چکیده مقاله:

In this article fission chamber is used to measure the neutrons. By using an Aluminum cover, the detector has been tested in various radial and axial positions. The best position and distance for neutron detection have been obtained .The thermal power stability error has been calculated to be 5.005 percent but for the fission chamber is 0.8346. After performing calibration the system will be used as one of the reactor power display systems of TRR. Also, the reactor’s safety and variety of instruments improves and will increase self-sufficiency while providing redundancy and diversity. At the end of study the goal is to electronic system would be designed to count the number of fission chamber detector based on every second and at any time and any power, then calculated by multiplying the calibration factor and the ability to display a reactor power. Thermal power calibration system based on the system will be displayed.
