A boiling-water nuclear reactor vessel comprises a cylinder of length 20 m and diameter 5 m with hemispherical end caps. The thermal power generated in the reactor is 1800 MW and the pressure is 7 MPa. 2% of the mass of water in the reactor is vapour, and the remainder is liquid. Assume the temperature is uniform. In an accident, the water flow stops. Control rods are inserted and thermal power drops to 1% of the normal level. How long will it take for pressure in the vessel to reach 15 MPa?
