Understanding the Impact of Cl35 on MCFR at Elysium Industries

AI Thread Summary
Cl35's impact on Molten Chloride Fast Reactors, particularly regarding Elysium Industries' approach, is under scrutiny, especially concerning Cl37 enrichment. The discussion indicates that Elysium may opt to forgo Cl37 enrichment due to its unavailability or high costs, instead focusing on developing a larger core to mitigate issues related to sulfur-36 accumulation and corrosion. The motivation for enrichment would primarily be to enhance conversion and breeding efficiency. Participants are encouraged to provide clearer context and sources to better understand the technical implications. Overall, the conversation highlights the challenges and strategic decisions surrounding chlorine isotopes in reactor design.

I was wondering how Cl35 would affect a Molten Chloride Fast Reactor like EI's. Cl37 makes up 24% of the molar mass of chlorine. Is Elysium Industries going to enrich the fraction of Cl37 or is that necessary despite stable sulfur-36 accumulation (Cl35+n=S36)? Is the issue simply corrosion from sulfur?

Their website is a bit vague but a member of their company did go to throcon
 
Well, 90 seconds of Google searching found this.

It sounds like they plan to skip the Cl37 enrichment. It also sounds like their motivation for enrichment would be higher conversion/breeding.

Enriched Cl37 is unavailable or too costly
Develop supply chain, in discussions with Urenco and Centrus Energy, do not enrich chlorine and use larger core, accept lower conversion/breeding
 
That is a great resource, THX.I don't know how I couldn't find that pdf.
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...
