| On 4/24/2001, an irradiator facility experienced a loss of electrical power  |
| to a programmable logic controller (PLC) which resulted in the inability to  |
| automatically lower the source racks. The source racks were manually lowered |
| to a safe condition upon discovery of the failure.                           |
|                                                                              |
| The following information was provided by the licensee to the California     |
| Radiation Control Program on 5/15/2001:                                      |
|                                                                              |
| "Description of Events:                                                      |
|                                                                              |
| "The first indication that there was a problem came at 9:00 p.m. 4/24/01,    |
| when the in-line water monitor signaled a failure. The Shift Leader took     |
| appropriate action per the Emergency Procedures and determined that there    |
| was no radiation present in the water system. He notified the QA Technician, |
| who had performed a calibration of the monitor that afternoon.               |
|                                                                              |
| "After reviewing the procedure followed for calibration routine and          |
| determining that no problems occurred with the calibration that would trip   |
| the alarm, the QA Technician, notified the facility Radiation Protection     |
| Office (RPO). She determined that this was a false alarm, probably caused by |
| air bubbles in the system, as has previously occurred with the water         |
| monitor. [... Permission was given] to allow the system to continue running  |
| with the water alarm disarmed until more investigation could be performed in |
| the morning.                                                                 |
|                                                                              |
| "Starting at about 7:00 a.m., additional water counts, using the monitor,    |
| were taken and resulted in normal background readings. Since the routine     |
| counts showed expected background levels and the alarm did not activate      |
| again, the concluded that a pocket of water bubbles from a filter change had |
| worked its way through the system and caused spurious readings on the        |
| monitor, which had occurred on previous occasions. All of the events to this |
| point were consistent with this determination.                               |
|                                                                              |
| "At 8:20 am., the Operator notified the RPO that the in-line alarm was       |
| sounding again. On reviewing the PLC control panel, she noted that none of   |
| the indicators on the panel were lit, as they should have been, even though  |
| the computer monitor (PLC user interface) was operating. In concert with the |
| Plant Manager, they determined that the audible alarm that the Operator      |
| heard was not the in-line monitor, but was an alarm indicating that the PLC  |
| was off-line.                                                                |
|                                                                              |
| "Further investigation revealed that the system conveyor had stopped moving  |
| (i.e., product was stationary within the cell), but that the source racks    |
| bad not automatically returned to the shielded position, as they should      |
| have, the source racks were manually lowered from the roof by 8:40 a.m.      |
| During this time, the door interlock continued to function properly,         |
| prohibiting access to the cell through the personnel access door.            |
|                                                                              |
| "In determining the probable cause of the event, the first evaluation was    |
| that the power supply had malfunctioned. However, upon further               |
| investigation, it was determined that the most probable cause was an         |
| electrical short in the system. After extensive trouble-shooting and         |
| investigation, the electrical short was finally located in the line going to |
| one of the emergency pull cords in the cell. The cable had actually melted   |
| at the point of the failure.                                                 |
|                                                                              |
| "That part of the systems was rewired and the system restarted at            |
| approximately 4:00 p.m. The safety system was checked for proper operation   |
| and routine processing resumed at 4:45 p.m.                                  |
|                                                                              |
| "Evaluation of Event and Root Cause:                                         |
|                                                                              |
| "Upon Engineering review of the electrical drawings, it was determined that  |
| a short circuit on the pull cords or other devices could have tripped one of |
| the circuit breakers, power from which feeds the PLC and other modules in    |
| the PLC rack. The audible alarm was the PLC Off Line Sonalert, which, as     |
| intended, served as a warning the PLC was not operating. With the PLC off,   |
| there was no power control to lower the source racks. In normal              |
| circumstances of power failure, the uninterruptible power supply (UPS)       |
| provides adequate emergency power to lower the source racks by releasing the |
| hoist brakes in a pulsed mode. However, with the PLC not operating, this     |
| power was not supplied to the brakes, which then had to be released          |
| manually.                                                                    |
|                                                                              |
| "The water monitor alarm activation was probably caused by shorting line     |
| voltage to the grounding circuit. This momentary surge in current,           |
| particularly on the ground path, could cause an erroneous indication at the  |
| monitor. Other facilities have had spurious water monitor alarms resulting   |
| from ground fault conditions.                                                |
|                                                                              |
| "Corrective Actions and Additional Considerations:                           |
|                                                                              |
| "Corrective actions to the event are:                                        |
|                                                                              |
| "1.     The circuit will be modified to ensure the PLC does not lose power   |
| if a device or device wiring causes a short circuit.                         |
|                                                                              |
| "2.     Additional training will be provided to operators to be more         |
| cognizant of the system response to a PLC off-line fault. While the PLC      |
| off-line alarm is a local alarm, meaning that it sounds at the control       |
| console and does not active general alarms throughout the warehouse, all     |
| system operations are stopped, including overhead conveyors and the 4-shelf  |
| elevator (i.e., device that shifts totes among positions in the carrier).    |
| The absence of movement in these systems should have alerted the operator to |
| a systemic failure of the controls. In this instance, the tune period        |
| between the equipment failure and initial resolution (manually lowering the  |
| source racks) was only a few minutes. Because the door interlock continues   |
| to function under these circumstances, the situation did not pose a          |
| radiation safety hazard to the operator or other personnel. Although,        |
| operator training currently includes instructions for determining console    |
| power status and the proper procedure for lowering the source racks under    |
| circumstances such as occurred here, the training will be reinforced and     |
| repeated                                                                     |
|                                                                              |
| "3.     To avoid further problems with the in-line water monitor alarm, an   |
| evaluation is being conducted to determine whether the water monitor can be  |
| connected to an isolated-ground receptacle and circuit. This would have the  |
| effect of making the monitor less affected by stray currents, and other      |
| sources of 'noise' on the power line."                                       |
|                                                                              |

| TROXLER GAUGE STOLEN FROM COMPANY TRUCK AT RESIDENCE                         |
|                                                                              |
| Sometime between 0200-0930 hours on 5/27 a company truck was broken into     |
| removing a Troxler gauge and it's case.  The gauge was properly stowed and   |
| it's case attached to the truck bed using a chain and lock.  The truck was   |
| parked overnight at the residence of the employee at 402 Lochmoor Drive in   |
| Temperance, MI.  The stolen Troxler is a model 3401B, S/N 13442, whose last  |
| measured activity on 4/30/01 was 5.6 mCi Cs-137 and 39 mCi Am-241/Be.  The   |
| Monroe County Sheriffs Department in Temperance, MI and Ohio Department of   |
| Health were both notified.  The licensee plans on issuing a press release.   |
