assification of fire protection systems. Application of this guidance ensures that (1) the fire protection systems for manual firefighting in areas containing safety related equipment, (2) containment penetrations and (3) RCP lube oil will be properly classified and analyzed for safe-shutdown earthquake loads. Compliance with the above requirements and guidance assures that the SSCs important to safety that are required to function during an SSE are properly classified as Seismic Category I and will function during such events enabling accomplishment of the safety functions described above. 3. Compliance with GDC 61 requires that radioactive waste management systems, and other systems that may contain radioactivity, be designed to assure adequate safety under normal and postulated accident conditions. Postulated conditions considered with respect to seismic design and classification of SSCs include losses of SSC integrity and potential radioactive releases as a result of seismic events. RG 1.143 provides acceptable methods and guidance relative to seismic design and classification for radioactive waste management SSCs. This RG provides classification information and design criteria to assure that components and structures used in radioactive waste management systems are designed, constructed, installed and tested in a manner that protects the health and safety of the public and the plant operating personnel. Designing and constructing the radioactive waste management SSCs to meet the requirements of GDC 61 and the guidance on seismic design and classification contained in RG 1.143 provides assurance that SSCs containing radioactivity will be properly classified and radiation exposures as a result of seismic events will be as low as reasonably achievable. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria.
