Title
10 CFR 20.1902 states, in part, that the licensee shall post each
high radiation area (defined as an area in excess of 100 millirem per hour at 30 centimeters) with a conspicuous sign or signs bearing the radiation symbol and the words Caution
High Radiation Area. Contrary to these regulations, on December 20, 2007, a radiation protection technician did not restore a
high radiation area posting for an area of the Unit 2
steam generators with general area dose rates as high as 250 millirem per hour at 30 centimeters. On December 23, 2008, two radiation protection technicians performing surveys in the area identified the incorrect
high radiation area posting and documented the issue in the licensees corrective action program as Action Request 071201417. The finding was determined to be of very low safety significance because it did not involve: (1)
ALARA planning and controls, (2) an
overexposure, (3) a
substantial potential for overexposure, or (4) an impaired ability to assess dose
