Concrete Aging and Degradation in NPPs: LWRS Program R&D Progress Report

摘要

Since 2000, numerous nuclear power plants (NPPs), which were originally licensed and designed to operate up to 40 years, have undergone a license renewal process to extend their lifetime up to 60 years. However, extensions to 80 years and beyond are being considered to meet the future national energy demands. The license extension process has established a renewed focus on the long-term degradation processes in NPP materials.
