Conceptually if the core is 100% factory built and shipped in a single module and is substantially simpler than water cooled reactors, combined with thermodynamic efficiency around 50% (less thermal power produces same electricity), the concept does have a lot of potential.Amur_Tiger wrote:My understanding is that fuel makes up a relatively small amount of even operational costs, nevermind the cost of initial investment ( and insurance based on long build times ).
From what I've heard and read about IMSR it should have a fairly easy time getting less cost per MWe in generation, especially if we're limiting scope to Western designs. It would actually be interesting to know just how much money would have to be spent on fuel and waste management to neutralize the advantage of halving the capital costs and workforce ( simpler passive safety suggests that staff on site should go down as well after all).
Just to quantify this a bit more the AP-1000s in the US seem to be coming in at around 7 billion each. You'd need the largest IMSR to come in at less then 1.75 billion to beat capital costs at which point it starts to become economically attractive. How realisitc or not is that?
The basic advantages of an MSR, combined with Dr LeBlanc extreme KISS design approach should succeed.
Unfortunately Terrestrial has been quite silent about the details for a design that could be submitted to the CNSC for approval in a year or two. They have little to gain by divulging their latest design choices and a lot to loose as competitors pick apart their design, trying to find problems everywhere (real or not).
I can only hope that CNSC actually makes their life substantially easier than NRC certification. Its one thing to offer an easier certification path, but until a vendor actually gets final approval, we can only hope that path will actually be substantially easier. They can always invent pot holes along the way, like the NRC does all the time.
I suggest studying on public general MSR advantages. Those substantiate a lot of reasons why Terrestrial should succeed. Fingers crossed.
