.-. Coordinating Government Agencies Federal:* US Environmental Protection Agency (EPA)* US Geological Survey (USGS)New York State:* Department of Environmental Conservation (DEC)* Department of Public Health (DPH)Purpose Evaluate Entergy's performance and provide status of inspection findings associated with the following:
-Cause of the groundwater contamination
-Extent and migration of the groundwater releases-Radiological significance of these releases Ensure that public health and safety and protection of the environment were maintained
.Purpose* Ensure Entergy's groundwater transport model is correct and tested* Research prior opportunities for leak discovery and evaluate Entergy's response* Determine Entergy's conformance with regulatory requirements 1
.Scope" Assess Entergy's investigation of the Unit 2 spent fuel pool leak since August 2005* Examine Entergy's investigation of previous Unit 1 and Unit 2 spent fuel pool leaks identified in 1992 Scop* Independent Assessment Effort:-Collection and analysis of groundwater samples-Verification of licensee's hydrological conclusions
-Verification of dose assessment to the public-Verification of water inventory losses from Unit 1 and Unit 2 spent fuel pools-Verification of no detectable environmental impact through the analysis of aquatic food samples from the Hudson River. E e" -Scope* Comprehensive assessment of groundwater transport pathways and contaminant plume behavior* Historical conditions NRC Assessment

is limited to the Hudson River* The groundwater transport model was based on well-developed data, measurements, and field observations ,NRC Assessment During site visits and teleconferences, questions posed:> to evaluate the Conceptual Site Model assumptions, and> to pro-actively engage Licensee's contractor in developing corroborating field data> to understand ground-water plume sources,* extent, and behavior... NRC Inspection Focus and Activities
- NRC Staff from Region I and Office of Nuclear Regulatory Research provided technical oversight of IPEC ground-water contamination studies* U.S. Geological Survey scientist provided technical support to the technical oversight Initial ground-water contamination identified in leak from Unit 2 Spenl uel Pool Site visits focused on technical questions concerning the contaminant sources, pathways.
potential receptors.
and monitoring to detect future leaks Field data from rock cores, monitoring wells, geophysical surveys, hydraulic tests and tracer tests independently reviewed 2 NRC Assessment Questions What are the source(s) of the ground-water contamination?
Where do they intersect the accessible environment?
Are there fast and preferential pathways?Do the contaminant plumes move under the Hudson River?Are local drinking water sources affected?Are the plumes captured by the Discharge Canal?* What are the hydraulic controls on theplume(s)'
behavior as reflected in the Conceptual Site Model.* What remediation is appropriate?
- How can future leaks be detected?* What surveillance is needed to confirm dose assessments remain below regulatory limits?NRC Assessment Fundamental Understanding for the Conceptual Site Model* Nature of the leaks and initial pathways through backfills and fractured rock at or above the local water table.* Role of fractures and possibility of solutioning
& connectivity
- Interaction of ground-water flow with the Hudson River* Location and relationships to tocai drinking water sources -* Ground-water flow gradients, vertical and horizontal flow directions related to the sources. Discharge Canal, and River* Movement of H-3, Sr-90. Cs-137 and Ni-63 to the River* Benefits of a long-term ground-water monitoring program NRC Assessment Conclusions Unit 1 and 2 are the source(s) of the ground-water contamination
' Plumes move west, intersect the Hudson River but not under to Rockland County* Backfills and connected Iractures are the preferential pathways* No local drinking water sources are affected* Discharge Canal captures some but not all of the plume* Ground-water gradient and flow direction controlled by local hydrology* Monitored natural attenuation is the appropriate remediation approach* Future leaks can be detected by monitoring wells near Units 1 and 2 L Lg-ter monitoring is needed to confirm dose assessments remain bel regulatory limits during plant operations NRC Assessment Entergy implemented timely actions to investigate source, and determine dose impact Entergy conformed to regulatory survey requirements with 1 minor violation.
of quality control of sample analyses Groundwater contamination resulted only from leakage attributed to Unit 1 and Unit 2 Entergy's site characterization was based on state-of-the-practice monitoring wells, tests, and analysis methods M-"NRC Assessment" Exposure pathway to man is aquatic food from Hudson River (fish, invertebrates)" Calculated exposure to maximum exposed individual is 0.002 mrem/yr total body and 0.01 mrem/yr maximum organ" Calculated exposures are less than 0.1%of NRC regulatory limit Radiation Dose Perspective

- Entergy is monitoring and reporting the groundwater effluent release condition in accordance with NRC regulations
- Relative to Unit 1, there was no condition in which the licensee failed to meet a regulatory requirement or standard that was reasonably within its ability to detect or correct NRC Assessment
- Removal of Unit 1 fuel and drainage of the pools will eliminate the source of Sr-90, Ni-63, Cs-137* Entergy has initiated a long-term monitoring process to:-Report groundwater liquid releases-Measure the effectiveness of remediation and natural attenuation
-Detect new or changing groundwater contamination conditions NRC Lessons-Learned NRC Lessons Learned Task Force Identified:
-No regulatory guidance for detecting, evaluating, and.monitoring releases via unmonitored pathways-No regulatory requirement
/ guidance for remediation of groundwater conditions
-No requirement to assure leaks and spills will be detected before migration off-site Actions have been initiated to address these and other identified issues.-.- .Planned and Continuing NRC Inspection and Assessment
- Assessment of Long-Term Groundwater Monitoring Plan* Inspection oversight of Unit I fuel removal and pool draining activities
- Baseline inspection now includes aspects of groundwater protection and assessment
