EXECUTIVE
SUMMARY
The 2023 Zion Nuclear Power Station (Zion Station) Annual Radioactive Effluent Release Report (ARERR) is presented here. As a note, the Zion Station Operating License, that transitioned to a decommissioning license was terminated (upon completion of the Zion Station License Termination Plan LTP), by the Nuclear Regulatory Commission in August of 2023.
No liquid or gaseous effluents were released from Zion Station in 2023. However, as in 2022, some additional plant material consisting of analytical samples, small amounts of construction concrete, cores, iron, soil samples, plastic sample containers and wood were removed from storage and shipped to the Energy Solutions Low Level Radioactive Bulk Waste Facility in Clive Utah as detailed in Table A-3 Low Level Waste Section of this report. All of this 2023 material was declared waste upon termination of the Zion Station License in accordance with the License Termination Plan (LTP) approved in October of 2018 by the NRC, and the actual termination of the license by the NRC in August of 2023.
This low-level waste was shipped off site on 11/10/2023 by Hittman Transportation Services Inc. The total volume of waste shipped consisted of 2200.0 cubic feet, or 62.28 cubic meters of Dry Active Waste (DAW) shipped as Low Specific Activity (LSA-I) consisting of analytical samples containing 2.25 E+01 millicuries, or 2.25 E-02 Curies in total, of licensed material. The most significant radionuclide in the waste shipped was 1.37 E-02 Curies of Ni-63.
The only off-site dose reported for 2023 was the result of direct dose from radioactive material stored on site; principally spent nuclear fuel and Greater than Class C (GTCC) waste stored on the Independent Spent Fuel Storage Installation (ISFSI) facility. Total direct dose at the protected area boundary was 0.68 mrem in 2023 at location Z-131; see sector Q on Figure 1.1-A. This is the location on site where sky shine has historically had its most significant measured impact to a location accessible to a member of the public.
With average background levels subtracted, the annual dose to a member of the public was adjusted for occupancy resulting in the highest off-site dose to a member of the public being reported as 0.68 mrem after summing all four quarters in 2023.
Lastly, this result is finalized by ratioing it up for neutron exposure as a measure of conservatism when neutron dose is detected.
The highest neutron dose to gamma radiation ratio level identified was 14/56 +1.0 =
1.25. 1.25 x 0.68 mrem is the highest dose accessible to a member of the public. 0.68 mrem x 1.25 = 0.85 mrem of direct external dose to a member of the public in 2023. The 2nd Quarter of 2023 had the highest neutron to gamma ratio at ISFSI West.
Principal activities on-site in 2023 included shipping and confirmation surveys of the waste on-site, final site grading, performance of follow up final status surveys and additional sample collection with on-site and off-site analysis conducted under the sites License Termination Plan (LTP), Revision 2, approved by the NRC in October 2018.
2023 ZION NUCLEAR STATION ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (ARERR)
Zion Station 2023 ARERR Page 4 of 14 May 1, 2024 Decommissioning was completed in the 4th quarter of 2023 with the NRC approving termination of Zion Stations license.
- There were no liquid effluent or gaseous effluent releases in 2023.
- 2200 cubic feet, or 62.28 cubic meters, of DAW including poured concrete demolition material, and plant material consisting of analytical samples, small amounts of construction concrete debris, cores, iron, soil samples, plastic sample containers and wood EnergySolutions low level waste facility in Utah by Hittman Transport Services Inc. trucks to the BWF and Treatment Facilities.
II.
SUPPLEMENTAL INFORMATION
- 1.
Abnormal Releases and Abnormal Discharges (e.g., leaks and spills)
There were no Abnormal Releases or Abnormal Discharges (e.g., spills or leaks of radioactive material) during decommissioning in 2023.
- 2.
Non-routine, Planned Discharges (e.g., pumping of leaks and spills for remediation, results of ground water monitoring to quantify effluent releases to the offsite environment)
There were no non-routine, planned radioactive discharges for remediation resulting in releases off-site, and therefore, no resulting off-site impact.
- 3.
Offsite Dose Calculation Manual Changes There were no revisions to the Zion Station Off Site Dose Calculation Manual (ODCM).
- 4.
Errata/Corrections to Previous ARERRs There were no Errata/Corrections to previously issued ARERRs in 2023.
- 5.
Other (narrative description of other information provided to the U.S. Nuclear Regulatory Commission, e.g., the ARERR for ISFSIs)
- a. The ISFSI facility is located within the Zion Station Site and Controlled Area Boundaries. With all significant source term shipped off site, the ISFSI is the primary source of direct radiation exposure on site and to a member of the public in any unrestricted areas. The station boundary and owner-controlled boundary doses include the direct radiation component of the ISFSI.
The Zion Station decommissioning and Final Status Survey efforts proceeded under the 10 CFR 50 license guidance - ODCM. The ISFSI Facility is operated per its general license issued under 10 CFR 72. The determination of off-site public dose impact is identical for both licenses during this period until August of 2023 when the Part 50 license was terminated. Although the Part 50 ODCM methodology need not be followed post-termination of Part 50, it can continue to be utilized until the part 72 license-holder decides to simplify the off-site dose reporting process and documents these changes in a revision to the ODCM or equivalent reporting guidance.
2023 ZION NUCLEAR STATION ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (ARERR)
Zion Station 2023 ARERR Page 5 of 14 May 1, 2024 Direct dose was the only contributor of plant-related radiation exposure to a member of the public as shown in Table A-5 with projected whole-body dose of 0.85 mrem per year in 2023 or 3.4% of the annual 40 CFR 190 dose limit of 25 mrem/year measured 300 feet from the center of the ISFSI pad. This TLD is on the road leading to the ISFSI delivery gate, about 100 feet from the gate, and fully visible from the gate. This is the location where highest dose to a member of the public could be received and the expectation is that Security would keep this area clear.
The occupancy factor assumed is an annual 160 hours0.00185 days <br />0.0444 hours <br />2.645503e-4 weeks <br />6.088e-5 months <br /> per year, and specifically assumes a member of the public stands at that TLD location for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per week for four weeks every year. This translates to an occupancy factor of 0.018.
To date, the only activity in that location is delivery personnel who drive by that TLD periodically.
Additionally, and upon review of the Mirion environmental neutron doses reported in the second quarter, it was discovered the neutron doses were excessively high. The most likely cause of the high neutron doses was the application of an operational versus decommissioning dose conversion factor (identified as a source of incorrect doses reported in previous years with quarters of neutron doses 10 times those normally observed).
Mirion was notified, they issued a condition report (CR) (Condition Adverse to Quality, CAQ-226) to confirm the use of an incorrect neutron dose conversion factor and re-issued the corrected neutron environmental dose results. The corrected neutron dose results were used to generate the correct neutron dose ratio.

Executive Summary The license for Zion ISFSI was transferred to Constellation on 11/16/23 with Constellation operations beginning on 11/17/23. This report will cover operations after the transfer and ZionSolutions will provide a separate report for their operations prior to 11/17/23. The 2023 Zion ISFSI Annual Radioactive Effluent Release Report (ARERR) is attached. The ISFSI canisters are the only source of radioactivity on site. No liquid or gaseous effluents were released from the facility in 2023. Those pathways no longer exist with the fuel in stainless steel containers with welded lids. There were no radioactive material or waste shipments from the facility after 11/16/23. There is an overlap in monitoring provided in 2023 by ZionSolutions and Constellation.

Supplemental Information 1.
Abnormal Releases and Abnormal Discharges (e.g. leaks and spills)
There are no effluent pathways.
2.
Non-Routine, Planned Discharges (e.g. pumping of leaks and spills for remediation)
There were no non-routine, planned radioactive discharges for remediation resulting in releases offsite, and therefore, no resulting offsite impact.
3.
Offsite Dose Calculation Manual (ODCM) Changes Revision 12 of the ODCM was issued in Jan 2020 4.
Errata/Corrections to previously issues ARERRs.
Monitoring by Constellation began 11/17/23 with no previous reports.

Appendices In accordance with Regulatory Guide 1.21, Revision 2, tables do not need to be included if all effluent monitoring results were not detectable and met the required lower limit of detection (LLD). As no effluents were released from Zion ISFSI in 2023, effluent data tables are not included in the 2023 ARERR. Additionally, there have been no radioactive waste shipments since Constellation became the licensee on 11/17/23.
Appendix A - Tables There are no effluent pathways. All radioactive material is contained in stainless steel containers with welded lids in concrete over pack structures.
