Radioactivity monitors and conductivity monitors located in the system discharge lines are acceptable means for implementing this requirement. 4. Descriptive information, drawings, and system analyses are reviewed to ensure that essential portions of the system will function following design-basis accidents, assuming a concurrent single active component failure. The reviewer evaluates failure mode and effects analyses presented in the SAR to ensure the function of required components, 9.1.3-11 Revision 2 - March 2007 trace the availability of these components on system drawings, and check that minimum system flow, makeup, and heat transfer requirements are met for each degraded situation over the required time spans. For each case, the design will be acceptable if alarms are provided to notify operators of the degraded condition and essential functions can credibly be restored. 5. The spent fuel pool cleanup system and various auxiliary systems are designated as nonsafety-related systems and are designed accordingly (nonseismic Category I). The reviewer evaluates these systems to ensure that their failure cannot affect the functional performance of any safety-related system or component. The relationship and proximity between the nonsafety-related system and safety-related systems or components are determined by reviewing the integrated structure and component layout diagrams. Independent analyses, engineering judgment, and comparisons with previously approved systems are used to verify that where a nonsafety-related system interconnects or interfaces with the cooling system, its failure by any event or malfunction will not preclude adequate functional performance of the cooling system. 6. The staff also reviews the cleanup system to ensure that it has been designed with the capability to maintain acceptable pool water conditions. The staff reviews the descriptive information and drawings provided in the application to verify the following: A. The secondary reviewer
