nts to be evaluated as part of construction permit (CP), OL, combined license (COL), or early site permit reviews or for site parameter envelopes in the case of design certifications, thereby ensuring that components 3.8.1-17 DRAFT Rev. 2 - April 1996 important to safety will function in a manner that will maintain the plant in a safe condition. Meeting this requirement provides assurance that the containment will be designed to withstand the effects of natural phenomena without loss of capability to perform its intended function. 3. Compliance with GDC 4 requires that nuclear power plant structures, systems, and components 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. SRP Section 3.8.1 cites acceptance criteria, standards, and codes so that concrete containments will resist dynamic effects, including missiles and pipe whipping, discharging fluids, and other events, including LOCA effects. Meeting this requirement provides assurance that the containment will withstand dynamic effects such as missiles impacts associated with tornadoes or other external sources, including aircraft, thus decreasing the probability that these events would cause damage to the containment that could result in release of radioactive material. 4. Compliance with GDC 16 requires that a reactor containment and its associated systems be provided to establish an essentially leaktight barrier against uncontrolled release of radioactivity to the environment and to ensure that design conditions important to safety are not exceeded for as long as required for postulated accident conditions. GDC 16 applies to this SRP section because a typical concrete containment has a liner plate on the inside face of the containment structure that forms a leaktight barrier. To serve as a leaktight barrier, the liner plate is designed as a Category I
