| THE PLANT DOES NOT MEET THE DESIGN BASIS REQUIREMENT FOR RHR HEAT EXCHANGER |
| CONTROL VALVES TO BE SECURED IN A SAFE POSITION. |
| |
| DURING A REVIEW OF THE OPERATING PROCEDURES FOR THE RESIDUAL HEAT |
| REMOVAL(RHR) HEAT EXCHANGER SYSTEM, NO STEPS OR LINEUPS WERE FOUND TO |
| IMPLEMENT THE DESIGN BASIS REQUIREMENT FOR THE RHR HEAT EXCHANGER FLOW AND |
| BYPASS CONTROL VALVES TO BE SECURED IN THEIR SAFE POSITION. |
| |
| THE RHR HEAT EXCHANGER FLOW AND BYPASS CONTROL VALVES WERE FOUND TO BE |
| CONFIGURED WITH THE SOLENOID VENT VALVES IN AN ENERGIZED CONDITION, |
| THEREFORE POTENTIALLY ALLOWING THE NON-SAFETY RELATED POSITIONER TO CONTROL |
| THE VALVE. |
| FAILURE OF ONE OF THE NON-SAFETY POSITIONERS (DUE TO ADVERSE CONDITIONS) |
| COULD HAVE DRIVEN THE VALVES TO THEIR NON-SAFETY POSITION AT THE ONSET OF |
| A POSTULATED ACCIDENT, THEREBY PREVENTING THE IMMEDIATE AVAILABILITY OF THE |
| LOW HEAD SAFETY INJECTION FLOW. |
| |
| THIS CONDITION WAS RESOLVED AS SOON AS IT WAS IDENTIFIED BY DE-ENERGIZING |
| AND REMOVING THE FUSES FOR THE VALVES. |
| |
| THE RESIDENT INSPECTOR WAS NOTIFIED. |
