| event text = On September 17, 2011, a root cause analysis identified that errors in the dose projection software gain factor associated with the high range stack monitor were introduced in 2000 and had the potential to produce inaccurate dose projection results. The resulting condition could have impacted the ability to accurately assess ongoing releases and determine appropriate protective measures for the public. The gain factors were corrected in October 2011 and dose projection capabilities have been restored. | | event text = On September 17, 2011, a root cause analysis identified that errors in the dose projection software gain factor associated with the high range stack monitor were introduced in 2000 and had the potential to produce inaccurate dose projection results.

This condition was not originally recognized as being reportable in accordance with 10 CFR 50.72(b)(3)(xiii) due to the limited nature of the impact to a small portion of the radiological effluent EALs, however, it has been recently determined to be reportable. This late identification of reportability has been entered into our corrective action program. | This condition was not originally recognized as being reportable in accordance with 10 CFR 50.72(b)(3)(xiii) due to the limited nature of the impact to a small portion of the radiological effluent EALs, however, it has been recently determined to be reportable.
