Reactor Vessel Internals Segmentation
Segmentation Plan
Stellar Nuclear Services, LLC can provide a unique service to clients entering this phase of their Decommissioning. Our personnel have experience relating the plan for a Reactor Segmentation to the eventual actual segmentation, through day-to-day participation with the segmenting contractor. A thorough review and schedule can be developed to accurately and precisely track the project so as to follow the segmentation plan and meet the client’s goals. This summary document would seek to plan for (down to the component) a loading plan that can act to serve as a check for the eventual disposal path determination, as well as determining the packaging and transportation cask needs.

Working in concert with the client or segmentation contractor, Stellar Nuclear Services, LLC personnel can track the loading of segmented components into liners, ensuring that the planned package is compliant with prior characterizations. Stellar Nuclear Services, LLC personnel can review of items such as container selection, ensuring that the client obtains any necessary cask use certifications, auditing of the container’s Certificates of Conformance (C of Cs), and pre-use inspections.
