1. Purpose '

The purpose of this calculation is to document the most representative list of radionuclides to be considered at the SNEC facility and to provide verification why some radionuclides were selected and others were not.

Chapter 5, Table 5-1 of the SNEC License Termination Plan (LTP), Revision 0, contains a list of 26 radionuclides that have derived concentration guidelines (DCGLs) calculated. These radionuclides were identified as part of the site characterization process. This data was selected from the SNEC Characterization Report (Reference 3.1). To date more analytical information has been collected in justifying a better representation of radionuclides found at SNEC. In addition, a formal process, based on regulatory guidance, has been implemented to select radionuclides applicable to the site.

Determining a representative list of radionuclides provides the following:

a. Increased efficiencies and clearer guidance for sampling and analysis.

b. Emphasis on radionuclides contributing significant doses to the public.

c. More efficient regulatory review.

d. Simplification of dose models.

e. Analytical cost reduction.

2

2. Summary of results Guidance from NUREG/CR-3474 and NUREG/CR-0130 (References 3.6 & 3.7) was used to first develop a comprehensive list of radionuclides (Table 4) that could potentially be found in media at SNEC, during its operation and post shutdown periods. From this list various criteria was used to deselect radionuclides.

Information on site-specific radionuclides was also determined using results of characterization surveys, waste stream analyses and historical site assessments that are appropriate for each medium. Once a list was developed a 4-step process was used to deselect radionuclides that are not applicable to SNEC.

Step 1 - SNEC has been shut down for almost 30 years. All radionuclides with half lives less than 3 years have been deselected since they have decayed 10 half lives.

Step 2 - Over 500 samples in various media have been analyzed as part of the characterization process.

Radionuclide results below minimum detectable activity (MDA) levels were deselected.

Step 3 - Radionuclides in media that were < 1% of the total mix activity and < 10% of the dose limit were also deselected. Per Appendix E of NUREG-1727 (Reference 8) radionuclides contributing < 10%

of the dose limit can be screened out.

Step 4 - Evaluate which media contain certain radionuclides.

Assumptions and Basic Data The following criteria was used to determine a reasonable list of radionuclides that are significant at the SNEC site (Reference Table 3.4):

a. NUREG/CR- 0130 & 3474 guidance for selection of radionuclides in PWR station media. The following tables from these NUREGs were used to determine a comprehensive list of radionuclides from which a deselection process could be used, i.e. NUREG/CR-3474, Tables 1.1, 5.4 & 5.6 and NUREG/CR-0130, Volumes 1 & 2, Tables 7.3-5, 7.3-11, 7.3-14, C.1-3, C.1-5, E.2-1, E.2-2 & E.2-3.

This list is consistent with the regulatory guidance for radionuclides of concern in bio-shield wall concrete, rebar, and surface contamination and site deposition from radioactive releases. A total of 71 radionuclides initially made the comprehensive list as a result of the NUREG tables review and, also, through the addition of some transuranic nuclides not contained in the NUREG tables.

However, many radionuclides in the regulatory guidance are not applicable to SNEC based on short half-life, low relative abundance in media mix, or inconsequential dose contribution.

b. List, for possible deselection, radionuclides that have decayed 10 half lives (i.e. radionuclides with half-life < 3 years). This method takes into account SNEC's 30 year shut down period. A total of 31 radionuclides with half-lives less than 3 years were deselected from the initial list leaving 40 radionuclides remaining.

c. Evaluate positively identified radionuclides (i.e. gamnia emitters, hard to detect and transuranic nuclides) identified above MDA. Gamma scan results on over 540 samples were reviewed from the SNEC characterization electronic database. In addition, transuranic and hard to detect radionuclides were reviewed from technical reports and laboratory analysis data. Sample media consisted of smears, core bores, pipe scrapings, soil, sediment and water. Samples were obtained from CV system components & piping, structural concrete, surface & sub-surface soils, site wells, CV paint and SSGS related structures. A total of 21 radionuclides were deselected as being less than MDA leaving 19 radionuclides remaining. Of these 19, two radionuclides (Fe-55 & Cm-242) have half lives less than 3 years but were reported above MDA in a few samples. Since Cm-242 has decayed 67 half lives since the shutdown of SNEC (1972) an investigation was conducted to determine why this nuclide was being reported by the off site laboratory. It was determined that the Cm-242 was misidentified as a result of natural thorium daughter interference. Therefore, Cm-242 has been deselected. The Fe-55 is less than 1% of the mix activity and will be deselected (see Table 5).

Per Reference 3.11 one gram of natural uranium contains 0.33 uCi ofU-238, 0.015 uCi ofU-235 and 0.3 uCi of U-234, subject to minor variations in U-234. U-234, U-235 and U-238 have been detected in samples. Results of these uranium nuclides are listed in Table 2. An evaluation was made to determine if these uraniums were plant produced or naturally occurring. Table 3 presents W:/Donnachie/SNECNuclideListCalcForm.doc

d. Deselect radionuclides < 1% of media mix and < 10% of the dose limit per NUREG-1727, Appendix E. From the 19 radionuclides determined in Section C above, 7 radionuclides (Fe-55, Ni 59, Nb-94, Tc-99, Eu-I154, Pu-242, & Cm-244) were further deselected due to a low abundance (<

1%) in the media mixes. Deselection was based on review of the 1996 Site Characterization Report, SNEC License Termination Plan Table 2-1, most recent characterization analysis data and removal of contaminated plant equipment. In the 1996 Site Characterization Report, Table 4-1, Fe-55 was listed as 2.46% of the site's radionuclide inventory contained within the steel structures of the reactor vessel. In 1998 the reactor vessel was removed along with the steam generator and pressurizer as part of the Large Component Removal program. This program essentially reduced the Fe-55 to only 0.12% of the site radionuclide inventory per the 2000 LTP, Table 2-1.

Tables 5 and 6 provide information on how these radionuclides were also deselected based on contributing less than 10% of the total effective dose equivalent (total of external and internal). Dose conversion factors were taken from Federal Guidance Report (FGR) 11, Tables 2.1 (Exposure-to Dose Factors for Inhalation) and 2.2 (Exposure-to-Dose Factors for Ingestion) and FGR 12, Table 111-7 (Dose Coefficients for Exposure to Soil Contaminated to an Infinite Depth). Since all these radionuclides are < 1% of the mix and Cs-137 is the predominate radionuclide onsite, the applicable DCFs were normalized using the applicable nuclide-to-Cs ratio from either the SNEC LTP Table 2 1 or from Table 6 information. The normalized DCFs were then compared against applicable pathway Cs-137 DCF to determine if the respective doses would be greater than 10% of the Cs-137 dose. Since there is no external dose hazard from Fe-55 and Ni-63 there are no DCFs in FGR 12.

For gamma exposure the Cs-137 daughter (Ba-137m) contributes the entire dose. Therefore, the Ba 137m dose coefficient from FGR #12 Table 111-7 was used. FGR 11, Tables 2.1, 2.2 and 3 were used to calculate the committed effective dose equivalents from ingestion and inhalation for each radionuclide. Per Table 5, doses attributed individually to Fe-55, Ni-59, Nb-94, Tc-99, Eu-1 54, Pu 242, & Cm-244 are less than 10% of the Cs-137 dose and have all been deselected. This reduces the list to 11 radionuclides (H-3, C-14, Co-60, Ni-63, Sr-90, Cs-137, Eu-152, Pu-238, Pu-239, Pu-241 &

Am-241) considered to be significant dose contributors at the SNEC facility.

e. Evaluate locations where radionuclides have been identified on site and are most likely to occur (e.g.

inside or outside the CV). From review of the different types of media from Section C and Table 1, it can be shown that all 11 radionuclides have the potential to be present inside the CV. However, for media (e.g. soil, water, concrete, metal) outside the CV, the presence of these radionuclides can be further limited.

Conclusions 5.1 Based on the radionuclide deselection process, per the guidance in the subject NUREGs, the SNEC Radionuclide List Table in Section 2 lists the potential radionuclides of concern at SNEC. In addition, this is supported by recent characterization data that has been gathered from operational and decommissioning survey work over the last 5 years.

5.2 It is recommended that a total of eleven (11) radionuclides should be analyzed for all collected media and surveyed surfaces inside the CV. The revised radionuclide list should be updated into the next revision of the LTP. For media and surfaces surveyed in land areas and structures outside the CV it is recommended a review of the latest characterization data be used to select the applicable radionuclides of concern for the final site survey.

5.3 Per Table 5 of this analysis seven (7) nuclides have been deselected from the SNEC mix. These nuclides contribute a total of 3.45%, or 0.86 mrem, of the annual dose limit (25 mrem). This small dose will need to be accounted into the dose modeling of the site DCGLs.
