| MANUAL REACTOR TRIP DUE TO LOSS OF MAIN CONDENSER VACUUM |
| |
| The reactor was manually tripped (all rods inserted) due to low main |
| condenser vacuum at 1236 EDT. The cause of the low vacuum is under |
| investigation and is unknown at this time. When the trip occurred the 'A' |
| side non-essential 6.9 kV bus failed to transfer from the auxiliary (plant) |
| power to startup (offsite) source resulting in the loss of two of four |
| reactor coolant pumps. The cause of the failure to transfer is also unknown |
| and under investigation. |
| |
| The plant is stable in hot standby with forced circulation via the remaining |
| two reactor coolant pumps. Feedwater is via the main feedwater system and |
| steaming is via the steam bypass system. |
| |
| The licensee notified the NRC Resident Inspector. |
| |

| *** UPDATE ON 8/24/99 @ 0915 BY HALL TO GOULD *** |

| THIS UPDATE IS TO INCLUDE THE ACTUATION OF THE AFAS-2 (AUX FEEDWATER |
| ACTUATION SYSTEM) FOR 4 MINS TO THE #2 STEAM GENERATOR. THIS RESPONSE IS |
| EXPECTED AND NORMAL. |

| UNAVAILABILITY OF NOTIFICATION SYSTEMS FOR PAGER ACTIVATION |
| |
| On 8/24/99 the station was conducting an Emergency Plan Drill. During the |
| activities one of the participants learned that the telenotification system |
| (including its backup) which is used to page individuals in the event of an |
| actual emergency had failed. In accordance with 10CFR50.72(b)(1)(v) this |
| constitutes a Loss of Emergency Response Capability . |
| |
| The telenotification system is now operable. The licensee determined that a |
| power source was disconnected. |
| |
| The NRC resident inspector has been notified. |

| ENGINEERED SAFETY FEATURES ACTUATION DUE TO AN ELECTRICAL FAULT |
| |
| "At 1438 Hrs, August 24, 1999, the Unit 2 Standby Transformer locked out due |
| to an electrical fault on one of the lighting arrestors installed on the |
| transformer. Due to the loss of power to the Unit 2 Standby Transformer, the |
| Train C Standby Diesel Generator started and loaded all Mode II (LOOP) |
| Engineered Safety Features equipment as required. The Train 'B' Standby |
| Diesel Generator was in service for monthly surveillance testing at the time |
| of the event, so the Train 'B' Engineered Safety Features equipment never |
| lost power. |
| |
| "The electrical voltage perturbation also resulted in a Reactor Coolant |
| System letdown isolation. Letdown has subsequently been returned to service |
| for Reactor Coolant System inventory control. Also, two radiation monitors |
| used to monitor plant radiological effluents were affected by the voltage |
| perturbation. The Condenser Air Removal System Radiation Monitor RT-8027 |
| momentarily lost communications with the Radiation Monitoring System |
| Computer. The condition has cleared and the monitor has been returned to |
| service. The Unit Vent Radiation Monitor RT-8010A lost communication with |
| the Radiation Monitoring System Computer during the perturbation as well. |
| This monitor remains out of service (the Wide Range Unit Vent Accident |
| Radiation Monitor RT-8010B remained in service through out the event). |
| |
| "Unit 2 is currently stable at 100% power. Preparations are being made to |
| reenergize the deenergized Unit 2 Standby Buses from the Unit 1 Standby |
| Transformer. |
| |
| "In addition to the start of the Train 'C' Standby Diesel Generator, the |
| Train 'C' Centrifugal Charging Pump and the Train 'C' Auxiliary Feedwater |
| Pump also started as required. The automatic actuation of these Engineered |
| Safety Features components is reportable per 10 CFR 50.72(b)(2))." |

| POSSIBLE OVEREXPOSURE TO EMPLOYEES' EXTREMITIES |
| |
| Eastern Isotopes received their June 1999 exposure report from their vendor, |
| Proxtronics (Burke, VA), which indicated one individual received 50 rem to |
| the extremities as indicated by finger rings. The report also indicated |
| that two other individuals received higher than expected doses to their |
| extremities, 25 rem and 36 rem. Initial investigation indicated that the |
| highest dosage occurred to an individual who had the least number of duties |
| involving possible exposure. The individuals involved have been removed |
| from duties involving further exposures while further investigations are |
| carried out. The vendor has been contacted and suspects their standards and |
| controls, which they are investigating. A preliminary report from the |
| vendor is expected tomorrow. |
| |
| Eastern Isotopes handles Technetium and F18 (FDG). |

| UNEXPECTED HIGH PRESSURE COOLANT INJECTION SYSTEM SUCTION SWAPOVER DURING |
| ROUTINE EMERGENCY DIESEL GENERATOR TESTING |
| |
| While using the "Diesel Generator Undervoltage Test Auto Start Switch" to |
| start the 'B' emergency diesel generator as part of a routine surveillance |
| test, an unexpected high pressure coolant injection system suction swapover |
| occurred, and three valves actuated to swap the suction from the condensate |
| storage tank (normal) to the torus. Apparently, a low spike was received on |
| both the DC1 system and condensate storage tank level when the "Diesel |
| Generator Undervoltage Test Auto Start Switch" was operated. After the |
| condensate storage tank and torus levels were verified to be normal, the |
| licensee swapped the high pressure coolant injection suction back to its |
| normal lineup. The licensee is currently investigating the cause of this |
| transient. |
| |
| The 'B' emergency diesel generator started as expected. |
| |
| The licensee plans to notify the NRC resident inspector and the State of |
| Vermont. |
