191 ADP CR3, LLC 15760 West Power Line Street I Crystal River, FL 34428 I. Introduction This position paper is for the classification of the land area for EOCZ-04. The Once-Through Steam Generators (OTSG's) building was classified as an MARSSIM Class 1 based on the RSCS HSA. NorthStar Radiation Protection department plans one of two options. 1) Free release and disposal of the OTSG building and pad, or 2) Disposal of the OTSG building and pad as Low-Level Waste (LLW) to WCS. The land area in Survey Unit EOCZ-04 is being classified as a MARSSIM Class 2 based upon the following discussion in this position paper. This is an evaluation of the 2016 and 2017 Mausoleum Building Soil Survey Data that contains both pre-remediation and post-remediation surveys, as well as sample data analysis. Additional characterization data will be obtained of the soil beneath the OTSG building once it is removed to determine if the MARSSIM classification needs to be upgraded. II. Overview The old once-through steam generators (OTSG's) and old reactor head were shipped out of the mausoleum building at the end of 2016 while CR3 was in SAFSTOR. During preparation for shipment, contamination was detected during routine surveys, both inside and immediately outside the mausoleum. Decontamination was subsequently performed to meet free release conditions as specified in plant procedure HPP-202A. The decontamination included scabbling concrete from the concrete surface inside the building and removal of surface soil immediately outside of the building where trace levels of contamination were detected. Ill. Survey Data Evaluation of Soil Samples Collected in EOCZ-04 The following four RP surveys show the as-found and as-left conditions of soil immediately outside of the building where contamination was found. It is noted that no hard-to-detect radionuclide analyses was performed during these surveys. Based on current industry guidance, such as in MARSSIM Section N.4, all reported concentrations greater than zero, even concentrations that are not considered statistically positive at the 95% confidence interval, were included in the Sum-Of-Fractions (SOF) calculations. Additionally, negative values were treated as zeros. Survey and Sample analysis are shown in Attachment A, B, C, and D respectively. Survey 16-10-0211: Performed October 31st, 2016. A total of 11 soil samples were collected outside the building, west and south. All showed Cs-137, ranging from 6.49E-2 pCi/g to 3.19 pCi/g. Of these 11 samples, three also showed Co-60, ranging from 1.21E-1 pCi/g to a high of 4.76E-1 pCi/g. No other easy to detect radionuclides were detected. It should be noted that sample 31-Oct-2016-0009 with an activity of 4.76E-1 pCi/g and 3.19 pCi/g for Co-60 and Cs-137 respectively was of sweepings on the concrete apron and not in the soil surrounding the building. See sample analysis results below in Table 1 and summary data in Table 2. Classification Position Paper of Survey Unit EOCZ-04 Page 2 of 187 3F1025-01 / Enclosure 10 / Page 2 of 187

191 ADP CR3, LLC 15760 West Power Line Street I Crystal River, FL 34428 Survey 16-11-0113: Performed November 4th, 2016. A total of 5 soil samples were collected on the north side of the building. None showed any licensed activity above MDA. The MDAs for Cs-137 and Co-60 were below 1.SE-1 pCi/g for each radionuclide. See sample analysis results below in Table 3 and summary data in Table 4. Survey 16-11-0186: Performed November 28th, 2016. A total of 6 soil samples were collected west of the mausoleum opening. Two showed Cs-137 at 1.16E-1 pCi/g and 1.25E-1 pCi/g, with no Co-60 detected above MDA. The other four samples did not show any easy-to-detect radionuclides above MDA. See sample analysis results below in Table 5 and summary data in Table 6. In early 2017, approximately 100-200 cubic yards of soil were removed immediately outside of the mausoleum building where trace contamination was found. The soil was disposed of as radwaste. The following post remediation survey was then performed: Survey 17-03-0104: Performed March 7th, 2017. A total of 8 soil samples were collected in front of the mausoleum building opening. All showed the absence of CR3 licensed material when counted to Cs-137 and Co-60 MDAs of 1.SE-1 pCi/g. See sample analysis results below in Table 7 and summary data in Table 8.

Summary The soil in EOCZ-04 where trace amounts of contamination was originally identified was successfully remediated for ALARA purposes. This data is being used to classify the land area survey unit EOCZ-04 for FSS as a MARSSIM Class 2 area as no concentrations of residual material exceeded the DCGLw either before or post the ALARA remediation. Additional as-found and as-left surveys were also performed inside of the building and showed free release criteria were met after decontamination as displayed in Attachment E. As stated, additional characterization data will be obtained of the soil beneath the OTSG building once it is removed to confirm the MARSSIM classification or upgraded to a Class 1 if required.
