In summary, researchers at Sandia have discovered that using the Brayton cycle with supercritical CO2 can increase efficiency by 50% compared to traditional steam turbine technology used in nuclear reactors. This also has potential safety benefits due to the fire-suppressing properties of CO2. However, there are still some issues to be addressed, particularly with the core temperature. It is unclear if this technology will be implemented in existing reactors or used in future designs, but it shows promise for improved energy production. Further study and development may be needed before widespread use.

I suppose it's safer too, since the CO2 would help to suppress fire hazards.

There are issues with the core based on the temperature cited. It's not so cut and dry.

I know the PI.

Wow, that's really impressive! It's great to see advancements in technology that not only increase efficiency, but also have safety benefits. I wonder if this new technology will be implemented in existing nuclear reactors or if it will be used in future designs. Either way, it's exciting to see the potential for improved energy production. Do you know if there are any plans to further study and develop this technology?
