1. NuScale Generator A Practical Energy Alternative for the Future
By: Dylan Karas & Michael Stephenson

2. Nuclear Energy and its Role in Society
“Energy crisis” due to increasing energy demands
Nuclear energy still does not play a huge role in energy production
Low fuel cost, on-site fuel storage, no greenhouse gas emission

3. Nuclear Fission Enriched uranium-235 is used in most reactors
A coolant is used to transfer heat from the reactor core
1 kg of uranium can produce 3 million times more energy than 1 kg of coal

4. Pressurized Water Reactor
Classification of reactor based on coolant
Safe, proven technology
Pressurized water used within the reactor core
Model for new generation of small modular reactors

5. Small Modular Reactors
Produce less than 300 Mwe
Modular Design
Passive Safety
Still in design stages

6. NuScale Power Module Uranium-235 used in the reactor core
Helical Coil Steam Generator features 2 loops of coolant
Secondary coolant acts as the working fluid in the thermodynamic cycle
Outlet for steam and inlet for feedwater

7. NuScale Power Plant

9. Application of the NuScale Module
Standard thermodynamic cycle
160 thermal megawatt core
45 megawatts of electricity
Plant output based on number of modules
Multi unit plants can still produce electricity during refueling
Desalination
Heat for industrial processes

10. Emphasis on Safety Overall Reactor Safety Improved ECCS (pictured)

16. Viable Energy for the Future
Nuclear energy will play a critical role in the years to come
Small Modular Reactors are emerging as a future source of energy
NuScale’s model is a very realistic and practical model for the future
The applications of SMRs provide versatility
Environmental impact, ethical concerns, and economics will determine the role that SMRs have in the future
