Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The present schedule of JET includes an experimental campaign with D-T plasmas at the end of the Project programme. A dedicated facility, the Active Gas Handling System (AGHS), has been designed and is being commissioned to process the torus exhaust streams and to recycle tritium and deuterium. The AGHS is expected to process a maximum throughput of 30g tritium daily and total tritium inventory will not exceed 90g. The design is subject to a comprehensive safety analysis which must show that stringent safety criteria are met. In parallel to the AGHS installation, the JET torus and its auxiliary systems are being analysed for compliance with the same safety criteria. Modifications are being implemented where required. The AGHS installation is nearing completion and non-tritium commissioning is underway. The JET D-T phase will be preceded by a very short campaign of a few D-T pulses which can be conducted with a very small inventory of tritium, thus allowing this to be undertaken at an early stage in order to obtain important data prior to the start of the full D-T phase. JET will be the first experimental facility where the tritium fusion fuel processing cycle will be closed (albeit without breeding) and hence important experience and experimental data are expected to be gained for the next generation of fusion devices.
