Patent ID: 8116421

Claim:
An apparatus for inspecting and testing a startup range neutron monitoring system, the apparatus comprising: a neutron-flux detector that detects neutron flux existing in a pressure vessel of a nuclear reactor; a preamplifier that amplifies an electric signal output from the neutron-flux detector; a pulse measurement unit that counts times when electric signal output from the preamplifier exceeds a discrimination voltage; a Campbell measurement unit that measures mean square value of pulsation of the electric signal output from the preamplifier; a discrimination-voltage setting unit that applies the discrimination voltage to the pulse measurement unit; a voltage-setting unit that applies a voltage to the neutron-flux detector; an arithmetic processing unit that calculates an output power of the nuclear reactor based upon an output signal of the pulse measurement unit and an output of the Campbell measurement unit; an output unit that outputs data representing the output power of the nuclear reactor, calculated by the arithmetic processing unit; an inspecting/testing unit that sets the discrimination voltage and the voltage to be applied by the voltage-setting unit; and a transfer unit connected to the inspecting/testing unit that transfers data between the inspecting/testing unit and a computing device.
