Nuclear plant in Bangladesh

The word "nuclear" invokes, power plants that depend on atomic energy don't operate that differently from a typical coal-burning power plant. Both heat water into pressurized steam, which drives a turbine generator.Nuclear plants depend on the heat that occurs during nuclear fission, when one atom splits into two.
Nuclear plant provide about 15 % of the world electricity in 2007.In 2008 there are more than 430 operating nuclear power plant.
Now question is what is the problem about Nuclear plant?
Answer is Nuclear Waste.Nuclear waste is the radioactive waste left over from nuclear reactors, nuclear research projects, and nuclear bomb production. Nuclear waste is divided into low, medium, and high-level waste by the amount of radioactivity the waste produces.
In the United States alone "millions of gallons of radioactive waste" as well as "thousands of tons of spent nuclear fuel and material" and also "huge quantities of contaminated soil and water."In the U.S. alone, fossil fuel waste kills 20,000 people each year.Some nuclear waste has very long life time { Tc-99 (half-life 220,000 years) and I-129 (half-life 17 million years) } which dominate spent fuel radioactivity after a few thousand years. The most troublesome transuranic elements in spent fuel are Np-237 (half-life two million years) and Pu-239 (half life 24,000 years).[21] Nuclear waste requires sophisticated treatment and management in order to successfully isolate it from interacting with the biosphere. This usually necessitates treatment, followed by a long-term management strategy involving storage, disposal or transformation of the waste into a non-toxic form.On average, a nuclear power plant annually generates 20 metric tons of used nuclear fuel, classified as high-level radioactive waste. Taking every nuclear plant on Earth into account , the combined total climbs to roughly 2,000 metric tons yearly. All of this waste emits radiation and heat, meaning that it will eventually corrode any container and can prove lethal to nearby life forms.

The approval given to Bangladesh by the International Atomic Energy Agency (IAEA) to set up nuclear reactors for power generation is an opportunity that the country should seize in order to cope with the ever-growing demand for electricity. It's also a recognition of the fact that Bangladesh is now considered a stable country where nuclear reactors can be built to meet its development needs through power generation.
However, successful use of nuclear technology will depend on a number of factors.

1. A team of experts has to be appointed to study the issue in detail. We have qualified professionals in this field who will get an opportunity to prove themselves once a nuclear reactor is put in place.
2.The memories of Chernobyl are still fresh in our mind.So its doubly necessary to take the precautions and safety measures to prevent mishaps. Even in the United States and the former Soviet Union nuclear plant accidents took place with disastrous consequences.
3. We have to upgrade our maintenance and supervision methods to internationally acceptable levels to be able to safely run nuclear plants.

So what you think, power generation through nuclear reactors is ideal for Bangladesh ? In the shake of high demand of electricity it is essential for Bangladesh.But it can cause serious damage to the environment due to mismanagement.
