Workload: Salaried for 40 hours a week, but a more realistic number is 50-60. Managers typically have 10 hour days that may limit employee oversight.
Additional Duty: Responsible for standing emergency response teams that limit your weekend activities (no drinking, travel limitations). Outage coverage means 12hr shiftwork for ~1 month per year.
Regulation: If you want to "change the world" then you need to work for Elon Musk. The NRC and government regulates everything in the nuke power industry. Conservative thinking and risk management are mandatory cultural adaptations.
