Industry Update—August 2025
Here is a recap of industry happenings from the recent past:
SMR service center targeted for Ontario
GE Vernova Hitachi Nuclear Energy has announced plans to invest as much as $50 million to establish a Canadian BWRX-300 Engineering and Service Center near Ontario Power Generation’s Darlington New Nuclear Project site. The Ontario government had previously approved the construction of the first of four BWRX-300 small modular reactors at the site. The center will provide engineering and technical services for the long-term operation and maintenance of the future fleet of SMRs in Ontario. It will also serve as a hub for innovation and training, knowledge sharing, supply chain engagement, and workforce development.

Two silicon drift detectors combine with the new and nonconventional software pulse-height analyzer (SPHA) to measure the time evolution of soft-X-ray spectra, the thermal electron and superthermal electron temperatures. The high-quality soft-X-ray spectral distributions are easily obtained by the new SPHA. Therefore, the measurement accuracies and the time resolutions of thermal electron and superthermal electron temperatures are also improved. The enhancement phenomenon of superthermal electron avalanche during electron cyclotron resonance heating and the pronounced change for the time evolution of soft-X-ray spectra during supersonic molecular beam injection are observed by this system.
