SPILL OF SEWAGE SLUDGE

"At approximately 1100 hours on November 19, 2007, waste treatment operators noticed that the sewage sludge pump transferring material to the LLR press, located at the Waste Treatment Facility, had split and that sludge material had been released. The volume of sludge material that was released is estimated to be less than 150 gallons. The material was released in the pump house and flowed to a gravel area north of the pump house and extended into a storm water drainage ditch. A small quantity of material appeared to collect in the ditch, but did not flow off-site. Operators contained the spilled material and cleaned the affected areas in less than 24 hours.

"Facility sewage is of low activity due to natural content and the possible presence of trace material due to trace contamination in the associated piping system. The material is known to be << [much less than] 30 pCi/g [picoCuries per gram]. The total activity spilled including natural background is estimated to be less than 6 uCi [microCuries] using a maximum concentration of 10 pCi/g and 150 gallons of material. Both values are conservative. A study is in progress to determine if licensed material was actually present.

"On November 20,2007, as required by our VPDES Permit Number 0003697, the Virginia Department of Environmental Quality was notified of this non-permitted release to the environment.

"BWXT is making this concurrent notification in accordance with 10 CFR 70 Appendix A(c)."

There was no other potentially hazardous material released.

The licensee notified the NRC Resident Inspector.

ALERT DECLARED DUE TO OXYGEN DEFICIENT ATMOSPHERE

An ALERT was declared at 0915 CST. A nitrogen freeze seal was being used on a 3 inch pipe in the 1B RHR and 1B Containment Spray pump room. A leak developed on the freeze seal jacket. This created an oxygen deficient atmosphere (less than 19.5 percent oxygen). The nitrogen supply was isolated. And the room was evacuated. The alert was declared in accordance with Emergency Action Level (EAL) "hazard alert #7 (HA7)." Additional ventilation was being placed in the area to restore normal oxygen levels.

EAL table entry HA7 is for "Release of toxic or flammable gases within or restricting access to a vital area which jeopardizes operation of systems required to maintain safe operations or establish or maintain safe shutdown."

No personnel injuries occurred. Oxygen levels were returned to acceptable levels at 0933 CST.

The licensee notified the NRC Resident Inspector.

* * * UPDATE AT 1205 ON 11/27/2007 FROM PAUL CANTWELL TO MARK ABRAMOVITZ * * *

The ALERT was terminated at 1103 CST.

Notified IRD (McDermott), R3DO (Lipa), DHS SWO (Mary Anne), FEMA (Dan Sullivan), DOE (Anthony Parsons), EPA (Ms Ross), USDA (Andrew Watts), and USDA (Rick Turner).
