  • Benchmark Analysis of SFP Spray Cooling Test with MAAP Code

抄録

<p>In order to validate a spray cooling model for spent fuel pool (SFP) in the severe accident code “MAAP”, benchmark analysis of SFP spray cooling tests was conducted with MAAP ver. 5.04. In a current spray cooling model in MAAP code, spray water entered into a fuel assembly flows down uniformly on the surface of fuel pins and fuel racks in the form of liquid film and cools the fuel pin from its top to the bottom. As a result, the current MAAP model causes effective cooling and leads to the tendency of overestimation of spray cooling rate comparing to the measured data.</p>
