摘要： PROBLEM TO BE SOLVED: To provide a device and a method for detecting the boiling in by-pass areas because boiling might occur in the by-pass areas between fuel channels constituting a core in case of the decrease in the flow rate of coolant for some reason in a boiling water reactor.
SOLUTION: A data processing means 3 obtains evaluation index data on the basis of the power spectral density of output signals of an existing in-core neutron detector (LPRM) 54d. Moreover, the correspondence of the evaluation index data to the by-pass areas are stored in advance as boiling determination reference data in a reference data storage 5. A boiling determination means 6 compares the evaluation index data with the boiling determination reference data to make the determination on the boiling in the by-pass areas.

摘要： PROBLEM TO BE SOLVED: To obtain a method for measuring void rates which makes it possible to easily measure a void rate inside a core and an effective void rate on the outer periphery in a boiling water reactor with an existing actual device without installing any new jigs for measurement, producing distortions of neutron flux or output or causing the loss of the reactivity in the core. SOLUTION: Given a threshold energy causing an activation reaction by fast neutrons whose energy is a certain value or higher, the reactivity ratio[(F)/(S)] of the fast neuron activation reactivity (F) of fast neutron threshold reaction nuclides to the slow neutron activation reactivity (S) in the activation of slow neutrons consisting of thermal and epithermal neutrons through the absorption of them is measured to a void rate measurement position (x) and a position (0) of a known void rate. Then, the reactivity ratio R=[(Fx)/(Sx)]/[(Fo/So)] of the reactivity ratio (Fx)/(Sx) of the void rate measurement position (x) to the reactivity ratio (Fo/So) of the position (0) of the known void rate is determined and is used together with a calibration curve found otherwise to determine the axial distribution of void rates of the reactor.

摘要： PURPOSE: To prevent depressurization boiling without loading on an operator when the output of a pressurized water nuclear reactor is lowered. CONSTITUTION: The temperature of a first coolant in the vicinity of a reactor core 2 is detected by a coolant thermometer 5 and the pressure of the first coolant is detected by a coolant manometer 6. When an output reduction operation is executed by a operating device 9, a boiling curve calculator 7 judges whether there is the possibility of occurring the depressurization boiling of the first coolant in the vicinity of the reactor core 2 based on the detection result of the coolant thermometer 5 and coolant manometer 6 and a boiling curve of the first coolant. The boiling curve calculator 7 outputs an alarming signal to the operating device 9 by using a signal output device 8 during the existence of the possibility of the reduction boiling is predicted. In the operating device 9, the output reduction operation is stopped during the alarming signal is outputted.
