ted so as to have an extremely low probability of abnormal leakage, of rapidly propagating failure, and of gross rupture. • ARDC-30 indicates that the components that are part of the reactor coolant boundary shall be tested to the highest quality standards practical. • ARDC-32 provides that the components that are part of the reactor coolant boundary shall be designed to permit periodic inspection and functional testing of important areas and features to assess their structural and leaktight integrity. • ARDC-36 indicates that a system that provides emergency core cooling shall be designed to permit appropriate periodic inspection of important components to ensure the integrity and capability of the system. 1 The regulations in 10 CFR 50.55a require that systems and components of boiling- and pressurized-water-cooled nuclear power reactors meet the requirements for PSI and ISI in ASME Code, Section XI, Division 1, “Rules for Inspection and Testing of Components of Light-Water-Cooled Plants” (Ref. 10). 2 While the GDCs establish minimum requirements for the PDC for water-cooled nuclear power plants similar in design and location to plants for which construction permits have been issued by the Commission, the GDCs are also considered to be generally applicable to other types of nuclear power units and are intended to provide guidance in establishing the PDC for such other units. DG-1383, Page 5 • ARDC-39 states that the containment heat removal system shall be designed to permit appropriate periodic inspection of important components to ensure the integrity and capability of the system. • ARDC-42 provides that the containment atmosphere cleanup systems shall be designed to permit appropriate periodic inspection of important components, such as filter frames, ducts, and piping, to assure the integrity and capability of the systems. • ARDC-45 indicates that the structural and equipment cooling systems shall be designed to permit appropriate periodic
