| STOLEN TROXLER MOISTURE/DENSITY GAUGE |
| |
| On 12/29/98, the licensee discovered that a Troxler Model 3440 soil |
| moisture/density gauge (Serial #24596) had been removed from its case, which |
| was located in the back of a pickup truck. The gauge contains one 8-mCi |
| Cs-137 source, and one 40-mCi Am-241/Be source. When last seen on |
| 12/23/98, the gauge had been locked in its case, and the case had been |
| chained to the back of the pickup. A state investigator from the Miami |
| office has been dispatched to the scene, and the Metro-Dade police are |
| investigating the theft. |
| |
| * * * UPDATE AT 1131 EDT ON 4/8/99 BY CHARLES ADAMS TO FANGIE JONES * * * |
| |
| A fax from the Florida Department of Health Environmental Radiation Control |
| reported that a person, unknown, walked up to construction site personnel, |
| dropped off the gauge and left. Metro Dade Hazmat took possession of the |
| gauge. A survey showed normal readings. The owner has been contacted and |
| will take possession of the gauge. A leak test will be performed and |
| results passed to the state office. Metro Dade police is investigating. |
| |
| The NRC Operations Officer notified the R2DO (Walter Rogers) and NMSS (Don |

| COMMON FAILURE EFFECTING BOTH TRAINS OF SHUTDOWN COOLING |
| |
| "On 3/9/99, at 0221 it was discovered that the Unit 1 shutdown cooling |
| valves HV-51-1F015A, HV-51-1F015B, and HV-51-1F08 could not be opened, if |
| plant conditions required, due to a failure in the isolation logic circuit |
| connectors. |
| |
| "This failure affected both shutdown cooling return valves and a common |
| suction valve which results in one failure effecting both trains of shutdown |
| cooling. The identified deficiency is being planned for repairs. This |
| condition, of a single failure disabling multiple trains of a system, is |
| being reported pursuant to 50.72(b)(2)(iii)." |
| |
| This deficiency was discovered during routine maintenance. These valves |
| could be opened manually using existing plant procedures if it were |
| necessary to initiate shutdown cooling. |
| |
| The licensee will notify the NRC resident inspector. |
| |
| * * * RETRACTION 1421 4/8/1999 FROM McCABE TAKEN BY STRANSKY * * * |
| |
| "This is a retraction of Event # 35451: Common Failure Effecting Both Trains |
| of Shutdown Cooling |
| |
| "During normal operator rounds in the Auxiliary Equipment room, an operator |
| noticed an extinguished NSSSS indicator light. An attempt to reset that |
| portion of the logic circuitry failed. Troubleshooting revealed that there |
| was an open connection across a Grayboot electrical connector. The connector |
| was replaced and the system was returned to normal. The Residual Heat |
| Removal (RHR) - Shutdown Cooling Mode (SCM) was not in demand at any time |
| during the incident. Had the failure existed during a loss of coolant event, |
| high drywell pressure would have prevented the common suction valve for both |
| loops of RHR-SCM from initially being used. |
| |
| "A lab analysis of the failed electrical Grayboot connector revealed an |
| over-crimping of the connector during initial installation. The failure was |
| attributable to improperly setting the crimping tool from its initial |
| calibration setting prior to performing the final crimp. Six other Grayboot |
| connectors from various other Limerick Unit 1 and Unit 2 systems were |
| removed and analyzed in the lab. No similar incidences of over-crimping were |
| found, therefore the identified condition is considered not to be a generic |
| concern. |
| |
| "A licensing basis review for shutdown cooling was performed. Updated Final |
| Safety Analysis Report (UFSAR) section 7.4.1.3.1.1 states that '...The |
| system can use a preferred method to accomplish its design objectives by |
| directly extracting reactor vessel water from the reactor vessel via the |
| recirculation loop and routing it to a heat exchanger and back to the |
| vessel. An alternate method is to indirectly extract the water via relief |
| valve discharge lines to the suppression pool and route the suppression pool |
| water to the heat exchanger and back to the vessel. The redundancy and |
| diversity of RHR-SCM is also discussed in UFSAR Section 7.4.1.3.3.5. Failure |
| of RHR - SCM is analyzed in UFSAR Section 15.2.9. Also, UFSAR Section |
| 15.9.2.4 discusses alternate path availability to accomplish the shutdown |
| cooling function. |
| |
| "In addition, plant procedures exist to respond to a Loss of Shutdown |
| Cooling. The Shutdown Cooling system is initiated by Off-Normal procedure |
| ON-I 21, loss of Shutdown Cooling. Also, the other mechanism for SCM was |
| available and is also procedurally governed by S41 .7.B Use of SRV's and |
| Suppression Pool Cooling as an Alternate Shutdown Cooling Method. |
| |
| "Based on our review of the licensing basis for shutdown cooling, we |
| determined that the Shutdown Cooling System was not rendered incapable of |
| performing its design safety function." |
| |
| The licensee will inform the NRC resident inspector of this retraction. |

| AGREEMENT STATE REPORT - LOST DELIVERY CASES |
| |
| NC Division of Radiation Protection was informed April 8, 1999, by Syncor |
| International Corporation that one of their Nuclear Pharmacies lost control |
| of five delivery cases containing Limited Quantity Shipments (LQS) returned |
| from customers. The pharmacy is located in Charlotte, NC (Radioactive |
| License No. 060-0794-1). On October 30, 1998, the delivery cases were |
| inadvertently left within the trunk of a delivery vehicle which had been |
| rendered inoperable in an accident. The car was transferred through a series |
| of wrecker and garage services (without a set of keys), eventually being |
| sold to a resident of TN. The new owner purchased the vehicle on April 2, |
| 1999, in SC, returned it to TN and had keys made. The delivery cases were |
| discovered April 3, 1999, when the owner opened the trunk for the first |
| time. The owner notified TN authorities who were able to determine the |
| origin of the delivery by paper work located with the cases. TN authorities |
| contacted Syncor International Corporation which dispatched trained |
| employees to recover the delivery cases. Surveys performed at the time of |
| recovery indicated no exposure rates above background or indications of |
| contamination. |
| |
| |
| NC Division of Radiation Protection is working with the TN Dept. of |
| Environment and |
| Conservation Div. Of Radiological Health SC Agreement State Program and |
| Syncor |
| International Corporation to fully investigate this event. |
| |
| This event was sent by facsimile to the NRC Operations Center. |

| CONTROL ROOM VENTILATION INTAKES ISOLATED |
| |
| The Unit 2 Control Room Ventilation (VC) intake was isolated when valve |
| 2VC6A automatically closed due to a (suspected) invalid high chlorine |
| signal. During troubleshooting activities, a maintenance technician |
| inadvertently closed valve 1VC5B (the Unit 1 VC intake) when he depressed |
| the associated chlorine detector reset button. (The technician mistakenly |
| thought that the VC intake for Unit 1 was isolated.) Control room operators |
| immediately discovered the error and reopened valve 1VC5B. As a result of |
| this event, both units entered Technical Specification 3.0.3 for |
| approximately one minute. The NRC resident inspector will be informed of |
| this notification by the licensee. |

| HPCI TEMPORARILY INOPERABLE |
| |
| System Affected: During performance of regularly scheduled Instrumentation |
| surveillance on Unit 3 HPCI Steam Line Space High Temperature switches (in |
| accordance with plant procedure 3-SR-3.3.6.1(3D)) personnel noticed that a |
| relay not tested by procedure was chattering. The affected relay |
| 3-RLY-073-23A-K16 was adjacent to a relay 3-RLY-073-23A-K8 which was being |
| tested by the surveillance. While troubleshooting the cause of the |
| chattering relay, a loose wire was found in the power supply pathway for |
| the HPCI logic circuit. This loose wire had the potential to prevent |
| adequate voltage being supplied to the initiation and isolation logic for |
| the Unit 3 HPCI system. |
| |
| Actions: The loose wire was retightened. |
| |
| Reportability: The potential for inadequate voltage being available for the |
| HPCI logic circuit resulted in a conservative decision to declare the HPCI |
| system inoperable. In accordance with plant procedure SPP 3.5, code of |
| Federal Regulations 10CFR50.72/73 and NUREG 1022 Rev 1 this is reportable as |
| a 4 Hour Non-Emergency report due to any event or condition that alone could |
| have prevented the Fulfillment of the safely function of structures or |
