The FBR Cycle Comprehensive Training Facility constructed in the International Cooperation and Technology Development Center (in Shiraki area) was opened in earnest since October in 2000. The facility is mainly with the aim of encouraging in technical skills of the operators and maintenance engineers in the prototype fast breeder rector Monju and also is offered to another center in JNC and the local community as a global training facility. Its facility consists of the called sodium school and maintenance school. It is able to study widely sodium huddling technologies, such as chemical and physical properties of sodium, sodium loop operating skill, sodium fire extinguish and treatment sodium compound, and counter training for sodium piping leakage at the sodium school. While the nine study models are installed in the maintenance school and the trainees can learn not only related Monju inherent maintenance technology but also some general maintenance skills. During for six months, October 2000 to March 2001, the six sodium training courses were held 22 times and the eight maintenance courses were carried out 11 times. Total participated number is 305 and 75 trainees among of them joined from the community. To do the training effectively, as the evaluation and analysis system of training result, the skill confirmation test of which aims to have a grasp training results quantitatively by themselves was devised and was introduced. Almost of the training course's results were improved remarkably such as that average point after getting training were risen level of 80 point from level of 40 point before training. Like this, it is obvious that their skills of the Monju operators and maintenance engineers are advancing toward to Monju restarting.

Three years have passed since the discovery of iron-based superconductors, its maximum superconducting transition temperature () is 55 K, resulting in second highest material system next to cuprate high- superconductors. Among various material systems in iron-based superconductors, we have systematically studied on LaFeAsOF (=28 K) of first discovered system and BaFe(As,P) which have recently attracted tremendous attention by the discovery of line nodes in its order parameter. In the session, we present recent results on "spin fluctuation and superconductivity on LaFePO", and "symmetry of order parameter on BaFe(As,P) by inelastic neutron scattering" studied by the chopper spectrometer 4SEASONS (J-PARC).

We report systematic studies on Fe-based superconductors LaFeAsOF ( =28 K) and BaFe(As,P) ( =31 K) by using inelastic neutron scattering measurement.
