Nuclear Fission

The Controversy About Nuclear Power Plants



There are vehement arguments for and against nuclear power. The various advantages and problems should be thoroughly aired so that the general public can evaluate for itself whether the benefits outweigh the risks. Additional electric power plants will be required in the future to supply a growing world population that desires a higher standard of living.



All methods of producing electricity have serious environmental impacts. The main objections to nuclear power plants are the fear of possible accidents, the unresolved problem of nuclear waste storage, and the possibility of plutonium diversion for weapons production by a terrorist group. The issue of waste storage becomes particularly emotional because leakage from a waste depository could contaminate ground water. Chemical dump sites have leaked in the past, so there is distrust of all hazardous wastes.

The main advantage of nuclear power plants is that they do not cause atmospheric pollution. No smokestacks are needed because nothing is being burned. France initiated a large-scale nuclear program after the Arab oil embargo in l973 and has been able to reduce its acid rain and carbon dioxide emissions by more than 40%. Nuclear power plants do not contribute to the global warming problem. Shipments of fuel are minimal so the hazards of coal transportation and oil spills are avoided.

Environmentalists are divided in their opinions of nuclear power. It is widely viewed as a hazardous technology but there is growing concern about atmospheric pollution making nuclear power more acceptable.

Chain reaction

—An on-going process in which a neutron produced from fission enters a nearby nucleus, causes it to fission, and releases additional neutrons to continue the process.

Critical mass

—The minimum amount of fissionable uranium or plutonium that is necessary to maintain a chain reaction.

Geiger counter

—A small, cylindrical tube used to detect radioactivity, giving an output of voltage pulses when radiation passes through it.

Isotopes

—Two molecules in which the number of atoms and the types of atoms are identical, but their arrangement in space is different, resulting in different chemical and physical properties.

Plutonium

—A man-made element that is created from uranium–238 by neutron bombardment and can be used as a material for fission energy.

Radioactive waste

—The radioactive fragments produced by fission, which accumulate in the fuel rods of a nuclear reactor and eventually must be removed.
