Roundtable, from TRT World, describes itself as a discussion program with an edge. Broadcast out of London, it's about "bringing people to the table, listening to every opinion, and analyzing every point of view." In September 2019, host David Foster invited an illustrious panel to discuss the potential of hydrogen fusion: ITER Director-General Bernard Bigot; Steven Cowley, director of the Princeton Plasma Physics Laboratory and former CEO of the UK Atomic Energy Authority; Mark Wenman, Imperial College London; and Colin Walters, current director of the UK Atomic Energy Authority.

In order to generate large amounts of fusion power, there needs to be a combination of two heavy hydrogen nuclei such as deuterium and tritium. But because of the radioactive nature of tritium—and also its scarcity—most experimental plasmas consist of deuterium only.

Although scientists are able to scale up the predicted performance of deuterium-tritium (DT) plasmas, there is nothing like using the real DT mix itself.

Next year, the European tokamak JET will be re-introducing tritium into its vacuum vessel for the first time since 1997.

The importance of its DT experimental campaign cannot be overstated for ITER. Until ITER starts operation with tritium in 2035, JET tritium and deuterium-tritium experiments will offer fusion scientists the opportunity to investigate physics relevant to high-fusion-power DT plasmas.
