| THREE CABLE TRAYS FOUND IN REACTOR BUILDING DO NOT MEET SEPARATION           |
| CRITERIA.                                                                    |

| The licensee discovered three cable trays in the reactor building that do    |
| not meet the design criteria for separation of trains.  The discovery was    |
| during a walkdown of cable trays in the plant following review of similar    |
| events in the industry.                                                      |
|                                                                              |
| Corrective action will be to install fire barrier material between the       |
| division 1 and 2 cable trays.  The design for the barriers has been started, |
| and the actual work is expected to be complete within 2 weeks.  It has been  |
| determined that interim measures, such as a fire watch, are not necessary    |
| because the cable trays carry only low amperage instrument and control       |
| cables and because they are fused.                                           |
|                                                                              |

| 13,000 GALLONS OF RESTORATION WATER SPILLED CONTAINING 1.4 PPM U3O8.         |

| This report is made in compliance with a license requirement to report any   |
| spill greater than 10,000 gallons.  This is in mine unit #9 which is located |
| about 90 miles northeast of Casper, WY.  The spill is from an underground    |
| water trunk line and is estimated at approximately 13,000 gallons.  The      |
| water contains 1.2 ppm uranium or 1.4 ppm U3O8; the drinking water limit is  |
| 5 ppm uranium.  This spill has no threat or adverse impact to the public or  |
| the environment.  The nearest habitation is about 4 miles away, and the      |
| nearest town is about 15 miles away.  The water is part of the restoration   |
| of ground water program.  Flow through the trunk line has been secured.      |
|                                                                              |
| Recovery of the water is not likely as there is between 2 and 3 feet of snow |
| on the ground.                                                               |

|                                                                              |

|                                                                              |
| "At 1340 CST on 4-3-99, during troubleshooting activities on a Criticality   |
| Accident Alarm System (CAAS) Cluster Trouble alarm on C-710 Cluster AQ,      |
| 48-VDC breakers RA-5 and RA-7 tripped.  The troubleshooting activities were  |
| being performed under an approved Maintenance Work Package at the time the   |
| breakers tripped.  As a result of the breakers tripping, control power was   |
| lost to the C-333, C-333A, C-337, C-360, C-710, C-720, and C-746Q CAAS       |
| building horns and lights, thus losing audibility of the CAAS systems.       |
| C-710 CAAS system was inoperable at the time of the trip, but the other      |
| facilities CAAS systems were required to be available and operable.  The     |
| loss of the 48 VDC was annunciated on a CAAS alarm panel in C-300 and was    |
| immediately investigated.  On discovery of the two breakers being tripped,   |
| the breakers were reclosed.  The 48-VDC power was off for approximately 2    |
| minutes.                                                                     |
|                                                                              |
| "The inaudibility of the CAAS systems is reportable as a 24-hour event       |
| report per 10CFR76.120(c)(2).                                                |
|                                                                              |
| "The NRC resident inspector has been notified of this event."                |
