Groundwater Investigation
'06 Quarter 4 Activities and Results
- We continued to install new monitoring wells as Phase 2A of the program to test the groundwater under the site including four wells on the waterfront along the Unit 1 and Unit 2 Turbine buildings. We have a total of 3 5 new wells on site. This phase of the project is complete. Well sampling is ongoing.
Demineralizer Results:
The latest sample results The Unit 1 spent fuel pool demineralizer system from the down gradient wells (MW-49 and MW-removed about 98% of the Sr-90 activity in the pool.
- 50) have shown a 5-10 fold reduction in Sr-90 levels.
- Radiological Environmental Monitoring Program fish
'06 Fall Fish Samples samples obtained from the Hudson River came back obtained from the Hudson non-detectable for Sr-90 for the spring of '06.
River 20 -25 miles north of Indian Point collected for IPEC are showing low levels of Sr-90. Samples collected by the NRC are showing no levels and DEC results have not been returned We believe our findings are background readings.
- Entergy and the Indian Point Energy Center hosted an open house to present information about the A similar event was held ongoing groundwater investigation activities on for the Nuclear Thursday, October 5 between 4 -8 p.m. Experts on Committee of Entergy's Board of Directors on the groundwater investigation, radiation health October 17 effects and high resolution video inspection were available to explain the program and answer questions.
- Remediation Pilot Test: The groundwater investigation team conducted a pump test to determine if a recovery well, could be used to hydraulically prevent the migration of tritiated groundwater around the Unit 2 Fuel Building. The I PEC00063899
test is also designed to test the feasibility of pumping groundwater from the area near IP2. The RW-1, located in the Unit test did indicate that water could be drawn from 2 Fuel Storage Building around Unit 2 without drawing Sr-90 contaminated (FSB) water from Unit 1. The RW-I well pumping did influence water in the Unit 2 Transformer Yard (MW-34) as expected. Sampling from the monitoring wells has resumed.
- The leak collection box installed at the Unit 2 spent fuel pool continues to show essentially no water coming from the crack on the southwest wall. In December 375 ml of water was collected in 4 weeks.
- As part of the investigation of structures and systems on site, the team has examined storm drains.
Inspection and cleaning is complete. Unit 1 drain system has spread contamination to the Unit 3 site.
- The dye tracer tests, which are designed to help characterize flow direction and velocity near the Unit 1 and Unit 2 pools, will begin in early February 07.
- Entergy will begin non-destructive testing in February of the IP2 spent fuel pool transfer canal to determine if any areas identified on the video inspection are potential through-wall leaks I PEC00063900
