被引用回数：58 パーセンタイル：99.18(Nuclear Science & Technology)SFCOMPO-2.0 is the new release of the NEA database of experimentally measured assays, i.e. isotopic concentrations from destructive radiochemical analyses of spent nuclear fuel samples, complemented with design information of the fuel assembly and fuel rod from which each sample was taken, as well as with relevant information on operating conditions and characteristics of the host reactors, which are necessary for the modelling and simulation of the isotopic evolution of the fuel during irradiation. SFCOMPO-2.0 has been developed and is maintained by the OECD Nuclear Energy Agency (NEA) under the guidance of the Expert Group on Assay Data of Spent Nuclear Fuel (EGADSNF) of the NEA Working Party on Nuclear Criticality Safety (WPNCS). In this paper, the new database is described. Applications of SFCOMPO-2.0 for computer code validation, integral nuclear data benchmarking, and uncertainty analysis in nuclear waste package analysis are briefly illustrated.

被引用回数：13 パーセンタイル：46.71(Polymer Science)We investigated the structure and the swelling behavior of two synthesized hydrocarbon polymer electrolyte membranes, made of multiblock copolymer poly(sulphonate phenylene)-b-poly(arylene ether ketone) with different block ratios, by using small-angle neutron scattering technique. A scattering maximum (ionomer peak) at high-q range is shown commonly in both dry and wet states, with q being the magnitude of the scattering vector, while it shifts towards low-q region in the wet state due to the swelling of the ionomer domains with water. The swelling effect also results to a second scattering maximum in the middle-q range because of the water-induced microphase separation. The morphology in this q-range was elucidated in terms of Hard-Sphere model with Percus-Yervick interference approximation.

被引用回数：25 パーセンタイル：80.11(Chemistry, Physical)We investigated the interplay between morphology and properties of a new graft-type of anion exchange membranes (AEMs) containing 2-methylimidazolium groups by using contrast variation small angle neutron scattering (SANS) technique. These AEMs prepared by radiation-induced grafting of 2-methyl-1-vinylimidazole and styrene into poly(ethylene-co-tetrafluoroethylene) (ETFE) films, possessed both high alkaline durability and high conductivity. The SANS measurement reveals that these membranes are consisted of three phases: crystalline lamellar and crystallite domains originating from the pristine ETFE, which offer good mechanical properties, hydrophobic amorphous domains, which offer a matrix to create conducting regions, and interconnected hydrated domains, which are composed of the entire graft chains and water and play a key role to promote the conductivity.
