Implementation of Inverse Kinetics Method for HTR-10
As an advanced reactivity measurement method, the Inverse Kinetics Method (IKM) can measure the reactor reactivity in real time and on-line. IKM is mature in theory, but many skills are required to implement it. To implement IKM, the most important issue is to calculate the derivation of neutron signal, taking into account the inevitable random noise signal in the neutron signal. A digital filter and a cubic smoothing splines are developed to reduce the random noise signal level. A reactivity meter based on IKM is developed for 10MW High Temperature Gas Cooled Reactor (HTR-10). This reactivity meter is based on the Microsoft Windows for its advanced graphics interface, and commercial Analog to Digital converter card to interface with nuclear measurement system. Besides the function to online measure and display the reactivity, this meter is equipped with many functions to debug, calibrate, improve the IKM, such as recording neutron signal on-line, replaying recorded signal on-line to check the algorithm, embedded signal generator to simulate reactor reactivity transient with certain random noise signal mixed into the neutron signal.
