Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a loss of coolant or loss of coolant flow).
Under normal conditions, nuclear power plants receive power from generator. However, during an accident a plant may lose access to this power supply and thus may be required to generate its own power to supply its emergency systems. These electrical systems usually consist of diesel generators and batteries.
Without a long-term solution to store nuclear waste, a nuclear renaissance in the U.S. remains unlikely. Nine states have "explicit moratoria on new nuclear power until a storage solution emerges". [17] Some nuclear power advocates argue that the United States should develop factories and reactors that will recycle some of the spent nuclear ...
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".

Near her home, Thomas points out Texas' largest coal-fired power plant. "It's the oldest thing you can be burning in our neighborhoods. It's dangerous," Thomas said.
Amtrak said Tuesday afternoon a brush fire close to its tracks in the Bronx left trains in the area without power, forcing the agency to suspend the heavily used service connecting New York Penn ...
Instead, they manage workers' exposure by setting rules like limiting work times in contaminated areas. However, these measures have limitations since they don't address the hazard itself. Where possible, administrative controls should be combined with other control measures. [17] Examples of administrative controls include:
