Fabrication development of high-density MoO$$_{3}$$ pellets for (n, $$gamma$$) $$^{99}$$Mo production

Nishikata, Kaori; Kimura, Akihiro; Tsuchiya, Kunihiko; Suzuki, Kunihiko*; Akiyama, Hiroaki*; Nagakura, Masaaki*; Kawauchi, Yukimasa*; Tanase, Masakazu*

Proceedings of 5th International Symposium on Material Testing Reactors (ISMTR-5) (Internet), 9 Pages, 2012/10

In this study, experimental fabrication tests of the high-density MoO$$_{3}$$ pellets were carried out by the Plasma Activated Sintering (PAS) method, which requires relatively lower temperature and shorter time to fabricate the pellets. From the results, the PAS method combined with oxidation process, prior to dissolution into sodium hydroxide solution, is a useful measure to fabricate high-density MoO$$_{3}$$ Pellets for the future domestic production of $$^{rm 99m}$$Tc. The irradiation tests and characterization with these pellets will be carried out under the international cooperation.

The H-Invitational Database (H-InvDB); A Comprehensive annotation resource for human genes and transcripts

Yamasaki, Chisato*; Murakami, Katsuhiko*; Fujii, Yasuyuki*; Sato, Yoshiharu*; Harada, Erimi*; Takeda, Junichi*; Taniya, Takayuki*; Sakate, Ryuichi*; Kikugawa, Shingo*; Shimada, Makoto*; et al.

 Times Cited Count:51 Percentile:71.25(Biochemistry & Molecular Biology)

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.

Imaging technology for internal structure of the nuclear reactor using cosmic ray muons

no journal, , 

Cosmic ray muons can pass through large structures such as industrial plants and buildings including foundation. Engineering Advancement Association of Japan (ENAA) and Kawasaki Geological Engineering (KGE) have developed an exploration system using cosmic ray muons for detecting underground cavities which have a potential to bring about disasters. Japan Atomic Energy Agency (JAEA) has started an applicability test of this technology to the Fukushima Dai-ichi Nuclear Power Plants together with ENAA and KGE in October, 2012. In the test, core internal structures of the High Temperature Engineering Test Reactor (HTTR) will be visualized to obtain practical data on resolution and measuring time necessary for improving the system.
