Power monitoring means for boiling water reactor

Creators

Description

Object: To eliminate the effect of noise and increase the response speed. Structure: Noise components obtainable by noise separation filter means from measured values of inlet flow rate, core pressure and other process quantities are coupled to respective transfer function quasi-circuits, whereby the contribution to the noise components of the neutron flux are obtained from the respective noise components. Since by coupling these portions to an adder a neutron noise component can be obtained, they are coupled to a subtractor for subtraction from the measured value of neutron flux, whereby the intended neutron flux signal can be obtained for display. (Kamimura, M.)
