How nuclear reactors actually work — core management, neutron behavior, reactor physics and design, explained clearly by a working reactor engineer.
What boron control rods are actually made of, how PWR and BWR designs differ, and why a graphite-tipped rod turned Chernobyl’s emergency shutdown into a power surge — from a working reactor engineer.
Xenon-135 is the poison a reactor makes itself and it peaks after shutdown. Why that delays restart, what “xenon dead time” really means, and how operators manage it.
Every reactor is deliberately fed a “poison” — boron. A reactor engineer explains what neutron poison is, why boron is essential, and how it keeps a reactor under control.
