> He took a dip in a pool with a functioning nuclear pile

xkcd published a What If? video about the consequences of swimming in a nuclear fuel pool: https://youtu.be/EFRUL7vKdU8

A pool containing nuclear fuel is different from a pool containing a running nuclear reactor with no other shielding, though.

A "pile" is not just a description of the thing, it is an actual formal term (old one!) meaning "reactor". So not just a bunch of radioactive matetial.

Here it is in written form. The punchline is worth the read/watch.
