Neutron Irradiation of Electronic Materials at HANARO

Development and characteristics of the HANARO neutron irradiation facility for applications in the boron neutron capture therapy field.

The HANARO neutron irradiation facility for various applications in the boron neutron capture therapy (BNCT) field was developed, and its characteristics were investigated. In order to obtain the sufficient thermal neutron flux with a low level of contamination by fast neutrons and gamma rays, a radiation filtering method was adopted. The radiation filter was designed by using a silicon single ...

Visualization of the Internal Water Distribution at Pemfc Using Neutron Imaging Technology: Feasibility Test at Hanaro

The polymer electrolyte membrane fuel cell (PEMFC) is one of the most promising candidates for automotive applications due to its high energy conversion efficiency and absence of chemical pollution. PEMFC usually uses hydrogen and oxygen as fuel in order to generate electricity, and heat and water are generated as byproducts during that procedure. These byproducts create several problems couple...

A review on neutron shielding performance of nano-composite materials

Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...

Neutron irradiation of SmFeAsO1−xFx

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...
