Mech engineering work in nuclear reactors

Click For Summary

Discussion Overview

The discussion centers on the roles and responsibilities of mechanical engineers in the context of nuclear reactors, specifically fusion and fission reactors, as well as the potential overlap with particle accelerators. Participants explore various aspects of mechanical engineering relevant to these fields.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about the specific work mechanical engineers perform in building fusion and nuclear reactors, expressing interest in the potential of fusion energy.
  • Another participant outlines various mechanical engineering tasks in fission power plants, including stress analysis, heat transfer, fluid flow, material corrosion, and the design of pumps and valves.
  • A participant suggests that mechanical engineers can also work in control systems, indicating a potential for interdisciplinary skills development.
  • There is mention of the predominance of mechanical engineering tasks compared to nuclear engineering roles on-site in fission plants.
  • One participant seeks clarification on whether the principles of mechanical engineering in nuclear reactors can be applied to particle accelerators.

Areas of Agreement / Disagreement

Participants generally agree on the significant role of mechanical engineering in nuclear reactors, but there is no consensus on the specifics of mechanical engineers' contributions to fusion reactors or the applicability of these principles to particle accelerators.

Contextual Notes

The discussion does not resolve the differences in understanding the roles of mechanical engineers in fusion versus fission reactors, nor does it clarify the extent to which principles apply to particle accelerators.

Who May Find This Useful

Individuals interested in mechanical engineering applications in nuclear energy, students considering careers in engineering, and professionals exploring interdisciplinary roles in energy sectors.

Hi all,

I would like to know what's the kind of work a mechanical engineer has to perform when being part of the team encharged of building a fusion or a generic nuclear reactor. I find many areas in mechanical engineering attractive, but I believe that fusion reactors have great potential in delivering sustainable and efficient energy, so I wonder what a mechanical engineer has to offer when it comes to that.

Also, could I extrapolate the question and include particle accelerators as well? (I suppose they all have the same basic principle. Correct me otherwise.)

I don't really know about fusion machines but in a fission power plant there is a huge amount of mechanical engineering. Stresses and strains during normal and upset conditions, heat transfer & fluid flow to get the energy from the core into turning the turbine, corrosion of the materials, changes in physical properties as the materials age, welding and bolted connections, pumps, valves, heat exchangers, piping design... and on and on. Most of the work is mechanical engineering, closely followed by instrumentation & control / electrical engineering. There are actually very few nuclear engineers working onsite.

@gmax137 Nice, thanks for your answer, mate. For what I've read, mechanical engineers can work in control systems as well, right?
 
Yes, Mech engineers can and do work in controls. You will find that engineers develop hybrid skills over time, sort of on the job training. The discipline or area (mech, elec, etc.) you pursue in school is just the beginning.
 
Cool. Are you an engineer yourself?
