You may have misunderstood my focus, I agree that current nuclear reactors are designed with utmost safety and redundancy on top of redundancy. However, all those safety measures multiply feasibility, development and operating costs while also increasing the surface area of things that may be mismanaged/ignored/forgotten and not be immediately detected by external auditor/inspector if there is any at all.
As I have written previously:
Theorically, we all know and understand that following all the baseline protocols and maintenance schedules rigorously will keep a nuclear fission power plant working without environmental/health/safety issues for its entire entended life cycle.
Obviously, I absolutly hope and want nuclear technology to develop further. However, I do not think currently available options are cost effective and durably suitable for a world of increasing climate change perturbations. Governments, institutions and organizations will be stretched thin and thinner by multiple factors while increasing demands and sequences of societal and climatic events will test their ever changing priorities.
Nevertheless, one fission technology that may show promise in an increasingly turbulent world are small self-contained reactors. From my understanding, they are deployed in situ and buried providing energy to a nearby facility until its fuel has reached a predetermined end-of-life cycle. The self-contained reactor is then dug out and replaced by a new one while the EOL reactor is returned to be “recycled” and redeployed elsewhere. It seems simpler, hopefully also cost effective and a smaller safety concern overall.
As you have also pointed out with Fukushima having been slated to be decommissioned, political prerogative pushes thing far beyond what was intended. Be it old bridges collapsing way beyond their lifespan, or old submarines killing their crew from a fire onboard, or old fleet of gas guzzling trucks still belching a mix of burnt and unburned fuel particles, the list goes on forever. Even if we built the safest, most redundant, almost completely automated nuclear power plant that could last a hundred or two hundred years, how future governments deals with the decommission is entirety subject to their whims and changing political context.
And we can already witness hiccups of various degrees in every single countries since even before the pandemic, with changing political situation due to several interconnected factors in which climate change is a threat multiplier.
The thing is that people have a terrible level of patience in regards to long term benefits. For example, people constantly advocate for wind and solar, yet both only last ten years before having to be replaced. And as an alternative, natural gas is often proffered and employed, yet they only last about 20 years before being replaced. Nuclear fission plants have a typical lifespan of 60 years, with even existing plants having a theoretical lifespan of over 100 if the will to continuously refurbishing them exists. As things stand, we actually don’t have a single source of energy as cost efficient as nuclear fission as things stand aside from hydro. It’s just that it also has the single greatest initial investment cost as well, and won’t be paid back during the term of any administration that commissions it, as even in the best case scenario, they take 6 years to build, and can often take more than 10.
I do agree that SMRs are a great next step for nuclear as well as power generation in general, but they are also only a stepping stone. They only last 5 years or so before having to be replaced (as they generally cannot be refueled). But at the same time, we can survive using only stepping stones for the next few decades until a better alternative (aside from full scale fission) rounds the corner. I do hope fusion ends up being that power source, but traditional fission (as well as the newer advances in fission) are still one of the most cost effective, efficient, reliable, and safe. They just have a high political hurdle to face, as people fear what they don’t understand and there is no power source right now that people understand less than nuclear.
