| 초록 |
For a heat analysis of the ITER ZrCo SDS beds, the thermal conductivity and specific heat of ZrCo powder (＜760µm, 0.6285 porosity) in air were measured as 0.154W/m/K and 381J/kg/K at room temperature by using NanoFlash Diffusivity (LFA 447) and Differential Scanning Calorimetry (DSC 204 F1). By using a geometric mean model, the thermal conductivity of ZrCo powder and ZrCo powder in hydrogen were calculated to be 3.143W/m/K and 0.524W/m/K. From the specific heat (381J/kg/J) of the ZrCo powder in air, the values of the specific heat of the ZrCo powder, ZrCoH1.5 and ZrCoH1.5 in hydrogen at room temperature were calculated to be 380.1J/kg/K, 518.0J/kg/K, 518.0J/kg/K, respectively. For the ZrCo chunk (2.3mm thickness, 8mm diameter, 3.5% porosity), the thermal conductivity was measured as 14.8W/m/K and the specific heat was measured as 389J/kg/K. |
