Oyster Creek Generating Station Radiation Protection Calculation RP-OC-1001-09-005 Page 1 of 5 I. Subject Disposition of Soil from Condensate Storage Transfer Pump House Excavation II. Objective Document the rationale used for the decision to re-use the approximately 225 cubic yards of soil that was excavated as part of the pipe repair to mitigate the leakage of tritium to the environment under the condensate storage transfer pump house.Ill. Summary Micro-R meter results were equal to background (10 jiRem/hr), and direct frisk results were all< 100 ccpm (corrected counts per minute). Twenty soil samples were taken at various depths as the excavation progressed.

All sample gamma isotopic results showed either Natural Products, or a combination of Natural Products and Cesium 137 (Cs-137), Cobalt 60 (Co-60), or Xenon 135 (Xe-1 35). (References C and D) Based on the analysis of these results, it was determined that the soil could be returned to the excavation site from which it came.IV.

Sample Counting All soil samples were counted as flowable solids (Reference A) to meet the Offsite Dose Calculation Manual (ODCM) environmental Lower Limit of Detection (LLDs) for sediment (Reference B). A mean count time of 1736 seconds and a median count time of 1448 seconds was needed to meet the Cs-134 and Cs-137 LLDs shown in the table below.Isotope LLD pCi/Kg LLD pCi/g Cs- 134 150 0.15 Cs- 137 180 0.18 NOTE: Flowable solids are defined as material considered to be "free-flowing" in nature, including liquids, solids, sand, crushed asphalt and concrete, or oils that (as an aggregate) require a container to retain its shape in appropriate sample containers.

VI. Sample Evaluation During 1991 Oyster Creek experienced a leak from the Condensate Storage Tank (CST), which resulted in contamination of the soil surrounding the tank. This event was documented under the requirements of 50 CFR 75(g). No sample data was available from 1991, however, soil samples were taken'04/09/01 from the area around the CST, with the following results: Natural Products K-40 Pb-212 Bi-214 Pb-214 Co-60 2.88E-6 to 8.1 E-5 gCi/g (or 2.88 to 81 pCi/g)Cs-137 2.21 E-7 gtCi/g (or 0.221 pCi/g)Cobalt 60 Co-60 has a radiological half-life of 5.27 years. As shown by the graph below, the Co-60 found in 2009 falls into the range expected (+ / -2 standard deviations (a)) from the decay of the Co-60 seen eight (8) years ago in soil taken from approximately the same location.

The median value from the range (2.88 to 81 pCi/g) found in 2001 was used (42 pCi/g) for the decay correction.

The average activity found in the 2009 samples ranged from 0.07 to 0.23 pCi/g, compared to the decay corrected result of 0. 18 pCi/g from the 2001 sample. The 2009 Cs-137 data is consistent with the expected results. These results are also consistent with documented amounts of Cs-1 37 found as part of ambient background.(See Appendix A)Xenon-135 Xe-135 is a noble gas fission product having a radiological half-life of 9.1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. In Oyster Creek's steam-water cycle, steam containing various radionuclides passes from the reactor pressure vessel through the various turbine stages, and after condensing becomes condensate.

This condensate is pumped to the condensate demineralizers where impurities, including radionuclides are removed. Almost all fission products are removed by the condensate demineralizers, and therefore they are not normally seen in the CST samples.However, tritium and noble gases are not removed in the condensate demineralizers..While the condensate demineralizers do not remove noble gases, the steam-jet air ejectors (SJAE's) do remove most noble gases and other non-condensable gases prior to the condensate demineralizers.

However, the SJAE's are not 100% efficient at removing all the noble gases.in the steam-water cycle, downstream of the condensate demineralizers, the condensate can be directed to either feedwater or the CST.Since Januaryl, 2009 Xe-1 35 has been found in the CST water three times in 23 samples.,ince the soil samples were removed from the excavation site of the leak while the leak was a:ctive. it is not unexpected to see Xe- 135 that was entrained in the CST water and:,bsequernily nrcorporated into the soil. Due to the short half-life, .*ny Xe- 135 in the soil has:ow decayed away.

Conclusion Based on the survey and sample results, the soil can be returned to the excavation site from which it came. All survey results (direct frisk and micro-R meter) were "Non Detected (ND)" above background.

All sample gamma isotopic results showed either Natural Products, or a combination of Natural Products and Cs-1 37, Co-60, or Xe-i 35. Based on the analysis of these results, it was determined that the soil could be returned to the original site.VIII. References A. CY-OC-130-511, Isotopic Analysis for Volumetric Waste Samples B.

Oyster Creek Generating Station Radiation Protection Calculation RP-OC-1 001-09-005 Page 5 of 5 Appendix A Background Cesium 137 During January 2007, a report was prepared that evaluated soil and vegetation sample results from the Finninger Farm property.

Significantly, this report described measured Cs-137 from New Jersey and property adjacent to the Oyster Creek site itself: "...,in the year 2000, as part of the confirmatory release survey for the adjacent Forked River site to the west of OCGS, the NRC reported that the maximum observed soil concentration of 0.53 pCi/g was not distinguishable from the variation in Cs-1 37 in the environment due to these fallout sources.The NRC also reported background Cs-1 37 concentrations in New Jersey' coastal plain soils as high as 1.5 and 2.8 pCi/g. In addition, decay-corrected historic REMP data from a predominantly upwind location, nearly four miles from the OCGS, yields present-day Cs-i 37 concentrations ranging from 0.862 to 1.68 pCi/g." The highest reported sample re~itf i2'pCi/g is well below all of these numbers.Additionally, a cesium background report was prepared February/March 2007 in order to support the above environmental project at the Oyster Creek site. The report described measured Cs-137 data from the New York area: "Following the Chernobyl event, Environmental Measurements Laboratory (EML) began a series of measurements on Long Island, NY. Post Chernobyl, EML reported 600 pCi/kg -3,200 pCi/kg {of Cs-1 371 in surface soils on Long Island, near Oyster Bay, after decay correction, this represents about 60 to 1800 pCi/kg (0 -5 cm) {depth} after decay to the present." This translates to 0.06 to 1.8 pCi/g.
