| THE PLANT HAD AN RPS ACTUATION ON A LOW LEVEL STEAM GENERATOR SIGNAL.        |
|                                                                              |
| The plant had a reactor protection signal actuation due to an actual low     |
| level steam generator trip signal.  The reactor was already shut down with   |
| all rods fully inserted, so there was no affect on the reactor from this     |
| actuation.  The steam generator level was restored to above the low level    |
| trip setpoint.  The cause of the low steam generator level appears to be due |
| to inadequate procedures, but they are still investigating.                  |
|                                                                              |

| "A valid low steam generator lever signal was processed through the Reactor  |
| Protection System (RPS) coincident logic.  This signal was not expected      |
| because steam generator level was being maintained by control room personnel |
| within the band required/allowed by the applicable procedure.  At the time   |
| of the trip signal, the reactor was in Mode 3 with the Trip Circuit Breakers |
| (TCB) open.  At the time the ESF signal was generated, a normal reactor      |
| shutdown had been completed (entry into Mode 3), control rods had been       |
| inserted, and steam generator level was being maintained within a specified  |
| range as required by the applicable procedure."                              |
|                                                                              |
| "Reportability"                                                              |
|                                                                              |
| "For the steam generator level trip event, an ESF was not needed to mitigate |
| the consequences of an event, and an ESF did not actuate as a result of the  |
| trip signal.  A normal reactor shutdown had been completed (entry into Mode  |
| 3), control rods had previously been inserted, and steam generator level was |
| being maintained within a specified range as required by the applicable      |
| procedure.  For the MP2 steam generator trip event, the consequences of an   |
| event were not mitigated, and an ESF component did not actuate.  Therefore,  |
| since an ESF signal did not process to an ESF component (TCBs were open), an |
| actuation did not occur, and an event did not exist which required           |
| mitigation; this report is being retracted."                                 |
|                                                                              |

| At 1000 on 09/29/99, the radiation safety officer was notified of a          |
| potential medical misadministration at Womack Army Medical Center located at |
| Fort Bragg in North Carolina.  The following information was provided:       |
|                                                                              |
| At 1100 on 09/28/99, a patient was scheduled to received 2 mCi of I-131 as   |
| part of a yearly whole body scan.  (The patient had a history of thyroid     |
| cancer, and the patient's thyroid had previously been removed.)  At 1105, a  |
| technician measured a dose of 2.76 mCi of I-131.  The technician then made a |
| revision to the dose on the paperwork and administered the dose prior to     |
| obtaining the authorized user's approval of the change Apparently, the       |
| technician assumed that the authorized user would approve the change.  The   |
| authorized user subsequently signed the paperwork (after the dose was        |
| administered).                                                               |
|                                                                              |
| This was in violation of the licensee's Quality Management Program which     |
| requires the authorized user to approve (either verbally or in writing) dose |
| revisions prior to administration.   The licensee stated that the authorized |
| user's verbal approval of a dose revision can be given prior to the          |
| administration if the authorized user is not physically available to sign an |
| approval prior to performance of an administration involving a dose          |
| revision.  In that case, the paperwork can be signed by the authorized user  |
| after the administration.                                                    |
|                                                                              |
| The licensee stated that adverse health effects are not expected as a result |
| of this event.  At the time of this event notification, it was not known     |
| whether or not the patient and/or attending physician had been notified of   |
| the potential medical misadministration.                                     |
|                                                                              |
| The licensee notified the NRC Region 2 office (Hector Bermudez).             |
|                                                                              |

| "Non-radiological treated water was released to the environment via a        |
| pathway not specified in the NPDES permit.  [The] State of Ohio              |
| Environmental Protection Agency was notified."                               |
|                                                                              |
| The licensee stated that raw water from the lake is treated with a           |
| coagulator and gravity filter before being stored in a clearwell.  The water |
| in the clearwell is then used as seal water for the circulating water pumps  |
| and service water pumps.  The clearwell overflows to the storm drains, and   |
| various released of this treated water has occurred over the life of the     |
| plant.  The NPDES permit does not allow treated water to be released via the |
| storm drain system.                                                          |
|                                                                              |
| Operators recently received training of the NPDES permit requirements        |
| following a previous valve failure that resulted in a release of chlorinated |
| water to a storm drain on 08/17/99.  (Refer to event #36037 for additional   |
| information.)  As a result of this heightened awareness, an operator         |
| performing rounds questioned the clearwell overflow release path, and it was |
| discovered that pathway was not in accordance with the NPDES permit.         |
|                                                                              |

| "At 1049 [hours] on 09/29/99, the South Plant Vent (SPV) Radiation           |
| Monitoring Skid (RMS) was removed from service for a scheduled radiation     |
| protection surveillance.  Following completion of this surveillance, the     |
| skid was returned to service at 1127 [hours].  At 1133 [hours], the SPV RMS  |
| skid began giving erratic indications including high effluent radiation,     |
| high particulate activity, and high noble gas activity.  Radiological        |
| surveys of the plant vent stack and other associated areas revealed no       |

| Compensatory measures have been initiated [in accordance with] plant         |

| UNUSUAL EVENT DECLARED DUE TO A FREON LEAK FROM A CONTROL ROOM CHILLER INTO  |
| THE AUXILIARY BUILDING                                                       |
|                                                                              |
| The licensee declared the unusual event at 2133 on 09/29/99 due to a release |
| of toxic gas (a Freon leak) deemed to be detrimental to safe operation of    |
| the plant.  No radiological release is in progress.  The 33' wind direction  |
| is from 146 at 17.9 miles per hour.  There were no protective actions       |
| recommended.                                                                 |
|                                                                              |
| At 2117 hours on 09/29/99, the 'B' control room ventilation train chiller    |
| tripped resulting in an automatic start of the 'A' control room ventilation  |
| train.  The trip was the direct result of a major freon leak dispersing into |
| the auxiliary building.  All non-essential personnel were evacuated from the |
| auxiliary building.  An Unusual Event was declared at 2133 hours on 09/29/99 |
| in accordance with Emergency Classification Guidance Section 9.4.1.B,        |
| release of toxic gas deemed detrimental to safe operation of the plant.  No  |
| personnel injuries have occurred, and all access to the auxiliary building   |
| is being controlled until follow-up actions are complete.                    |
|                                                                              |
| The 'A' control room vent train is currently in service.  There is no        |
| indication of any freon in the control room, and the control room was not    |
| placed on recirculation.                                                     |
|                                                                              |
| The licensee plans to terminate the Unusual Event when the freon leak is     |
| isolated and when air levels in the auxiliary building are restored to       |
| normal.                                                                      |
|                                                                              |
| The licensee stated that the emergency response data system (ERDS) has not   |
| been activated because ERDS is down for the performance of Y2K upgrades.     |
|                                                                              |
| The licensee notified the NRC resident inspector, the states of Delaware and |
| New Jersey, and the Lower Alloways Creek Township.                           |
|                                                                              |

| The leak was terminated because the full freon charge in the chiller         |
| dispersed (2,200 pounds), and the atmosphere in the auxiliary building has   |
| been restored to normal.  As a result, the licensee terminated the Unusual   |
| Event at 0158 hours on 09/30/99.                                             |

| The licensee notified the NRC resident inspector, the states of Delaware and |
| New Jersey, and the Lower Alloways Creek Township.  The NRC operations       |
| officer notified the R1DO (Silk), NRR EO (Marsh), IRO (Giitter), and FEMA    |
| (Caldwell)                                                                   |
