incident refers to a state in which nuclear fission occurs in a self-sustaining way as seen in nuclear power reactors.
The survey centers on checking operation manuals for the prevention of criticality
accidents in which a self-sustaining nuclear fission chain reaction occurs, records of equipment operation, and the nature of safety training given to employees.
He said that since he took the post in July 1994 the company had not carried out training for a possible criticality
At least 49 people were exposed to high levels of radiation in the criticality
accident, which involved a nuclear fission chain reaction.
Because the uranium that triggered the accident was in the form of a solution, it is believed the state of prompt criticality
passed into delayed criticality
with an expansion in the solution shortly after nuclear fission.
There has been a tendency to depict the criticality
accident as a unique catastrophe that could only happen at firms that fall into a special category.
Nuclear Power Corporation (NPC), which finished initial fuel loading at the Kudankulam plant, is to soon seek the Atomic Energy Regulatory Board (AERB) approval to close the reactor vessel before beginning the process for the reactor to attain criticality
The commission advised nuclear plant operators to ensure that their workers receive proper training and education on criticality
The conference held every four years discusses the issues surrounding nuclear criticality
of scenarios submitted in Table 6 are presented in Fig.
However, this is not the first time Arihant has violated a deadline -- the nuclear reactor, for example, was much behind schedule when it achieved criticality
on August 10.
Manmohan Singh, on Saturday, congratulated officials and scientists of the Department of Atomic Energy, Indian Navy and the Defence Research Development Organisation (DRDO) on the INS Arihant, India's first nuclear submarine, achieving criticality
