It's using the energy of radioactive decay, not of a fission chain reaction. Where ChatGPT actually made a mistake was in ignoring the fact you can't get that energy out quickly enough. 1 gram of u-238 will release 19 million Calories of heat over the course of its existence but that will take many billions of years.

From the screenshot:

“The energy content of uranium-238 can be calculated based on its energy release per fission event. The energy release per fission event of uranium-238 is approximately 200 MeV (million electronvolts”

It's implied that the uranium sandwich comes with two slices of boron and mayo.
