Palo Verde provides the following response: Current procedural guidance requires that if the in-progress reviews should be used to evaluate / adjust dose estimates including electronic dosimeter setpoints (up or down) to ensure that they remain accurate and challenging. These modifications are required to be included in outage ALARA reports a s lessons learned. Palo Verde is also refining this process by modifying the RWP procedure to examine the efficacy of electronic dosimeter setpoints if current radiological survey data differs from expected (historical conditions) and by developing metrics to identify, track, and trend specific events to identify areas for improvement in radiological work planning such as quantifying the overall frequency of accumulative and rate alarms, identifying unique tasks or work areas that are experiencing these alarms, and adjusting RWP alarm setpoints as needed.

Does anybody have a process where they would adjust these established setpoints once the unit is off-line, and initial surveys are completed, dependent on conditions identified? David A.
