Initially developed as a tool for training lead auditors of nuclear quality systems, the Nuclear Auditing Handbook has also been used as a reference by quality managers who plan quality system audits. It provides detailed material in such aspects as the development, administration, planning, preparation, performance, and reporting of quality system audits in energy-related fields. ASQ's Nuclear Committee of the Energy and Environment Division gathered a team of highly seasoned experts in the nuclear auditing field to expand this new edition's content and bring it current to modern-day best practices and standards. This book introduces updated information about requirements and standards, including the 2019 editions of the American Society of Mechanical Engineers (ASME) NQA-1 Quality Assurance Program Requirements for Nuclear Facility Applications and ASME BPVC Sections I; IV; and VIII, Divisions 1 and 2. The authors and editors have also added helpful tools to aid nuclear auditors, including case studies suitable for training auditors, blank forms for convenient use, and samples of completed forms.
