This sort of application is where one of the smallest Small Modular Reactor designs would theoretically be great, but nobody is offering a commercial SMR yet. All SMR designs are still in the R&D phase. The smallest commercially available power reactor designs start at hundreds of megawatts, which is far larger than the 17 MW the campus needed.
They both sound simple on paper but in reality they'd probably cost more than the natural gas pipeline Fairbanks wishes it had.
When public institutions engage in infrastructure projects they need to do a massive amount of work to ensure their ass is completely and totally covered from every angle. Trying to do something off the beaten path, like go nuclear, is a recipe for lengthy court battles and cost overruns. Blazing that trail is best left to the wealthy universities. Modern micro scale nuclear reactors and power stations built out of surplus hardware would be cool but there's a massive cost disadvantage for the first mover.
