why does an rbmk reactor explode?
434276
The interaction of very hot fuel with the cooling water led to fuel fragmentation along with rapid steam production and an increase in pressure. The design characteristics of the reactor were such that substantial damage to even three or four fuel assemblies would – and did – result in the destruction of the reactor.

Sodium metal is kept immersed in kerosene oil to prevent accidental fire. It is very reactive metal and combines explosively with air as well as water. ... Note: Potassium is also kept immersed in kerosene oil for same reason.

One of the modifications to the RBMK reactors included implementing graphite tips to control rods. Uranium used in the reactors has also been specially selected to have low enrichment levels. The Chernobyl series cited the reason for the changes were to ”prevent an accident like Chernobyl from happening again."

Reactor No. 1 and 3 continued to operate after the disaster. Reactor No. 2 was permanently shut down in 1991 after a fire broke out due to a faulty switch in a turbine. Reactors No. 1 and 3 were eventually closed due to an agreement Ukraine made with the EU in 1995.

During an uncontrolled nuclear chain reaction, a radioactive substance gives off energy at a rate that increases rapidly with time, leading to large amounts of radiation and possibly an explosion. ... Fortunately, this occurs with only a few radioactive elements, and only when they are highly purified.

The World Nuclear Association lists ten RBMK reactors that are still operating in Russia (one RBMK was recently decommissioned in Saint Petersburg in 2018). Russia is now the only country with these reactors, which were designed and built by the Soviet Union.

Yes, bomb with an oxidizer will explode in space. The shrapnel will float in space or will orbit a field. The energy will travel in the form of light.

The cylinder can itself become a missile if the cylinder valve is broken off. Compressed gases can cause fires, explosions, oxygen deficient atmospheres, toxic gas exposures as well as the innate physical hazard associated with cylinders under high pressure.

A series of graphite blocks surround, and hence separate, the pressure tubes. They act as a moderator to slow down the neutrons released during fission so that a continuous fission chain reaction can be maintained. Heat conduction between the blocks is enhanced by a mixture of helium and nitrogen gas.

However, if the leakage to earth is small, well below one amp, then the circuit breaker will not react, but the RCD will react to any leakage current over 30mA. This tripping is usually the result of water ingress, such as on the base of your cordless electric kettle, or dampness in mineral insulated heating elements.

An LPG explosion is almost always caused by the accumulation of gas leak in an enclosed space combined with an ignition source, not a Propane-LPG tank explosion (gas cylinder explosion). The leak can be from the gas appliance or other source not involving the bottle.

Aro don't like strong current flow tank, this will make them stress and unstable. The reason for using current flow or wavemake by ppl is mainly for breaking up fights among comm's.

High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn't usually an immediate failure, it takes some time for that heat to build up and do damage.

A peculiarity of the design of the control rods caused a dramatic power surge as they were inserted into the reactor (see Chernobyl Accident Appendix 1: Sequence of Events). The interaction of very hot fuel with the cooling water led to fuel fragmentation along with rapid steam production and an increase in pressure.

Chernobyl was a design flaw-caused power excursion causing a steam explosion resulting in a graphite fire, uncontained, which lofted radioactive smoke high into the atmosphere; TMI was a slow, undetected leak that lowered the water level around the nuclear fuel, resulting in over a third of it shattering when refilled ...

Sodium is high reactive element. If it is kept in open it can explosively react with oxygen to catch fire. Hence to prevent accidental damage sodium is immersed in kerosene oil. ... Because it is highly reactive, and spontaneously combusts when exposed to the air.
