  Physical incapacitation does not occur within 2 min of exposure. According to the safety approach considered by JAEA, the upper limits of toxic gas concentrations in the control room have been decided sufficiently low such that a min exposure can be permitted. Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards". The IAEA defines nuclear security as "The prevention and detection of and response to, theft, sabotage. The greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal, oil and gas, and the routine health risks are much smaller than those associated with coal. However, there is a "catastrophic risk" potential if containment fails, which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products. M. Laraia, in Environmental Remediation and Restoration of Contaminated Nuclear and Norm Sites, Environmental impacts from coal power plant radioactive effluents and solid waste. Over the past few decades, the general public has become increasingly wary of nuclear power because of concern about radiation releases from normal plant operations, plant accidents and nuclear waste.

Stello, "TMI Action Plan—Status Report," Ap toxic combustion gases th caused severe damag e to the control buil ding and main control room Based on the analysis of the known shell-type nuclear reactors accidents results the. Less soluble gases such as nitrogen dioxide and ozone cause shortness of breath, which may be severe, after a delay of 3 to 4 hours and sometimes up to 12 hours after exposure (see also Air Pollution–Related Illness). With less soluble gases, long-term lung damage can occur and cause chronic wheezing and shortness of breath. Safety of Nuclear Power Reactors. The risks from western nuclear power plants, in terms of the consequences of an accident or terrorist attack, are minimal compared with other commonly accepted risks. Nuclear power plants are very robust. News and information on nuclear power, nuclear energy, nuclear energy for sustainable development, uranium mining, uranium enrichment, nuclear .
