Introduction to Nuclear Safety provides a comprehensive introduction to the field of nuclear safety. It covers why safety cases are produced, how safety cases are produced and what is then done with them on nuclear plants and is based on the author’s extensive industry experience. The book encompasses many different topics in the field of nuclear safety and answers the need for an accessible introductory text to complement industry guidance. It focuses on the principles and applications of nuclear safety, guiding the reader through the ‘why’ and the ‘how’ of constructing a nuclear safety case. The theory is enhanced by the provision of examples on how safety cases may tackle a particular problem and it provides the ideal stand-alone text for training courses. The book adopts a consensus approach to the various methodologies used in the industry and, armed with such knowledge, an individual should have a good grounding for the application of nuclear safety in the manner required for their industry. Introduction to Nuclear Safety describes why we pursue nuclear safety, including the legal, financial and moral reasons. The fundamental concept of reducing risks to as low as reasonably practicable in the nuclear industry is discussed and the safety case life-cycle from design to commissioning to operations and decommissioning is described.
