TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The Cs2LiYCl6:Ce3+ (CLYC) scintillator is being widely employed in nuclear physics, planetary science, radiation environmental monitoring, nuclear security, and nonproliferation communities. The time resolution of a 1 × 1-in. CLYC scintillation detector is reported in this paper. It was measured by the use of a high sampling rate DRS4 waveform digitizer and an EJ-309 liquid scintillation detector. The digitizer was first characterized with regard to its intrinsic time resolution and then the time resolution of the EJ-309 detector was investigated. It served as a reference detector in the time resolution measurements for the CLYC detector. The time pick-off techniques used were the constant fraction discrimination and leading edge discrimination methods. In addition, the Savitzky-Golay filter was used to further improve the measured time resolutions. This filter was shown to be an effective approach to improving time resolution when the signal-to-noise ratio is low.
