Abstract

Abstract

This paper introduces the AFAL analysis methodology for nuclear power plants and its application in the demonstration of the extension of instrument calibration interval.The paper discusses the technological means and implementation.By the analysis of instrument drift,the feasibility for the extension of the instrument calibration interval is demonstrated.On the premise of nuclear safety,the interval of fuel reload overhauling in the nuclear power plants can be prolonged.
