NRC Long Term Research Plan
- Long-term regulatory research is forward-looking regulatory research performed to provide fundamental insights and technical information, or address potential technical issues or identified gaps in support of issues or identified gaps in support of anticipated future (greater than 5 years)
NRC needs.
Long-term Research Process Developed through a variety of means:
- solicitation of research ideas from staff and solicitation of research ideas from staff and management from each of the program offices and RES
- review of existing topic-specific and program-specific research plans from both NRC and external organizations
- review of selected reports on NRC research activities
- inputs from external stakeholders including other government organizations, industry groups, and several of the national laboratories

Extended Dry Storage In February, 2010, the Commission directed the staff to review the regulatory programs for spent fuel storage and transportation to evaluate their adequacy for ensuring safe and secure storage and transportation beyond 120 years.
The staffs review should identify risk-informed, performance-based enhancements that will bring increased predictability and efficiency to the regulatory processes.
The staff should develop a project plan for Commission approval.
The staff is currently working on the project plan.
The staff is participating on the EPRI/DOE dry storage working The staff is participating on the EPRI/DOE dry storage working group Present research includes casks in a marine environment; modeling of cask drop tests; testing of high burnup fuel for material properties; and fuel burnup credit for storage.
