The Spent Fuel and Radioactive Waste Information System (SRIS) will provide an authoritative and integrated view of national and global spent fuel and radioactive waste inventories as well as relevant laws, regulations, policies, plans and activities. The IAEA is encouraging national authorities to take advantage of this important new tool by nominating representatives responsible for submitting data to SRIS, part of which will be available to the public and other countries using the system. So far, 38 countries have done so.
