The assessment program collects information from inspections and performance indicators (PIs) in order to enable the agency to arrive at objective conclusions about the licensee's safety performance. Based on this assessment information, the NRC determines the appropriate level of agency response, including supplemental inspection and pertinent regulatory actions ranging from management meetings up to and including orders for plant shutdown. The Action Matrix Summary listed below reflects overall plant performance and is updated regularly to reflect inputs from the most recent performance indicators and inspection findings. Security information is not publicly available and the associated performance indicators and inspection findings are not integrated into the Action Matrix Summary.
For those plants that are in the regulatory response column, degraded cornerstone column, multiple/repetitive degraded cornerstone column, and unacceptable performance column of the Action Matrix, notes are provided to explain the assessment inputs that direct the associated regulatory response. Additionally, information on the current level of inspection at each reactor unit (based on deviations from the Action Matrix, supplemental inspection status, etc.) is also found below with each site. For any licensee in the Licensee Response Column, the expected agency inspection is the baseline program.
The substantive cross-cutting issues are available on the ROP Substantive Cross Cutting Issues Summary page for each of the plants.

| Ginna | Baseline Inspection and An IP 95002 supplemental inspection for the WHITE finding and PI will be performed. |
Degraded Cornerstone Column Ginna transitioned into the Degraded Cornerstone Column due to one WHITE finding in the Mitigating Systems Cornerstone originating in 1Q2009 and one WHITE Performance Indicator (PI) in the Mitigating Systems Cornerstone originating in 3Q2009. The WHITE finding was related to inadequate implementation of the preventative maintenance program for the turbine-driven auxiliary feedwater pump governor that led to a failure of the pump to operate properly during a surveillance test. The WHITE PI was related to exceeding the limit for Heat Removal Systems reliability. |

| Indian Point 2 | Baseline Inspection On December 16, 2008, the EDO approved the deviation memo to continue to provide heightened oversight for Indian Point Units 2 and 3 through calendar year 2009 because some exit criteria in the prior deviation related to ground water monitoring have not been met and the unique factors warranting a deviation from the ROP continue in 2009. This deviation is reduced in scope from prior years because the exit criteria related to the replacement alert and notification system have been met and the ROP is appropriate and sufficient to monitor performance in this regard. |
