| Title | Part 21 - Insufficient Spot Weld on Wire Wound Resistor |
| Event Description | The following information was excerpted from a facsimile from AMETEK Solidstate Controls:
Ohmite 5 watt, 470 ohm wire wound resistor with component Date Code 1201 is mounted on a printed circuit board installed in power supplies manufactured by Ametek Solidstate Controls. Component Description: Ohmite 5 watt, 470 ohm wire wound resistor with Date Code 1201 Problem You Could See: Internal open - (100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> burn-in performed) Probable Cause: Insufficient spot weld on the wire wound resistor Effect on System Performance: Resistor opens Action Required: Notify NRC and affected utilities. Prepare replacements. Ametek Solidstate Controls Corrective Action Taken: Notified affected utilities of the potential defect and advised that the power supplies be returned to our factory. Further corrective action will be to install new boards with unaffected resistors, retest, perform 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> burn in and return.
