emission spectra generated from electron-impact X-ray sources. A Mo/SiO$$_{2}$$ multilayer grating having a groove density of 7600 lines/mm fabricated by use of a new lithography machine based on optical near field technologies showed first-order diffraction efficiency of $$sim$$3%. It is over one order magnitude higher than that of the other orders.

Here we report the new features and improvements in our latest release of the H-Invitational Database, a comprehensive annotation resource for human genes and transcripts. H-InvDB, originally developed as an integrated database of the human transcriptome based on extensive annotation of large sets of fulllength cDNA (FLcDNA) clones, now provides annotation for 120 558 human mRNAs extracted from the International Nucleotide Sequence Databases (INSD), in addition to 54 978 human FLcDNAs, in the latest release H-InvDB. We mapped those human transcripts onto the human genome sequences (NCBI build 36.1) and determined 34 699 human gene clusters, which could define 34 057 protein-coding and 642 non-protein-coding loci; 858 transcribed loci overlapped with predicted pseudogenes.

Responses of two lines of feline T lymphocytes, FeT-J and FL-4, to ionizing radiation were examined in the present study. FL-4 cells, but not FeT-J, were persistently infected with feline immunodeficiency virus. Cells were irradiated with $$^{60}$$Co-$$gamma$$ rays at 2 Gy/min. Surviving fractions were evaluated with clonogenic assay. Apoptosis was detected using TdT-mediated dUTP-biotin nick end labeling (TUNEL) method. Changes in nuclear morphology of viable cells were evaluated by double staining with Hoechst 33342 and ethidium bromide. Mean surviving fractions of FL-4 cells were slightly higher than FeT-J for each radiation dose given. However, dose required to reduce to 63 % of surviving fraction was 1.9 Gy in both cell lines. TUNEL assay, however, revealed the maximum frequency of apoptosis in FL-4 cells ($$<$$20 %) was lower than in FeT-J cells ($$>$$40 %). The time of frequency peak of TUNEL-positive cells in FL-4 was shorter than that of FeT-J. FL-4 cells reached peak level within 24 hours after irradiation, but FeT-J cells needed later than 48 hours after irradiation. Exposure of FL-4 cells to $$gamma$$ rays resulted in the giant- and the multi- nucleus formation. Nuclear swelling occurred to less extent in FeT-J than FL-4 cells. In conclusion, we found the difference in cellular responses to radiation in two lines of feline T lymphocytes. Modes of cell death of FL-4 cells were non-apoptotic and more research would discover new mechanism associated with apoptosis.

Multilayer gratings having a groove density of 7600 lines/mm have been fabricated by depositing Mo/SiO$$_{2}$$ multilayer coating on the surface of laminar-type master gratings fabricated by use of a new lithography machine based on optical near field technologies. The diffraction efficiency was measured by reflectometers in the wavelength range of 0.7-2.0 nm at a synchrotron radiation facility. The multilayer grating having a groove depth of 3nm and multilayer period length of 5.33 nm showed diffraction efficiencies of 0.028 at 0.70 nm and 0.005 at 2.0 nm were observed for the incidence angles of 88.020 deg and 80.764 deg, respectively. We also discuss the analysis of the roughness in terms of Debye-Waller factor comparing the experimental and theoretical diffraction efficiencies as well as the groove depth using experimental efficiency minima of the zero-th order light.
