A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
What happens when a nuclear power plant stops working?
When a nuclear reactor stops operating, it must be decommissioned. Decommissioning involves safely removing from service the reactor and all equipment that has become radioactive and reducing radioactivity to a level that permits other uses of the property. The U.S. Nuclear Regulatory Commission has strict rules governing nuclear power plant decommissioning that involve cleanup of radioactively contaminated power plant systems and structures and removing the radioactive fuel.
What is the radioactive element in nuclear waste?
By volume, most of the waste related to the nuclear power industry has a relatively low level of radioactivity. Uranium mill tailings contain the radioactive element radium, which decays to produce the radioactive gas radon. Most uranium mill tailings are placed near the processing facility, or mill, where they come from.
How long can radioactive waste be dangerous?

Why do power plants produce high voltage electricity?
Centralized power plants produce high-voltage electricity to facilitate the transmission of the electricity over long distances and lessen the amount of electricity lost to friction in the wires. High-voltage transmission lines typically carry the electricity to a substation.
How does a power plant generate electricity?
After a centralized power plant generates electricity, the electricity must be delivered to the end-user. This delivery happens in three steps: 1 Transmission. Centralized power plants produce high-voltage electricity to facilitate the transmission of the electricity over long distances and lessen the amount of electricity lost to friction in the wires. High-voltage transmission lines typically carry the electricity to a substation. 2 Substation. Substations are used to condition electricity as it moves through the grid. Substations can include switching, protection, and control equipment; capacitors; voltage regulators; and transformers. Substations can either “step down” or “step up” high- or low-voltage electricity to prepare it for further transmission or distribution. 3 Distribution. The distribution portion of the electric grid comprises lower voltage power lines that deliver electricity to end-users. Distribution networks tend to span shorter distances and involve delivery of electricity that has voltages common to end-user needs (e.g., 120 volts for a typical home).
How do utilities respond to demand?
If consumers demand more electricity than baseload power plants can provide, operators respond by increasing production from centralized generation facilities that are already operating at a lower level or on standby, importing electricity from distant sources, or calling on end-users who agreed to consume less electricity from the grid through demand response programs. Improving the ability to balance electricity demand and supply is one reason investments are being made in energy storage and modernizing the electricity grid.
How do utilities and other grid operators work together?
Utilities and other grid operators work together to generate and deliver electricity where and when it is needed. For the most part, electricity needs to be generated when it will be used. These needs fluctuate depending on the day, the time, and the weather.
Why are investments being made in energy storage and modernizing the electricity grid?

When power lines and their access roads are placed in undeveloped areas, they can disturb forests, wetlands, and other natural areas.
Does generation capacity fluctuate?
Generation capacity availability can also fluctuate. For example, the amount of sunlight that can be captured by solar photovoltaic panels and converted to electricity depends on the weather (sunny or cloudy) and the angle of incoming sunlight (which depends on the season and time of day).
How do power plants generate electricity?
These power plants do this by primarily heating fossil fuels, which heats up water into steam. The steam moves through a turbine, which generates the electricity, and then it is condensed and recycled back to its pre-heated starting point.
What gases are released from power plants?
Sulfur dioxide is another gas that is released from power plants. Whilst it is technically not a greenhouse gas, it is known to have indirect effects to the atmosphere because it can affect the scattering of incoming sunlight, the formation of clouds and precipitation patterns. So, in many cases, it is considered an indirect greenhouse gas. Sulfur dioxide forms sulphuric acid in the atmosphere.This can then return to Earth as acid rain and impact various ecosystems. The level of sulfur dioxide released from thermal power plants depends on the amount of sulfur in the coal that is used—where the coal used has on average between 0.1 and 3.5% sulphur depending on which type is used. Thermal power plants are also the largest emitters of sulfur dioxide worldwide.

How does thermal pollution affect the environment?
When the water in a power plant is no longer usable, it often gets discharged into a local waterway. This wastewater generally has a higher temperature than the local natural water, so it can increase the temperature of the water, which in turn can have a negative impact on the local ecosystem. Moreover, this wastewater often contains metals and metalloids which have dissolved—such as boron, arsenic and mercury—which can also affect the balance of the local ecosystem.
What are the main contributors to the global nitrogen oxide level?

How does wind power affect land use?
The land use impact of wind power facilities varies substantially depending on the site: wind turbines placed in flat areas typically use more land than those located in hilly areas. However, wind turbines do not occupy all of this land; they must be spaced approximately 5 to 10 rotor diameters apart (a rotor diameter is the diameter of the wind turbine blades). Thus, the turbines themselves and the surrounding infrastructure (including roads and transmission lines) occupy a small portion of the total area of a wind facility.
How do wind turbines affect wildlife?
A recent National Wind Coordinating Committee (NWCC) review of peer-reviewed research found evidence of bird and bat deaths from collisions with wind turbines and due to changes in air pressure caused by the spinning turbines, as well as from habitat disruption. The NWCC concluded that these impacts are relatively low and do not pose a threat to species populations [ 5 ].
How much land is used for wind turbines?
A survey by the National Renewable Energy Laboratory of large wind facilities in the United States found that they use between 30 and 141 acres per megawatt of power output capacity (a typical new utility-scale wind turbine is about 2 megawatts). However, less than 1 acre per megawatt is disturbed permanently and less than 3.5 acres per megawatt are disturbed temporarily during construction [ 1 ]. The remainder of the land can be used for a variety of other productive purposes, including livestock grazing, agriculture, highways, and hiking trails [ 2 ]. Alternatively, wind facilities can be sited on brownfields (abandoned or underused industrial land) or other commercial and industrial locations, which significantly reduces concerns about land use [ 3 ].
Why do offshore wind turbines require more space?
Offshore wind facilities require larger amounts of space because the turbines and blades are bigger than their land-based counterparts. Depending on their location, such offshore installations may compete with a variety of other ocean activities, such as fishing, recreational activities, sand and gravel extraction, oil and gas extraction, navigation, and aquaculture. Employing best practices in planning and siting can help minimize potential land use impacts of offshore and land-based wind projects [ 4 ].
