    • 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.

    • PURPOSE:To diminish dose equivalent rate at the inside and outside of a turbine building and to intend reduction of worker exposures by connecting an injection facility of carbon oxides to a feed water piping of nuclear reactor water feeding facility led to the inside of nuclear reactor pressure vessel from a turbine. CONSTITUTION:An injection facility 13 of carbon oxides is connected between a condensate demineralizer tower 8 and a feed water heater 9 of nuclear reactor water feeding facility. Since a C such as a CO2 from the injection facility 13, or a CO2 when an oxigen is injected, can be injected into feed water, by this constitution, an existence ratio of C such as a CO2 in the nuclear reactor water feeding facility, or a CO2 when an oxigen is injected, reduces consequently. And also, since a ratio of the CO2 or a CO when an oxigen is injected, increases, an activated C which is transfered to a main steam system, reduces accordingly. In this way, transfer of the C to the main steam system reduces and therefore dose equivalent rate in a turbine building also reduces and reduction of worker exposure can be well intented.
