During the week of March 22, 2021, USA Nuclear performed an on-site assessment of Palisades Nuclear Power Plant to determine the process and tasks to be performed in security to decommission the site safely and successfully within a pre-defined plant shutdown schedule. A separate report was developed and provided to site leadership identifying USA Nuclear’s observations and recommendations. Steven D. Root, P.E. and Senior Nuclear Engineer Consultant at USA Nuclear, conducted the subject onsite security assessment.

USA Nuclear will provide technical support to Entergy Services in completing the Wet and Dry Storage Phases of the Palisades NPP Decommissioning Project. The scope of work as defined includes Nuclear Security Engineering and Civil/Structural Engineering subject matter expertise.
USA Nuclear will operate as Prime Contractor to Entergy Services in delivering the required technical and regulatory expertise, engineering calculations, construction, as well as other modification activities and support needed to complete the Palisades NPP Decommissioning Project. USA Nuclear will assist Entergy Services with planning modifications and security changes to reduce security costs for the wet and dry storage phases for decommissioning of Palisades to reduce long-term security costs.

Phases of Decommissioning
During the wet storage phase of decommissioning, four types of potential changes can reduce long term security costs:
- De-activation of vital areas and installation of barriers
- Discontinuation of compensatory measures to include surveillance
- External strategy – removal of buildings and installation of delay barriers
- Internal strategy – block or add delay barriers to pathways to the spent fuel pool
During the dry storage phase of decommissioning, modifications are needed to convert the Independent Spent Fuel Storage Installation (ISFSI) from a plant-support facility to a stand-alone ISFSI. There are four general areas of work required:
- Expand the ISFSI to accommodate complete offload of the Spent Fuel Pool
- Provide an ISFSI-only Central Alarm Station (CAS) inside the ISFSI Protected Area
- Provide secure storage for the spent fuel transfer machinery when stored at the ISFSI
- Prepare new security plans for the stand-alone ISFSI in accordance with current NRC staff guidance
USA Nuclear provides full-suite service that includes: performing reviews of policies and regulations impacting client industry; conducting onsite walkdowns to perform facility vulnerability assessments and analysis; and providing recommendations that consider use of modern security technologies, manpower enhancements, and defensive strategy modifications to optimize security and defense. Upon review of recommendations, USA Nuclear supports clients in implementation and security force deployment.
