Until such storage is available, the spent nuclear fuel is stored in interim facilities that exist at all nuclear power plant sites. Nuclear power emits low levels of CO 2 across the entire life cycle. The management of high-level waste such as spent nuclear fuel requires storage in secure facilities for an extremely long time.
gorriconjung.tk The facilities must meet the requirements for radiation protection for up to , years. It is the operator's responsibility to have reliable solutions for managing nuclear waste.
Uranium mining to manufacture nuclear fuel has an impact on nature. Modern mining methods allow for the landscape to be restored once mining operations have finished. The construction of new nuclear power plants requires the use of energy-intensive materials, such as metal and concrete, but once a nuclear power plant is up and running it emits exceptionally low amounts of CO 2.
To get a comprehensive overview of the total emissions in relation to nuclear power, we have carried out an Environmental Product Declaration, EPD. EPDs are updated on a regular basis and they help us identify where we should focus our future efforts to keep reducing our emissions even further.

Sourcing nuclear We aim to set and maintain high standards on our fuel sourcing. Read more about nuclear fuel sourcing. What are the biggest environmental threats from nuclear power?
Is nuclear power a bad energy source? Nuclear waste management High-level, long-life radioactive waste, primarily consisting of spent nuclear fuel, must be carefully shielded during handling and transportation. Nuclear waste management in Sweden Radioactive waste in Sweden is classified in four levels and depending on the radionuclide content in the waste it is also classified as long-lived or short-lived waste.
Nuclear waste management in Germany In , the German Bundestag passed a law under which responsibility for the intermediate and final storage of nuclear waste was transferred to the state. Explore our power plants. Nuclear power and the environment Nuclear power emits low levels of CO 2 across the entire life cycle. Environmental Product Declaration for nuclear. Nuclear decommissioning Vattenfall has established the Business Unit Nuclear Decommissioning to perform a safe and efficient decommissioning of reactors in Germany and Sweden.

Waste can be used as fuel instead of being sent to landfill. Take, for example, iodine, a radioactive isotope of iodine that living cells treat just like regular iodine. A smoke plume like Chernobyl's contains lots of iodine, which can drift hundreds of miles. It can end up in rivers and make its way into plants, animals and humans. Our thyroid glands rely on iodine and will absorb iodine just like ordinary iodine, creating a long-term source of serious radiation inside our bodies.
This is why, in the immediate aftermath of nuclear disasters, people in the impacted area are supposed to take iodine pills, to fill up their body's reserves and prevent their thyroids from absorbing any of the radioactive isotopes. Dumping sand and boron the actual Chernobyl mixture also included clay and lead is an attempt to solve both the first and second problems. The sand smothers the exposed reactor, squelching that deadly smoke plume.
And the boron, in theory, could squelch the nuclear reaction. To get a nuclear chain reaction going, she explained, you need to get enough radioactive isotopes close together that their neutrons, firing wildly into space, tend to slam into other atomic nuclei, splitting them. But boron tends to just absorb the neutron. Due to its nuclear structure, it's sort of neutron-thirsty. So, dump enough boron onto the exposed reactor No.
In Chernobyl's case, however, dumping the boron and other neutron absorbers onto the reactor turned out not to work, in part due to the ad hoc helicopter-dumping approach that the plant's design necessitated. Still, Huff said, the principle the Soviets used — neutron absorbers to stop the reaction, coupled with materials to knock the radioactive isotopes out of the air — was sound. And in the event of a similar disaster today, response teams would take an approach based on the same underlying theory. The big difference, she said, is that modern nuclear plants at least in the United States are designed to do a lot of that work themselves.
Huff pointed out at length that U. And the buildings themselves are designed to do much of the work to squelch a nuclear reactor fire and a radioactive plume, she added.
Modern reactors are outfitted with chemical sprays that can flood a reactor building, knocking radioactive isotopes out of the air before they can escape. And unlike Chernobyl, nuclear facilities in the U.
These sealed shells are over-engineered to the point that, in theory at least, even a significant explosion wouldn't breach them. You could crash a small jet into the side of one of these buildings, and it wouldn't expose the core. In fact, as part of a test, the U. The NRC states that studies regarding large jet impacts are still ongoing. All that makes a Chernobyl-scale disaster unlikely, though the Union of Concerned Scientists writes that smaller but still-dangerous radiation leaks are a real threat for which the United States is not adequately prepared. That said, the U.
Nuclear Regulatory Commission NRC has, for every one of the 98 nuclear power reactors operating in the country, drafted emergency handbooks hundreds of pages long. These lay out instructions for what responders should do in the event of all sorts of somewhat-plausible to highly unlikely emergencies. Those handbooks are available in plain English on the NRC's website.
