An attempt to lower the source racks normally was unsuccessful. At approximately 0400 (PDT), the source racks were successfully lowered to the bottom of the pool following emergency operating procedures (EOP-034, Stuck Source Rack) for manually lowering the source rack. During this time, the irradiator entrance door remained secured by the safety system interlock system. </br>After some review and troubleshooting, the licensee determined that there was an electrical fault in a junction box which was later determined to have been caused by a degraded wire that short circuited to ground causing the electrical malfunction. The licensee subsequently replaced this degraded wire with new components.</br>Once repairs to the electrical system were completed and a functional safety system check of the irradiator was performed to determine that all safety systems were operating correctly, the licensee resumed operations." </br>California NMED Report Number: 050121s."
