A group named as "The group for investigation of reasonable safety assurance based on graded approach", which consists of about 10 staffs from Sector of Nuclear Science Research, Safety and Nuclear Security Administration Department, departments for management of nuclear facility, Sector of Nuclear Safety Research and Emergency Preparedness, aims to realize effective graded approach (GA) about management of facilities and regulatory compliance of JAEA. The group started its activities in September, 2019 and has had discussions through 10 meetings and email communications. In the meetings, basic ideas of GA, status of compliance with new regulatory standards at each facility, new inspection system, etc were discussed, while individual investigation at each facility were shared among the members. This report is compiled with expectation that it will help promote rational and effective safety management based on GA by sharing contents of the activity widely inside and outside JAEA.

Basic study on remote analysis by combination of LIBS and AIRAS were performed. For the impurity measurement, detection linearity to % order, the detection limit of order 100 ppm and the error of about 
3% based on statistical fluctuation were obtained by the use of Lanthanide or Uranium oxide sample. For the isotope analysis, by using the laser system specialized for the resonance spectroscopy, spectrum resolution of 800 MHz was performed and 
U in natural uranium was clearly detected. These results suggest that the combination of LIBS and AIRAS will be one of the alternative techniques applicable for the safeguards analysis of next generation fuels without neutron detection by 
He gas. In the next stage, we are going to apply this remote analysis to the measurement of Pu in MOX fuel. In this program, we develop the compact system inside the grove-box and will plan to accomplish the elemental and isotopic analysis of Pu and U within several ten minutes.
