Think of this page as a beginner’s guide, or a simple how-to manual.
This page doesn’t list every article published on this website. It lists those that provide a fundamental understanding of some of the most basic concepts any electrical engineer starting out in the nuclear power industry should master as soon as possible in their career.
Stepping through the articles listed here, in the order presented, will give you a basic understanding of how the NRC impacts every plant design. You will also develop working knowledge of the standard electrical engineering design tasks — and how to do them.

One of the first habits to build is checking the state of the industry each morning—and you can now do that right here. The US Fleet Status Dashboard shows the power level of every operating US reactor, updated daily from the NRC’s Power Reactor Status Report: who’s offline, who’s derated, and what the fleet is producing. It takes about thirty seconds to scan and will teach you the rhythm of the operating fleet—refueling seasons, coastdowns, forced outages—faster than any news feed.
Just as important for a design engineer: knowing what the NRC is changing. The NRC Rulemaking Docket Tracker pulls every proposed rule, final rule, and notice straight from the Federal Register, with open public comment periods counted down to the day. When a rule that touches your work is open for comment, that’s your window to be heard—and your early warning that the licensing basis you work to is about to move.
