چکیده انگلیسی
To visualize boiling two-phase flow at high heat flux by using neutron radiography, a new neutron radiography facility was developed in the B-4 beam hole of KUR. The B-4 beam hole is equipped with a supermirror neutron guide tube with a characteristic wavelength of 1.2Â Ã
, whose geometrical parameters of the guide tube are: 11.7Â m total length and 10Â mm wide Ã74Â mm high beam cross-section. The total neutron flux obtained from the KUR supermirror guide tube is about 5Ã107Â n/cm2Â s with a nominal thermal output of 5Â MW of KUR, which is about 100 times what is obtainable with the conventional KUR neutron radiography facility (E-2 beam hole). In this study a new imaging device, an electric power supply (1200Â A, 20Â V), and a thermal hydraulic loop were installed. The neutron source, the beam tube, and the radiography rooms are described in detail and the preliminary images obtained at the developed facility are shown.
