The glove used at glove boxes in the nuclear fuel plants is usually made with Chlorosulfonated polyethylene rubber. The rubber is excellent in terms of resistance to radiation because it has no double bond in its main chain of the component, however, it deteriorates rapidly in high dose environment such as direct contact of alpha ray1). Plutonium oxide powder is treated in glove boxes at plutonium fuel facilities where the alpha ray from plutonium oxide power attached on surface of a glove causes the deterioration of the rubber. Therefore the effective method for prevent of the rapid deterioration is to decrease the amount of attached powder, and the glove with conductive property which can prevent static generation on its surface has been developed and tested. The results showed that the rubber has less adherent property to powder compared with conventional one.

We performed Reverse Monte Carlo (RMC) simulations to study the amorphous structure of a heterofullerene, C59N. Neutron diffraction data of the powder sample with about 0.7 g were collected for 16 h at room temperature, using the neutron powder diffractometer NPDF [1] at the Manuel Lujan Neutron Scattering Center of Los Alamos National Laboratory. By using fourier transformation of the scattering function S(Q), the atomic pair distribution function (PDF) of the C59N was obtained.
