Nuclear meltdown of fission product radioactivity, by simple convection. The second test, deliberate shut-off of the secondary coolant loop that supplies the generators, caused the primary circuit to undergo the same safe shutdown. This test simulated the case of a water-cooled reactor losing its steam turbine circuit, perhaps by a leak. This is a list of the major reactor failures in which meltdown played a role: The China syndrome (loss-of-coolant accident) is a hypothetical nuclear reactor operations accident characterized by the severe meltdown of the core components of the reactor, which then burn through the containment vessel and the housing building, then
Timeline of the Fukushima Daiichi nuclear disaster to take a year. Removed rods will then be moved into a more secure storage. Nuclear scientists in Japan are planning a controlled nuclear meltdown in the hope of learning how to prevent disasters like the one at Fukushima. Using a scaled down version of a nuclear reactor, Tomoyuki Sugiyama, a senior scientist at the Japan Atomic Energy Agency, told MSN Sankei that scientists "want to help improve the accuracy of the Fukushima accident analysis" using the data from their experiment. "We want to study exactly how meltdowns happen and apply what we will learn to help improve ways to
