I supported the paradigm of smaller reactors since about forever, while most people extolled the virtues of reactors for power being as big and centralized as possible.
Which makes for an irresistible target. I want my adversative to go that Big freaking reactor route - much cheaper to irradiate their land and take out as much power with as little expenditure as possible.
Now, looking at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fnric.inl.gov%2Fdome%2F. that thing has a strong SL-1 vibe.
Now, micro-reactor also has a mental image of a little room with a tiny reactor in it, in real life it will have some size to it.
Other strange things though. The one unit is claimed to have a 5 year life. If you have to replace the reactor at that short an interval, just use it full time, and cut ties to the grid. They promote it as emergency power. Starting and stopping the reactor based on the grid just seems weird.
The other thing is we have to remember that just because it has micro in the name, it is still a lot of energy trapped inside a small space. Micro sounds like a tiny thing, safe as can be.
One of the issues with these things is people - sometimes the manufacturers and contractors - get pretty complacent, and often hostile to regulations. See the recent issues in the Virgil C. Summer nuclear expansion project in South Carolina.
It's still an energetic genie we have trapped in a containment vessel, despite the cute name.
I've also said it is feasible to build very safe nuclear power plants - just an engineering issue. But the Engineers aren't the ones pulling the strings here, it is bean counters and MBA's. Can they be held at bay? I often think that while the plants can be safe, it's only if humans aren't involved.
I guess we'll see here, I've probably pissed everyone off with my analysis! 8^)
