| LOSS OF RESERVE STATION TRANSFORMER CAUSED LOSS OF REACTOR COOLANT PUMP |
| WHICH REQUIRED A REACTOR TRIP |
| |
| The 'C' reserve station transformer (RST) deenergized which resulted in a |
| loss of the Unit 2 'C' reactor coolant pump (RCP). The Unit 2 loss of RCP |
| 'C' required a reactor trip, which was initiated manually, all rods fully |
| inserted and the plant is stable in Hot Standby. Unit 2 was on the steam |
| dumps to the condenser and main feedwater at the time of the trip and |
| continue on them. |
| |
| Unit 1 '1H' emergency bus was lost due to the problem with the 'C' RST and |
| the failure of the '1H' emergency diesel generator (EDG) to start. The loss |
| of the '1H' bus caused the loss of the 'C' RCP and 'A' Residual Heat Removal |
| (RHR) pump, which led to the loss of core cooling circulation, but was |
| restored in less than 2 minutes by starting the 'B' RHR pump. |
| |
| The 'C' RST and the '1H' EDG problems are being investigated, the cause of |
| the problems are unknown at this time. Unit 2 will remain in Hot Standby |
| until all problems are corrected. |
| |
| The licensee informed the NRC Resident Inspector. |
| |
| * * * UPDATE AT 1503 EDT ON 4/5/00 BY JIM CROSSMAN TO FANGIE JONES * * * |
| |
| The licensee made a correction to the reporting criteria. Removed the |
| original criteria of 10 CFR 50.72(b)(1)(ii) Degraded Condition During |
| Operation, this was for Unit 1 which was shutdown at the time. Added the |
| criteria 10 CFR 50.72(b)(2)(ii) ESF Actuation, due to a real start signal to |
| two of the emergency diesel generators. |
| |
| The licensee notified the NRC Resident Inspector. Notified R2DO (Steve |
| Cahill). |

| TWO CONTAINMENT ISOLATION VALVES CLOSED DUE TO BLOWN FUSES |
| |
| The Nuclear Safety and Compliance Group notified Operations today that a |
| report of ESF activation should be made to the NRC. The group noted that |
| during the review of a logic system functional testing on diesel generator |
| 2R43-S001A, a logic power fuse (2A71-F21A) blew closing two primary |
| containment isolation valves (2G11-F003 & 2G11-F019). These valves are the |
| inboard drywell sump isolation valves. This occurred on 4/2/00 at 0030 |
| EDT. |
| |
| The system was checked, fuses replaced, and the valves opened. The valves |
| are fully operational. |
| |
| The licensee notified the NRC Resident Inspector. |

| 500 mCi STRONTIUM/YTTRIUM SOURCE LOST TO LANDFILL |
| |
| A generally licensed strontium/yttrium source, 500 mCi, from an 'In Flight |
| Blade Inspection System' (IFBIS) was improperly placed in a dumpster which |
| in turn was dumped at a regular land fill. The U.S. Navy is investigating |
| the incident and trying to determine where and how deep the source is in the |
| land fill. |
| |
| The U.S. Navy notified NRC Region 2 (M. Fuller) and intends to notify the |
| State of Arizona. |
