| Title | Failure to Maintain Accurate Methods for Dose Assessment |
| Description | An apparent violation of 10 CFR 50.54(q)(2) was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency between September 2012 and November 2013, in accordance with the requirements of 10 CFR 50.47(b)(9). During an exercise conducted on November 13, 2012, the licensee identified that the Electronic Dose Calculation Program did not accurately calculate the consequences of a radiological release through the main vent stack with the effluent monitor in accident mode. The inaccurate calculation was corrected on February 25, 2014. The inspectors determined the failure to maintain a dose assessment process capable of providing a technically adequate estimate of offsite dose was a performance deficiency within the licensees control. This finding is more than minor because it was associated with the emergency response organization performance and the Facilities and Equipment cornerstone attributes. This finding was evaluated using the Emergency Preparedness Significance Determination Process and was preliminarily determined to be of low to moderate safety significance (White) because it was a degraded risk significant planning standard function. The planning standard function was degraded because between September 13, 2012, and November 8, 2013, some calculations used to assess the offsite consequences of a radiological release were inaccurate. This issue has been entered into the licensees corrective action system as Condition Report 2013-0076247. |
