Fuel assembly
Description
A fuel assembly of a BWR type reactor comprises a plurality of fuel rods arranged in 9 x 9 matrix and water rods disposed between the fuel rods. The total of the cross sectional area of the water rods is determined as AW, the cross section of the fuel assembly is determined as ACH, the total of the cross section of the fuel rods is determined as Arod, and a wall thickness of the cladding tube of the fuel rod is determined as δ. The fuel assembly is constituted so that Arod/ACH and AW/ACH satisfy the following formulas. (Arod/ACH) ≤ -1.050(AW/ACH) +0.469, (Arod/ACH) ≤ (0.337δ + 0.1421)(AW/ACH) + 0.0804δ + 0.302, 0.98(0.2425δ + 0.384/(0.337δ + 1.192) ≤ (Arod/ACH) ≤ 1.02(0.2425δ + 0.384)/(0.337δ + 1.192), 0.98(0.0804δ - 0.167)/(-0.337δ - 1.192) ≤ (AW/ACH) ≤ 1.0(0.0804δ - 0.167)/(-0.337δ - 1.192).
