Title: Void fraction measuring device
Inventor: SUGA TAKASHI
IPC: G01N23/12
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To make only fast neutrons passing through a hydrogen-contained liquid in a pipe neutron thermaligation by a moderator and detect them highly, precisely, and efficiently by providing a neutron detector, whose circumference is surrounded with the neutron moderator, in a position opposite to a radiation source in a pipe outside and arranging a neutron shielding material on the circumference of the pipe. SOLUTION: Energy of neutrons passing through a pipe 1 is distributed ranging from thermal neutrons to fast neutrons. A moderator 4 having an appropriate shape is arranged between a neutron detector 2 and the pipe 1, so that the fast neutrons passing through the pipe is moderated to thermal neutrons and the number of neutrons detected by the detector 2 is increased. A shielding material 5 is arranged on the circumference of the pipe 1 to prevent the fast neutron, which passes through except for the pipe 1, from reaching the detector 2 so that the sensitivity of the measuring number to gas rate (void fraction) is improved. This constitution can safely, inexpensively, and efficiently measure the void fraction using weak radiation sources which would not be objects of regulations.
