SOLUTION: The quantity of flow of supply water for a reactor pressure vessel, its enthalpy, and the enthalpy of a cooling material at the entrance of the core are measured to assume a carry-under rate, and each measured value and a hypothetical value are inputted to a computing means. Through the use of an energy balance expression at the exit and entrance of the core, the quantity of flow of the core is computed. On the basis of the quantity of flow of the core and the quantity of flow of supply water, exit quality is computed. On the basis of the exit quality and the quantity of flow of the core, a carry-under rate is computed from the correlating expression on the carry-under rate. The carry-under rate is compared with the hypothetical carry-under rate, and the computation is repeated until the difference between them becomes of a specific value or less. The carry-under rate when the difference becomes of the specific value or less is adopted to acquire the quantity of flow of the core.

摘要： PROBLEM TO BE SOLVED: To reduce the pressure loss coefficient of an orifice of fuel support metal in a boiling water reactor without degrading reinforcement effects by a reinforcement beam of a core support structure plate having a perpendicular reinforcement beam to the utmost.
SOLUTION: Each of reinforcement beams 3 and 4 of the core support plate of a boiling water reactor is perpendicularly assembled and the thickness of one reinforcement beam 3 is formed thinner than the thickness of the other reinforcement beam 4. Because of the difference in thickness of each reinforcement beam 3, 4, flow areas S
1 and S
2 in the left and the right of the boundary of a broken line connecting a corner where the reinforcement beams 3, 4 cross and the center of the orifice 2 of the fuel support metal 1 facing the corner become imbalance. As the flow paths around a control rod guide tube 9 inserted between each reinforcement beam 3, 4 become asymmetric on the broken line, and the flow into the orifice 2 of the fuel support metal 1 is simplified, pressure loss in the reactor core is reduced.
