Looking for research which encompasses both plasmas and fission.

In summary, the conversation discusses several topics related to the use of magnetohydrodynamics theory in designing liquid metal cooled reactors. This includes the possibility of fusion-fission hybrid systems and the use of metal fuels, which have lower operating temperatures but also present challenges in terms of fuel reliability and retention of fission products. There is also mention of a concept involving UF6 cores with highly enriched uranium, but it is unlikely to be adopted for commercial use.

So far I've only found some leads into the use of magnetohydrodynamics theory in designing liquid metal cooled reactors. Anyone know of any other topics?

There has been thought about fusion-fission hybrid in which the 14 MeV neutrons from (d,t) fusion would be used to cause fast fissions in a uranium blanket. Fission systems normally use solid fuel, with the exception of the molten salt reactor (MSR). Solid fuel form trap the solid fission product and most of the volatiles and gases, except for fast and high temperature reactors which experience columnar grain growth and often develop a central void as gases migrate up the thermal gradient.

Metal fuels operate at lower temperature than ceramic fuel, although thermal conductivity can decrease with increasing fissions as fission products accumulate in the metal matrix. Metal fuel can be annular to allow fission gases and volatiles to migrate into the central void, but then one needs a sufficient plenum.

Metal fuels are not approved for commercial LWR operation, and are not likely to be any time soon. A critical issue for commercial plants is fuel reliability, i.e., ideally no failures, and retention of fission products under normal and anomalous operating conditions. Ideally, one avoids postulated accidents.

There have been concepts involving UF6 cores with highly enriched uranium, but such a concept would not be adopted for a commercial power reactor. The core would conceivably be a plasma, but it would probably have to be a coupled core with a solid (dense) component.

Some good ideas here man. You always come through with the goods!
 

1. What is the current state of research on plasmas and fission?

Currently, there is ongoing research on the use of plasmas in nuclear fusion as a potential source of clean energy. Additionally, there is research on how plasmas can be used to enhance nuclear fission reactions for more efficient energy production.

2. How do plasmas and fission relate to each other?

Plasmas and fission are both important areas of study in nuclear physics and energy production. Plasmas are ionized gases that are used in nuclear fusion research, while fission is the splitting of atomic nuclei to release energy. Both have the potential to provide sustainable and clean sources of energy.

3. What are some recent advancements in research on plasmas and fission?

Recent advancements include the development of new plasma confinement techniques for fusion reactions, such as the use of magnetic fields. There have also been advancements in understanding the behavior of plasmas at high temperatures and densities, which is crucial for efficient fission reactions.

4. What are some challenges in studying plasmas and fission?

One of the main challenges is creating and maintaining stable and controllable plasmas for fusion reactions. Another challenge is developing materials that can withstand the extreme conditions of plasmas and fission reactions. Additionally, there are safety concerns and ethical considerations surrounding the use of nuclear energy.

5. How can research on plasmas and fission impact our future?

Research on plasmas and fission has the potential to greatly impact our future by providing a sustainable and clean source of energy. Fusion reactions, if successfully harnessed, could potentially produce unlimited amounts of energy without producing greenhouse gases or nuclear waste. Fission reactions can also provide a significant amount of energy, but there are concerns about the safety and management of nuclear waste. Continued research in these areas could lead to advancements in energy production and a more sustainable future.
