Expertise in all aspects of decommissioning shutdown nuclear reactor sites

Used Nuclear Fuel Management

As the global leader in used fuel management, Orano provides the full range of services to quickly and securely manage and move used fuel to enable accelerated decommissioning.

pool-to-pad transfer of used fuel from the reactor to onsite dry storage
state-of-the-art NUHOMS dry storage systems
inspection of the stored used fuel canisters
storage site aging management technologies and services
reliable and robust transport casks and procedures to move the used fuel offsite

During and after decommissioning, we ensure that the Independent Spent Fuel Storage Installation (ISFSI) operations and security are conducted in accordance with all regulations.

Segmentation & Packaging of Radioactive Components

Orano owns and operates a full suite of advanced segmentation equipment. Segmented components are precisely packaged in shielded containers designed to securely transport this low level radioactive waste.

segmentation tools include large underwater bandsaws, reciprocating saws, and abrasive water jet systems
teams complete hands-on training with actual segmentation tools and procedures at offsite training facility
segmented components packaged according to radioactivity, size and weight to meet all transport requirements
decommissioning experience includes: Yankee Rowe, Connecticut Yankee, Millstone 1 and Rancho Seco, and Maine Yankee

Waste Transport

Since waste transport is a large part of the total cost of decommissioning, our waste management plans incorporate the most cost-effective disposal strategies, consistent with regulatory requirements for each waste type.

manage all phases of large component transportation, including initial planning and studies, licensing, and outreach to public and government stakeholders
determine available methods for processing, packaging, and transporting radioactive waste in conjunction with disposal facility criteria
conduct transport operations with secure, shielded containers, such as Orano's shielded MP197HB transport cask

Stakeholder Engagement

Good stakeholder relations requires investing energy and effort, and proactively developing good relationships and communications. Stakeholders are usually a diverse and site-dependent group, including Federal, State, and Local authorities, regional public and tribal communities, and the associated utility.

start the communication process early to build knowledge and trust with the communities and regulators
provide timely, accurate, complete, and high quality information
strong understanding of EPA and State requirements and other relevant criteria
