Nuclear safety

From Wikipedia, the free encyclopedia

This diagram demonstrates the defense in depth quality of nuclear power plants. 1st layer of defense is the inert, ceramic quality of the uranium oxide itself. 2nd layer is the air tight zirconium alloy of the fuel rod. 3rd layer is the reactor pressure vessel made of steel more than a dozen centimeters thick. 4th layer is the pressure resistant, air tight containment building. 5th layer is the reactor building or in newer powerplants a second outer containment building.

Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences.

Many nations utilizing nuclear power have special institutions overseeing and regulating nuclear safety.

Internationally the International Atomic Energy Agency "works for the safe, secure and peaceful uses of nuclear science and technology."

A book by Michael Mehta (2004) entitled Risky Business: Nuclear Power and Public Protest in Canada (Lexington Book), chronicles and analyzes how a small, under-funded public interest group--Durham Nuclear Awareness of Oshawa, Ontario--mobilized opposition to the December 1994 re-licensing of the Pickering Nuclear Generating Station. Mehta explores the struggle between Durham Nuclear Awareness and Canada's nuclear establishment to illustrate how the concept of risk can be used to understand contemporary political conflicts.
