SAFETY EQUIPMENT FOR SHIP REACTORS

Patent ·
OSTI ID:4843841

A nuclear reactor is mounted in a ship below sea level and is surrounded by a tight metal casing. The reactor with this casing is situated inside a radiation shield so that the inner surface of the shield and the outer surface of the casing form an interspace. This interspace may communi cate with the water of the sea by a plurality of normally closed channels, these channels being opened in the case of danger. The said channels are closed by valves which open in the case of loss of the energy actuating these valves. Two valves may be arranged in series in each channel, so that the valve situated near the reactor is a hydraulically actuated valve, while the valve near the exit of the channel into the sea water is an electrically operated valve. The said interspace inside the radiation shield forms with some of the said channels and the sea water outside the ship a natural circulation circuit for any attitude of the ship. (NPO)
