In the Analyzed Liquid Treatment Facility of Japan Nuclear Fuel Co., Ltd. (JNFL) MOX Fuel Fabrication Plant (J-MOX), the interfere by salts with the analysis of gross alpha activity concentration analysis will be caused during the treatment process. Therefore, JNFL devised the desalting method using a solid-phase extraction chromatography. Japan Atomic Energy Agency carried out the experimental study to confirm the validity of this desalting method for the treatment liquid based on the contract with JNFL. This study consists of three experiments as follows: Step 1 - Selection of an optical solid-phase extraction agent, Step 2 - Evaluation of variation optical solid-phase extraction agent, and Step 3 - Application of the imitation liquid waste. The result of Step 1 determined the solid-phase extraction agent (InertSep ME-2) and the optimum condition (aspiration method by manifold (about 5-10 mL/min), 3M nitric acid as eluent, pH: 5, and no adjustment of ionic valence). Then, the result of Step 2 and 3 made sure the validation of this method by obtaining over 70% recovery for the imitation liquid waste sample of the Analyzed Liquid Treatment Facility of J-MOX.

Times Cited Count：15 Percentile：35.15(Biochemistry & Molecular Biology)A new method was developed to allow direct visualization of damaged sites on individual DNA molecules. Fluorescence in situ hybridization (FISH) on extended DNA molecules was modified to detect a single abasic site. Abasic sites were specifically labeled with a biotinylated aldehyde-reactive-probe (ARP) and fluorochrome-conjugated streptavidin. The light emitted by a single fluorochrome-DNA complex was calibrated. The number of abasic sites on the DNA molecule was estimated by counting each fluorochrome-DNA complex. The present study directly visualized and characterized the abasic sites of single DNA molecules.

This report describes the operational experience during the MK-II core and a theme of the future Fuel Cleaning Facility in "JOYO". Following results are obtained. (1)The sodium guantity adhered the spent core elements is influenced by the inner structure of the elements. (2)The corrosion product guantity in the washing waste water is mainly influenced by the corrosion product adhering to material surface. (3)The sodium guantity in the water which is contained in a can differs from the kind of elements. (Maximum value of sodium is about 8 grams) (4)During the washing by demineralized water, reaction velocity and guantity of sodium which adheres to a element differ from the kind of elements. Therefore, it is necessary to establish the washing way depend on the elements.
