Numerous corrections and clarifications: JT60U does not use DT in experiments, the claimed JT60U Q is an estimate from a DD plasma (referenced) |
m "technical capability to use D-T fuel is exhibted in many reactors" is a pointless statement, technically my car could fly but it doesn't. |

Line 4:
Situated on an old [[Royal Navy|Navy]] airfield near [[Culham]], [[Oxfordshire]], in the [[United Kingdom|UK]], construction was started in [[1978]] and the first experiments began in [[1983]].
JET is equipped with remote handling facilities to cope with the radioactivity produced by [[Deuterium]]-[[Tritium]] (D-T) fuel, which is the fuel proposed for the first generation of fusion power plants. Pending construction of [[ITER]], JET remains the only large fusion reactor with facilities dedicated to handling the radioactivity released from D-T fusion
During a full D-T experimental campaign in [[1997]] JET achieved a world record peak fusion power of 16 [[Megawatts|MW]] which equates to a measured [[Fusion energy gain factor|Q]] of approximately 0.7 ([[Fusion energy gain factor|Q]] is the ratio of fusion power to input power, a self-sustaining nuclear fusion reaction would need a value of Q that is greater than 1). As of [[1999]], a higher Q of 1.25 is claimed for the [[JT-60]] tokamak, however this was not achieved under real D-T conditions but estimated from experiments performed with a pure Deuterium (D-D) plasma. Similar extrapolations have not been made for JET, however it is likely that increases in Q over the [[1997]] measurements could now be achieved if permission to run another full D-T campaign was granted. Work has now begun on [[ITER]] to further develop fusion power.
