Condition/Problem Statement: Contamination found on pavement outside contamination area at Torus Water Storage Tank (TWST). Contamination was inside radiological area posted Radiation Area/Radioactive Material Area (RA/RMA). Condition was found during demobilization of area while taking down the containment tent at the TWST manway.

Statement of Cause: Sludge from the tank was placed into drums inside the containment tent at the manway. Due to rain and the front entrance to the tent not being sealed, water entered the tent, and some of the sludge on the herculited containment tent floor migrated through a failed seam and found its way outside the containment tent onto the pavement.

Extent of Condition: Contamination was contained to a small 0.5 ft2 area.

This area was immediately deconned and survey CAA-07-06888 was done and no conlamination was found in adjacent areas inside and outside the posted RA/RMA. No other containment tents are currently in use in the plant and the area at the TWST was demobed and down posted to an RMA at the TWST Page 3 of, 5

10/10/07 - KB - returned by MRC to incorporate comments Comments / Discussion:

The major concerns with this evolution are the potential to have an unmonitored release or a spill of radioactive material to the environment. This is a very low dose evolution. Due diligence by the work group and Rad Protection is required to avoid any unmonitored releases or spills of radioactive material to the environment.
