59 megajoules of sustained energy ^over the course of a few seconds^.
Ideally this energy output would be sustained for days within ITER.
JET is not designed to do this, as it has a copper magnet system, which means if you try to sustain such a plasma (confined with around 5 T magnet and around 2 MA plasma current) for longer than a few seconds, you would melt the magnet.
Edit: ITER would operate at 5-10 T, and around 15-20 MA plasma current.
