Attachment I 2005 Annual Radioactive Effluent Releases Report for SNEC E9 10-05-062 Summary of Radioactivc Liquid and Gaseous Effluents and Solid Waste Released from SNEC during 2005 There were no radioactive liquid or gaseous effluents released from SNEC during 2005.
There were no solid waste shipments that met the requirements as outlined in Reg. Guide 1.21, Rev. 1 released from SNEC during 2005.
2005 Annual Radioactive Effluent Releases Report for SNEC E9 10-05-062 Solid Waste Shipped Offsite During 2005 There were no solid waste shipments that met the reporting criteria.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-015 Summary of Unplanned Releases from the SNEC Facility Site During 2005 There were no unplanned releases to unrestricted areas from SNEC site during 2005.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-062 Changes to the Process Control Program and the Offsite Dose Calculation Manual during 2005, and a listing of new locations for dose calculations and/or environmental monitoring identified by the land use census
- 1. Changes to the Process Control Program There were no revisions to this program or procedure in 2005.
- 2. Changes to the Offsite Dose Calculation Manual during 2005 There were no revisions to this manual in 2005.
- 3. A listing of newt locations for dose calculations and/or environmental monitoring identified by the land use census Per the SNEC ODCM Section 2.3.2 broad leaf vegetation was collected and analyzed for gamma-emitting radionuclides in lieu of performing a land use census. Therefore, no new environmental monitoring locations were identified.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-062 Instrumentation not returned to operable status wiithin 30 days during 2005 RMA-1 was shut down in October 2003. In 2004, it was permanently removed from service as permitted by Licensing Amendment 19 dated January 9, 2004.
During 2005, there were no activities that had the potential to cause a MEASURABLE RELASE to the environment. Therefore, there were no requirements for monitoring or instrumentation thus there was no instrumentation not returned to operable status within 30 days per the SNEC ODCM Part 1, Control 2.1.2.b.
2005 Annual Radioactive Effluent Releases Report for SNEC E9 10-05-062 Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from SNEC during 2005 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2005 SNEC releases of gaseous and liquid effluents.
Provided below is a brief explanation of the table.
A. Liquid (Individual)
SNEC released no liquid effluents in 2005.
B. Gaseous (Individual)
There were no noble gases released from SNEC during 2005, the gamma and beta air doses were zero.
There were no particulate or tritium gaseous releases from SNEC during 2005.
Therefore, the maximum organ dose due to the release of particulates and tritium from SNEC in 2005 was zero to the liver, total body, thyroid, kidney, lung and GI tract of a child residing 200 meters from the site in the N sector.
Note: In accordance with SNEC ODCM, four major pathways are considered in the dose calculations for SNEC gaseous effluents. These were: (1) individual inhalation of airborne nuclides (2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man (3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and (4) deposition on the ground with subsequent exposure of man. In lieu of real time meteorology, the highest average gaseous dispersion factor was used in all dose calculations for gaseous effluents.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-062 C. Liquid and Gaseous (Population)
SNEC released no liquid or gaseous effluents in 2005. Therefore, the dose was calculated to be zero. These doses were summed over all pathways and the affected populations.
Note: The person-rem doses from gaseous effluents were based upon the population estimate and age distribution assumed in the analysis provided in GPU Nuclear letter to the Commissioners 6L20-98-20105 (Docket No. 50-146). Consistent with this analysis, dose calculations were not performed beyond 10 miles as specific population data is not easily available and releases from the site are considered to be at ground level. As a result, releases of particulates beyond 10 miles will be insignificant since it is assumed diffusion and wet and dry deposition beyond 10 miles will deplete the plume before it reaches 10 miles.
Additionally, since the plant has been shut down for so long and all spent fuel has been removed from the site, iodines and noble gases no longer exist.
SNEC gaseous effluents resulted in a whole body population dose of zero person-rem.
For 2005, SNEC liquid and gaseous effluents were estimated to be zero well below the maximum hypothetical doses of the quarterly and yearly 10 CFR 50 Appendix I limits.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-062 Assessment of Radiation Doses from Liquid and Gascous Effluents Releases to Members of the Public within the SNEC Facility Site Boundaries during 2005 The Offsite Dose Calculation Manual requires an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of public due to their activities inside the site boundary during the reporting period. The public did not have unrestricted access to the SNEC site during 2005. Therefore, no assessment of this dose is applicable.
2005 Annual Radioactive Effluent Releases Report for SNEC E910-05-062 Assessment of Radiation Dose to Most Likely Exposed Real Individual pcr 40 CFR 190 Dose calculations were also performed to demonstrate compliance with 40 CFR 190 (ODCM Part II Section 6). Gaseous and liquid effluents released from SNEC in 2005 would have resulted in maximum individual doses (regardless of age group) of zero mrem to any organ including the whole body. The direct radiation component was determined using the highest 2005 fence line exposure rate as measured by a TLD and subtracting from it the lowest TLD exposure rate. This method more accurately determines the exposure from SNEC by subtracting out the exposure rate from other sources of radiation in the environment. Based on the maximum exposure rate of 6.10E+00 mrem/standard-month, a person residing at the fenceline for 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> (shoreline exposure from Reg.
Guide 1.109) would have received an exposure of 5.60E-01 mrem. Based on the lowest exposure rate of 3.30E+00 mrem/standard-month and converting it by the same method gives a background exposure of 3.03E-OlmR. Therefore, the net exposure from direct radiation from SNEC is 2.57E-01 mrem. Combining the direct radiation exposure (assumed to be equal to dose) with the maximum organ doses from liquid and gaseous releases (no releases; assumed zero dose), the maximum potential (total) dose would have been 2.57E-Olmrem to any organ. Both dose assessments are well below the limits specified in 40 CFR 190.
