We should build new nuclear power plants Yes because
Increased capacity Increased nuclear capacity in some countries is resulting from the uprating of existing plants. This is a highly cost-effective way of bringing on new capacity. Numerous power reactors in the USA, Switzerland, Spain, Finland, and Sweden, for example, have had their generating capacity increased.
In Switzerlandall operating reactors have had uprates, increasing capacity by Most of the increase is already in place. For instance, the Almarez nuclear plant was boosted by 7. The Ringhals plant was uprated by about MWe over Plant lifetime extensions and retirements Most nuclear power plants originally had a nominal design lifetime of 25 to 40 years, but engineering assessments have established that many can operate longer.
By the end ofthe NRC had granted licence renewals to over 85 reactors, extending their operating lifetimes from 40 to 60 years.
Such licence extensions at about the year mark justify significant capital expenditure needed for the replacement of worn equipment and outdated control systems.
In France, there are rolling ten-year reviews of reactors. There are plans to take reactor lifetimes out to 60 years, involving substantial expenditure. The technical and economic feasibility of replacing major reactor components, such as steam generators in PWRs, and pressure tubes in CANDU heavy water reactors, has been demonstrated.
The possibility of component replacement and licence renewals extending the lifetimes of existing plants is very attractive to utilities, especially in view of the public acceptance difficulties involved in constructing replacement nuclear capacity.
On the other hand, economic, regulatory and political considerations have led to the premature closure of some power reactors, particularly in the USA, where reactor numbers have fallen from a high of to 99, as well as in parts of Europe and likely in Japan.
It should not be assumed that a reactor will close when its existing licence is due to expire, since licence renewal is now common. However, new units coming online have more or less been balanced by the retirement of old units in recent years.
Over75 reactors were retired as 80 started operation. There are no firm projections for retirements over the next two decades, but the World Nuclear Association estimates that at least 80 of those now operating will close by Building more nuclear power stations will be a big start in making that future a reality.
However we have to do it carefully as there are risks with nuclear power and we have to make sure we are safe. Its biggest power company is in talks to join the consortium backing a nuclear power station in Cumbria, in a sign of the continuing allure of Britain’s atomic ambitions to international companies.
Many countries with existing nuclear power programmes either have plans to, or are building, new power reactors.
Every country worldwide that has operating nuclear power plants, or plants under construction, has a dedicated country profile in the Information Library. The ongoing construction of two mega coal power stations at Medupi and Kusile amply illustrates what could happen with the nuclear build.
Work on Medupi commenced in , and was initially. Nuclear power could be the key to a sustainable future where we are not taxing the environment. Building more nuclear power stations will be a big start in making that future a reality.
However we have to do it carefully as there are risks with nuclear power and we have to make sure we are safe. A nuclear power plant or nuclear power station is a thermal power station in which the heat source is a nuclear reactor.
As it is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity.
