GE Hitachi forming supplier group for BWRX-300 SMR
GE Hitachi Nuclear Energy (GEH)—the nuclear business unit of Massachusetts-based GE Vernova in partnership with Japan’s Hitachi—has announced that it is forming a group of qualified supply chain companies to advance the manufacture, commercialization, and international deployment of its BWRX-300 small modular reactor. The company stated that it is forming the group to help ensure “a reliable, cost-effective and innovative” process for getting its SMR commercialized and deployed around the world.

'Trace Tritium Experiments' (TTE) were successfully performed on JET in 2003. The Campaign marked the first use of tritium in JET plasmas since the Deuterium-Tritium Experiment (DTE1) Campaign in 1997, and was the first use of tritium in experiments under the EFDA organisation with the UKAEA as JET Operator. The safety and regulatory preparations for the experiment were extensive. Since JET has been operated by the UKAEA the operations have followed the model of a licensed nuclear site. The safe operation of the JET torus is demonstrated in a safety case. Key Safety Management Requirement (KSMR) and Key Safety Related Equipment (KSRE) are identified in the Safety Case for DT operation. The safe operation of the torus is within the bounds of, and under the control of, an Authority to Operate (ATO). New technical challenges were presented by the need to inject and account for small quantities of tritium in very short pulses (~80ms), with an accurate time stamp. The safety and operational management of the campaign are described. Valuable lessons were learned which would help in running future experiments. It is concluded that JET is in a strong position to run future trace tritium and full DT discharges.
