| Title | Failure to Control Access to a High Radiation Area with Dose Rates in Excess of 1.0 Rem Per Hour |
| Description | The inspectors reviewed a self-revealing noncited violation of Technical Specification 5.7.2 for failure to control a high radiation area with dose rates in excess of 1.0 rem per hour. Specifically, on January 30, 2008, a worker, within the 512\' reactor traversing incore probe mezzanine room, received an electronic dosimeter alarm and the investigation survey found that Valve RFW-V-70 had a dose rate of 4.2 rem per hour on contact and 1.2 rem per hour at 30 centimeters. The area was immediately controlled as required per Technical Specifications. Review of this occurrence revealed surveys indicating an upward trend of radiation levels on the valve in the May and June 2007 time frame. The review also revealed that several crud burst causing evolutions occurred around the June to July 2007 time frame and there was no process in place for radiation protection to be informed so that they could adequately monitor for changing radiological conditions throughout the plant. The issue was entered into the licensees corrective action program as Action Report/Condition Report Numbers 00176887 and 00178189. Initial corrective actions included controlling the area as required by Technical Specifications and procedure changes to ensure radiation protection is notified of such evolutions and enhancement of radiation protection procedures to include additional areas of the plant to be monitored upon notification of crud burst causing evolutions. The failure to control a high radiation area with dose rates in excess of 1.0 rem per hour was a performance deficiency. This finding is greater than minor because it is associated with the occupational radiation safety program and process attribute and affected the cornerstone objective, in that the failure to properly control a high radiation area with dose rates in excess of 1.0 rem per hour 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) an as low as is reasonably achievable planning or work control issue, (2) an overexposure, (3) a substantial potential for overexposure, or (4) an impaired ability to assess dose. Additionally, the violation has a crosscutting aspect in the area of human performance associated with the work control component because of a lack of interdepartmental communication and the failure to keep radiation protection informed of evolutions that may cause a change in radiological conditions H.3(b) |
