| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS (24-hour |
| report) |
| |
| The following text is a portion of a facsimile received from Paducah: |
| |
| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question. Subsequently, these |
| sprinkler systems were declared inoperable, and TSR-required actions |
| establishing roving fire patrols were initiated. This deficiency was |
| detected during scheduled system inspections conducted by Fire Protection |
| personnel. Currently, functionality of the sprinkler heads has not been |
| fully evaluated by Fire Protection personnel, and the remaining cascade |
| buildings are currently being inspected, and if necessary, this report will |
| be updated to identify any additional areas. It has been determined that |
| this event is reportable under 10CFR76.120(c)(2) as an event in which |
| equipment is disabled or fails to function as designed." |

| * * * UPDATE AT 1600 ON 12/09/99 BY ERIC SPATH TO JOLLIFFE * * * |
| |
| PORTSMOUTH PERSONNEL DESIRE TO RETRACT THIS EVENT BASED ON THE DETERMINATION |
| THAT THE ACTUAL PLANT CONDITIONS WHICH THE SAFETY SYSTEM IS DESIGNED TO |
| PROTECT AGAINST DID NOT EXIST. THE 1A WITHDRAWAL POSITION PIGTAIL WAS |
| ISOLATED FROM THE LIQUID UF6 SYSTEM BY A CLOSED MANIFOLD VALVE AND NO LIQUID |
| UF6 WAS INVOLVED IN THE OUT GASSING. A WITHDRAWAL WAS TAKING PLACE AT THE |
| ADJACENT 1B POSITION, WHICH SHARES THE SAME COMPRESSORS, PIPING, AND |
| ACCUMULATOR, BUT THE LEAK WAS NOT ASSOCIATED WITH THIS POSITION. THE TECH |
| SPEC REQUIREMENT BASIS STATEMENT INDICATES THAT THE PURPOSE OF THE PIGTAIL |
| LINE ISOLATION SYSTEM IS TO MINIMIZE A RELEASE OF LIQUID UF6 DUE TO A |
| PIGTAIL FAILURE DURING A WITHDRAWAL. SINCE THE PIGTAIL WAS ISOLATED FROM |
| THE LIQUID UF6 SYSTEM WHILE THE CYLINDER WAS BEING CONNECTED, THE PIGTAIL |
| LINE ISOLATION SYSTEM SAFETY FUNCTION WAS NOT REQUIRED. |
| |
| PORTSMOUTH PERSONNEL NOTIFIED THE NRC RESIDENT INSPECTOR. THE NRC |
| OPERATIONS OFFICER NOTIFIED THE R3DO PAT HILAND AND THE NMSS EO TED SHERR. |

| -TECH SPEC REQD PLANT SHUTDOWN DUE TO INCORRECT FLOW BIASED APRM SCRAM |
| SETPOINTS- |
| |
| Engineering analysis based on in-situ plant data identified a discrepancy in |
| the 100% drive flow value used to develop the flow biased APRM scram |
| setpoints specified in the core operating limits report. The discrepancy is |
| such that the flow biased scram line on the power-to-flow map has a greater |
| slope than specified in the core operating limits report. This condition |
| results in a non-conservative APRM scram setpoint at lower core flows. The |
| APRM scram function (Tech Spec Table 3.1-1) is considered inoperable until |
| this condition can be corrected. Tech Specs require that all operable |
| control rods be inserted within 4 hours or reduce power to IRM range and |
| place the mode switch in startup within 8 hours. New APRM gain values are |
| being established which will correct this discrepancy. |
| |
| The licensee notified the NRC Resident Inspector. |
