For example, touching or standing around an antenna while a high-power transmitter is in operation can cause burns. The mechanism is the same as that used in a microwave oven. [6] The heating effect varies with the power and the frequency of the electromagnetic energy, as well as the inverse square of distance to the source. The eyes and testes ...
An event that could prevent both offsite power, as well as emergency power is known as a "station blackout". [124] In 2011, an earthquake and tsunami caused a loss of electric power at the Fukushima Daiichi nuclear power plant in Japan (via severing the connection to the external grid and destroying the backup diesel generators). The decay heat ...
Shock danger may be reduced by use of an extra-low voltage electrical system that is unlikely to expose a human to dangerous levels of current. Special isolated power systems may be used in applications such as operating rooms, where electrical equipment must be used in proximity to a person unusually vulnerable to electrical shock.
Non-proliferation policy experts have questioned "the use of private contractors to provide security at facilities that manufacture and store the government's most dangerous military material". [3] Nuclear weapons materials on the black market are a global concern, [ 4 ] [ 5 ] and there is concern about the possible detonation of a dirty bomb ...
The RBMK tends towards dangerous power fluctuations. Control rods can become stuck if the reactor suddenly heats up and they are moving. Xenon-135, a neutron absorbent fission product, has a tendency to build up in the core and burn off unpredictably in the event of low power operation. This can lead to inaccurate neutronic and thermal power ...
Transformers are crucial to the grid because they change the voltage of electricity to make it usable.
Nuclear power plants are a complex energy system [189] [190] and opponents of nuclear power have criticized the sophistication and complexity of the technology. Helen Caldicott has said: "... in essence, a nuclear reactor is just a very sophisticated and dangerous way to boil water—analogous to cutting a pound of butter with a chain saw."
