| SEPARATION CRITERIA FOR REACTOR TRIP SWITCHGEAR NOT MET.                     |
|                                                                              |
| IT WAS DISCOVERED THAT BOTH TRAINS OF THE REACTOR TRIP SWITCHGEAR WERE 12"   |
| APART WHILE THE REQUIRED SEPARATION IS 20 FEET.  THIS CONDITION PUTS THE     |
| PLANT OUTSIDE ITS DESIGN BASIS AS PER 10CFR50 APPENDIX R, SEC. III.G.2.      |
| THEY HAVE STATIONED A CONTINUOUS FIRE WATCH IN THE AREA.  PLANT OPERATION    |
| WILL CONTINUE.  AS A CORRECTIVE MEASURE VARIOUS OPTIONS ARE BEING            |
| CONSIDERED, WITH ONE REQUIRING A PLANT SHUTDOWN.  THEY HAVE NOT YET          |
| DETERMINED WHICH CORRECTIVE OPTION THEY WILL IMPLEMENT.  INSTRUCTIONS HAVE   |
| BEEN GIVEN TO TRIP THE REACTOR UPON A REPORT FROM THE CONTINUOUS FIRE WATCH  |
| OF AN ACTIVE FIRE IN THE AREA THAT IS BEING MONITORED.                       |
|                                                                              |

| BASED ON ENGINEERING EVALUATION THE PLANT WAS NOT OUTSIDE ITS DESIGN BASIS   |
| WITH RESPECT TO APPENDIX "R" TO 10CFR50.  THE APPROVED FIRE PROTECTION       |
| PROGRAM ALLOWS A DIVERSE MEANS TO ACHIEVE SAFE SHUTDOWN, AS IDENTIFIED IN    |
| WCGS RESPONSE TO APPENDIX "R" SECTION III.G.  IN THIS CASE, THE DIVERSE      |
| MEANS TO ACHIEVE AND MAINTAIN SAFE SHUTDOWN USING EQUIPMENT FREE OF FIRE     |
| DAMAGE IS ACCOMPLISHED THROUGH MANUAL ROD INSERTION AS SPECIFIED IN EMG      |
| FR-S1, RESPONSE TO NUCLEAR POWER GENERATION/ATWT.  THEREFORE, THIS EVENT IS  |
| BEING RETRACTED.  R4DO (CHARLES MARSCHALL) NOTIFIED.                         |

| TECH SPEC REQUIRED SHUTDOWN DUE TO LOSS OF POWER TO STARTUP TRANSFORMERS FOR |
| APPROXIMATELY 8 MINUTES                                                      |
|                                                                              |
| The units main generator output supplies power to two (2) 230KV "A" & "B"    |
| buses.  The 230KV "A" & "B" buses, in addition to supplying power to the     |
| grid, each have a 230KV/34.5KV step-down transformer energizing the 34.5KV   |
| "A" & "B" buses, respectively.  These 34.5KV buses feed Bank 5 and 6 Startup |
| Transformers using offsite  power when the main generator is offline.  Both  |
| the "A" & "B" 34.5KV  buses deenergized for approximately 8 minutes,         |
| possibly due to a thermal overload trip condition caused by high ambient     |
| temperatures >100 degrees F (the specific location of the 34.5KV loss is     |
| under investigation).  This placed the  unit in Tech Spec 3.7.A.(3) which    |
| states "that one 230KV line must be fully operational and switchgear for     |
| both Startup Transformers to the station are energized to carry power . . .  |
| ." or the unit must be shutdown.  The unit exited the Technical              |
| Specification required Shutdown after approximately 8 minutes when both      |
| 34.5KV buses were reenergized.  The associated 4.16KV safeguard buses        |
| remained energized throughout the transient since they normally receive      |
| power from the Auxiliary Transformer during power operations. Both emergency |
| diesel generators are available, if needed.                                  |
|                                                                              |
| At the present time the licensee said that they are carrying a large amount  |
| of VARS.                                                                     |

| After further review the licensee determined that this notification was made |
| prematurely. The licensee determined that they had not begun a Technical     |
| Specification required shutdown under section 3.7.A.3, therefore, this event |
| is not reportable. Based on this information the licensee is retracting the  |
| above notification.                                                          |

| The unit automatically tripped due to the loss of all main feedwater flow    |
| after the main feedwater pump tripped on low suction pressure. All control   |
| rods inserted following the trip.  Emergency feedwater actuated as           |
| expected.                                                                    |

| The licensee reported that two main steam relief valves remained open        |
| following the trip, but reclosed after steam generator pressure was reduced  |
| to 920 psig. The unit is currently stable in Hot Standby, with steam         |

| pumps, and decay heat being relieved to the main condenser via the turbine   |
| bypass valves.                                                               |

| POST IMPLANT SURVEY OF A LOADING CART STERILE DRAPE DETECTED A RADIOACTIVE   |
| LEVEL OF 20MREM/HR..                                                         |
|                                                                              |
| Post implant survey in the operating room found radiation reading levels on  |
| the sterile drape of a cart used to hold Iodine-125 seeds which were         |
| implanted into a patients thyroid . A small piece of metal (less than 1      |
| millimeter in length)  on the carts sterile drape was found to have a        |
| radioactive level of  20mrem/hr at 3 centimeters.  The small piece of metal  |
| was placed in a lead pig and is now stored in the Hospital isotope room.     |
| All the Iodine-125 seeds that were not used for implantation in the patient  |
| were accounted for and placed in lead containers.  A bioassay will be        |
| performed on the patient within in the next few days to make sure the        |
| patient does not have any leaking iodine-125 seeds in their thyroid.         |
|                                                                              |
| This event was discovered to be reportable yesterday evening ,7/6/99, after  |
| the Radiation Safety Officer discovered that leaking seeds is considered a   |
| Medical Misadministration                                                    |

| A dumpster transporting LSA byproduct material to a disposal site developed  |
| a minor leak. The dumpster leaked  3 to 5 gallons of water containing LSA of |
| uranium byproduct material on the ground next to a roadway (highway 487      |
| about 50 miles Southwest of Carbon, Wyoming).  The area affected by the leak |
| was less than 20 square feet and cleanup of the contaminated soil is in      |
| progress.                                                                    |
