For those playing along at home, the 135-Xe half-life is a little over 9 hours, and reactor equilibrium after changing power levels/neutron flux is between 40 and 50 hours. Most of the 135-Xe in a reactor isn't directly created as a fission product; that only happens about .3% of the time. Most of it is created as a result of decays from 135-Te (t½ 19 seconds) and 135-I (t½ ~7 hours). All told, 135-Xe is created as a result of about 6% of fissions.

Thanks for the accurate update. I wondered where 14 hours came from.

The xenon pit explained in a minute. That's why you wait about 48 hours before restarting a stopped reactor. The worst that could happen is that the xenon burns up and the reactor is suddnly in a prompt supercritical condition. This is exactly what happened when Chernobyl blew up, the reactor went from almost zero to over 10GW in 30 seconds.😢

The Reactor Power production didnt spike until AZ-5 was pressed (it was pressed because it was part of the safety test, thats why)

@@onefor2that’s not entirely correct… the statement above is. The attempt to restart the reactor after it stalled was a known cardinal sin in reactor physics even back then. The rest are just another series of holes in the Swiss cheese leading up to the explosion of the core.

Nah just press Az5 what could go wrong?

Agree

Nice

Xenon is also a fuel for ion propulsion so when your reactor is off you use the xenon to power the thrusters 😮

I can’t tell you how much it bothers me to see people of influence running around with extremely dangerous software like TikTok on their phones…
