cent, 100 percent). r. Calibrate, as necessary, and verify the performance of major or principal plant control systems including: 1. T-average controller; 2. automatic reactor control system; 3. boron addition systems (PWR); 4. integrated control system; 5. pressurizer control system; 6. reactor coolant flow control system; main, auxiliary, and emergency feedwater control systems; 7. hotwell level control systems; 8. steam pressure control systems; and 9. reactor coolant makeup and letdown control systems (25 percent, 50 percent, 75 percent, 100 percent). s. If not previously accomplished, verify, as appropriate, the operability, response times, relieving capacities, set points, and reset pressures for: 1. pressurizer relief valves; 2. main steam-line relief valves; 3. atmospheric steam dump valves; 4. turbine bypass valves; and 5. turbine stop, intercept, and control valves (25 percent). t. During transient tests, verify the operability, set points, and reset pressures of relief valves (25 percent). Appendix A to DG-1259, Page A-27 u. Verify the operability and response times of main and branch steam-line isolation valves. For PWRs, licensees may submit justification for conducting this test at low power and/or a description of design qualification tests for valves of the same size and design (25 percent). v. Verify that the main steam and feedwater systems operate in accordance with design performance requirements. In addition, verify that acoustic resonance criteria are not reached in the main steam system as power level is increased (25 percent, 50 percent, 75 percent, 100 percent). w. Demonstrate adequate beginning of life performance margins for shielding and penetration cooling systems to provide assurance that they will be capable of maintaining temperatures of cooled components within design limits with the minimum design capability of cooling system components available (100 percent). x. Demonstrate adequate beginning of life performance margins for
