| STOLEN TROXLER MOISTURE DENSITY GAUGE |
| |
| The licensee reported a Troxler moisture density gauge (model 3430, serial |
| number 28862) stolen some time last night after 2110 EST from the cargo area |
| of a locked Nissan Pathfinder. The gauge was in a locked box in the vehicle |
| at the technician's home in Cincinnati. The gauge sources contain 8 mCi of |
| Cs-137 and 40 mCi of Am/Be-241. The City of Cincinnati Police responded and |
| are investigating the theft (no report number at this time). The licensee |
| notified the Ohio Bureau of Radiation Safety, part of the Department of |
| Health as part of their license requirement. |

| AGREEMENT STATE/TRANSPORTATION EVENT INVOLVING A BURNED FEDERAL EXPRESS |
| TRUCK CARRYING A GAUGE WITH A SMALL SOURCE IN IT |
| |
| On 3/21/00 at about 6:30 AM in Oxnard CA, a Federal Express truck burned due |
| to an unknown cause. It was discovered today, 3/23/00, that a thickness |
| gauge from NDC of Irwindale, CA was on the truck. The gauge contains a |
| special form source of Curium-244, 100 mCi. The source is thought to be |
| able to survive the fire and is being sought. Dr. Roy Parker, the Federal |
| Express Safety Officer, is on the scene and following up on the incident. |
| |
| The National Response Center report number is 523952. |
| |
| (Call the HOO for contact numbers) |
| |
| * * * UPDATE AT 1715 EST ON 3/24/00 BY DONALD BUNN TO FANGIE JONES * * * |
| |
| The source has been recovered intact from the fire debris, there has been no |
| release. Notified the NMSS EO (Larry Camper), R4DO (Lawrence Yandell), IRO |
| (Frank Congel), DOT (Matt Robertson), and DOE (Mike Wyatt). |

| - 'C' INBOARD MAIN STEAM ISOLATION VALVE FAILED ITS LOCAL LEAK RATE TEST - |
| |
| During the performance of a local leak rate test of the 'C' main steam |
| isolation valves (MSIVs) with Unit 1 in a refueling outage, the inboard MSIV |
| #HV141-F022C was unable to hold pressure. This constitutes a failure of the |
| maximum path leak rate required by Tech Spec 3.6.1.3. |
| |
| This condition constitutes a degraded condition of a principal safety |
| barrier found while Unit 1 was shutdown. No other adverse conditions were |
| identified. |
| |
| Unit 1 remains safely shutdown and the licensee is conducting an |
| investigation to determine the cause of the failure. |
| |
| The licensee plans to notify the NRC Resident Inspector. |

| - CONTROL ROD DROPPED INTO THE CORE DURING CONTROL ROD MOTION TESTING - |
| |
| While performing control rod motion testing, plant technicians were checking |
| the control rod fuses and caused a fuse to blow which caused control rod #48 |
| to drop into the core. Plant operators reduced power from 100% to 70% and |
| are in the process of retrieving the dropped control rod and are |
| investigating the cause of the blown fuse. |

| - NRC BULLETIN 91-01, 24 HOUR REPORT - |
| |
| During chemical cleaning of motor brake pads in the C-400 alkali tank, it |
| was discovered that the brake pads were placed in the alkali tank before |
| being verified to meet unconditional release limits, in violation of NCSA |
| 400.011. |
| |
| Compliance with unconditional release limits requires both a removable |
| contamination smear and a fixed uranium contamination survey. The fixed |
| contamination survey was omitted. Compliance with unconditional release |
| limits and a visual inspection for uranium contamination are used to ensure |
| that unknown quantities of fissile material do not enter the alkali tank. |
| The visible inspection required was properly performed. A determination |
| that assay was 5.5 wt% is also required and was performed and documented. |
| However, the determination was documented on the C-400 Chemical Cleaning Log |
| sheet, instead of the form required by CP2-EG-NS1O33. |
| |
| |
| SAFETY SIGNIFICANCE OF EVENTS: |
| |
| The visual inspection of the brake pads showed no uranium contamination and |
| this equipment is not directly in contact with process UF6. The potential |
| for introduction of U-235 into the alkali tank from the brake pads is |
| extremely low, a control relied upon for criticality safety was violated. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED [BRIEF SCEANARIO(S) OF HOW |
| CRITICALITY COULD OCCUR]: |
| |
| In order for a criticality to be possible, the accumulation of fissile |
| material involving an unsafe mass and geometry would have to occur. |
| However, since the visual inspection showed no contamination, an |
| accumulation of U-235 above assumed limits did not occur. These limits are a |
| small fraction of the unsafe mass value, |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC.): |
| |
| Double contingency for this scenario is established by implementing two |
| independent controls on mass. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE CRITCAL MASS): |
| |
| No visible contamination. Therefore, the mass is zero grams. |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| The first leg of double contingency relies on a visual inspection of all |
| internal and external surfaces for uranium contamination to verify no visual |
| contamination. Verification of no visual contamination ensures the mass |
| limit is maintained for assays 1000X | |
