How many steps of Bank D rod motion will be required to change power level from 5% to 18%? Assume that the full power Delta T from primary to secondary is 50 degrees F. Assume the moderator temperature coefficient is -5 pcm/degree F. Assume the Bank D rod worth is 5 pcm/step. Neglect fuel temperature changes. I dont even know what equations to use, nor can I find them anywhere. There is also NO textbook for this class, so everything is done via google search.
