e effects of natural phenomena combined with those of normal and accident conditions without loss of capability to perform their safety function. Load combinations and specifications cited in this SRP section provide acceptable engineering criteria to accomplish that function. Meeting these requirements provides added assurance that safety-related structures will be designed to withstand the effects of natural phenomena and will perform their intended safety function. 4. Compliance with GDC 4 requires that nuclear power plant SSCs important to safety be designed to accommodate the effects of and be compatible with environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including LOCAs, and be appropriately protected against dynamic effects, including the effects of missiles, pipe whipping, and discharging fluids, that may result from equipment failures and from events and conditions outside the nuclear power unit. This SRP section provides methods acceptable to the staff to assure compliance with GDC 4. The methods include load combinations, acceptance criteria, standards, and codes. Meeting this requirement provides assurance that structures other than containment will withstand loads from internal events, such as those described above, and from external sources such as explosive hazards in proximity to the site, potential aircraft crashes (nonterrorism-related incidents), and missiles generated from activities of nearby military installations or turbine failures, thus decreasing the probability that these events would damage structures other than containment and cause release of radioactive material. Meeting these requirements provided added assurance that structures will not fail in function as designed, thus providing protection against lost of their structural integrity. 5. Compliance with GDC 5 prohibits the sharing of structures important to safety among nuclear power units unless it can be shown that such
