Webb22 feb. 2024 · The “inherently safe reactor” has been a nuclear industry catchphrase for decades, but the reality has never matched the rhetoric. All it really means is that in certain idealized scenarios, a reactor, after shutdown, could be adequately cooled by passive mechanisms, such as convective airflow. WebbFukushima could “far exceed Chernobyl in terms of the effects on public health.” Many pro-nuclear people came to believe that the accident was proof that the dominant form of nuclear reactor, which is cooled by water, is fatally flawed. They called for radically different kinds of reactors to make the technology “inherently safe.”
Traditional reactor safety systems are active in the sense that they involve electrical or mechanical operation on command systems (e.g., high-pressure water pumps). But some engineered reactor systems operate entirely passively, e.g., using pressure relief valves to manage overpressure. Parallel redundant systems are still required. Combined inherent and passive safety depends only on physical phenomena such as pressure differentials, convection… Webb22 mars 2024 · Dozens of companies are working to develop new nuclear reactors, including so-called Generation IV reactors that are cooled with such materials as molten salts, inert gases, or even liquid metals.
