Technical and Commercial Feasibility Assessment of Nuclear Microreactors as a Clean Energy Source for Data Centers and Mining Sites
… assumptions, Nuclear Microreactors appear to be cost-competitive for different scenarios. Simulations show that nuclear-based systems outperform, in Net Present Cost and Levelized Cost of Energy, diesel-based ones across most of the sensitivity cases tested. Results suggest that, when available, …
