| UNEXPECTED REACTOR SCRAM DURING LOGIC SYSTEM TESTING OF EMERGENCY BUS A5.    |
|                                                                              |
| Pilgrim Unit 1 scrammed from 100% during performance of Logic System Testing |
| of Emergency Bus A5.  This is the first time that  the Logic System Testing  |
| of Emergency Bus A5 had been performed at power. The test is performed once  |
| every 24 months and had just been rewritten to be performed at power.  The   |
| cause of the scram is under investigation at this time but the initiating    |
| transient was the loss of Emergency Bus A5.  All rods fully inserted into    |
| the core.   The plant is at 700 lbs. and a controlled depressurization is in |
| progress.  Plans are to cool down to less than or equal to 150 lbs. and      |
| repair the outboard RCIC steam isolation valve.                              |
|                                                                              |
| Due to deenergization of Emergency Bus A5, Recirculation Pump A tripped and  |
| there was a fast transfer of the swing bus (this was expected).  The         |
| licensee is looking into the transfer of the swing bus causing the trip of   |
| Recirculation Pump B.  Loss of both operating Recirculation Pumps at power   |
| will cause a reactor scram.    All systems operated properly.  The           |
| electrical grid is stable and all Emergency Core Cooling systems are fully   |
| operable if needed.  The Recirculation pumps will be restarted when the      |
| differential temperature between the top and bottom head are within          |
| specification.                                                               |
|                                                                              |
| The NRC Resident Inspector was notified of this event by the licensee.       |
|                                                                              |
| **** UPDATE ON 08/14/01 AT 1338ET BY V. FALLACARA TAKEN BY MACKINNON ****    |
|                                                                              |
| This is a supplement report to detail additional information on the scram a  |
| Pilgrim, Unit 1 on 08/13/01.                                                 |
|                                                                              |
| Upon further evaluation of the event and the requirements of 10CFR50.72 and  |
| NUREG-1022,  Pilgrim is reporting the valid actuation of the following       |
| containment isolation groups immediately following the scram: Group 2        |
| (Secondary Isolations), Group 6 (Reactor Water Cleanup), and Reactor         |
| Building Isolation with initiation of Standby Gas Treatment Systems. These   |
| are expected occurrences in a post-scram transient due to reactor water      |
| level shrink below the Reactor Level Setpoint of + 12".                      |
|                                                                              |
| Further plant response issues which are currently under investigation        |
| include:                                                                     |
|                                                                              |
| Finalizing the cause of the "B" side RPS actuation.                          |
| Determining the cause of the loss of "B" Recirculation Pump.                 |
| Resolving a falsely pegged level indication on the "A" Reactor Water Level   |
| Indication.                                                                  |
| Determining the cause of the loss of 120 VAC bus Y-4.                        |
|                                                                              |
| An event analysis team has been formed to drive out all of these issues.     |
| R1DO (Ron Bellamy) notified.                                                 |
