intended safety function and provide assurance to the public that offsite radiation doses will be ALARA.35 5. 10 CFR 50.46 requires that each boiling and pressurized light-water nuclear power reactor fueled with uranium oxide pellets within Zircaloy cladding must be provided with an emergency core cooling system (ECCS) that must be designed such that its calculated cooling performance following postulated loss-of-coolant accidents conforms to the specified criteria regarding the peak cladding temperature, maximum cladding oxidation, maximum hydrogen generation, coolable geometry, and long-term cooling. 10 CFR 50.46 is applicable to SRP 6.2.5 because peak cladding temperature, maximum cladding oxidation, maximum hydrogen generation, coolable geometry, and long-term cooling depends on the effectiveness of emergency cooling systems following postulated loss-of-coolant accidents. Therefore, the ECCS is an essential element of the safety features of a nuclear power plant. DRAFT Rev. 3 - April 1996 6.2.5-10 Meeting these requirements provides additional assurance the reactor can be safely shut down and cooled without undue risk to the health and safety of the public following postulated LOCA.36 III. REVIEW PROCEDURES The procedures described below provide guidance for the detailed review of the combustible gas control systems. The reviewer selects and emphasizes material from this SRP section, as may be appropriate for a particular case. Portions of the review may be done on a generic basis for aspects of combustible gas control systems design common to a class of plants or by adopting the results of previous reviews of similar plants. Upon request from the primary reviewer, other review branches will provide input for the areas of review stated in subsection I, above. The primary reviewer obtains and uses such input as required to assureensure that this review procedure is complete. The combustible gas control systems include systems for mixing the combustible gases,
