Reactor Prestressed Concrete Vessel Tendon De-Tensioning Demonstration

Nuclear Restoration Services Limited seeks qualified suppliers to demonstrate the safety and technical viability of two cutting techniques for de-tensioning reactor Prestressed Concrete Vessel (PCV) tendons. This project addresses a critical challenge where anchorage corrosion has prevented the use of conventional stressing jacks in most operational areas. Suppliers should be prepared to: (1) develop and validate two distinct cutting methodologies, (2) ensure safety compliance throughout de-tensioning operations, (3) provide detailed feasibility assessments, and (4) document findings to support future decommissioning activities. Experience with nuclear facility operations, materials science, and specialized cutting equipment is essential.
