Dresden Station Radiological Groundwater Protection Program (RGPP) Status Report - 4 h Quarter 2007 To: Tmothy K. Hanley
~resdeny Plant Manager The purpose of this letter is to provide a status of the Dresden Radiological Groundwater Protection Program. There have been no new leaks or spills from contaminated systems that have impacted groundwater.
The RGPP provides information on groundwater movement and groundwater contamination. Trending of this data is helpful in predicting potential off-site dose and groundwater contamination consequences. The RGPP may, in some instances, identify a leak in a piping system. It is important to note that other leak detection methodologies such as pressure testing, the use of tracer gases, and G-Scan (guided-wave ultrasonic examinations) are better for leak detection. The most notable result from the 4 th quarter corporate sampling is the elevated tritium concentration found in the cooling pond. The previous three samples showed tritium concentrations at LLD. Tritium in the cooling pond was measured at 1,300 pCi/L in November of 2007. This tritium comes from Braidwood radwaste discharges.
Background:
The Dresden RGPP consists of two parts: (1) The corporate sponsored program consisting of groundwater samples taken every six months, and, the station's supplemental RGPP consisting of groundwater sampling once per month. Corporate RGPP: The corporate program samples 39 developed wells within the Protected Area (P.A.), 26 developed wells outside the P.A., and 6 surface water samples of the canals and cooling pond. Water levels are also taken to determine groundwater hydrology and trend groundwater movement. The sampling methodology follows a time consuming sampling standard where the wells are purged and the samples drawn at a slow rate. Samples are sent to an off-site lab and analyzed using a long count (2-hours) for improved Lower Level of Detectability (LLD). Supplemental RGPP: After identifying that the HPCI suction piping was leaking in 2004, the Dresden Chemistry groundwater-monitoring program was enhanced to include sentinel wells, sewers and trenches in the vicinity of this leak to assess changing conditions. The program continued to monitor other areas of historic leaks/spills and piping systems known to carry contaminated water. 'Tritium Maps' were developed to provide a tool to trend the analytical results. Grab samples are used to minimize the time required to collect the samples and analysis is performed in the counting room lab for 30 minutes. This is a flexible program that is also used to sample and analyze water from locations requested by different de artments as well as regulators. lC EVED

Corporate RGPP Results: Results are from samples taken in November of 2007. These results are included in the ODCM Annual Environmental Radiological Operating Report (AEROR) submitted to the NRC. Trends of the results are provided in Attachment 1. The results of the 39 samples taken from within the P.A. show about 2/3rds of the wells have measurable tritium contamination. The contaminated groundwater is located in areas of historic leaks and/or spills that have occurred over the last 40 years of operation. The wells outside the P.A. form a ring around the site. In general, the results of these samples show no measurable tritium contamination with the exception of the well near the radwaste discharge line and the wells near the hot canal. Supplemental RGPP Results: Results are from samples taken in January of 2008. Trends of the results are provided in Attachment 2. There are no significant changes in this data. Specific Results:
- 1. Cribhouse Electrical Penetration:
On September 3 rd, 2007, following heavy rains; water started flowing into the Cribhouse basement through one electrical penetration. Samples of this water showed an elevated tritium concentration. The tritium concentration increased over the next few days suggesting a leak in a nearby piping system. Further monitoring showed the tritium concentration and the flow dropping off (indicative of groundwater in-leakage that had picked tip tritium from a historic spill). CRA and Associates, an independent environmental consultant, was asked to evaluate this situation. CRA is suggesting additional groundwater monitoring wells to help quantify the local conditions (IR 668190 & 732919).
- 2. HRSS Ventilation duct On October 2 2 "d,2007, Water was found internal to the ductwork of an HRSS air conditioning unit. The water contained a measurable tritium concentration. An investigation identified that the most probable source of the contamination was a leaking valve on the HRSS hold tank. The water was transferred to a radwaste drain in the Unit 2 Turbine Building (IR 687732).
- 3. Sample Well DSP- 122 This sample well is located north of the Radwaste Tank farm. This well has showed a slowly increasing trend in tritium concentration. Chemistry continues to monitor this data.
- 4. Sample Well DSP-124 This well is just south of the Floor Drain Surge Tank south of the Unit 3 Reactor Building. This well shows a steady to increasing trend of tritium contamination. Chemistry continues to monitor this data (IR 619751).
- 5. Sample Wells MW-DN-124-S & I These wells are located just south of the liquid nitrogen tanks. They were installed to intercept the plume created by the leak of the 2004 HPCI suction piping. These wells show the highest concentration of tritium contamination on site (-100,000 pCi/L). For comparison, the tritium concentration in the 2/3 CST is about two orders of magnitude higher (-8,000,000 pCi/L). The concentration of tritium in these wells has been steady for the last year. Chemistry continues to monitor this data.
- 6. DSP-131 & DSP-132 The storm sewers on the Unit I side of the plant (east side) route through DSP-132 then discharge into the Unit Intake Canal. The sewers on the Unit 2/3 side of the plant (west side) route through DSP-13 1, then through an oil separator, then discharge into the Unit 2/3 Hot Canal. Results of samples taken from these storm sewers show trace amounts of tritium contamination, usually after a heavy rain. Chemistry continues to monitor this data.
- 7. Unit 2/3 Electrical Cable Tunnel There is groundwater leaking into the Unit 2/3 electrical cable tunnel. RP has mopped up this groundwater from time to time. The water shows measurable tritium whose source is unknown.
The tritium could be coming from the groundwater leaking in or from the plugged drain line that connects to radwaste. Engineering has determined that groundwater is leaking into the building rather than the water in the cable tunnel leaking out; therefore, there is low risk of contaminating groundwater from this source (IR 732915).
- 8. Condensate Pump Room From time to time there have been discoveries of standing water in the condensate pump room.
If there is tritium in the water the most probable source is leakage from the Condensate/Condensate Booster pumps. The water in this room routes to a sump that routes to radwaste. Engineering has determined that groundwater is leaking into the building rather than the water in the Condensate Pump Room leaking out; therefore, there is low risk of contaminating groundwater from this source.
