The disposal of radioactive waste from the research facility need to calculate from the radioactivity concentration that based on variously nuclear fuels and materials. In Japan Atomic Energy Agency Oarai Research and Development Institute, the study on considering disposal is being advanced among the facilities which generate radioactive waste as well as the facilities which process radioactive waste. This report summarizes a study result in FY2020 about the evaluation method to determine the radioactivity concentration in radioactive waste on Oarai Research and Development Institute.

Times Cited Count：11 Percentile：46.11(Materials Science, Multidisciplinary)The thermal expansion and crystal structure of A-type carbonate apatite with the monoclinic symmetry was investigated using the neutron powder diffraction at room temperature, 200, 300, 400 and 500
C. The 
-axis and 
-axis lattice parameters were 0.9568 and 0.6868 nm at room temperature, and those were linearly increased with the increase of temperature. It was found that the linear thermal expansion coefficient of -axis was 1.31

Hydroxyapatite is the main inorganic component of bone and tooth minerals, in which CO
ions partially substitute for OH and/or PO
ions. In this study, high purity type A carbonate apatite, Ca
(PO)
(CO)
powder completely substituted by carbonate ions were synthesized by a treatment of low crystalline hydroxyapatite powder, Ca(PO)(OH)
) in a dry CO
flow at 1000 C. The crystal structure of the sample was the monoclinic symmetry with space group of 
and the lattice parameters, = 0.9566 (1), 
= 1.9063 (2), = 0.6867 (1) nm and 
=119.84 (1), which was refined by a Rietveld method with neutron diffraction data.

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.
