SAVANNAH NUCLEAR POWER. CONTROL ROD DRIVE TESTING AND PERFORMANCE FROM PRE-CRITICAL CHECK TO 100 PERCENT FULL POWER
Precritical testing of the control rod drive system on the N.S. Savannah followed an extensive maintenance period in which the buffer seal shafts were changed, drive mechanisms removed, and minor maintenance performed on the reactor head mounted equipment. Testing and operation were conducted immediately after fuel loading and ended at 100% full power. Test objectives were (1) to prove that equipment operation was still satisfactory following maintenance and core loading operations; (2) to prove the readiness of the system immediately prior to critical reactor operation; and (3) to accumulate a log of operating experience to judge system reliability related to hydraulic system integrity. Rod positioning, freedom of rod movement, and scram were the major system functions checked. Operational experience includes system operation through two sea trials in addition to zero power and reactor power operation. The results of the test program are considered satisfactory in all aspects of manual rod control.
