Void Fraction Measurement Method using Neutron Radiography

摘要

The present invention relates to a measurement method using the neutron porosity chwalyoungbeop radiation, and more particularly, attenuation characteristics of the neutron using that the exponential function, without blocking the flow of fluid inside the measuring object, the present invention relates to a neutron porosity measurement method using a radiation chwalyoungbeop one to be able to measure the porosity of the inside of the measuring object. ; Thus, the present invention includes a first step and to produce a reference sample; Placing a second step with a standard sample by installing a neutron radiography device; And a third step for performing a neutron radiography for the standard sample; Instead of the standard sample measured by placing the object at that position, and a fourth step for performing a neutron radiography; And a fifth step of obtaining a reference graph through the image processing of the standard sample; And a sixth step of obtaining the thickness of the working fluid by measuring the intensity of light of each pixel for the image of the measurement object; Provides a neutron porosity measurement method using a radiation chwalyoungbeop which comprises the thickness of the working fluid in the seventh step of calculating the porosity is based.
