Latest Patents

William A. Stewart holds a patent for a Passive Containment Cooling System. This system utilizes a naturally induced airflow and a gravity flow of water over the containment shell that encloses a reactor core. The design aims to cool reactor core decay heat in two stages. During the initial phase, when core decay heat is at its peak, the combination of water and air flow provides adequate evaporative cooling. Heat from within the containment is transferred to the water flowing over it. The water is then heated and evaporated, subsequently removed by the airflow. After approximately three to four days, when core decay heat decreases, airflow alone is sufficient to cool the containment.
