A quick video of how to get your reactor online and feeding power to the grid ! This is all based on my experience in-game, and my be inaccurate or plainly wrong ! I take no responsibility for any nuclear disasters !
My resistance banks were nearly bursting. Since you didn't close them in the video, I didn't close them either. But then I realized before it was too late. There is no need to keep them running all the time anyway. They should only be activated when demand exceeds production. For this reason, they should be kept under surveillance 👀.
