1.0 INTRODUCTION
This Annual Radiological Environmental Monitoring and Radioactive Effluent Release Reports for CY2022 are submitted by the Maritime Administration (MARAD) as licensee for the Nuclear Ship SAVANNAH (NSS) and cover the Calendar Year (CY) 2022 reporting period.
In accordance with the requirements of TS 2.5 Reporting Requirements,"... the following reports shall be submitted prior to April 1 of each year in accordance with 10 CFR 50.4:
o Annual Radiological Environmental Monitoring Report.
o Annual Radioactive Effluent Release Report.
This report is arranged into four sections following the introduction. Section 2.0 lists items required to be reported by the Technical Specifications (TSs). Sections 3.0 through 5.0 report those items as described in Section 2 below.
2.0 ITEMS REQUIRED BY TECHNICAL SPECIFICATIONS The items specifically required to be included in these written annual reports are as follows:
- a.
TS 2.5.1, Annual Radiological Environmental Monitoring Report (see 3.0).
- b.
TS 2.5.2, Annual_ Radioactive Effluent Release Report (see 4.0).
C.
TS 2.1.1, Changes to the Process Control Program (PCP) (see 5.1).
- d.
TS 2.2.1, Changes to the Offsite Dose Calculation Manual (ODCM) (see 5.2).
This report was reviewed by the Safety Review Committee at the meeting on March 13, 2023. and by the Executive Steering Committee members during its concurrence routing prior to submission of this report totheNRC.
3.0 ANNUAL RADIOLOGICAL ENVIRONMENTAL MONITORING*
REPORT Per TS 2.5.1, The Annual Radiological Environmental Monitoring Report shall include summaries, intei:pretations, and analyses of trends of the results of the radiological environmental monitoring program for the previous calendar year. The material provided shall be consistent with the*
objectives outlined in the Offsite Dose Calculation Manual (ODCM), arid in 10 CFR 50, Appendix I, Section IV.B.2.
The Annual Radiological Environmental Monitoring Report shall include the results of analyses of all radiological environmental samples and of all environmental radiation measurements taken during the previous caiendar year pursuant to the ODCM.
In the event that some individual results are not available for inclusion with the :i;eport, the report shall be sul:>m.itted noting and explaining the reasons for the missing results. The missing data shall be submitted in, 3 supplementary report_ as soori as possible.
. Per the STS~OOS-'020~ Off sit~ Do~~ Calculation Mahual (ODCM);the following two item"s *are specifically*
required to be reported in the Annual Radiological Environmental Monitoring Report.
5.2.1 Direct Radiation Measuring Devices Revision o*
SAVANNAH Te¢1inical Staff
. STS-223~. Ari~tuilltadiofogical Environmental Monitoring and Radioactive Effluent Release Reports for CY2022, Revision O Direct radiation measuring devices, such as thermoluminescent dosimeters (TLDs), optically stimulated luminescent dosimeters (OSL) or equivalent monitoring devices, shall be placed at strategic locations throughout the vessel to monitor the radiation from reactor generated materials. MARAD shall determine these locations on the vessel and shall require dosimeter readings at least semi-annuaily.
5.2.2 Water and Sediment Samples Semi-annually, water samples and bottom sediment shall be taken adjacent to the ship and analyzed for principal gamma emitting radionuclides.
3.1 DIRECT RADIATION MEASURING DEVICES RESULTS Sixty-eight (68) permanently placed thermo-luminescent dosimeter (TLD) monitoring stations are dispersed throughout the non-RCAs of the NSS and in those areas of the NSS that are routinely occupied. Fixed point radiation surveys are performed during TLD change outs. Results from the TLDs from all monitoring stations indicated that readings were insignificant as compared to the background radiation levels. The 2022 Annual report incorrectly stated there were fifty-eight (58) TLD monitoring stations.
3.2 WATER AND SEDIMENT SAMPLES RESULTS Environmental water and sediment samples were taken adjacent to the ship at various times during the calendar year as required by TS. The environmental sample results indicate that any changes in the radiQlogical conditions in the environment surrounding NSS are lllsignificant as compared to the samples taken shortly before the NSS arrived at Pier 13. Therefore, based on the results of the radiological environmental monitoring program, NSS operations at Pier 13 did not have any adverse effects on the health and safety of the public or on the environment in 2022.
- The results of the CY2022 Radiological Environmental Sampling Results are listed in Appendix A, CY2022 Radiological Environmental Sampling Results.
4.0 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT Per TS 2.5.2, The Annual Radioactive Effluent Release Report shall include a summary of the quantities of 1) radioactive ljquid and gaseous effluents and 2) solid waste released from the NSS. The material provided shall be consistent with the objectives outlined in the ODCM and Process Control Program and in conformance with 10 CFR 50.36a and 10 CFR 50, Appendix I, Section IV.B.1.
4.1
SUMMARY
OF QUANTITIES OF RADIOACTIVE LIQUID EFFLUENTS RELEASED No radioactive 1iq1,1id effluents were released in 20.22.

SUMMARY
OF QUANTITIES OF RADIOACTIVE GASEOUS EFFLUENTS RELEASED Np radioacti~re gaseous effluents were released.in 2022. The NSS has two,gaseous contiriµous j:t?lease poin:ts.-:Th~ Deconiinissfoning HVAc:systeins (DRY AC-2) serves ther1tdiologjcal *.

When the AMS-4 alarms, the DHV AC-2 is automatically secured. As documented in the corrective action system, spurious alarms were causing the system to shutdown. Investigation determined that all AMS-4 alarms were below the alarm setpoints and invalid. While the alarm Revision 0

- STS-223, _ ArinU:al Radiological Environmental Monitoring and Radioactive Effluent Release --
Reports for CY2022, Revision O shutdown feature was bypassed to troubleshoot and implement corrective actions to eliminate the conditions causing the spurious alarms, the effluent vent overboard was monitored by a continuous air sampler for both gross alpha and gross beta. No samples indicated activity above background.
In September 2022, an engineering control exhaust trunk was installed on the reactor hatch for localized smoke removal. When it was in use, the effluent was monitored by a continuous air sampler for both gross alpha and gross beta. No samples indicated activity above background.

SUMMARY
OF THE QUANTITIES OF RADIOACTIVE SOLID WASTE RELEASED See Appendix B, Summary of the Quantities of Radioactive Solid Waste Released.
5.0 PROCEDURE CHANGES REPORT 5.1 PROCESS CONTROL PROGRAM (PCP) CHANGES Per TS 2.1, The PCP shall describe the administrative and technical controls for liquid and solid radioactive wasJe systems management. Changes to the PCP will be outlined in the Annual Radioactive Effluent Release Report per Section 2.5.2. This submittal shaltcontain: -
2.1.1.
Information to support the rationale for the change and the changed pages of the PCP or a statement there were no changes; There were no revisions to the PCP in 2022.
5.2 OFFS/TE DOSE CALCULATION MANUAL (ODCM) CHANGES Per TS 2.2,.
The ODCM -shall contain the methodology and parameters used in the calculation of offsite doses resulting from radioactive gaseous and liquid effluents; in the calculation of gaseous and liquid effluent monitoring alarm and trip setpoints; and in the conduct of the radiological environmental monitoring program. Changes to the ODCM will be outlined in the Annual Radioactive Effluent Release Report per Section 2.5.2. This submittal shall contain:
2.2.1 A complete copy of the ODCM with an accompanying criteria and justification for the changes oi; a statement there were no changes; There were no changes to the ODCM in 2022.
