The criteria contained in this standard establish minimum functional and design requirements for safety systems for nuclear power generating stations. The safety systemis the collectionof systems required to minimize the probability and magnitude of release of radioactive material to the environment by maintaining plant conditions within the allowable limits established for each design basis event. Safety system functional and design criteria are also contained in other standards.1 Illustration. Fig1 illustrates the scope of the safety system. Application The safety system criteria established herein are to be applied to those systems required to protect the public health and safety by functioning to mitigate the consequences of design basis events. However@ this standard does not necessarily apply to all of the safety related systems@ structures@ and equipment required for complete plant safety. The criteria herein are directed to the power@ instrumentation@ and control portions of the safety system. To safety these criteria@ interface requirements may be imposed on the other portions of the system. 1 Refer to Refs [B1]@ [B2]@ [B1]@ [C1]@ [C2]@ [C3]@ [C4]@ [C8]@ [C9]@ and [C10] in Appendixes Band C.
