SAFETY SYSTEM ACTUATION
"At 0155 on 06-02-01 the Plant Shift Superintendent (PSS) was notified of an activation of the High Voltage UF6 Release Detection System at the C-315 Tails Withdrawal Building. An Instrument Mechanic was walking down job in preparation for connecting a safety sample buggy to valve SW-53. In order to verify which instrument line was the correct one to connect to the buggy, the mechanic moved the quarter inch copper line. The mechanic reported that the line broke and he saw smoke come from the area. Personnel in the area evacuated to the Area Control Room (ACR) and the Plant Emergency Squad was notified. Subsequent to the release, UF6 Detector heads YE-10-2-6 and YE-10-2-7 alarmed in the ACR. Detector head YE-10-2-6 is a TSR required Q component. The Plant Emergency Squad mitigated the release and the area was turned over to Operations.
"High volume air samples and wipe samples by Health Physics personnel indicate no widespread radiological contamination. Contamination was confined to the immediate area at the broken instrument line. Precautionary urine samples submitted by the two employees near the release indicated fluoride uptakes below plant recall limits of 5 mg/L. Analysis for uranium uptake indicated one employee's results were below detectable limits. The other employee's results indicated an uptake 7.3 µg U/L, which is above the plant recall limit of 5.0 µg U/L but below the restriction limit of 40 µg U/L. A follow-up urinalysis will be performed upon this employee upon his return to work at 1900 hours on 6-2-01.
"This safety system actuation is reportable to the NRC as required by Safety Analysis Report, section 6.9, table 1 criteria J.2, Safety System actuation due to a valid signal as a 24-hour event notification,
"The NRC Resident inspector has been notified of this event.
