What are disadvantages of the use of nuclear power for energy?

Answer 1

• The waste is hazardous and difficult to store.
• There is some potential danger in operating a nuclear power plant (cf. Chernobyl and Three Mile Island), but the principal disadvantage is the need to safely store the spent fuel for tens of thousands of years.
• With proper regulation, safety features, and common sense pretty much none. When you test a poorly designed reactor, lets say a light water graphite moderated reactor also know as an RBMK reactor (Chernobyl) under low power low coolant conditions with al of the safety features turned off things can happen. When you ignore what the computers when they say to shut down the reactor and keep it running (Three mile island) things happen. But if you need disadvantages:
• Radioactive Waste
• Higher level waste can be reprocessed into Plutonium either through the use of a reprocessing facility or can be prevent from being made by using a breeder reactor where the higher level waste is not made and enriched Plutonium is made instead.
• Proliferation of fissionable materials
• The problem with breeder reactors is also the reason why they are good.They produce more fuel but they produce more fuel this highly enriched fuel can be used to make nuclear weapons, dirty bombs, or be used in a nuclear reactor to make energy.
• There is a large safety risk, from accidents and from terrorists stealing the fuel/byproducts to make weapons of mass destruction, nuclear power plants cost a lot to start, the nuclear fuel is non renewable and there is only enough to last approx 70 years.
• Nuclear fuel is in fact renewable in so-called "breeder" plants. France uses them, though there are none in the US.
• Nuclear plants are quite expensive to build, but so are coal-powered plants of equivalent capacity. Several companies are working on low-capacity plants... enough to power a neighborhood or a small village... that would be much cheaper.
• One disadvantage not mentioned above is the problem of disposing of spent... but still radioactive... fuel.

Answer 2

Nuclear explosions (from atomic bombs used in wars) create radiation, this radiation harms the cells of the body which can make people sick or even kill them.

Nuclear reactors for civil purposes have waste disposal problems that emit dangerous radiation. However, currently there many mature methods for dealing with, storage, and/or disposal of wastes from nuclear nuclear reactors safely and without negatively affecting the environment.

Answer 3

A nuclear power plant represents an environmental disaster waiting to happen. Lots of these facilities have been operating, and continue to do so quietly. When will we see the next Chernobyl?

A:(Chernobyl was a defective design that got implemented without government regulation, it allowed a feedback loop, Nuclear Power Plants designed in America and all over the world today are designed with fail safes at every level).

Designs are not perfect, and the people who operate the plants make mistakes, as we have seen. The city of Prypiat, Ukraine, which is near Chernobyl, was effectively a "brand new" city. It was literally abandoned by every resident and is now a ghost town, and all because of radiation from the Chernobyl disaster.

A:Nuclear power plants continue to generate tons of extremely radioactive material as they burn through the fuel in their reactor cores (using only a fraction of it). There are no permanent storage facilities for this material yet, and it must be safeguarded for many hundreds if not thousands of years. A:Anyone operating a nuclear reactor can generate weapons grade plutonium. Additionally, the plants could be targets for sabotage or terrorism of some kind. There is a serious downside to operating nuclear power plants, and as citizens with the right to vote, we should know something about the risks so we can make informed decisions about the future of the plants and their spent fuel. A:The waste is very powerful/dangerous. The health of the humans living along with a nuclear plant is in grave danger, it is hazardous for them to live with that kind of product of technology. It is not the people living along with the plant that will benefit from the good things produced by it.

there is no known way to safely dispose of the waste a nuclear power plant causes

And if something goes wrong with a nuclear power plant it can be disastrous for the people working at the plant; the people living near the plant; and even the people living hundreds of kilometres away, for possibly decades after. Think.. Chernobyl.

>Extremely radioactive nuclear waste is produced by nuclear power plants.!!

>Causes ionization of air......

> nuclear radiations can cause health problems

• >Careless disposal of waste in the past has led to pollution of land, rivers and the ocean
• >It has to be operated at full load throughout for a good efficiency. So part load operation becomes inefficient.

  >Capital cost of small size plants is very high.

There are numerous apparent disadvantages to nuclear power plants. Enviromentally speaking, nuclear waste is very harmful and hard to deal with safely, and nuclear power is not a renewable source. Alternative reasons can be that they are generally ugly to look at, and have numerous safety risks leading to monumental security and safety measures which in turn lead to very high running costs on top of the cost for resources and maintainance.

We can also cite Fukushima as an example. The Fukushima disaster has really put a damper on the entire nuclear industry and uranium companies.

disadvantagesSome of the disadvantages of nuclear power :

• Nuclear Power generates radiation, which can be harmful or even fatal to infected people.
• A nuclear meltdown can often occur which will release massive amounts of radiation into the community.
• Extremely radioactive nuclear waste is produced by nuclear power plants. This stuff can't be just thrown out. The US plans to move all its nuclear was to an underground dump by the year 2010. Currently it is stored in the plants.
• Nuclear waste dumps can spontaneously combust without warning.
• Nuclear reactors only last for about forty to fifty years, so where they are extremely productive, they break down and are costly to replace.
• There are international dangers too. Some reactors produce plutonium which can be used to make nuclear weapons. If the whole world were to use these, they would have unlimited access to nuclear weapons.

• Poisonous waste is produced; some of which is highly radioactive.

• Disposal of this radioactive waste has not been safely achieved.
• The power station is very expensive to build. When the costs are taken into account, the electricity produced by the power station is relatively expensive.
• Careless disposal of waste in the past has led to pollution of land, rivers and the ocean.

A:The only con to nuclear power is the storage of spent fuel and contaminated rags and such. A:The good part is the power, the bad part is the waste, you know how they use uranium to heat up the water, what do they do with the leftover uranium?, they dump it causing a threat to life with nuclear toxins, theses areas can take millions of years to be completely safe, of course. A:It's a matter of opinion really. They do have the potential for environmental damage and damage to people's health, as in the Chernobyl disaster, and must be designed and operated to the highest standards, but do offer useful amounts of power using fuel which can be obtained from friendly countries, so they do benefit the economy. A:It's a matter of opinion, but note that no large scale harnessing of energy is without some adverse effect on people and environment

Answer 4

First of all, there are two types of nuclear energy. The first is nuclear fission, which is is what the question most likely is referring to. Nuclear fission is the same process that is used in nuclear bombs, in which atoms are split apart to release massive amounts of heat. The waste product is extremely radioactive, meaning that it is harmful to living organisms like humans and animals.

The other type is called nuclear fusion, where two atoms are fussed together to release energy. this form of energy produce no harmful waste. However, the activation energy is much higher, and the energy difficult to capture.

Answer 5

Nuclear fission produces nuclear waste which has to be desposed off and because of the nuclear waste's long half-life it takes thousands of years before the waste becomes safe. Mining for U-238 is expensive and an enrichment process is required to turn U-238 to U-235 before it can be used in a nuclear reactor, this takes time and money and is another disadvantage.

Answer 6

you might run out. that's why the sun will die one day.

Answer 7

the fuel and the waste products of nuclear reactions are very dangerous to living organisms

Answer 8

The biggest disadvantage of nuclear power is the waste generated. This waste is highly radioactive and lasts for a long time.

Answer 9

Its expensive and dangerous : the plant needs to be large and complex, the waste is hard to store, it can be used as a weapon source.

Answer 10

it can be very dangerous if not careful
