| AGREEMENT STATE REPORT INVOLVING A STOLEN TROXLER MOISTURE DENSITY
GAUGE |
| |
| The following is the text from a NC Department of Environment and Natural |
| Resources News Release: |
| |
| "A truck stolen about 4:30 this afternoon in Forsyth County was transporting |
| an instrument containing eight millicuries of Cesium-137, a radioactive |
| material that is a potential health and safety risk if handled improperly or |
| broken open. |
| |
| "The truck is a white Ford F150. The instrument is a Troxler brand portable |
| moisture density gauge model 4640B. It is yellow and has a stainless steel |
| handle with a radiation symbol protruding from a heavy base. It is about |
| 20-30 pounds and 24x12x14 inches. Its serial number is 1996. The gauge was |
| in a yellow box 24x12 inches and marked as containing radioactive material. |
| The box should be locked and chained to the truck. |
| |
| "The gauge uses radioactive materials to test conditions of soil and asphalt |
| during construction. Any health risk would occur only if a person were |
| directly exposed to the sealed radioactive source inside the instrument. |
| |
| "Employees of Thompson-Arthur Division APAC-Carolina, Inc., a paving company |
| in Greensboro, left the truck unattended. The company's license with the |
| state Division of Radiation Protection requires that the instrument not be |
| left unsecured. |
| |
| "Anyone who believes he or she has found the truck, box or gauge should stay |
| at least ten feet away and contact the local sheriffs office, police |
| department or state highway patrol immediately." |
| |
| NC Incident No. 02-12. |
| |
| * * * UPDATED AT 0012 EST ON 3/31/02 BY LEE COX TO FANGIE JONES * * * |
| |
| The truck has been recovered by the Sheriff's department and will be picked |
| up by the North Carolina Division of Radiation Protection until the licensee |
| can take possesstion. The gauge in it's storage box was recovered |
| separately. The gauge and box appear undamaged and a survey will be |
| conducted when the North Carolina Division of Radiation Protection arrives |
| on scene. An additional report willl be sent later in the week. |
| |
| The R2DO (Carolyn Evans) and NMSS EO (Patricia Holahan) were notified. |

| TECHNICAL SPECIFICATION 3.0.3 ENTRY DUE TO LOW SERVICE WATER SUCTION
|
| PRESSURE AND THE SUBSEQUENT LOSS OF CHILLERS FOR THE CONTROL ROOM
EMERGENCY |
| OUTSIDE AIR SUPPLY (CREOAS) AND CONTROL ROOM FLOOR COOLING |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "Unit 1 was in Mode 5, day 28 of a refuel and inspection outage. Unit 2 was |
| in Mode 1, 24% power for scheduled maintenance work requiring River Water |
| Makeup to both units' cooling towers [to be] out of service." |
| |
| "At 2340 hours, Unit 1 began to experience low suction pressure to the 'C' |
| Service Water pump, the only pump in service at the time. Service Water |
| takes suction from the Unit 1 Cooling Tower, and this condition resulted in |
| low system discharge pressure and flow. Service Water is the normal cooling |
| source for Units 1 [and] 2 Control Structure [Heating Ventilation and Air |
| Conditioning (HVAC)]. The 'A' Control Structure chiller tripped, and the |
| 'B' Control Structure chiller failed to start due to the low flow condition |
| on service water. With both chillers tripped and unavailable for CREOAS and |
| Control Room Floor Cooling, [the Limiting Condition for Operation (LCO) for |
| Technical Specification] 3.0.3 was entered on Unit 2. This represented a |
| Loss of Safety Function for Accident Mitigation and requires an [8-hour] ENS |
| notification in accordance with 10CFR50.72(b)(3)(v)." |
| |
| "The Control Structure chillers were realigned to Emergency Service Water |
| (ESW), its backup emergency cooling source. The 'A' Chiller failed to |
| re-start, but the 'B' Chiller was successfully placed in service. LCO 3.0.3 |
| was able to be exited on Unit 2 at 0012 hours on 3/30/02." |
| |
| "An investigation is ongoing into why the 'A' Control Structure failed to |
| re-start and the cause of the low suction pressure on Service Water." |
| |
| The licensee stated that all systems functioned as required. |
| |
| The licensee notified the NRC resident inspector. |

| DIESEL GENERATORS DECLARED INOPERABLE FOR SHORT TIME PERIOD |
| |
| "During performance of 24 month Division 1 Diesel Generator LOCA/LOOP |
| surveillance testing, two pump start timers failed to meet the required |
| acceptance criteria. The A RHR Pump timer actuated at 3.72 seconds |
| (criteria: 2.7 sec. to 3.6 sec) and the C ESW Pump timer actuated at 39.24 |
| seconds (criteria: 39.6 sec. to 48.4 sec). With failure of the timers proper |
| loading on the Diesel Generators is not assured, and they ['A' and 'C'] were |
| declared inoperable until the associated pump control breakers were opened. |
| The Susquehanna safety analysis requires three operable Diesel Generators to |
| safely shutdown the plant. Therefore with only two operable Diesel |
| Generators, the condition requires an 8 hr ENS notification in accordance |
| with 10CFR50.72(b)(3)(v) and (vi)." |
| |
| With Unit 1 shutdown the 'A' RHR pump is not needed, but the 'C' ESW pump |
| does need to be operable resulting in part of the 8 hour report. |
| |
| The licensee notified the NRC Resident Inspector. |
