From the publication:
Introduction Nuclear power is an important source of electricity in Ontario because it produces power safely, economically and cleanly. Its fuel source, natural uranium, is found in abundance in Ontario. Today, the power of the atom supplies more than 40% of the electricity needs of Ontario's homes, schools, stores and industries. Coal-fired and water-powered stations supply the rest. Ontario Hydro operates four nuclear stations with a total of 16 reactors. An additional 5 reactors at two sites are under construction. When all these reactors are operating by the early 1990's, they will help make Ontario much more energy self-sufficient. The generation of electricity from nuclear power results in the production of highly radioactive materials. Harmful amounts of these must be prevented from entering the environment. Ontario Hydro's nuclear stations are designed and built with multiple barriers to safeguard against the release of harmful amounts of radioactive materials. These barriers are designed considering possible equipment failures, design imperfections and operator errors. The barriers are protected by careful plant operation and maintenance, regular testing and inspection of equipment and components, and by the training of reactor operators to respond to normal and emergency conditions. This care and attention to good design and safe operation has resulted in an enviable safety record at Ontario Hydro's nuclear power plants. There has never been a radiation accident which resulted in any injury to any employee or member of the public since Ontario Hydro began operating nuclear reactors in 1962. This booklet explains the principles that provide nuclear station safety. It shows how careful design and operation of these important energy sources protect the people, the water, air and land, the fish and animal life that make up our environment.
