AGREEMENT STATE RADIOACTIVE CONTAMINATION DUE TO MELTED SOURCE

State of Ohio reported that a Cs 137 source was destroyed in a furnace at the Timken Steel Company. The initial detection of a problem occurred with high radiation being detected in the bag house exhaust system. Dose rates are 660 micro R/hr in the bag house. It is not known at this time the origin of the radioactive material. The licensee is conducting surveys to determine if there is contamination anywhere else in the facility. The licensee is also conducting an inventory of their radioactive material to determine if it was their material. It is suspected that the radioactive material may have been in a load of scrap steel that was being melted for reprocessing. The licensee has contacted a contractor to perform decontamination activities.

Licensee notified the NRC Agreement States representative (J. Lynch).

BOTH UNIT 2 EMERGENCY DIESELS DECLARED INOPERABLE DUE TO SHIMS/SUPPORTS FOUND TO BE EITHER MISSING OR NOT PROPERLY FASTENED.

"2-EE-EG-2H was out of service for scheduled maintenance. During an inspection, 4 shims on the exhaust stack seismic support on the south wall were found missing. The shims provide baseplate bearing on the concrete wall near each anchor bolt and had fallen to the floor. In addition, both lower anchor bolt nuts had worked loose and had fallen to the floor and one of the upper anchor bolt nuts had worked loose and was partially disengaged.

"Following this discovery 2-EE-EG-2J was inspected and 3 of the 4 supports were not properly fastened. 2J EDG was declared inoperable based on this discovery. Due to both U-2 Emergency Diesel Generators being in operable the safety functions needed to maintain the reactor in a safe shutdown condition and remove residual heat would have been imparted in the event of a loss of off site power

"2-EE-EG-2J was repaired and returned to operable at 2313 EST on May 09, 2004."

The NRC Resident Inspector was notified of this event by the licensee.
