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.

This research presents a discrete element method (DEM) model for simulating the vibratory filling of the Idaho calcine waste simulant into various convoluted hot isostatic pressing canisters. The simulation closely emulates the experimental vibratory powder-filling processes, achieving accurate representations of surface profiles and powder bed heights. Notably, the model underestimates lower fill levels but demonstrates improved accuracy at higher levels due to diminished air influence. Executed on a consumer-grade desktop PC, the DEM model replicates tapped powder bed heights to within millimeters, proving its capability to efficiently simulate commercial-scale bulk material handling processes using standard computing hardware.
