As you know, there are various power plants, for example, nuclear power plants, coal plants, wind turbines and biomass power plants. The difference between them is the only fuel. In nuclear power plants is uranium fuel. At Ringhals, which is Scandinavia's largest "power plant", the two reactors; Boiling water and pressurized water reactor. But they have more a just one PWR, they have three different net effects. Altogether, the four reactors (R1 in 1976 Boiling water reactor, R2 in 1975 pressurized water reactor, R3 1981 pressurized water reactor, R 4, 1983 pressurized water reactor). Half of our country receive electricity through nuclear power plants!
But there are more and more people are against nuclear power. There are both pros and cons of nuclear power plants.
In: Nuclear is clean and does not increase carbon dioxide, a greenhouse effect, or contamination is not as great as in other ways to produce electricity.! Is more environmentally friendly than other ways to produce electricity. In addition to get more electricity by nuclear power. Nuclear power produces electricity cheap, so it is a low cost! Negative: It becomes very dangerous if the reactor is leaking, it can cause serious harm and even death, in addition, do not disappear radioactivity in a long time, the place where the nuclear power plant has stood can not be farming. The transport of nuclear fuel is very risky for the environment, particularly if the accident occurs.
Ringhals is working vigorously to reduce the negative, primarily nuclear environment. They do this by working diligently with recycling, taking care of the residuum properly, moreover they always try to analyze and improve the safety and environmental performance. And this shows the public. They always choose PROCURER to protecting the environment. But despite all this, there are still negative sides of nuclear power. Small radioactive substances released into the air and it is never good, even if they are temporary and decays quickly. There is a limit which the authorities have set, the limit is on how much radioactivity may be among the people and the environment. But radioactivity is hardly close to the border, maybe about 1% of the limit. The water ends both radio and non radio-active substances. Even if the cooling water is cleaned will still little radioactive and non-radioactive substances into the sea. However, it has not found any negative impact of radioactive discharges. The non-radioactive substances are the same. It has been noticed is the fact that the water released is always 10 ° C degrees warmer than it was in the beginning, and it changes the fish. Those that thrive in warm water increased, while those that thrive in cold water have declined.
Sweden has only two different reactors, boiling water reactor and pressurized water reactor (but there are others that we do not use here, such as heavy-water reactors and light water reactors). Here are some pros and cons with them!
Boiling water reactor; Positive; Since the boiling water reactor is very common, it is also easy to exchange knowledge in the Swedish nuclear power industry. Moreover, it is not so complicated as to the steam generators which do not have pressure water reactor.
Negative: The workforce who work inside the plant is exposed to more radiation and radioactivity emissions are higher and moreover, there are more areas that need to be controlled (in plants). Loading and unloading takes much longer because there are more fuel elements. Radioactive substances released also be printed.
