0 earthquake off the Pacific coast caused a seismic shock wave that reverberated throughout northern Japan, the country's nuclear plants shut down automatically, as planned, preventing any further nuclear chain reactions
PNC built Monju, which achieved "criticality," a state of sustained nuclear chain reactions
, in 1994.
Without power, and with damaged pumps, they resorted to using sea water mixed with boron, which disrupts nuclear chain reactions
Nuclear reactors harness the enormous energy released when atoms split apart in nuclear chain reactions
Defense Minister Sergei Ivanov indicated Thursday Russia will continue conducting subcritical nuclear tests that do not cause sustained nuclear chain reactions.
Subcritical nuclear tests are different from traditional nuclear experiments in that they are halted before nuclear materials reach ''criticality,'' in which a nuclear chain reaction is triggered.
It was also in 1934 that SZILARD applied for a patent which described the laws governing nuclear chain reactions.
The work on nuclear chain reaction, undertaken in U.
Physicists calculated how far the P reactor's 427 control rods should be withdrawn to reach criticality -- self-sustaining nuclear chain reactions
A nuclear reactor is a device in which nuclear chain reactions
are initiated, controlled, and sustained at a steady rate, as opposed to a nuclear bomb, in which the chain reaction occurs in a fraction of a second and is uncontrolled causing an explosion.
The three allegedly hurried to complete uranium-processing work, illegally bypassing a required process, without sufficient knowledge of the danger of nuclear chain reactions
