Notes:
1. The IAEA classification of "in operation" includes all reactors which have at any time operated except those permanently shut down.
2. The table shows the reactor at Trino (Italy) as permanently shut down. However, although it was taken out of operation for decommissioning several years ago, it has been undergoing updating work and is expected to operate again shortly.
3. The figures for reactors "in operation" include 5 reactors in OECD countries which have been subject to longer term shutdowns pending completion of remedial work or licensing procedures.
