GGNS will report any MELLA+time-critical actions that are converted to"immediate actions" to the NRC Project Manager.The following are one-time actions which expire after the first report: The results of the three MELLA+time-critical operator actions training will be reported to the NRC Project Manager within 60 days of completion of the training.The reported results will include the full range of response times for each time-critical action and the average times for each crew.Any MELLA+time-critical operator training failures during evaluated scenarios will be reported to the NRC within 60 days of any failures with a plan for resolution.
