Specify in Abstract below or in ANALYSIS OF SAFETY SIGNIFICANCE The plant responded as expected to the automatic reactor trip. Although one control rod indication remained at 18 steps, the control rod was subsequently verified to be fully inserted and the rod position indicator was appropriately adjusted.
CORRECTIVE ACTIONS
Immediate Corrective Actions:
0 Replace GSU Transformer Surge Arresters (all phases) 0 Replace 230kV Stand Off Insulators (all phases) 0 Replace High Voltage (HV) Bushings (all phases) with longer bushings 0
Replace conductors between 230kV string bus and GSU HV bushings (jumpers)
Internal inspection of the GSU transformer 0
Generator Radial Lead Seals were replaced Corrective Actions to Prevent Recurrence:
- 1. Implement long term action plan for the Unit 3 and 4 Circulating Water System to mitigate degradation issues that lead to canal water carry over. Action plan to improve the following:
o Silencer condition and performance o
Moisture separator (3/4T34) drain line operation o
Water box vacuum tank check valves operation o
Vacuum air leaks.
- 2. Replaced Unit 3 GSU Transformer High Voltage Bushings (all phases) with longer bushings.
(Complete)
- 3. Replace Unit 4 GSU Transformer High Voltage Bushings (all phases) with longer bushings.
Contributing Cause Corrective Actions:
- 1. Unclogged moisture separator drain loop seal. (Complete)
- 2. Replaced the silencer of the Circulating Water Condenser Water Box Priming System Ejector.
(Complete)
- 3. Replaced all four condenser water box vacuum tank check valves (Complete)
ADDITIONAL INFORMATION
EIIS Codes are shown in the format [IEEE system identifier, component function identifier, second component function identifier (if appropriate)].
