ABSTRACT:
A method and means for continuously introducing nitrogen into the primary coolant side of each steam generator during drain-down of a nuclear powered steam generating system is described, which will prevent the forming of a vacuum at the tops of the inverted U-tubes of the generators, thus to allow continuous drain-down of the water from within the tubes.
