Research Activities in Support of Subsequent License Renewal

Sponsored by the Office of Nuclear Regulatory Research
This poster will provide an overview of Office of Nuclear Regulatory Research (RES) activities in support of subsequent license renewal (the period of extended operation at nuclear power plants from 60 to 80 years). These research activities will improve knowledge on key materials degradation issues during the subsequent license renewal period.  These materials degradation issues are:
  • neutron embrittlement of the reactor pressure vessel
  • stress corrosion cracking and other types of degradation of reactor pressure vessel internals
  • concrete and containment degradation
  • electrical cable qualification and condition monitoring
The NRC addresses subsequent license renewal research activities in collaboration with the Electric Power Research Institute (EPRI), and the U.S. Department of Energy (DOE).
