“…The temperature of cooling water in the reactor in-core is about 40 ∘ C, and the heat transfer coefficient at the outer surface of the external tube is 30.3 × 10 3 W/m 2∘ C, which is experimentally determined [13]. The two conditions above are considered as boundary conditions in the FE analysis, and the symmetric conditions are also applied for the symmetric axes of the 2D models.…”

Irradiation tests of materials at HANARO have usually been conducted using a standard capsule at temperatures of about 300 ∘ C for irradiation of materials used at PWR. Thus, the standard capsule uses aluminum as the specimen holder, which acts to dissipate the thermal energy. Future nuclear systems such as a VHTR and SFR require the irradiation tests at a relatively high temperature. As an alternative to aluminum which has been used as the thermal media in a standard material capsule, the characteristics of liquid metals such as NaK and LBE are reviewed. The temperatures of the capsule are affected by the variation of parameters such as the gap and wall thickness of the container. In particular, the external gap is most important in determining the temperature of the specimen. LBE raises the temperature of the specimen higher than NaK at the same configuration of the capsule. Thus, LBE can lessen the gap of the parts and reduce the vibration for a stable long-term test in reactor.

“…The temperature of the cooling water in the reactor in-core is about 40°C, and the heat transfer coefficient at the outer surface of the external tube is 30.3 · 10 3 W/m 2°C , which is experimentally determined [8]. The two conditions above are boundary conditions in the FE analysis, and adiabatic conditions are applied for the symmetric axes of the 2D and 3D models.…”
