Discussion Overview

The discussion revolves around the impact of Cl35 on Molten Chloride Fast Reactors (MCFR) at Elysium Industries, focusing on the potential need for Cl37 enrichment and its implications for reactor performance and corrosion issues related to sulfur-36 accumulation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions how Cl35 affects MCFRs, specifically regarding the necessity of enriching Cl37 in light of stable sulfur-36 accumulation.
  • Another participant requests clarification and context for the initial question, indicating a lack of understanding.
  • A participant mentions that a company member attended a relevant conference, suggesting a connection to the topic.
  • Research indicates that Elysium Industries may not pursue Cl37 enrichment due to availability and cost issues, opting instead for a larger core design that accepts lower conversion and breeding rates.
  • A participant expresses gratitude for a resource that clarifies the situation regarding Cl37 enrichment.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessity of Cl37 enrichment, with multiple views presented regarding the implications of using Cl35 and the company's strategy.

Contextual Notes

There are limitations in the discussion regarding the clarity of the initial question and the specific technical details about the reactor's design and operational strategies.

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.
