Safeguard System

Since Japan began its nuclear energy research and development fifty years ago, it has considered all possible measures in securing the peaceful use of nuclear energy and has carried them out with transparency.

Specifically, Japan has conformed to bilateral nuclear agreements with the U.S. and other key nuclear nations and to international accords such as the Treaty on the Non-proliferation of Nuclear Weapons (NPT), and has adhered strictly to International Atomic Energy Agency (IAEA) Safeguards.

Safeguards are activities by which the IAEA can verify that a state is living up to its international commitments not to use nuclear programs for nuclear weapons purposes. The Nuclear Non-Proliferation Treaty (NPT) and other international agreements against the spread of nuclear weapons entrust the IAEA as the nuclear inspectorate.

In accordance with national laws, Japan's electric power companies submit reports on material accounting and safeguard activities to Nuclear Regulation Authority (NRA), and accept joint inspections by the IAEA and Japanese authorities to check the reports.
