| AREA CONTROL ROOM (ACR) ALARM POWER LOST DUE TO A FAILURE IN THE POWER |
| TRANSFER SWITCH |
| |
| "At 1610 on 08-30-00 the PSS was informed of a C-331 CAAS Cluster J Trouble |
| alarm. Investigation of trouble alarm revealed that C-331 CAAS Horns |
| solenoids had lost DC power. The C-331 ACR DC alarm power was lost due to |
| the failures in the power transfer switch. Contacts fused together and a |
| solenoid failed which allowed the transfer switch to reposition to the mid |
| (no power) position and prevented repositioning to the emergency power |
| position. Since the CAAS horns did not have power, they were unable to |
| perform the intended safety function, rendering the system inoperable for |
| audibility. The system is required to be operable according to TSR 2.4.4.7.b |
| for the current mode of operation. The horns were without power (inoperable) |
| for approximately 30 minutes until the transfer switch was physically forced |
| to the emergency power position. |
| |
| This event is reportable under 10 CFR 76.120(c)(2) as an event in which |
| equipment required by the TSR is disabled or fails to function as designed. |
| |
| The NRC Resident Inspector has been notified of this event. |

| 2 SETS OF CALIBRATION SOURCES DISCOVERED MISSING |
| |
| "At 10 AM on August 31, 2000 Global Nuclear Fuel - Americas determined that |
| two sets of instrument calibration sources are missing following a thorough |
| search. Each source set contains four metal disks electroplated with Pu-239, |
| Total activity contained in both source sets is approximately 1.7 |
| microcuries. The sources had been sent to a vendor for calibration |
| re-certification. |
| |
| "The sources were unaccounted for during a routine source inventory at |
| GNF-A. The vendor performing the calibration recertification last accounted |
| for the sources when shipped on August 2, 2000. Records of the common |
| carrier which transported the sources from the vendor to GNF-A indicate the |
| material was shipped as an excepted package limited quantity and delivered |
| to GNF-A on August 7. 2000. The inner packaging and each source are marked |
| with radioactive warning labels. There is no measurable radiation dose rate |
| from this type of package. A search of likely locations at GNFA has been |
| conducted with negative results. |
| |
| "This event is reportable pursuant to 10CFR20.2201, 10CFR70.52 and |
| 10CFR74.11. Efforts to locate the sources continue." |
| |
| The licensee intends to notify New Hanover County, North Carolina State |
| Department of Radiation Protection, and NRC R2(Ayers). |

| THE CONTROL ROOM EMERGENCY OUTSIDE AIR SYSTEM(CREOAS) FUNCTION IS DEFEATED |
| WHEN THE CONTROL ROOM SMOKE REMOVAL FANS OPERATE. |
| |
| On August 24, 2000, Susquehanna Unit 1 was Operating at 100% power and Unit |
| 2 was in Mode 2 at 0% power. Operations had placed the Control Structure |
| (CS) Smoke Removal ventilation system in service aligned to the Control Room |
| (CR) and Technical Support Center (TSC) areas to exhaust the foul odor |
| created by welding on the CR ventilation duct as part of modification work. |
| The CS Smoke Removal System was shutdown after personnel noticed a negative |
| differential pressure was created in the CR and TSC areas. This mode of |
| operation existed for 2 hours and 18 minutes. Subsequent review of the event |
| on August 31, 2000 concluded that when the CR Smoke Removal fans operate, |
| they act to defeat the function of the CREOAS fans which are intended to |
| maintain the CS pressure positive. Maintaining a positive pressure in the CS |
| assures that all air entering the CS has passed through the CREOAS filter |
| train (thus assuring no air enters via infiltration). |
| |
| The NRC Resident Inspector was notified. |

| PLANT ENTERED 72 HOUR LCO ACTION STATEMENT WHEN DIVISION III DIESEL |
| GENERATOR WAS DECLARED INOPERABLE |
| |
| During performance of Fire Protection Surveillance 9337.81 (performs a |
| functional check of the Division Ill Diesel Generator (DG) Carbon Dioxide |
| (CO2) system operation), the Division Ill DG ventilation system tripped |
| during restoration. Electrical Maintenance personnel were performing a |
| functional check of the Division Ill DG room thermal detectors when the |
| panel reset push button was depressed. The anticipated resets did not occur |
| and the decision was made to restore the system to a safe condition. During |
| restoration, a sticking relay prevented restoration of the Division Ill DG |
| ventilation system. The relay has been reset and the ventilation system |
| restored. |
| |
| Division Ill DG was declared INOPERABLE at 1747 and the plant entered LCO |
| 3.8.1. |
| Action B.1- Perform 9082.01 within 1 hour and every 8 hours thereafter. |
| Action B.2- Declare required features supported by Division Ill DG inop when |
| the redundant required features are inop, within 4 hours. |
| Action B.3.1- Determine Operable DG are not inop due to common cause failure |
| within 24 hours - This action -completed. |
| Action B.4- Restore Div 3 DG to Operable within 72 hrs. |
| Division Ill DG was declared OPERABLE at 1813 and the LCO was exited. |
| |
| The NRC Resident Inspector was notified.. |
