PLANT HAD AUTO START OF THE DIVISION 1 EMERGENCY DIESEL GENERATOR
"Undervoltage conditions were experienced on Division 1 emergency switchgear with subsequent start and load of the respective diesel generator [EDG]. A preliminary investigation indicates that an unexpected undervoltage signal was generated when technicians inadvertently contacted the wrong terminals during preparations for the respective division ECCS surveillance testing. All systems and equipment responded as required."
Power is still being provided (as of event reporting time) by the Division 1 EDG while they are working to restore normal power.
The licensee notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - UNEXPLAINED EXPOSURE DOSE
The following is a summary of a report submitted by the State of Texas to the NRC via email:
A radiographer employed by Texas Gamma Ray, LLC received an unexplained dose of 6730 mrem during the month of October 2004. Additional dose reported for the month of November 2004 increased the annual accrued dose for the year 2004 to 7780 mrem which exceeds the yearly occupational dose limit [5 Rem].
The licensee [Texas Gamma Ray, LLC] immediately informed the State of the overexposure via telephone and initiated an investigation. The investigation determined through interviews with the radiographer and a review of his October work assignments that he had dropped his film badge near a radioactive source (approximately 1 meter distance from a camera containing 30-40 Curies Ir-192) for about thirty minutes to an hour. The radiographer did not report the incident at that time or in his written statement describing his work activities. The licensee noted during their review of the monthly dosimetry monitoring reports provided by Atomic Energy Industrial Laboratory that two of the three individuals assigned to work with this radiographer wore spare film badges.
The State cited the licensee for eleven violations of their TX license. Texas Incident No. I-8190.
