* Under some categories, there is no facility subject to safeguards inspections. In such cases, "-" are inserted in respective cells.
Categorization is in accordance with the Law for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors (Nuclear Reactor Regulation Law).
When counting the number of facilities and LOFs, the categorization of IAEA safeguards implementation is followed. The categorization does not always correspond with the categorization of domestic regulation.
Minor users are licenced to use natural and/or depleted uranium up to 300g and/or thorium up to 900g.
Number of facilities and LOFs where national inspections were conducted in 2015.
Domestic inspections are normally conducted in conjunction with the IAEA inspections.
Nuclear Material Control Center (NMCC) is designated to carry out domestic inspections under the Nuclear Reactor Regulation Law (Art.61-23-2).
Only the numbers of licence granted for minor users of nuclear material and accounting provisions approved are based on Japanese fiscal year 2016, i.e. April 2016-March 2017.
All licencees except the category of uranium concentration shall have approved accounting provisions to account for and control internationally controled material (incl. nuclear material) properly.

Nuclear material accounting and control is not required, and this type of facilities are not subject to safeguards inspection.
The IAEA conducts CAs based on additional protocol to the safeguards agreement to confirm the absense of undeclared nuclear material and activities. MOFA staff and JSGO inspectors accompany the IAEA inspectors at CAs.(33)Total

The IAEA simultaneously with JSGO, conducts DIVs based on safeguards agreement to verify the correctness and completeness of the design information of facilities provided to the IAEA.

1 Categorization is in accordance with the Law for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors (Nuclear Reactor Regulation Law)
and the relevant cabinet order.
* This table shows the weight of nuclear material subject to each bilateral nuclear cooperation agreement or agreement on the supply of uranium from the IAEA.
Multiple agreements sometimes apply to the same nuclear material. In such cases, the material is counted in multiple times.
