es, appropriately spiked media with known quantities of radioactivity or appropriate types of radioactive sources, should be used for the given type of radiation detection method to verify operability and/or proper calibration of radiation detectors and monitors. The following list illustrates the systems, components, and features for which the test program should demonstrate operability: 1. liquid radioactive waste handling systems; 2. gaseous radioactive waste handling systems; 3. power cycle off-gas system monitoring and controlling the presence of explosive gas mixtures (H2/O2) in gaseous waste management subsystems; 4. solid waste handling systems and resulting waste products complying with waste classification and characteristic requirements; 5. isolation features for steam generator blow down, for both the presence of radioactivity and thermal protection of demineralizer beds; 6. isolation features for condenser off-gas systems and diversion of process flow to appropriate subsystems; 7. isolation features for ventilation systems and diversion of exhaust flows to HEPA/charcoal filtration subsystems; 8. isolation features for liquid radwaste effluent systems and diversion of effluent flows to appropriate subsystems; 9. isolation features (process interlocks, backflow preventers, differential pressures, etc.) of waste processing subsystems, as equipped, in preventing the cross- contamination of nonradioactive systems and avoiding unmonitored and uncontrolled radioactive releases; 10. operability of plant process and effluent sampling systems for expected types of media; 11. testing of liquid and wet waste solidification subsystems in verifying that residual amounts of free liquid present in process packaged wastes conform with regulatory requirements and waste acceptance criteria; 12. for waste processing system supplemented with mobile skid-mounted processing equipment, as equipped, testing should include the hydraulic integrity of Appendix A to DG-1259, Page
