PURPOSE: A digital excore nuclear instrumentation system having thermal power automatic amending function is provided to shorten maintenance time. CONSTITUTION: An amplifier(100) is installed in the upper, the middle and the lower part of a reactor wall. The amplifier amplifies the pulse and the current generated by nuclear fission. A signal processing unit(200) changes the input value received from the amplifier to a digital value. A signal processing unit automates the operation of a nuclear instrumentation system. A thermal power automatic amending unit(300) transmits a heat power correction value to the signal processing unit. [Reference numerals] (200) Signal processing unit; (300) Inputting a heat output measuring correction value(processing by communication); (AA) Upper part; (BB) Center; (CC) Lower part; (D1,D2,D3) Pulse amplifier; (E1,E2,E3) Linear amplifier; (FF) Containment penetration hole; (GG) Analog input card; (HH) Processor board; (II) Digital output card; (JJ) Digital input card; (KK) Analog output card
