Times Cited Count：34 Percentile：91.73(Nuclear Science & Technology)The inorganic-based hydrophobic Pt-catalyst named H1P has been developed especially for efficient oxidation of a tracer level of tritium in the ambient temperature range even in the presence of saturated water vapor. The overall reaction rate constant for H1P catalyst in the ambient temperature range was considerably larger than that for traditionally applied Pt/Al
O
catalyst. Moreover, the decrease in reaction rate for H1P in the presence of saturated water vapor compared with in the absence of water vapor was slight due to its excellence in hydrophobic performance. Oxidation reaction on the catalyst surface is the rate-controlling step in the ambient temperature range and diffusion in a catalyst substratum above 313 K due to its fine porosity. The overall reaction rate constant in the ambient temperature range was dependent on the space velocity and hydrogen concentration in carrier.

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.

The inorganic-based hydrophobic Pt-catalyst named H1P has been developed especially for efficient oxidation of a tracer level of tritium at room temperature even in the presence of saturated water vapor. Overall reaction rate constant of tritium oxidation on a H1P catalyst in a flow-through system were determined as a function of space velocity, hydrogen concentration in carrier, temperature of catalyst, water vapor concentration in carrier. The overall reaction rate constant for H1P catalyst at room temperature was considerably larger than that for traditionally applied Pt-alumina catalyst. The overall reaction rate constant at room temperature was dependent on the space velocity and hydrogen concentration in carrier. The overall reaction rate constant under the dry and wet conditions was proportional to hydrogen concentration in carrier to the power 0.33 and 0.44, respectively.

Our group has experience to carry out the experiment with small electrochemical devices at heavy-water-moderated Advanced Thermal Reactor (ATR, FUGEN), and observed a clear signal increase near the reactor core. The present study is aiming at demonstrating the response of the electrochemical device to tritium amount. The experiments were performed at (1) Pressurized right Water Reactor (PWR, tritium amount of 30 g and a great quantity of beta emitters) at a distance of 26 m from the core, and (2) Tritium Process Laboratory of Japan Atomic Energy Agency (TPL, tritium amount ~10 g) at a position of 8.6 m from the source. Signal increase was observed in both measurements. Analysis made clear that the detector signal is ascribed to the amount of low-energy beta emitters of plutonium 241 and tritium in the PWR experiment while it is attributed to the quantity of tritium in the TPL measurement.

The water glass type neutron absorber has been developed as a measure to precaution of re-criticality during fuel debris retrieval from nuclear reactor, etc. Since the surface of the fuel debris is covered with the neutron absorber, the coating of the neutron absorber was suggested to inhibit the evaporation of water in the debris during the drying process of fuel debris. The drying test using the mock test piece was carried out in order to evaluate the effect on the drying behavior when the surface of the fuel debris is covered with the neutron absorber. The outline and basic study of the drying test will be reported in this presentation.

In order to study the astrophysical origin of a rare isotope Sn, a neutron capture cross-section for the 
Cd(n,)Cd
reaction has been measured with neutrons provided from a nuclear reactor. The cross-section ratio of the isomer to the ground state has been calculated as a function of the incident neutron energy, E, by using a statistical model. The calculated ratios are almost constant over a wide range of E 
100 keV. We have evaluated the 
-process contribution to the solar abundance of Sn using the classical steady-flow model.
