Thermal-Hydraulics Engineer

Also called: Reactor Safety Analyst

Simulates how water, steam and heat move through a reactor, including what happens in an accident.

A day in the life

You run computer models of a pipe break and show that the backup cooling keeps the core safe. Regulators review your analysis line by line.
