ELI5: Why no nuclear *research* subs?

There was the NR-1 but it was decommissioned in 2005. It was extremely useful for longterm expeditions as a sort of mobile habitat. We now have a fleet of something like 71 nuclear subs, none of which have ever been used in battle. Can we really not spare *one* for scientific use?

They have been used on occasion.  They are **warcraft**, expensive ones, designed precisely for the mission of guarding a nation.

We can further lament that far too much is spent on weapons, that not enough is allocated to fundamental research for the betterment of mankind.
