Since STNE has no properties unique to it, I suggest we give it one. When neutrons come into contact with STNE, the STNE becomes CLST. This will create a rock cycle in tpt:
CLST+WATR=PSTE
PSTE+heat=BRCK
BRCK+pressure=STNE
STNE+neutrons=CLST
*cycle repeats*
This shouldn't break any saves because neutrons and STNE currently do nothing. So no one would put them together unless this feature was added.
NOTE: molten STNE is still not affected by neutrons in any way.
Actually, it very well would. Melting of certain radioactive elements has a chance to produce STNE, in which case it'd be in contact with neutron emitters, and any saves that try to sort that out would break.
Actually when PLUT undergoes fission, it produces molten PLUT which; when cooled, turns into STNE. And this is not an efficient way to make STNE. Because the fissile PLUT also produces neutrons and URAN, isolating the molten PLUT is difficult. It also means you'll wind up with less finished product than raw material, so it's hardly worth the trouble. I see no reason why anyone would make a STNE factory in this way.

Well, the thing is, this'd ruin something of a neat mechanic: You can obtain the various radioactive elements using accelerated PROT, and as such, can obtain STNE using only a PROT laser and some setup. This *would* enable obtaining CLST this way, but it'd also break any saves that make use of this mechanic (i.e. some I have made)
Since proton collisions don't make STNE (they make NBLE, CO2, OXYG, PLSM, POLO, URAN, PLUT, and SING,) I can only assume that you've made PLUT out of protons, managed to separate the molten PLUT after fission, and then cooled it into STNE. So why wouldn't the STNE be well away from the neutrons?
Because PLUT is in the mix too, and PLUT is a neutron emitter. Simple as that.
Why not just cool the molten PLUT after all the neutrons have died down? Just a suggestion.
Well, I just got done writing an element that allows implementing this cycle more effectively, and avoids the weirdness that is NEUT reactions. It's currently PR'd, up to jacob1 if it ever gets added.
LAVA(STNE) + BCOL/COAL -> LAVA(SLCN)
LAVA(SLCN) + OXYG + (TEMP < 7719.45) -> LAVA(SAND / CLST / STNE)
Suggestion: add SLCN to PROT collision reaction
