| Title | Failure to Control Access to a High Radiation Area with Dose Rates in Excess of 1.0 R/hr |
| Description | The inspector reviewed a self-revealing noncited violation of Technical Specification 6.7.2 for failure to control a high radiation area with dose rates in excess of 1.0 R/hr. On September 12, 2009, a radiological barrier was removed by a work crew exposing an area with dose rates in excess of 1.0 R/hr without radiation protection personnel authorization. Radiation protection personnel did not fully understand that the work crew was intending to remove the secondary handhole barrier on the Unit 2 steam generator A to clean the area in preparation for installing the strongback. The dose rate one foot within the handhole was 2.9 R/hr. Radiation protection was made aware of the situation when reviewing the cause for one member of the work crew receiving a dose rate alarm. The issue was documented as Condition Report ANO-2-2009-02609. The failure to control a high radiation area with dose rates in excess of 1.0 R/hr is a performance deficiency. The finding was greater than minor because it was associated with the Occupational Radiation Safety cornerstone attribute (exposure control) of program and process and affected the cornerstone objective, in that, the failure to properly control a high radiation area with dose rates in excess of 1.0 R/hr had the potential to increase personnel dose. This finding was evaluated using the Occupational Radiation Safety Significance Determination Process and determined to be of very low safety significance because it did not involve: (1) ALARA planning or work control issue, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Additionally, this finding had human performance crosscutting aspects associated with work control in that the work planning did not appropriately plan work activities by incorporating risk insights and radiological safety H.3(a) |
