ABSTRACT
The nuclear power industry is dominated by high safety requirements and low accident probability, but it is essential to have available comprehensive Emergency Arrangements for each station for implementation in the event of an accident. It is difficult to maintain a high degree of preparedness for an event which is unlikely to happen, but the reactor accidents at Three Mile Island and Chernobyl emphasise the need for constant vigilance, not only in preparedness for emergencies, but in all operator activities affecting reactor safety.
