| AGREEMENT STATE NOTIFICATION OF IRRETRIEVABLE WELL-LOGGING SOURCE |
| |
| Timothy Bonzer of the Colorado Radiation Services notified the NRC |
| Operations Center via fax on 12/26/02 at 1135 EST on an incident involving |
| an abandoned well-logging source assembly at a gas well near Rifle, Colorado |
| by Schlumberger Technologies Corp. The sources (Cs and AmBe) were lost at |
| approximately the 8,000 ft level and efforts to retrieve the sources were |
| unsuccessful. They had taken the necessary measures to deflect any future |
| attempt to drill in the same location and will place a stainless steel |
| warning placard at the surface. They intended to abandon the sources and are |
| still planning to use the well for the production of natural gas. |
| |
| The Colorado Emergency Management organization is cognizant of this |
| incident. |

| AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE |
| |
| A Humbolt moisture density gauge , Model # HSI5001P, Serial # 838, was |
| stolen from the back of a truck sometime between 12/28/02 and 12/30/02 in |
| Redlands, CA. The gauge contained 10 millicuries of Cs-137 and 40 |
| millicuries Am-241:Be. On Saturday, December 28, 2002, an employee took the |
| gauge back to his residence after performing a job. The gauge was chained |
| and locked in the back of his truck. On Monday morning at approximately |
| 0645 PST the employee noticed that the gauge, chains and lock were missing |
| from the back of his truck. He reported the theft to the Radiation Safety |
| Officer (RSO). The RSO reported the theft to the State of California. The |
| theft was also reported to the local police and the licensee is posting a |

| MONTICELLO INITIATED TS REQUIRED PLANT SHUTDOWN DUE TO INOPERABILITY OF BOTH |
| EDGs |
| |
| "With #12 EDG inoperable due to a maintenance issue [on 12/29/02 at 2330 |
| CST] , it is required to test #11 EDG within 24 hours. Testing causes #11 |
| EDG to be inoperable, therefore both EDGs are inoperable requiring [the |
| initiation of] a plant shutdown per T.S. 3.9.B.3.a.2 and a non-emergency |
| notification per 10 CFR 50.72/8 hour. #11 EDG subequently tested operable |
| and the plant exited T.S. shutdown requirement at 2300 on 12/30/02." |
| |
| The licensee stated that the period of time both EDGs were inoperable was |
| from 2010 to 2300 on 12/30/02. The inoperablity of the #12 EDG was due to |
| an equipment problem with the DC fuel oil pump. After fixing the DC fuel |
| oil pump on the #12 EDG, the EDG was restarted and the "failure-to-start" |
| alarm lit and the "cranking" alarm lit and stayed in for 5 minutes. The |
| licensee is currently evaluating these problems. The #12 EDG remains in a 7 |
| day limiting LCO action statement. The #11 EDG started and tested |
| satisfactorily with no problems. The inoperability of the #11 EDG was due to |
| some of the set up conditions for testing when the EDG is considered to be |
| inoperable per procedure. |
| |
| The NRC Resident Inspector was notified. |

| "At 0626 EDT on 01/01/03, Sequoyah Unit 2 received reactor trip and |
| Auxiliary Feedwater (AFW) start signals while draining the loop 2 Steam |
| Generator (S/G). The low-low level trip inputs to the RPS (reactor |
| protection system) were blocked in accordance with the procedure. However, |
| the EAM/TTD [environmental adverse monitor/trip time delay] low-low level |
| trip inputs were not blocked prior to commencing the drain down [the |
| procedural step had been N/A'd]. The setpoint for the trip is 15% on 2/3 |
| Level Transmitters with an increasing time delay based on core delta T [with |
| reactor power less than 50%]. |
| |
| "Unit 2 was in Mode 5 [cold shutdown] prior the actuation with all rods |
| inserted. The reactor coolant system was at 115 [degrees] F and 5 psig. |
| The AFW pumps were in pull-to-lock and did not start as a result of the |
| signal. No other equipment started or repositioned as a result of the |
| low-low level signal. |
| |
| "The first out annunciation cleared at 0939 EDT after blocking the EAM/TTD |
| low-low level inputs." |
