e control systems) 8. seal water systems 9. vent and drain systems (for contaminated or potentially contaminated systems and areas), and drain and pumping systems serving essential areas (e.g., spaces housing diesel generators, essential electrical equipment, and essential pumps) 10. purification and cleanup systems for the reactor coolant system 11. compressed gas system15 supplying pneumatic equipment, components, or instrumentation that are required to function to support the normal operation of the facility or are essential for the operation of standby safety equipment or engineered safety features. Compressed gas systems may also be relied upon for breathing air; therefore, this system should be tested for air load transients that can affect both plant safety and personnel safety. 12. boron recovery system 13. communication systems 14. heating, cooling, and ventilation systems serving the following areas should meet the guidance in RG 1.140: a. spaces housing engineered safety features; b. primary containment; c. battery rooms; 15 Regulatory Guide 1.68.3, “Preoperational Testing of Instrument and Control Air Systems,” (Ref. 31) provides detailed guidance on testing of instrument and control air systems. Appendix A to DG-1259, Page A-19 d. diesel generator buildings; e. auxiliary, reactor, turbine, and radioactive waste handling buildings; f. control room habitability systems; g. ultimate heat sink pump house; and h. fuel storage and handling area ventilation system. 15. shield cooling systems 16. cooling and heating systems for the refueling water storage tank (PWR) and suppression pool cooling and heating for the condensate storage tank (BWR) 17. equipment and controls for establishing and maintaining subatmospheric pressures in sub-atmospheric containments 18. heat tracing for freeze protection 19. emergency lighting for safe egress, post accident vital areas, and emergency facilities 20. cathodic protection system for corrosion control of underground and
