Results of Calculations of the IAEA Benchmark Exercise on Steady-State Flow of Supercritical Water in a Heated Pipe

Abstract

The paper reports on a benchmarking activity carried on within the frame of the IAEA CRP on “Heat Transfer Behaviour and Thermo-hydraulics Codes Testing for SCWRs”. The paper contains the description of the Benchmark Exercise No.1 “Steady state Flow in a Heated Pipe” (hosted by OKB “GIDROPRESS”), the computational results of 10 participants getting by 11 codes, and preliminary conclusions.
