Unlike the plant at Three Mile Island, Chernobyl's stricken reactor apparently lacked a sturdy containment vessel, and large amounts of radiation spewed out over an area of 125,000 square miles (323,749 square kilometers). The number of deaths caused by radiation-related illnesses is still ...
4. Russia and 27 other countries have been joining efforts to build a new protective cover for Chernobyl's broken reactor. 5. The Chernobyl reactor had no shell and was also operational when the disaster struck. 6. Cheng said the test was considered a success because the reactor produced pla...

A research reactor is designed to produce various beams of radiation for experimental application; the heat produced...
Kiyoshi Kurokawa, who headed the biggest investigation into the worst nuclear crisis since Chernobyl, described Fukushima as an avoidable "man-made" disaster in his 2012 report. A silo mentality among executives and a collectivist mindset among bureaucrats, which puts organizational interests ahead of ...
This feature allowed one of the Chernobyl reactors to increase its power from below 20% to 100 times full power in about 4 seconds, causing a catastrophe. Furthermore, the large core makes the neutron fluxes in different parts of the core only weakly coupled, e.g. one or more regions of...
The “Chernobyl Unit4” is now in a “large concrete shelter room” that was quickly built so that the other reactors of the power plant could continue to operate. However, the structure is not solid or durable. The international plan for the implementation of shelter in the 1990s included ...
Some reactors also use graphite, although it has a number of problems (see, for example, the Windscale fire and the Chernobyl accident). A reactor that is not moderated is called a fast reactor. The higher neutron flux allows some nuclear reactions to occur that are difficult to arrange in...
