Using boric acid poison rather than control rods promises lower capital cost, simpler maintenance, ready control of large reactivities, freedom from rod placement problems, and elimination of rod hot-spot factors in boiling water reactors. The amount of reactivity heid down by the acid varies, but is of the order of 3%. The boric acid is added to the reactor by dissolving in hot water, inserting into a special tank isolated from reactor pressure, injecting into the reactor water and flushing the tank, and circulating the reactor heater extensively to insure thorough mixing. Four methods are used to determine the concentration: calculation, titration, neutron absorption, and control rod motion. (W.D.M.)
