| AUTOMATIC START OF AN ANNULUS EXHAUST GAS TREATMENT SYSTEM FAN DURING TRAIN  |
| RESTORATION                                                                  |
|                                                                              |
| While returning the Annulus Exhaust Gas Treatment System (AEGTS) train 'B'   |
| to standby readiness from secured status, the 'B' exhaust fan automatically  |
| started when the fan control switch was placed in the 'standby' position.    |
| The licensee believes that the initiating signal may not have been valid and |
| that the cause may have been a faulty flow switch.  Reportability is still   |
| under investigation.                                                         |
|                                                                              |
| The licensee notified the NRC Resident Inspector.                            |
|                                                                              |
| * * * UPDATE at 1047 on 01/27/99 by Fred Smith to Dick Jolliffe * * *        |
|                                                                              |
| The initiating signal for the 'B' exhaust fan could not be reproduced.       |
| Through the process of analysis and testing, licensee engineering personnel  |
| determined that the most suspect component that malfunctioned and caused the |
| initiating signal was a flow switch in the discharge of the AEGTS train 'A'. |
| A review of the data available and observations by the operating crew        |
| indicated that no actual low flow or LOCA signal existed.  Therefore, the    |
| initiation was determined to be caused by an invalid signal.                 |
|                                                                              |
| Licensee engineering personnel determined that AEGTS is considered part of   |
| the Reactor Building Ventilation System (RBVS), consistent with the UFSAR.   |
| The invalid low flow signal that was the most likely cause of the AEGTS      |
| train 'B' initiation is not considered an ESF actuation signal.              |
|                                                                              |
| The AEGTS (ESF actuation system) initiation was caused by an invalid signal  |
| that initiated the system as an RBVS and thus, the licensee desires to       |
| retract this event.                                                          |
|                                                                              |
| The licensee notified the NRC Resident Inspector.  The Operations Officer    |
| notified R3DO Tony Vegel.                                                    |

| AGREEMENT STATE REPORT - POTENTIAL OVEREXPOSURE INVOLVING A RADIOGRAPHER -   |
|                                                                              |
| ON 09/11/98, DURING AN ANNUAL INSPECTION OF CODER X-RAY AND WELDING          |
| SERVICES, McPHERSON, KS (LICENSE #21-B165-01) BY THE KANSAS DEPARTMENT OF    |
| HEALTH AND ENVIRONMENT (KANSAS INVESTIGATION FILE #KS-98-20), THE DOSIMETRY  |
| READING OF THE OWNER WAS FOUND TO BE GREATER THAN 5 REM (6400 MILLIREMS DDE) |
| FOR 1998.                                                                    |

| THE OWNER STATED THAT HE WAS ASSIGNED A DOSE OF 2370 MILLIREMS FOR THE       |
| QUARTER AND THAT HIS BADGE RECEIVED AN INADVERTENT EXPOSURE DUE TO A SPARK   |
| GENERATED WHILE HE WAS WELDING AND THAT HIS POCKET ION CHAMBER DOSE FOR THE  |
| PERIOD IN QUESTION WAS 440 MILLIREM.  HE BELIEVES THAT THE OVEREXPOSURE WAS  |
| THE RESULT OF A SPARK THAT BURNED HIS FILM HOLDER, NOT THE RESULT OF GAMMA   |
| RAYS RECEIVED DURING AN INDUSTRIAL RADIOGRAPHY OPERATION.                    |
|                                                                              |
| KANSAS INSPECTORS WERE UNABLE TO COMPLETE THEIR FOLLOWUP INVESTIGATION ON    |
| 12/10/98 BECAUSE THE LOG BOOKS IN QUESTION WERE NOT AVAILABLE AT THE TIME.   |
|                                                                              |
