The latest version of JENDL High Energy File (JENDL/HE) and JENDL Photonuclear Data File (JENDL/PD) is being planed to be released as JENDL/HE-2007 and JENDL/PD-2007. In JENDL/HE-2007, nuclear data for about 100 nuclides, which are newly ecaluated and revised from JENDL/HE-2004 will be stored. The JENDL/PD-2007 will have nuclear data for about 170 nuclides.

Hydrogen permselective membranes, which have high hydrogen permeability (approximately 10$$^{-8}$$ $$sim$$10$$^{-9}$$ mol/(m$$^{2}$$ s Pa) with selectivity against water and nitrogen, have been developed by radiation-induced graft polymerization (RIGP) of an acrylic acid (AAc), tetramethoxysirylstyrene (TMSS), and styrene(St) monomers into porous poly(vinylidene fluoride) (PVDF) films. The porosity of the prepared porous grafted PVDF were almost constant against grafting degrees. Thus, by hot press compression, the porosity of the grafted membranes was reduced to a 20-40% level. The hydrogen permeability of the compressed grafted PVDF is 10$$^{-8}$$ $$sim$$10$$^{-9}$$ mol/(m$$^{2}$$ s Pa) with the hydrogen permselectivity of 3.2 and 3.5 against water and nitrogen, respectively. The above results indicate that RIGP of porous films with a hot press process is a very effective method to prepare hydrogen permselective membranes.
