摘要

In this report, detailed data which are necessary for the benchmark analysis of International Atomic Energy Agency (IAEA) Coordinated Research Program (CRP-3) on 'Heat Transport and Afterheat Removal for Gas-cooled Reactors under Accident Conditions' are described concerning about the configuration and sizes of the cooling panel test apparatus, experimental data and thermal properties. The test section of the test apparatus is composed of pressure vessel (max. 450degC) containing an electric heater (max. 100kW, 600degC) and cooling panels surrounding the pressure vessel. Gas pressure is varied from vacuum to 1.0MPa in the pressure vessel. Two experimental cases are selected as benchmark problems about afterheat removal of HTGR, described as follows, The experimental conditions are vacuum inside the pressure vessel and heater output 13.14kW, and helium gas pressure 0.73MPa inside the pressure vessel and heater output 28.79kW. Benchmark problems are to calculate temperature distributions on the outer surface of pressure vessel and heat transferred to the cooling panel using the experimental data. The analytical result of temperature distribution on the pressure vessel was estimated +38degC, -29degC compared with the experimental data, and analytical result of heat transferred from the surface of pressure vessel to the cooling panel was estimated max. -11.4% compared with the experimental result by using the computational code -THANPACST2- of JAERI.
