Axial void fraction distribution measurement method and neutron multiplication factor evaluating method |
| abstract |
A first intensity A z expressed as A z =a z ×E α , a first reference intensity A 0 expressed as A 0 =a 0 ×E α , a second intensity B z expressed as B z =b z ×E, and a second reference intensity B 0 =b 0 ×E, are evaluated. The first intensity and the first reference intensity are of radioactive nuclides generated by a neutron capture reaction of a heavy nuclide or a fission product nuclide. The second intensity and the second reference intensity are of radioactive fission product nuclides except nuclides generated by a neutron capture reaction. The reference intensities are measured where the void fraction is known. Also a correlation curve of (a z /a 0 ) and a void fraction is evaluated. Finally an axial void fraction distribution is evaluated based on the value of (a z /a 0 ) and the correlation curve. |
