Letter from Tanya E. Hood (NRC) to Erhard W. Koehler (MARAD), dated December 16, 2024, Nuclear Ship Savannah - Request for Confirmatory Information Related to Requested Licensing Action Re: Submittal and Request for Approval of the License Termination Plan (ML24352A199)
In response to Reference (a), the United States Maritime Administration (MARAD) confirms the following information:
The radiation safety officer position has been and will be maintained until License Termination.
Throughout the remediation process, the RSO routinely evaluated work activities, contamination levels, and worker exposures to ensure ALARA was maintained. The RSO will continue to perform such activities as required until the license is terminated.
An administrative limit of 15 mrem/y was established to ensure the actual residual radioactivity will be significantly less than 25 millirem per year (mrem/y).
No elevations ofresidual radioactivity will exceed the 15 mrem/y derived concentration guideline limit (DCGLw) concentrations.
All sediment (sludge) and water containing residual radioactivity has been removed.
Processes are in place that are more restrictive than in the License Termination Plan ( e.g., processes or procedures are established for decontamination personnel to attempt to remediate any area causing instruments to have readings in excess of 1,000 cpm).
Removable activity will be reduced to less than 10 percent of the total activity present consistent with assumptions associated with developing the DCGLs.
MARAD confirms the accuracy of the information above and that these actions will ensure that actual residual radioactivity remaining at license termination will coincide with a much lower hypothetical dose to an average member of the critical group than 25 mrem/y and will demonstrate the residual radioactivity in the N.S. SAVANNAH at license termination is ALARA.
