RSCS and EnergySolutions form Joint Venture to Decommission the N.S. Savannah


Salt Lake City, Utah – March 29, 2022 – Radiation Safety and Control Services Inc. (RSCS) and EnergySolutions, today announced a partnership to decommission the world’s first nuclear-powered merchant ship, the N.S. Savannah.


RSCS started working with the U.S. Department of Transportation’s Maritime Administration in 2007 on Phase 1 decommissioning preparations and completed this phase in early 2021.  The RSCS-EnergySolutions Joint Venture (Nuclear Ship Support Services, LLC) is now conducting Phase II and Phase III decommissioning where remediation is expected to be complete mid-2023 and License termination expected to be completed by 2025.


“This ship is designed with a one-of-a-kind reactor and associated support systems,” stated Jay Tarzia, Executive Director, RSCS.  “The goal of the project is to safely and surgically decommission the ship, maintaining maximum ship integrity to preserve this national historic landmark.  To complete this job we have assembled a world-class team with our partners EnergySolutions to achieve this goal.


“This is a unique opportunity for EnergySolutions to apply our decommissioning experience to the decommissioning efforts of the N.S. Savannah and we value our partnership with RSCS on this important project,” said Ken Robuck, President and CEO of EnergySolutions.  “We are confident as a team we will safely decommission the Savannah applying lessons learned from our experience at commercial reactor decommissioning projects while at the same time preserving this national treasure.”


A National Historic, Nuclear Engineering and Mechanical Engineering Landmark, the N.S. Savannah was commissioned July 20, 1956 under President Eisenhower’s “Atoms for Peach Program.”  The ship, originally constructed under a joint agreement between the U.S. DOT Maritime Division and the Atomic Energy Agency, is currently licensed with the NRC.  An 80 Mw reactor powered the ship, which weighs 9,570 tons with an overall length of 595 feet and was operated by a sixty-person crew.


Decommissioning activities include safely removing the control rod drive system, pressurizer, reactor pressure vessel, neutron shield tank, steam generators, primary system piping, reactor vessel and all primary system components.  All of this material is considered low-level waste and will be safely transported and disposed of at the EnergySolutions “Clive” disposal facility located in Utah’s West Desert.


Our joint team will carefully perform the decommissioning to preserve the ship for future use as a museum.

RSCS Regulatory and Technical Expertise Helps Nuclear Utility Avoid a NRC White Finding

In late 2020, RSCS was requested to assist the management of a Midwestern nuclear power plant in responding to a potential NRC inspection finding that was initially screened as White. NRC inspectors believed that during preparation of a radioactive resin shipment, plant personnel failed to meet regulatory requirements, resulting in a performance deficiency of low to moderate safety significance or White. The Nuclear Energy Institute (NEI) estimates the cost to a plant in response to a White finding is about $1 M due to necessary corrective actions and supplemental NRC inspection activities. The RSCS Team coordinated a two-prong attack on this situation.

Ellen Anderson teamed with the regulatory staff and Radiation Protection Manager (RPM) to assist in their response to NRC. She provided regulatory guidance and recommendations to plant staff based on her many years of experience in this area. She addressed the regulatory aspect by researching past NRC precedence on similar industry performance deficiencies that NRC had previously screened as Green, or low safety significance.

In addition, Nasser Rashidifard demonstrated his technical expertise by performing independent Microshield dose calculations on the resin liner in parallel with plant staff. His calculations were 100% aligned with that of the client, concluding that dose rates on the resin liner did not meet the criteria for a White finding.

Based on their independent reviews on the two perspectives, both Ellen and Nasser concluded that this performance deficiency constituted a Green finding, not a White one.  They were able to provide additional information to the client which allowed a more complete assessment of the regulatory significance.

In late January, RSCS was notified by a very pleased plant management that the final NRC screening of this finding was determined to be Green rather than White.  The RPM noted that their success in overturning the White finding was due to the of the RSCS team. Not only did this maintain the client’s regulatory margin with the NRC but also saved them a considerable expense.


Advanced Radiological Assessment Technology Demonstrated at RSCS Technology Expo for Nuclear Decommissioning Decision Makers

RSCS sponsored a Technology Expo at our Seabrook NH facility to demonstrate several high technology solutions to nuclear decommissioning decision makers who are planning for the D&D of complex non-routine nuclear sites. We have been working with several vendors of cutting-edge robotics, imaging and in-situ sampling technologies to provide a comprehensive solution for assessing high radiologically impacted areas. Our integrated technology solution combined with our years of experience in decommissioning drove impactful discussions on how to best approach some of the most difficult decommissioning projects in the USA. 

RSCS 3DCDE model of high radiation area

Our Technology Expo provided a detailed overview and full demonstration of how new technology can provide data that enhances our advanced modeling capabilities. RSCS has built powerful 3D Building Information Models (BIM) from nuclear facility designs and standard operational survey data sets and have developed dynamic and interactive asset inventories for several nuclear sites. Imaging and data collected from advanced technologies augment these complex models which are coupled to site and regional Geographic Information Systems (GIS) in one Common Data Environment (CDE), resulting in highly detailed 3D maps of radiological conditions within nuclear plants, their subsurfaces, and surrounding regions. We have harnessed the power of robotics and remote detection and sampling technologies to provide this data through radiological assessments that are ALARA and low risk. Once a remote survey is completed and data is integrated into 3DCDE models, plant management has the information they need to determine areas that are safe to perform more comprehensive manned surveys to further enhance the data set. Final models can then be used for decision making on workflow and execution. As D&D efforts proceed, the dynamic models can be routinely updated to track the removal of assets and source term and make determinations on the appropriate waste classifications and demolition sequences and strategies. RSCS experience has confirmed that detailed front-end and in-process characterizations provide the most efficient means for effective work planning, which positively impacts cost, schedule adherence, regulatory compliance and worksite safety.

FARO Trek robot with 3D mobile scanning for remote and autonomous data capture in challenging environments

Following a series of presentations, decision makers where provided with hands-on live demonstrations of the technologies discussed, which included the Trek robot that integrates LIDAR-scanning to provide comprehensive 3D models of an area, and the WARP robot that provides radiological dose rates, air sampling, smear data and gamma distribution and isotopic identification, imaging and mapping using H3D’s CZT detectors. Finally, our WARP was equipped with a Viridian Scope laser extraction system that sampled the surface layer of concrete for radioactive contamination. These remotely operated robots and assessment technologies can safely enter high radiation areas to provide data on the current conditions inside the impacted areas. This assessment solution provides our clients with the ability to investigate areas with ambient dose rates up to 100 R/h that are impractical to characterize using traditional techniques.

WARP robot with Viridian Scope laser extraction sampling for in-situ analysis of surface contamination

The robotic platforms demonstrated are industrial strength, can withstand harsh environments, fit into confined and constrained spaces, and navigate successfully around obstacles. The Trek robot was designed and built to perform complex navigational operations such as walking up stairs. WARP performs diverse analytical operations using a custom designed and built payload management system that allows for efficient room or cubicle entries. To test and demonstrate the capabilities of these robotic platforms and technologies, a full scale realistic shielded equipment room was built including components, radiological conditions and entry challenges. The mock-up environment provided an ideal backdrop for demonstrating the power and capacity of this next generation integrated technology solution.

RSCS is proud to offer this state-of-the-art technology to the nuclear decommissioning industry.  After our participants observed several full-scale live demonstrations, they were convinced of the readiness and utility of this technology for their sites and are already envisioning new ways to use this assessment technology to benefit their decommissioning efforts. RSCS looks forward to deploying this fully integrated and functioning capability and incorporating future technologies to our platforms to adapt to the needs of our clients across our industries.
