A calibration circuit includes a selection unit, a power detector, an analog-to-digital converter and a calibrator. The selection unit is connected to the plurality of channels, selects two channels from among the plurality of channels, provides a test signal to the selected two channels, and receives a test result signal from the selected two channels. The power detector detects power of the selected two channels. The analog-to-digital converter performs an A/D conversion on an output of the power detector. The calibrator calibrates the phases and the gains between the plurality of channels based on an output of the analog-to-digital converter. One of the plurality of channels is set as a reference channel, phases and gains of remaining channels other than the reference channel among the plurality of channels are sequentially optimized based on the reference channel, and a phase and a gain of the reference channel is optimized.

The present invention relates to a connecting apparatus for a steam generator disposed between a steam generator and a flow mixing header to fasten the steam generator to the flow mixing header in a sealed manner, and an integral reactor including the same. Fastening the steam generator to the flow mixing header in a sealing manner includes: a base plate mounted on the flow mixing header having a through hole formed at the center thereof; and a steam generator connecting portion protruding along the circumference of the through hole in the base plate allowing an outlet of the steam generator to be inserted and fastened thereto. Since the connection for the steam generator is tightly fastened to the flow mixing header, leakage of a coolant therebetween is prevented, and since the steam generator is horizontally disposed in the flow mixing header, structural stabilization may be achieved.
