011110 Omaha Pllblic Power District FC-020-007 Revision 0 Fort Calhoun Station Potential Radionuclides of Concern Page 3 of 29 1.0 ISSUE STATEMENT An initial listing of radionuclides is needed to support the decommissioning of Fort Calhoun Station. This listing will be specifically used to identify radionuclides applicable for calculating the derived concentration guideline levels (DCGLs) which are required for the license termination plan (LTP) to ultimately terminate the NRC operating license as delineated in 10 CFR 50.82 [1]. Once the DCGLs are calculated for each of the radionuclides in the initial suite, some may be deselected as Radionuclides of Concern (ROCs) based on a future dose-significance analysis for the implementation of the final status surveys which will also be required by the LTP.
2.0 BACKGROUND
STATEMENT In March 2018, the Fort Calhoun RP technical staff prepared Technical Basis Document (TBD) FC-18-002, "Potential Radionuclides of Concern During the Decommissioning of Fort Calhoun Station" [2]. This TBD evaluated expected radionuclides based on a review of industry guidance and from 14 samples collected within various waste/process streams from 2016 through 2018 analyzed by an offsite laboratory for nuclides typically required by 10CFR61, and decay-corrected to 2/15/2028. The list of radionuclides from FC-18-002 is reproduced in Table 1.
Table 1: List of Radionuclides from FC-18-002
/ Radionuclide I Half-Life, years I H-3 I 12.3 l Fe-55 I 2.73
' Co-60 I 5.27 Ni-63 I 100.1 Sr-90 28.74 Cs-134 I 2.07 Cs-137 I 30.04 Pu-238 I 87.7 Pu-239/240 24110 I Pu-241 14.35 Am-241 432.2 Cm-243/244 29.1 The analysis in FC-18-002 appears to have eliminated some of the radionuclides initially considered in the TBD based on fractional abundance and/or short half-lives. Also, the radionuclide fractional abundance listed in Attachment 1 of FC-18-002 appear to be intrinsically weighted by each sample activity whereas other prior LTPs have included fractional abundances using weighted and non-weighted approaches. From the data contained in this attachment, sample No. L71393 for the primary resin appears to dominate the activity from all other samples, therefore , using this data as presented

0111,10 Omaha Pllblic Power Ois11/ct FC-020-007 Revision 0 Fort Calhoun Station Potential Radionuclides of Concern Page 4 of 29 would unnecessarily numerically weight the radionuclide mixture by this single sample analysis.
From November 2019 through March 2020, the staff at Fort Calhoun station implemented a comprehensive concrete sampling and characterization plan where 744 discrete concrete samples at multiple depths up to 6 inches were collected throughout plant areas including the containment and the auxiliary buildings. Each of these samples were analyzed using the on site gamma spectroscopy system and 37 of these were sent for offsite laboratory analysis for a wide range of radionuclide detections including actinides, and other hard-to detect fission and activation radionuclides. The results of these 37 analyses are used in this TBD to evaluate whether additional radionuclides should be added or removed from the list provided in FC-018-002. With this list, DCGLs will be calculated for the applicable media and end-state of the site to be included in the site's LTP.
3.0 METHODOLOGY Provide the results of the offsite laboratory analysis for all radionuclides and for each of the 37 samples. This should determine those radionuclides that are considered non-detected and further determine the radionuclide fractional abundances for each of the 37 samples.
Analyze the radionuclide fractional results to identify those present in the sampled plant environments and compare this list to the initial listing from FC-018-002 and select the initial list for DCGL development.
4.0 ASSUMPTIONS The analysis of samples from the offsite laboratory meets the applicable quality standards as delineated by the laboratory.
The presence of radionuclides other than for the requested suite is insignificant or is otherwise added in this analysis.
5.0 CONCLUSION
S This analysis identifies 23 radionuclides that should be included in this listing of radionuclides as compared to the 12 that were initially identified in [2], as listed below, where the additional radionuclides are shaded. Additionally, it should be noted that the Europium isotopes are isolated to areas exposed to neutrons. For these, the data shows the presence of these isotopes is primarily in the area below the reactor vessel which is currently scheduled for removal and may not be an end-state structure. We also added Np-237 but we anticipate that this radionuclide may likely be removed in a future revision to this TSD following additional sampling and analysis since this was not included in the analysis suite from the recent characterization campaign.

- containment building,
- auxiliary building,
- turbine building, and
- radwaste processing building.
From this sample population, 37 samples were sent to GEL for analysis of the following gamma emitting, beta emitting, and alpha emitting radionuclides typically considered during nuclear power plant decommissioning projects.

Omaha Public Power Distlfd FC-020-007 Revision 0 Fort Calhoun Station Potential Radionuclides of Concern Page 6 of 29 Table 2 provides the sample identification numbers and general locations for all 37 samples. The analysis was performed by GEL Laboratories LLC in Charleston SC in 3 batches of reports in references [7], [8] and [9]. The original reports were prepared and sent from January through March 2020 and then revised in June 2020 to add the "critical level (Le)" to these reports for the analysis supported in this Technical Basis Document.
6.2 Sample Results Table 3 shows the average minimum detectable activity (MDA) from all 37 samples analyzed by GEL for each radionuclide. This listing demonstrates that an effective average MDA was achieved by GEL for the analysis.
Attachment 8.1 provides the analysis results for all samples. These results include all results as reported by GEL whether negative or less than any screening value including the minimum detectable activity (MDA).
To determine radionuclide fractions for each sample, the concentration data from Attachment 8.1 was first compared to the result to the reported critical level (for 95%
probability of detection). For those samples with results less than this criteria, a blank was substituted for the sample result as shown in Attachment 8.2. This data clearly shows that a large fraction of the samples did not detect some radionuclides above Le.
In fact, 2 radionuclides were only detected in 1 sample above Le among all samples:
Ag-11 Om and Cm-242 and will not be included for further consideration in this analysis.
Four additional radionuclides were detected at levels below twice the Le values but these will be included at this point in the analysis.

This information is summarized in Table 4. This summary provides the average, maximum, and 95 th percentile of the activity fractions among all sample for each radionuclide not excluded, as discussed above. The second to last column in this Table 4 is the re-normalized 95 th percentile values to represent an appropriate fractional value. For this analysis, radionuclides are deselected from the initial list if the renormalized fractional value is less than 0.0001 (0.01 %), except for the actinide radionuclides and consistent with [2]. The actinides are excluded from the 0.01 % criteria since the relative abundance for these radionuclides is typically lower and we therefore included all actinides that are positively detected above the Le. The last column in this table identifies whether the radionuclide is included in the final selection process.
