| 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."                     |

| "Two sprinkler heads on system D-1 in C-337 and two sprinkler heads on       |

| "After restoration from planned maintenance, the 'A' Diesel Generator was    |
| transferred for the 'E' Diesel Generator. When the 'A' diesel Generator      |
| control was taken from local to remote, the Operator at the diesel Generator |
| heard air porting from the diesel and it began to start. This was not an     |
| expected response. Subsequently, several alarms were received in the Control |
| Room and locally and the diesel appeared to be slowing down. Seconds later   |
| it appeared the diesel began to crank up again. At this point, the Operator  |
| at the diesel initiated an emergency stop. Investigation into the cause of   |
| the auto initiation is ongoing.                                              |

| "Following extensive investigation and testing, PP&L has concluded that the  |
| unplanned roll of  the 'A' Emergency Diesel Generator (EDG) on November 18,  |
| 1999 did not constitute an unplanned Engineered Safety Feature (ESF)         |
| actuation. No EDG start signal (automatic or manual) occurred. An            |
| individual, internally mis-wired relay resulted in the energizing of a       |
| single solenoid valve, allowing cranking air to roll the engine. No other    |
| components in the complex EDG starting and control logic system circuitry    |
| were actuated. Thus, energization of the minimum actuation logic needed to   |
| fulfill the ESF function (i.e., EDG start) did not occur and the EDG ESF     |
| function was not unnecessarily challenged. The EDG would have responded      |
| properly to a start signal, had one been introduced. As such, the event      |
| reported as an unplanned ESF actuation on November 18, 1999 (NRC Event       |
| 36452) is hereby retracted."                                                 |

| Gauge, containing 8 millicuries of Cs-137 and 40 millicuries of Am-241-Be    |
| was damaged by a water truck at a construction site at Nevada State Prison,  |
| Indian Springs, NV (48 miles north of Las Vegas).  The licensee staff        |

| EMERGENCY ACTION LEVEL 9.4.1.b (RELEASE OF TOXIC OR FLAMMABLE GASES DEEMED   |

| An instrument line on a 10 Ton Carbon Dioxide tank broke off causing the     |
| tank to discharge into the 10 Ton Carbon Dioxide storage area which is       |
| located at the 84 foot level in the Auxiliary Building.  Nobody was in the   |
| area when the instrument line broke.  Personnel entered the room wearing     |
| Self-Contained Breathing Apparatus (SCBA) and isolated the leak.  Nobody was |
| injured by the incident.   Oxygen level in the 10 Ton Carbon Dioxide storage |
| area was back to normal by 0314 ET.  At this time only the access to the     |
| Diesel Fuel Oil Storage Tank Area is restricted (have to pass through the    |
| Carbon Dioxide Storage Area to get to the Diesel Fuel Oil Storage Tank       |
| Area).  The Emergency Diesel Generators are fully operable.  The Licensee is |
| investigating the incident at this time.                                     |
