| STOLEN HUMBOLDT 5001C NUCLEAR GAUGE                                          |
|                                                                              |

| The gauge was lost during the hours of darkness July 15-16, 2001, from the   |
| back of a truck that was parked overnight at the home of the driver.  The    |
| gauge and it's transport case were removed from a parked pickup truck by     |
| cutting the chain securing the gauge to the bed of the truck.  Also stolen   |
| during this incident was the operator's toolbox and assorted hand tools.     |
| The gauge is a Humboldt Model 5001C, Serial  # 2606, containing two          |
| radioactive sources: 10 millicuries of cesium-137, Serial #6171GQ; and 40    |
| millicuries of americium-241;Be, Serial # NJ02767.  A police report was      |
| filed on July 16, 2001, with the Dallas Police Department (Report #          |
| 0551265-K).  A press release offering a $250 reward for the return of the    |
| gauge was run in the Dallas Morning News for two days.  The gauge has not    |
| been recovered as of this date.  The licensee has been cited for failure to  |
| maintain the gauge under constant surveillance.  The state of Texas has      |
| informed the Radiation Control authorities in Mexico, Arizona, New Mexico,   |
| Arkansas, and Louisiana, as well as the Humboldt Radiation Safety Officer.   |

| PLANNED OFFSITE NOTIFICATION REGARDING A FISH KILL IN THE DISCHARGE QUARRY   |
| DUE TO A RECENT SUSTAINED HEAT WAVE IN THE NORTHEAST                         |
|                                                                              |
| The following text is a portion of a facsimile received from the licensee:   |
|                                                                              |
| "A visual inspection by Millstone [station biologists] on August 10, 2001,   |
| revealed approximately 50 dead [Tautog] (blackfish) in the discharge quarry  |
| by the fish barrier.  A subsequent dive into the quarry by station           |
| biologists [revealed] 2 additional dead Tautog along the fish barrier.  No   |
| additional moralities or other species were found on the bottom of the       |
| quarry."                                                                     |
|                                                                              |
| "The fish most likely died as a result of the sustained elevated             |
| temperatures during the week of August 6, 2001, experienced throughout New   |
| England and Connecticut.  Intake water temperatures have risen above 70      |
| degrees F with discharge temperatures about 98 degree F.  Water temperatures |
| in the quarry have climbed to above 90 degrees F at times during the week.   |
| Tautog are known to have decreased resistant when water temperatures are     |
| above 90 degrees F."                                                         |
|                                                                              |
| "Station [biologists] continue to monitor fish in the quarry."               |
|                                                                              |
| The licensee stated that there was nothing unusual about the temperature     |
| deltas across the condensers and that discharge temperatures are normal.     |
| The licensee also stated that load has been reduced on Unit 2 in order to    |
| keep condenser pressure below the condenser low pressure alarm setpoint and  |
| to maintain discharge temperatures within acceptable limits.  The discharge  |
| temperatures for Unit 3 were reported to be normal with the unit at full     |
| power.                                                                       |
|                                                                              |
| The licensee plans to notify the NRC resident inspector and the State        |
| Department of Environmental Protection.                                      |

| "[The unit] received [an] isolation of the [transverse incore probe (TIP)]   |
| purge system and the offgas system during [an] electrical transient on the   |
| 230kV distribution system.  [The licensee believes] the isolations were      |
| caused by the voltage fluctuations felt in the plant from the grid.  Since   |
| the TIP purge isolation is processed through [the reactor protection system  |
| (RPS)] and offgas from the offgas [radiation] monitors, this falls under     |
| actuation of a safety system while critical."                                |
|                                                                              |
| "[The licensee] reset isolations and restored systems to normal."            |
|                                                                              |
| The licensee stated that the isolation signals that were processed did not   |
| show up on any alarms.  Alarms were received but nothing specific to         |
| indicate the isolations.  This may have been due to voltage                  |
| fluctuations/losses as a result of power/instrument panels that transferred  |
| to their alternate power supplies.  The voltage fluctuations on the in-house |
| 4160V buses were attributed to the electrical transient on the 230kV         |
| distribution system.                                                         |
|                                                                              |
| There was severe weather in the area at the time of this event.  As a        |
| result, one of two 230kV outgoing power lines and both 34.5kV feed lines     |
| were lost.  All of these lines have since been returned to service.  The     |
| licensee stated that offsite power was never lost because one 230kV line     |
| remained available to backfeed/supply the 34.5kV buses.                      |
|                                                                              |

| "At 07:46:00 [CDT], a reactor water low-level alarm was received.  The       |
| reactor operator verified the low-level condition and took manual control of |
| feedwater level control.  The operator matched feedwater and steam flow.  At |
| 07:46:28 [CDT], the 'B' feedwater pump tripped on low suction pressure.  A   |
| manual scram was inserted at 07:46:42 [CDT] due to lowering reactor water    |
| level.  Level dropped below 170 [inches] on the reactor scram [as expected], |
| and [Group 2, 3, and 4 isolations] were received.  All isolations went to    |
| completion.  At 07:47:48 [CDT], a Group 1 isolation was received on the 850  |
| psig low reactor pressure in Run isolation signal.  The operator was in the  |
| process of [taking] the mode switch [out of] Run, but the isolation occurred |
| before this action could be completed.  All [main steam isolation valves]    |
| closed on the Group 1 isolation signal.  Reactor level increased to the high |
| level trip following the reactor scram, as expected, and the 'A' feedwater   |
| pump tripped.  Due to the Group 1 isolation, the operating crew elected to   |
| manually initiate Low Low Set pressure control using the safety relief       |
| valves.  A relief valve was opened, arming Low Low Set, and the two valves   |
| lowered reactor pressure to 900 psig.  The Group 1 was reset, and main steam |
| line drains to the condenser are being used to control pressure.  The 'A'    |
| feedwater pump high level trip has been reset and is maintaining level."     |
|                                                                              |
| "All systems responded as expected.  The plant is currently in Hot Shutdown  |
| at 800 psig.  Plans are being reviewed to determine the length of the forced |
| outage.  Preliminary investigations indicate that the 'B' feedwater pump     |
| minimum flow valve may have failed open to initiate the event."              |
|                                                                              |
| The licensee stated that there were no maintenance or surveillance           |
| activities ongoing at the time of the event.  All control rods fully         |
| inserted following the manual reactor scram.  All containment parameters are |
| currently normal, and offsite power is available.                            |
