The Tragedy of the Commons Science 13, December At the end of a thoughtful article on the future of nuclear war, J. It is our considered professional judgment that this dilemma has no technical solution.
This essay discusses some of the major advantages and disadvantages of nuclear energy.
Nuclear power is generated using Uranium, a mineral of which one of the isotopes, U- is unstable. The nucleus breaks down resulting in the emission of heat and radiation followed by a chain reaction. This is called nuclear fission and this process liberates a large amount of energy, but the process also releases radiation which is very dangerous.
What are the Advantages of Nuclear Energy? Clean Energy Nuclear energy has the ability to produce electricity without greenhouse gas emissions. It produces electricity without pollution. It is cleaner than many other forms of energy production.
High Quantities Nuclear reaction releases a million times more energy, as compared to hydro or wind energy. Large quantity of energy is generated from a single nuclear power plant. High Reserves Nuclear reactors make use of uranium as fuel and produces huge amounts of energy from small amounts of uranium.
The Earth has the high reserves of uranium. Current estimates put the uranium supply as enough to last for 30 to 60 years. Moreover other fuel cycles like Thorium are available for power generation. Whereas, oil reserves and other fossil type fuels are likely to run out shortly.
Reliability Nuclear power plants operate reliably and have a continuous output of power. The plants do not generally face operations and maintenance problems.
This is a contrast to other alternative energies which depend on the activity of the weather. Low Operating cost Although nuclear power reactors are expensive to build, they are relatively cheap to operate.
Fuel is inexpensive and a plant can be operated by small number of people, approximately 10 people. Concentration The nuclear energy is by far the most concentrated form of energy, so it can be produced in large quantities over short periods of time. Low Waste Produces small amounts of waste and waste is more compact.Also See WHY STEADY STATES ARE IMPOSSIBLE OVERSHOOT LOOP: Evolution Under The Maximum Power Principle The Tragedy of the Commons Science #13, December Vol.
