OpenMC Tutorial | Simulating the Molten Salt Rreactor Experiment

[@albripi]

Very cool. But still cooler is that they did this thing in the '60s for real without computers.

Yes doing it 'For Realz' back then was The Ultimate Cool. But the joy of this tool, is that we newbie MSR and Thorium Energy Cycle toddlers get to play wannabe nuclear engineers and physicists in a safe sandbox today in the comfort of our homes and computer sim environments. And then OpenMC and DAGMC open up worlds for us to play 'what-if' with new reactor geometries and ideas! 😁

All very clearly explained, an excellent presentation, well done. For anyone keen to analyse or develop fission rectors OpnMC is really going to help but getting the solid model files for a new configuration is the first hurdle. I know how time consuming the solid modelling can be from doing electromagnetic field simulations of devices in radio frequency engineering.

I worked through this example, very nice.

Thanks. Please keep the feedback coming :-)

@@CopenhagenAtomics Hello CA/Eric Knudsen; what sort of compute horsepower is needed to run this uber-cool MSRE SIM? I've got an 'old' but 'max-upgraded' Lenovo T470 laptop with i7-7500U 2-core, hyperthreaded 2.7GHz CPU, up to 20GB RAM available within a Linux Mint VM with 250GB NVME SSD storage available ... will that be suitable to task?

[@erikbergbackknudsen6346]

@@rhonda-my_honda_cb500x3 That would do amply I think - I ran this on an old i7-6600 laptop myself and runtime was something like 20 minutes. Storage tends to only be an issue for the docker containers and cross-section libraries. Same goes for RAM. If you want speed though - these kind of things parallelize really well.

[@KevinMastrovito]

Once defined materials and set the geometry we want to use, how does openmc understands which materials goes where? I'm missing the part in which those materials defined earlier are actually assigned in the geometry we're calling out.

When will you have a power plant ready and running?

[@erikbergbackknudsen6346]

2028 is the plan.

@@erikbergbackknudsen6346 Thats a shame it isnt ready now that gas from Russia is a problem. Could unlimited government backup from the danish government push progress significantly?

[@erikbergbackknudsen6346]

A shame indeed, but I couldn't say how much the process could be sped up. In that I am no expert - I am unfortunately a mere physicist.

China has one running! We can buy a reactor from ThorCon for 1,2 billion. 1 year to build 2 years to handle all legal documents. It can be operational in two years. Why do politicians speak of klimatcrisis, energiecrisis and ignore real solutions. Who needs the crisis...?! Who benefits from crisis...?! Those are the real questions. BE AWARE PEOPLE

[@avinashbaliyan3044]

Approach of CA ( Copenhagen atomics ) to build non nuclear lab models of molten salt apparatus is very agile and is a marvelous idea . @erik what are your thoughts about the Sealer reactor the Swedes are developing , instead of salt they are using Lead as it has high melting point and other beneficial properties ?. Good luck to CA for their project.!!
