摘要： PROBLEM TO BE SOLVED: To provide a method of determining the R-factor for a bundle of nuclear fuel rods in a nuclear light water reactor of the boiling water reactor type. SOLUTION: The R-factor is a factor that accounts for the weighted local power influence on a fuel rod. A local R-factor (R i (z)) is determined for each fuel rod (i) in the bundle and for each of a plurality of levels (z) in an axial direction. The individual axial heat generation profile for a certain fuel rod (i) is taken into account when determining the local R-factor (R i (z)) for the fuel rod (i). A processor configured for automatically determining the R-factor, a computer program product, a method of determining the critical power for a bundle of fuel rods, a nuclear energy plant, and a method of operating a nuclear energy plant are further provided.

摘要： PROBLEM TO BE SOLVED: To provide a new method having high practicability for measuring an axial-direction void fraction distribution. SOLUTION: Concerning an irradiated fuel assembly irradiated by neutrons in a nuclear reactor, radiation of the first group caused by a radioactive nuclide generated by neutron capture by a heavy nuclide, and radiation of the second group comprising a fission product not subjected to a neutron capture reaction after being generated by the fission are measured. Supposing that the measured radiation intensity A of the first group is proportional to the exponential (α) power of a combustion degree E, the equation: A=a×E**α (a is a proportional constant) is set up, and supposing that the measured radiation intensity B of the second group is proportional to the combustion degree E, the equation: B=b×E (b is a proportional constant) is set up. In the equation: a/a 0 =(A/A 0 )×(B 0 /B)**α×(b/b 0 )**α, which is acquired from an equation determined by raising both side members of the equation of the radiation intensity of the second group to the α-th power, taking the ratio thereof to the equation of the first group, and erasing the factor of the combustion degree, the characteristic wherein a/a 0 is dependent on the axial-direction void fraction distribution inside the nuclear reactor is utilized, and A/A 0 and B 0 /B are measured, to thereby determine the axial-direction void fraction distribution through a calibration curve determined separately.

摘要： PURPOSE:To provide a pressure tube reactor which can be controlled properly by promptly detecting boiling no matter in which pressure tube it occurs at the start of the reactor, and, should piping be ruptured, promptly detecting the ruptured parts. CONSTITUTION:A pressure tube reactor, in which fuel 5 is enclosed in a pressure tube 1, and a coolant 4 is allowed to flow into the pressure tube 1 from an inlet tube 7 and flow out of an outlet tube 8, has an inlet flow meter 9 installed between the lower end of the fuel 5 and the inlet tube 7 and an outlet flow meter 10 installed between the upper end of the fuel 5 and the outlet tube 8. Flow rate signals obtained from the flow meters are fed to monitoring equipment 13 and reactor controllers (A), (B) via a computing unit 11 and a judging unit 12, and the reactor is controlled by these two reactor controllers.
