d rod worth minimizers. c. Demonstrate proper operation of rod position instrumentation and proper interaction of the control rod drive system with other systems and design features, such as automatic reactor power control systems and refueling equipment. d. Demonstrate proper operation, including the correct failure mode on loss of power, for the control rod drive system and proper operation of system alarms. 2. Chemical Control System Tests (PWR Only): a. Verify proper blending of boron solution and water; uniform mixing; adequacy of sampling and analytical techniques; operation of heaters and heat tracing; and operation of instrumentation, controls, interlocks, and alarms. b. Demonstrate by test the proper rate of emergency boron injection into the reactor coolant system and the rate of dilution from the primary system. 1 Regulatory Guide 1.20, “Comprehensive Vibration Assessment Program for Reactor Internals during Preoperational and Initial Startup Testing,” (Ref. 14) should be used as guidance for vibration monitoring of reactor internals and other components. Appendix A to DG-1259, Page A-4 c. Verify the redundancy, electrical independence, and operability of system components. Demonstrate the correct failure mode on loss of power to system components. 3. Standby Liquid Control System (SLCS) Tests. a. Demonstrate proper operation of the system with demineralized water in the system flow paths and discharge. b. Verify the proper boron enrichment, flow rates, tank volume and concentration of neutron absorber solution before entry into the technical specification (TS) mode when SLCS operability is required. c. Demonstrate the operability of instrumentation, controls, interlocks, alarms, and equipment protective devices in valve controls. d. Verify the operability of electrical room heaters, air spargers, and/or heat tracing. e. Verify proper operation of the SLCS nitrogen pressurization system, if provided. f. Conduct test firings of squib-actuated valves
