Validation of the COTENP Code: A Steady-State Thermal-Hydraulic Analysis Code for Nuclear Reactors with Plate Type Fuel Assemblies

Table 2

Temperature results obtained with the COTENP code for the IEA-R1 reactor at different power levels. Temperature results simulate measurement results at different locations of the IFA. The IFA is located at the (6,8) position. Inferred error from experimental results is + 0.25°C or + 0.5 %.
