We perform systematic calculations of nuclear moments and energy levels in neutron-rich Na isotopes with the Monte Carlo shell model by adopting a large model space consisting of the full and part of the orbits. The calculation well reproduces those observables. The result shows that the disappearance of the magic number starts already at and that the magicity completely disappears for the isotone $^{30}$ Na. This is in sharp contrast to previous consensus that the magic number disappears at and beyond. This early onset of disappearance indicates that the shell gap considerably narrows in Na isotopes compared to stable nuclei near $^{40}$ Ca.

Performance assessment in geosphere for the JNC's 2nd progress report was based on nuclide migration calculation results by discrete fracture network model. The channel network model approximated from fracture network model with considering fracture connectivity was applied for nuclide migration analysis, since fracture network model had too large data to calculate nuclide migration. However, there are many options in the process of approximation from fracture network model to channel network model. In case of analyzing nuclide migration for above report, so-called "base case", one option was chosen from many options, arbitrarily. In this report, the sensitivity of these options to nuclide migration calculation results was studied. As a result, there was no significant impact to nuclide migration although connectivity of channel and flow characteristics of the model slightly changed among different options. Based on above studies, we concluded that an option used for the base case was appropriate.
