1.0 INTRODUCTION

This Annual Radiological Environmental Monitoring and Radioactive Effluent Release Reports for CY2020 are submitted by the Maritime Administration (MARAD) as licensee for the Nuclear Ship SAVANNAH (NSS) and cover the Calendar Year (CY) 2020 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 February 4, 2021 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, interpretations, 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), and in 10 CFR 50, Appendix I, Section N.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 calendar year pursuant to the ODCM.

In the event that some individual results are not available for inclusion with the report, the report shall be submitted noting and explaining the reasons for the missing results. The missing data shall be submitted in a supplementary report as soon as possible.

Note that TS 3.4.2, Annual Report specifically requires reporting one environmental monitoring item in the Annual Report. In addition to being reported in the Annual Report, the item is also reported here.

Revision 0 4

SAVANNAH Technical Staff STS - 216, Annual Radiological Environmental Monitoring and Radioactive Effluent'Release Reports for CY2020, Revision 0 3.1 TS 3.4.2.1.C. ENVIRONMENTAL SAMPLE ANALYSIS SURVEYS 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 rad10logical conditions in the environment surrounding NSS are insignificant 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 2020.

The results of the CY2020 Radiological Environmental Sampling Results are listed in Appendix

, A, CY2020 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 liquid 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 CPR 50.36a and 10 CFR 50, Appendix I, Section IV.B.1.

4.1

SUMMARY

OF QUANTITIES OF RADIOACTIYE LIQUID EFFLUENTS RELEASED No radioactive liquid effluents were released in 2020.

4.2

SUMMARY

OF QUANTITIES OF RADIOACTIVE GASEOUS EFFLUENTS RELEASED No radioactive gaseous effluents were released in 2020.

4.3 *

SUMMARY

OF THE QUANTITIES OF RADIOACTIVE SOLID WASTE RELEASED There were three shipments of radioactive solid waste in 2020.

Asbestos containing materials (ACM) was generated during ACM abatement of the reactor compartment and containment vessel. ACM abatement was completed in early 2019.

Representative samples of the ACM insulation were collected and sent to GEL Laboratories (GEL) in February of 2019 for radiochemistry analyses of gamma emitting radionuclides (via gamma spectroscopy), Sr-90 and H-3. Bags of ACM insulation materials were consolidated into five (5) twenty-foot shipping (Sealand) containers in preparation for waste disposal transportation. The ACM insulation waste was shipped to EnergySolutions (ES) facility in Kingston, Tennessee by Hittman Transportation on March 30, 2020. The ACM insulation materials were processed for disposal by Bulk Survey For Release (BSFR).

Container Details follow:

• • material for the purpose of transportation. No additional radiation surveys were necessary given this determination. There was sufficient asbestos in the Wll$te that it was transported as hazardous material (Class 9).

The waste was received by ES. There were no issues during loading or transportation of the waste. The material was properly disposed.

5.0 PROCEDURE CHANGES REPORT 5.1 PROCESS CONTROL PROGRAM (PCP) CHANGES Per TS 2.t, The PCP shall describe the administrative and teclinical controls for liquid and solid radioactive waste systems management. Changes to the PCP will be outlined in the Annual Radioactive Effluent Release Report per Section 2.5.2. This submittal shall contain:

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 have been no changes to the PCP since it was reviewed by NRC as part of the approval of License Amendment 17, Reference (a).
