Abstract:
The proposed standard covers the proper design and construction of concrete structures which form part of a nuclear plant and which have nuclear safety related functions, but does not cover concrete reactor vessels and concrete containment structures (as defined by AC1 Committee 359). The structures cqvered by the proposed code include concrete structures inside and outside the contamment system. Appendix A, Thermal Considerations, pro p osed as an addition to the standard, presents minimum requirements for members subjected to time-dependent and position-dependent temperature variations occurring during normal operation and accident conditions, However, it does not address temperature and shrinkage reinforcement or temperature requirements during curing. The proposed Appendix C presents special provisions for design of structural elements subjected to time-dependent loads due to coIIision of masses (impact) and time-dependent loads not associated with the collision of solid masses (impulse).
