JET ceases plasma operations after 105,842 pulses
JET ended plasma operations at the end of 2023 after 105,842 pulses and entered decommissioning. With its closure, the world lost its only operating machine licensed and equipped for full deuterium-tritium campaigns; no device is expected to run deuterium-tritium at comparable scale until ITER's declared deuterium-tritium phase. The practical consequence is a long gap in tritium-burning operational experience.
Historical — it happened, and the record is settled.
