| 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. |

| SMALL URANIUM HEXAFLUORIDE RELEASE ONSITE |
| |
| The licensee reported that from 0945 to 0950 CDT, a small UF6 release |
| occurred in the feeds material building. No material left the site, nor did |
| the licensee declare an Alert. Two individuals were exposed to fumes from |
| the leak. Those individuals were treated with oxygen at the facility and |
| transported to a local hospital. The UF6 leak has been stopped. |
| |
| The exact quantity of material released has yet to be determined. The |

| 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. |

| OUTAGES FROM ELECTRICAL STORMS |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "[A total of 26 out of] 97 emergency preparedness sirens (>25%) are out of |
| service due to power outages from electrical storms. [This includes 20 out |
| of] 27 in York County, 2 in Herford County, 2 in Lancaster County, 1 in |
| Cecil County, and 1 in Chester County. Plans are in progress to restore |
| power." |
| |
| The licensee reported that all systems functioned as required and that there |
| was nothing unusual or misunderstood. The licensee also reported that there |
| was no loss of offsite power. |
| |
| The licensee notified the NRC resident inspector. |

| UNPLANNED REACTOR PROTECTION SYSTEM (RPS) SYSTEM/SAFETY SYSTEM ACTUATIONS |
| WHILE CRITICAL |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "[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. |
| |
| The licensee notified the NRC resident inspector. |

EVENT TEXT

| MANUAL REACTOR SCRAM DUE TO DECREASING REACTOR WATER LEVEL AND GROUP 1 |
| ISOLATION DUE TO LOW REACTOR PRESSURE WHILE IN RUN |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "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. |
| |
| The licensee notified the NRC resident inspector. |
