BWXT announces nuclear manufacturing plant expansion
BWX Technologies announced today plans to expand and add advanced manufacturing equipment to its manufacturing plant in Cambridge, Ontario, Canada.
A $36.3 million USD ($50M CAD) expansion will increase the plant’s size by 25 percent—to 280,000 square feet—and another $21.7 million USD ($30M CAD) will be spent on new equipment to increase and accelerate its output of large nuclear components. The investment will increase capacity and create more than 200 long-term jobs for skilled workers, engineers, and support staff, according to the company.

DIII-D has studied thermal and particle transport in International Thermonuclear Experimental Reactor (ITER)-relevant regimes. In order to better distinguish between thermal transport models, it is important to test both the steady-state and time-dependent predictions of models against experimental results. Based on experiments in DIII-D, models containing the full spectral range of drift wave physics from ion temperature gradient to electron temperature gradient modes were in closest agreement with experimental observations. Inclusion of E × B flow shear stabilization effects was found to be important. Although some aspects of the experimental observations were well matched by various models, no individual model did well matching both the equilibrium and time-dependent electron and ion behavior, which clearly indicates that further improvement in transport models is required. Helium transport studies in DIII-D are encouraging for ITER in that they indicate that the measured particle diffusivity is sufficient to remove helium ash fast enough to avoid deleterious fuel dilution, but other factors for ITER such as divertor geometry and pumping speed must also be assessed.
