UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 March 18, 2021 Mr. Erhard W. Koehler Senior Technical Advisor, N.S. Savannah U.S. Department of Transportation Maritime Administration (MAR-640.2) 1200 New Jersey Avenue, SE W25-209/212 Washington, DC 20590-0001

SUBJECT:

NUCLEAR SHIP SAVANNAH - ISSUANCE OF AMENDMENT 18 TO REVISE THE TECHNICAL SPECIFICATIONS TO REMOVE REDUNDANT REPORTING AND CONTROL REQUIREMENTS AND ELIMINATE THE REQUIREMENT FOR A DRAFT HULL STRIPE

Dear Mr. Koehler:

By application dated September 4, 2020 (Agencywide Documents Access and Management System [ADAMS] Accession No. ML20255A084), the United States Maritime Administration (MARAD), requested U.S. Nuclear Regulatory Commission (NRC) approval of an Amendment revising the Nuclear Ship SAVANNAH (NSS) Technical Specifications.

The proposed amendment would revise the Technical Specifications to (1) remove a redundant environmental sampling reporting requirement, (2) remove a redundant access control requirement, and (3) remove a hull striping requirement that is not required and is inconsistent with active decommissioning ship conditions.

The NRC staff has completed its review of the proposed amendment to your license. The amendment approving the proposed changes is provided in Enclosure 1. Enclosure 2 contains the NRC staffs associated safety evaluation. The NRC staff has determined that this action is subject to a categorical exclusion pursuant to 10 CFR 51.22, and therefore did not further evaluate environmental impacts.

A notice of issuance of amendment has been forwarded to the Office of Federal Register for publication.

In accordance with 10 CFR 2.390 of the NRCs Agency Rules of Practice and Procedure, a copy of this letter will be available electronically for inspection in the Publicly Available Records component of NRCs ADAMS. ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.

E. Koehler If you have any questions, please contact me at 301-415-3017, or via e-mail at theodore.smith@nrc.gov.

Sincerely, Theodore B. Smith, Project Manager Reactor Decommissioning Branch Division of Decommissioning, Uranium Recovery and Waste Programs Office of Nuclear Material Safety and Safeguards Docket Nos. 50-238

ENCLOSURE 2 SAFETY EVALUATION UNITED STATES MARITIME ADMINISTRATION NUCLEAR SHIP SAVANNAH DOCKET NO. 50-238

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDS RELATED TO THE N.S. SAVANNAH AMENDMENT NO. 18 TO FACILTY LICENSE NO. NS-1 DOCKET NO. 50-238

1.0 INTRODUCTION

By application dated September 4, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20255A084), the United States Maritime Administration (MARAD), requested approval of a proposed license amendment revising the Nuclear Ship SAVANNAH (NSS) Facility Operating License NS-1 Technical Specifications (TS). MARAD is requesting a revision to the TS to (1) remove a redundant environmental sampling reporting requirement, (2) remove a redundant access control requirement, and (3) remove a hull striping requirement that is no longer required and inconsistent with active decommissioning ship conditions.

2.0 BACKGROUND

The NSS has been shut down since 1970 and was defueled in 1971. In 1976, the license was changed to a possession-only license (41 FR 21706), and on April 23, 2018, Amendment Number 15 was issued to allow dismantlement and disposal (i.e., active decommissioning)

(ADAMS Accession No. ML18081A134). Presently, the ship is scheduled to remain at the Canton Marine Terminals in Baltimore under a long-term lay berth contract.

3.0 REGULATORY EVALUATION

3.1 Proposed Deletion of TS 3.4.2.1 c:

TS 3.4.2.1 requires submission of annual report which shall include site status, a summary of radiological survey results and monitoring station readings, a description of the principal maintenance performed, any unauthorized entries into radiologically controlled areas (RCAs),

any degradation of radioactive material control boundaries, and occupational exposures, and a summary of environmental sample analysis survey results. The summary of environmental survey results is nearly identical to the requirement of TS 2.5.1, which requires annual reporting of the results analyses of all radiological environmental samples and all environmental radiation results taken during the previous calendar year pursuant to the Offsite Dose Calculation Manual (ODCM).

The effective duplication of requirements inadvertently resulted from license amendment 17, which revised and consolidated the existing custom-formatted TS into a format consistent with the Standard TS for nuclear power plants, as provided in the NUREG series 1430 - 1434,

Standard Technical Specifications. The TS changes retained 1 programmatic control for radioactive effluents and radiological environmental monitoring in the TS, but moved procedural details from the TS into the ODCM or the licensees Process Control Program. Since the scope of TS 3.4.1.2 c is the same as TS 2.5.1, it is redundant and can be deleted with no impact to the TS effectiveness.

NRC staff review has determined that the proposed change is administrative and does not alter compliance with NRC regulatory requirements.

3.2 Proposed Deletion of TS 3.7.1.1 Currently, this TS requires all containment vessel (CV) entrances to be either manned or secured, in or to control access to the CV. This TS originates from 1976, in license amendment 16, when the NSS was first placed into mothball status. The CV is currently an RCA and requires access controls only while it is an RCA. TS 3.7.1.2 requires controlling access to all RCAs. Since the scope of TS 3.7.1.1 is effectively a subset of the scope of TS 3.7.1.2, and the requirements are identical (i.e. control access), TS 3.7.1.1 is redundant to TS 3.7.1.2 and can be deleted with no impact to the TS effectiveness.

NRC staff review has determined that the proposed change is administrative and does not alter compliance with NRC regulatory requirements.

3.3 Proposed Revision to TS 3.7.3.1 Currently, TS 2.7.3.1 requires painting yellow draft stripes that allow distant observers, such as roving patrols monitoring vessels anchored offshore, to monitor the ships draft. The requirement is appropriate for a ship that is in protective storage and whose draft and trim are not expected to change. For example, when the NSS was located at the James River Reserve Fleet at Fort Eustis, VA, the ship was in the middle of an approximately two-mile-wide section of the James River. In this situation, on shore personnel observed the draft level stripes by video camera and a roving river patrol.

During active decommissioning significant changes in the ships draft and trim will occur as large reactor and auxiliary system components are dismantled and removed from the ship.

Dismantling equipment brought on and off the ship may also result in a change to the ships draft. The resulting significant changes in draft and trim would require routinely repainting draft level stripes, which are not needed during active manning and decommissioning.

The ship's draft will be monitored daily as an indication of hull integrity. Unexpected changes in ships draft indicate possible compromised integrity, such as water in-leakage or flooding. If there is an unexpected change in the ships draft, the ship shall be surveyed to determine the cause of the draft change. If leakage or flooding is the cause, the ship will be pumped out, and repairs made as may be required, including dry-docking if determined necessary, in order to assure that the integrity of the hull is maintained.

NRC staff review has determined that the proposed change is administrative and as does not alter compliance with NRC regulatory requirements. However, NRC staff determined that the addition of a requirement to record daily draft observations would be appropriate to provide a

means to compare changes in ships draft to work logs to identify any potential unexpected deviations. Therefore, NRC staff has added language to require recordation of daily draft observations as described in the next section.

4.0 TECHNICAL EVALUATION

In the license amendment request, MARAD indicated that all three proposed changes to the NSS TS are administrative and involve no technical issues, and do not alter compliance with any applicable regulatory requirements or other criteria.

MARAD has proposed changes for the NSS TS, as follows:

  • TS 3.7.3.1 will be revised to state The ship's draft will be monitored daily as an indication of hull integrity. Unexpected changes in draft are indications of compromised integrity, such as water in- leakage or flooding. If there is an unexpected change in draft, the ship shall be surveyed to determine the cause of the draft change. If leakage or flooding is the cause, the ship will be pumped out, and repairs made as may be required, including dry-docking if determined necessary, in order to assure that the integrity of the hull is maintained.

NRC staff have determined that observations of the ships draft should be recorded so that changes could be compared with work activities at a later date to confirm there were no unexpected changes. Accordingly, TS 3.7.3.1 will be revised to The ship's draft will be monitored and recorded daily as an indication of hull integrity. Unexpected changes in draft are indications of compromised integrity, such as water in- leakage or flooding. If there is an unexpected change in draft, the ship shall be surveyed to determine the cause of the draft change. If leakage or flooding is the cause, the ship will be pumped out, and repairs made as may be required, including dry-docking if determined necessary, in order to assure that the integrity of the hull is maintained.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment includes changes to the license that eliminate redundant requirements and is therefore administrative. NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration (85 FR 194; October 6, 2020), and there has been no public comment on such finding. Accordingly, the amendment meets the eligibility criteria for categorical exclusions set forth in 10 CFR 51.22(c)(9) and 10 CFR 51.22(c)(10)(ii). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.

6.0 STATE CONSULTATION

On March 4, 2021, the State of Maryland was notified of the proposed changes to the N.S.

SAVANNAH license to revise the Technical Specifications associated with effluent and environmental monitoring and reporting requirements. Eva S. Nair, Program Manager, Radiological Health Program, Maryland Department of the Environment, responded on March 5, 2021, with no comments or questions.

7.0 CONCLUSION

The changes proposed by this license amendment would revise the TS to delete TS 3.4.2.1 c.

and 3.7.1.1 as they are redundant, and also revise TS 3.7.3.1 to modify the method employed for monitoring the ships draft in a manner consistent with planned ship decommissioning.

Therefore, the staff concludes, based on the considerations discussed above, that: 1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; and 2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendment will not be inimical to the common defense and security nor to the health and safety of the public.
