nd other applicable codes used to define allowable stresses in threaded fasteners. Loads are determined in the design of the components in which the threaded fasteners are installed, which in turn are designed in accordance with ASME, AISC, or other appropriate standards to withstand the effects associated with normal operation, maintenance, testing, and postulated accidents, including LOCAs. Meeting the requirements of GDC 4 provides assurance that fasteners important to safety are designed to resist the loads and conditions associated with normal operation, maintenance, testing, and postulated accidents, thereby performing their intended functions so that SSCs containing these fasteners are capable of performing their intended safety functions.37 6. The requirements of GDC 14 that are applicable to systems and components containing threaded fasteners are described in subsection I.B.6. Threaded fasteners in the RCPB are to be designed, fabricated, and tested in accordance with Section NB of the ASME Code, which includes stringent requirements to ensure a low probability of failure or gross rupture of RCPB components. Meeting the requirements of GDC 14 provides assurance that fasteners used in components of the RCPB will perform their intended function so that the RCPB is capable of remaining intact and preventing the spread of radioactive material.38 7. The requirements of GDC 15 that are applicable to systems and components containing threaded fasteners are described in subsection I.B.7. Threaded fasteners in the RCS are to be designed, fabricated, and tested in accordance with Section NB of the ASME Code, which includes stringent requirements to ensure that the design conditions in fasteners used in the RCS are not exceeded during normal operation, including anticipated operational occurrences. 3.13-19 DRAFT Rev. 0 - April 1996 Meeting the requirements of GDC 15 provides assurance that fasteners used in components of the RCS will perform their intended function
