How do I use the fuel rod guide when I have it equipped? I tried holding right click but it didn't do anything.

Aside from that, if I were to put used fuel rods into fabricators or deconstructors, will the processes still complete after extinguishing the resulting fire?

Finally, is there also a way to bulk transport fuel rods safely? e.g. taking a thorium fuel rod from an abandoned outpost for your own sub or bringing multiple used fuel rods to dump in the ocean.
