I work at a remote mine just south of the Arctic Circle, the perfect place for this type of thing as diesel-fueled power generation is just about the only way all these remote sites have reliable power.
The cost certainty any SMR company is going to need to sell a reactor is going to be extremely difficult for any company. The mines would be "happy" to go green, but even with carbon taxes, big up front CAPEX is going to be a hard sell for an unproven tech (SMR, not nuclear specifically). My guess is that offering selling the power (OPEX) as a fully managed and staffed service is the only way they're going to make this work.
I'd love to see us switch over, I'd also love to see it be sustainable and realistic. Let's hope for all of our sakes' someone figures it out, be it Nano, Global First, whomever.
