Modular sections are pulled out and the first wall is replaced. Most of the section is put back in. You can pipeline this (like how any industrial process or digital processor works) to make the maintenance take a matter of days. The old material is low-level radioactive waste for less than a hundred years, then it's just metal. A 25 Bn USD 1 GWe plant could have 5 reactors and only need 3 to operate at max load continuously. A tritium leak is orders of magnitude less worse than a fission meltdown in terms of poisoning the water table. In the absolute worst case the exclusion zone lasts 100 years. A tritum or molten salt leak also trivial to contain compared to a fission meltdown. Ten feet of concrete. This is reflected in lower costs to build and relative ease to comply with regulation. Draw me the scenario where there is an explosion that cannot be contained by existing engineered solutions. Your most reliable product is FUD and misinformation born of confident ignorance. You really ought to stop until you know more.
