# Fusion energy record demonstrates powerplant future (UKAEA JET Announcement)

> Official announcement and documentation of JET's record-breaking 59-megajoule fusion test

This press release from the UK Atomic Energy Authority documents the historic milestone where the Joint European Torus (JET) tokamak produced 59 megajoules of sustained fusion energy. It explains the experiment's significance, including sustained power averaging 11 megawatts over five seconds using a deuterium-tritium fuel mix. It serves as essential reference material for understanding modern tokamak engineering progress and the foundation for ITER.

## How it works

In 2022, researchers and engineers at the UK Atomic Energy Authority (UKAEA) facility in Culham/Oxford achieved a record 59 megajoules of sustained fusion energy inside the Joint European Torus (JET) tokamak. This milestone more than doubled the previous sustained fusion energy record set in 1997, utilizing the deuterium-tritium fuel mixture intended for future commercial fusion power plants.
