I have not figured out what the nuclear reactor is in your whazit yet.
While I was attending the University of California at Irvine (UCI) they installed a nuclear reactor. Two things surprised me.
1. Lack of security. I went into the building at least once a week to observe what they were doing. Nobody challenged me.
2. Once they got the pool full of water the water glowed an eerie blue. The blue glow was caused by Cherenkov radiation.
I was told the radiation samples for our experiments were made in the school's reactor. I remember testing for types of radiation by covering the samples with paper and aluminum. Alpha particles were blocked by paper. Beta particles were blocked by aluminum. If it got through paper and aluminum it was Gamma radiation.
Here is a picture of the UCI TRIGA reactor.

Cherenkove radiation fascinated me at first because Dr. Teller told me that Cherenkov radiation results when a charged particle, most commonly an electron, travels through a dielectric (water) medium with a speed greater than that at which light propagates in the same medium. I thought our TRIGA was producing particles that exceeded the speed of light.
