ARTICLES RELATED TO Nuclear meltdown - Sequence of events | | | |  Nuclear meltdown - Sequence of events: Encyclopedia II - Nuclear meltdown - Sequence of eventsWhat happens when a reactor core melts is the subject of conjecture and some actual experience (see below).
Before the core of a nuclear reactor can melt, a number of events/failures must already have happened. Once the core melts, it will almost certainly destroy the fuel bundles and internal structures of the reactor vessel (although it may not penetrate the reactor vessel). [Note that the core at Three Mile Island did melt nearly completely but stayed within the reactor vessel.] If the melt drops into a pool of water (for example, ...

| | | | Nuclear meltdown - Sequence of events: Encyclopedia II - Nuclear meltdown - Meltdowns A number of Russian nuclear submarines have experienced nuclear meltdowns. The only known large scale nuclear meltdowns at civilian nuclear power plants were in the Chernobyl accident at Chernobyl, Ukraine, in 1986, and Three Mile Island, Pennsylvania, USA, in 1979 although there have been several partial core meltdowns, including accidents at:
NRX, Ontario, Canada, in 1952
EBR-I, Idaho, USA, in 1955
Windscale, Sellafield, England, in 1957
Santa Susana Field Laboratory, Simi Hills, California, in 1959
Enrico Fermi Nuclear Gen ...

| | | | Nuclear meltdown - Sequence of events: Encyclopedia II - Nuclear meltdown - Reactor design Although pressurized water reactors are more susceptible to nuclear meltdown in the absence of active safety measures, this is not a universal feature of civilian nuclear reactors. Much of the research in civilian nuclear reactors is for designs with passive safety features that would be much less susceptible to meltdown, even if all emergency systems failed. For example, pebble bed reactors are designed so that complete loss of coolant for an indefinite period does not result in the reactor overheating. The General Electric ESBWR and Westingho ...

| | | | Nuclear meltdown - Sequence of events: Encyclopedia II - Nuclear meltdown - Effects The effects of a nuclear meltdown depend on the safety features designed into a reactor. A modern reactor is designed both to make a meltdown exceedingly unlikely, and to contain one should it occur.
In a modern reactor, a nuclear meltdown, whether partial or total, will be contained inside the reactor's containment structure. Thus (in the unlikely event that no other disasters occur) while the meltdown will severely damage the reactor itself, possibly contaminating the whole structure with highly-radioactive material, a meltdown alone will generally not lead to significant radiation release or danger to the public. The effects ...

| | | | Nuclear meltdown - Sequence of events: Encyclopedia II - Nuclear meltdown - Causes In pressurized water reactors, boiling water reactors, RBMKs, and breeder reactors, the core can melt as a result of a loss of coolant accident (in which all emergency core cooling systems have failed). A similar circumstance is created should the steam generator secondary dry-out together with emergency system failure. A rapid loss of water from the reactor system naturally stops the chain reaction. Borated water is injected by the emergency systems and thus in the large-break accidents, control rod insertion is not needed to stop the fissi ...
