Abstract
PURPOSE: To reduce the thermal strain of a nozzle part and to intend to improve the safety of a reactor pressure vessel, by means of pouring water with temp. difference from the coolant inthe pessure vessel into an annulus part between a nozzle through which cold water is allowed to be entered and a thermal sleeve.
