) experiment was performed to study the structure of the Borromean nucleus B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for 
and 
orbitals, and a surprisingly small percentage of 9(2)% was determined for . Our finding of such a small component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in B. The present work gives the smallest - or -orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of or orbitals is not a prerequisite for the occurrence of a neutron halo.

Investigation of oxygen getter option is in progress for FBR MOX fuel to restrain the cladding inner surface corrosion at the high burn-up of 150 GWd/t. Evaluation of the requirement for the oxygen getter materials showed that Zr and Ti were promising candidate materials. Method of loading getter materials into a fuel element was also investigated. Their oxygen uptake ability and restructuring behavior during the oxidation were evaluated by the heating at 1573 K for 10 h under the controlled oxygen potential. As a result, it was shown that both Zr and Ti were available as an oxygen absorber but Ti was superior from the geometrical stability.

Heating tests were carried out for the disc pares of Zr-FMS, Ti-FMS, Zr-UO and Ti-UO to evaluate the compatibility of the candidate materials of oxygen getter with UO and FMS, and the interfaces of each disc were investigated. No reaction was observed between Zr and UO also FMS in the test conditions. For Ti and FMS, Ti-Fe-O phase with the maximum thickness of 14 
m was formed in the Ti disc at 700
C for 100 h but no penetration of Ti into FMS disc was observed. For Ti and UO, Ti-U or Ti-U-O phase were formed near the surface of the Ti disc but these were limited in Ti disc side. No penetration of Ti into UO disc was observed. As a result, it is considered that no harmful influence is expected for Zr and Ti on the integrity of UO and FMS cladding.
