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
Negotiations leading to the Joint Comprehensive Plan of Action the United States House Committee on Foreign Affairs and expressed great concerns about the Arak nuclear reactor facility. "Now, we have strong feelings about what will happen in a final comprehensive agreement. From our point of view, Arak is unacceptable. You can't have a heavy-water reactor," he said. President Barack Obama, while addressing the House of Representatives and Senate, emphasized that "these negotiations do not rely on trust; any long-term deal we agree to must be based on verifiable action that convinces us and the international community that Iran is not building a nuclear bomb."
