Nuclear Power--Our Future

Thousands of historic period ago piece worlds learned to chance upon fire. By collecting and ardent wood they were able to ardent themselves, wangle food, and manufacture primitive tools. Later, the Egyptians discovered the principal of the sail. even so much recent was the invention of the water wheel. All of these activities implement miscellaneous forms of energy-biological, chemical, solar, and hydraulic. Energy, the ability to do work, is essential for meeting raw material human indigences, extending the life expectancy, and providing a rising living standard. This is where the need for thermonuclear power comes in. Uranium fission is around a one million million times more high-octane than the common practice of burning burn or oil. For comparison, coal combustion produces about 20-30 MJ/kg of heat energy opus uracil, in a warm breeder reactor, produces more than 24,000,000 MJ/kg (Energy 27). Those numbers alone are astounding. Uranium is also exub erant, convey to recent discoveries of large reserves. At present, uracil is only being mined and separated from ore. However, a extensive untapped acknowledgment is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 make headway of sea water contains 4.6x10^9 tons of uranium. All the worlds electrical energy 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 tha t in that many years, half of the uranium wi! ll no overnight 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...
