| Title | Changes to Duane Arnold Energy Center Action Level Notification Form, Note-05 |
| Description | The inspector reviewed changes made to the form used to notify state and local counties of an emergency event classification and other event related information such as meteorological data, release status, and protective action recommendations. The changes implemented to the Duane Arnold Energy Center Action Level Notification Form, Note-05, were reviewed for a potential decrease in effectiveness of the notification information provided offsite agencies relative to event related release-in-progress information. The licensee made several changes to the notification form to eliminate confusion for the operating crew on the determination of a release status during a classifiable event. One of the changes included the term release which was changed to abnormal release. The term release in progress on the original version was defined as a release occurring due to the event. On the changed version, abnormal release in progress was defined by the radiation monitor, i.e., KAMAN, reaching the KAMAN high alarm set point. Another change to the form was on the original version, the KAMAN high alarm indicated the release due to the event was at or above federal limits. On the changed version of the form, the KAMAN high-high alarm indicated the release was at or above federal limit. Another change made to the notification process was on the original notification form, the operators would determine if a release was occurring related to the event and then would quantify the release as either below or at or above federal limits. On the changed version, the operators could determine a release to be occurring due to the event; however, the release would not be notified as a release until the radiation level became 50 times the normal level or if a field team reported radiation levels. Additional changes were made to the KAMAN alarm set pointnumeric values for both the high and high-high set points. The licensee has indicated the notification form changes would have no effect on the offsite agencies response since the values are very low and below the thresholds for offsite actions. The issue of concern was considered an Unresolved Item because more information is needed from the licensee to fully understand the changes and to determine if the changes to the notification form are decreases in effectiveness that would require prior NRC approval.
