About the BPVC Since its first issuance in 1914, ASME’s Boiler and Pressure Vessel Code (BPVC) has pioneered modern standards-developmen t, maintaining a commitment to enhance public safety and technological advancement to meet the needs of a changing world. More than 100,000 copies of the BPVC are in use in 100 countries around the world. Product Scope / Abstract Provides requirements to maintain the nuclear power plant while in operation and to return the plant to service following plant outages. The rules require a mandatory program to evidence adequate safety and manage deterioration and aging effects. The rules also stipulate duties of the Authorized Nuclear Inservice Inspector to verify that the mandatory program has been completed, permitting the plant to return to service in a safe and expeditious manner. Application of this Section begins when the requirements of the construction code have been satisfied. DIVISION 1 This Division provides rules for the examination, inspection, and testing; NDE methods, qualifications, and requirements; evaluation and acceptance standards for flaws, defects, and relevant conditions; repair/replacement processes and correction actions/measures in light water cooled nuclear power plants. Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.
