A clean-up crew working to remove radioactive contamination after the Three Mile Island accident. 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".
Nuclear bombs are extremely deadly weapons, but their worst effects are confined to a limited zone. A government safety expert says its entirely possible to survive a nuclear explosion and its ...
Nuclear criticality safety practitioners attempt to prevent nuclear criticality accidents by analyzing normal and credible abnormal conditions in fissile material operations and designing safe arrangements for the processing of fissile materials. A common practice is to apply a double contingency analysis to the operation in which two or more ...
Compressive protection may be provided by inexpensive earth arching. The overburden is designed to shield from radiation. To prevent the shelter from floating to the surface in high groundwater, some designs have a skirt held-down with the overburden. A properly designed, properly installed home shelter does not become a sinkhole in the lawn.
A terrorist-caused nuclear detonation is one of 15 disasters scenarios that the federal government continues to plan for with state and city governments — just in case.
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of ...
The three nuclear engineers gained the attention of journalists and their disclosures about the threats of nuclear power had a significant impact. George Galatis was a senior nuclear engineer who reported safety problems at the Millstone 1 Nuclear Power Plant, relating to reactor refueling procedures, in 1995.
Nuclear weapons states are responsible for working toward disarmament and non-nuclear weapons states must submit to IAEA safeguards. The treaty requires that non-nuclear weapons states conclude comprehensive safeguards agreements under INFCIRC 153. The NPT is the centerpiece of global efforts to prevent the further spread of nuclear weapons. [5]
