ROP Action Matrix Summary and Current Regulatory Oversight

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.

Calvert Cliffs 1	Baseline Inspection	Licensee Response Column
Calvert Cliffs 2	Baseline Inspection	Licensee Response Column
FitzPatrick	Baseline Inspection	Licensee Response Column
Ginna	Baseline Inspection and An IP 95002 supplemental inspection will be performed.	Degraded Cornerstone Column Ginna is in the Degraded Cornerstone Column due to two White findings in the Mitigating Systems Cornerstone (one originating in 1Q2009, and one originating in 4Q2009), and one White Performance Indicator (PI) in the Mitigating Systems Cornerstone originating in 3Q2009. The 1Q2009 White finding was related to inadequate implementation of the preventative maintenance program for the turbine-driven auxiliary feedwater (TDAFW) pump governor that led to a failure of the pump to operate properly during a surveillance test. The 4Q2009 White finding was related to inadequate corrective actions to prevent recurrence of corrosion which led to binding of the governor control valve and failure of the TDAFW pump. The White PI was related to exceeding the limit for Heat Removal Systems reliability.
Hope Creek 1	Baseline Inspection	Licensee Response Column
Indian Point 2	Baseline Inspection	Licensee Response Column
Indian Point 3	Baseline Inspection and An IP 95001 supplemental inspection will be performed.	Regulatory Response Column Indian Point Unit 3 is in the Regulatory Response Column due to one White Performance Indicator (PI) in the Initiating Events Cornerstone originating in 3Q2009. The White PI was related to exceeding the limit for Unplanned Scrams per 7000 Critical Hours.
Limerick 1	Baseline Inspection	Licensee Response Column
Limerick 2	Baseline Inspection	Licensee Response Column
Millstone 2	Baseline Inspection	Licensee Response Column
Millstone 3	Baseline Inspection	Licensee Response Column
Nine Mile Point 1	Baseline Inspection	Licensee Response Column
Nine Mile Point 2	Baseline Inspection and An IP 95001 supplemental inspection will be performed.	Regulatory Response Column Nine Mile Point Unit 2 remained in the Regulatory Response Column due to one parallel White finding originating in 4Q2009. The White finding was associated with a previous White performance indicator (PI) in the Mitigating System cornerstone originating in 4Q2008 for Cooling Water System unavailability and reliability. The supplemental inspection for the White PI, completed on October 16, 2009, resulted in the parallel White finding based on NRC identified weaknesses in the licensee's root cause evaluation.
Oyster Creek	Baseline Inspection and An IP 95001 supplemental inspection will be performed.	Regulatory Response Column Oyster Creek is in the Regulatory Response Column due to one White Performance Indicator (PI) in the Initiating Events cornerstone originating in 3Q2009. The White PI was related to exceeding the limit for Unplanned Scrams per 7000 Critical Hours. The PI has reverted to Green, so Oyster Creek will remain in the Regulatory Response Column until the supplemental inspection is completely succesfully.

Salem 1	Baseline Inspection	Licensee Response Column
Salem 2	Baseline Inspection	Licensee Response Column
Seabrook 1	Baseline Inspection and An IP 95001 supplemental inspection will be performed.	Regulatory Response Column Seabrook is in the Regulatory Response Column due to one White finding in the Mitigating Systems Cornerstone. The final significance determination and follow-up assessment letter was issued on November 12, 2009, based upon an inspection completed in 3Q2009, and involved the failure to adequately control design changes implemented on the B Emergency Diesel Generator jacket water cooling system.
