Nuclear Power--Our Future

Thousands of historic period ago piece universes learned to introduce fire. By collecting and ardent wood they were able to loosen up themselves, wangle food, and manufacture primitive tools. Later, the Egyptians discovered the principal of the sail. tied(p) much recent was the invention of the water wheel. All of these activities use miscellaneous forms of energy-biological, chemical, solar, and hydraulic. Energy, the ability to do work, is essential for meeting basic human carrys, extending the life expectancy, and providing a rising living standard. This is where the need for atomic power comes in. Uranium fission is more or less a one million million times more efficient than the common practice of burning char or oil. For comparison, coal combustion produces about 20-30 MJ/kg of heat energy piece uracil, in a warm breeder reactor, produces more than 24,000,000 MJ/kg (Energy 27). Those numbers alone are astounding. Uranium is also enormous, convey to recent discoveries of large reserves. At present, uranium is only being mined and separated from ore. However, a extensive untapped root is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 advance of sea water contains 4.6x10^9 tons of uranium. All the worlds electricity usage, 650GWe could therefore be supplied by the uranium in sea water for 7 million years(Energy 25).

This is a only a theoretical number because it is non likely to name all of the uranium out of our vast oceans. Also, it does not include the fact that in that many years, half of the uranium will no prolonged exist due to hot! decay. So, at worst, we would get about 2 million years of power from it. Thorium is other element than can be used in nuclear reactors. Thorium is approximately foursome times more abundant than uranium. It is obvious that we are...
