5.2.2(Cont'd)
(1)
It is determined by the investigation that any mal-function which has occurred neither impairs the ability to control the reactor nor indicates the imminent im-pairment of the performance of additional components of the control rod system.
(2) The operating hydraulic water to the defective control rod has been tagged and valved out to prevent withdrawal of the control rod after an attempt has been made to in-sert the control rod.
(3) The core shutdown margin requirement'(described in (b) above) can be met with the remaining operable control rods.
Evaluation of this requirement shall be based on previous experimental measurements.
(g) Minimum Accuracy of Rod Position Indicating System - The control rod drive positions itself in 23 discrete positions over its travel.
The position indicating system is of a digital readout design and indicates the drive position over a range of 1.5 inches for each position of the drive.
Control rods shall not be allowed to remain in position where the indication is not operable.
If all indication for a partic-ular control rod is lost, the rod shall'not be moved until the indication has been restored, except for scram.
(h) Operation of the Scram Dump Tank Valves and High Level Alarm The scram dump tank air operated vent and drain valves shall be (1) verified open at least once per 31 days, and (2) cycled through at least one complete cycle of full travel once per quarter. These valves may be closed inter-mittently for testing under administrative controls. At every refueling outage, the valves shall be tested to close within 20 seconds of receipt of a scram signal and the scram dump tank high level alarm shall be verified operable at a level of 10 + 1/2 inch below the tank centerline.- An unexplained high Tevel alarm shall require immediate investi-l gation and if not corrected, subsequent insertion of all or all but one control rod drive within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
