| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS (24-hour   |
| report)                                                                      |

| "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."                     |

| HEAD ALARM ACTUATION AT THE ERP 1A WITHDRAWAL STATION DURING A CYLINDER      |
| CONNECTION EVOLUTION.  WHILE CONNECTING THE PIGTAIL TO THE CYLINDER, A       |
| SLIGHT WISP OF UF6 SMOKE APPEARED BETWEEN THE PIGTAIL AND THE MANIFOLD       |
| SAFETY VALVE.  EMERGENCY RESPONSE PERSONNEL RESPONDED AND MONITORED THE      |

| 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.                      |

| -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.                       |
|                                                                              |
