Exploratory Workshop for Developing an Advanced Reactor Generic Environmental Impact Statement (GEIS)
Jack Cushing Mallecia Sutton NRC January 8, 2020
2 Objectives of the Workshop
- Understand types and sizes of advance reactors under development
- Determine the viability of developing a GEIS for advanced nuclear reactors
- Discuss possible strategy for a GEIS
3 What would an Advanced Reactor GEIS address?
- Define the scope of the environmental effects of construction and operation of advanced reactors
- Identify and determine generic and site-specific environmental impacts
4 NRC Needs to Know
- Footprint and power output level of the advanced reactor
- Construction considerations Constructed/assembled onsite or manufactured elsewhere for delivery and installation Amount of land required to construct the reactor Duration of construction Number of construction workers Infrastructure needed (T-lines, roads, etc.)
5 NRC Needs to Know Operation Considerations Length of operation Core lifetime and nuclear fuel management Number of operation workers Radiological and non-radiological effluents released during reactor operations (gaseous, liquid) and solid wastes Cooling system designs

9 Reactor Utilization
- Demonstration
- Electric production
- Desalination
- Process heat
- Others?
10 Possible Paths Forward
- No GEIS
- All technologies
- Micro-reactor only
- Intermediate-sized reactor
- Large reactor
- Combinations of the above
- Other considerations
11 Power level Review Example
- Less than 40 MWth
- 40 MWth to 300 MWth
- 300 MWth and greater
12 Review Example (cont.)
Example Resource Less than 40 MWth 40 MWth to 300 MWth Greater than 300 MWth Land use 10 acres or less Very small footprint 10 acres to 199 acres Small footprint 200 acres or more Water Resources (Heat-Dissipation Systems)
Not likely to require cooling water Potential for cooling water Likely will need cooling water Work Force (Construction &
Ops)
Very small number Small number Larger number Ecology, Cultural, Environmental Justice Site specific Site specific Site specific
13 Important Dates
- Input to NRC by January 24, 2020
- NRC staff will assess and consider input to prepare a summary report by February 15, 2020
14 Conclusion
- Possible structures for a GEIS
- Types and sizes of advanced reactors to be addressed in the GEIS
- Example of how the advanced reactor design impacts the environment
- Other ideas
