The link leads to a Thorcon Executive Summery, an initial and evolving document, that suggests that Thorcon is moving toward a preconceptual phase of its power producing MSR development. Thorcon is very ambitious, and its plans would seemingly bypass the United States Nuclear Regulatory Comission. This is possible if Thorcon intends to build its MSRs outside the United States. There are hints that the manufacturing facility might be located in a South Korean, Ship Yard. My vision prevents me from reading this document, and unfortunately Chrom's speech feacher does not work with pdf documents. My comments are gleaned from what my poor vision can make out about the text.
I have spotted a few things about this text. First the 4 module design appears to draw on ideas developed by Ed Bettis during the 1960's. Secondly, the plan takes into account the graphite problem which concerned the ORNL design team during the 1960's. This also appeaqrs to be the case in David LeBlanc's design for theIMSR, which forsees a core life of only 7 years. I believe that the solution to the graphite problem is the introduction of graphite pebbles into the core fluid. The pebbles can serve as the core moderat, and then floated out of the core when exposure to neutron bombardement ends theit useful life.
