Summary:An in-core structure test section (T2) in Helium Engineering Demonstration Loop (HENDEL) simulates a part of the core bottom structure with the same scale as that of a High Temperature engineering Test Reactor (HTTR) designed in Japan Atomic Energy Research Institute. Testing devices, such as an inner vessel, flow regulators, region heaters and flow rate measurement blocks, were fabricated so that T2 test section could be tested under the same conditions as those of HTTR. Design problems were solved by element tests of the devices during their fabrications. Testing devices were finally confirmed to have required performances in helium gas conditions of 4.0 MPa and 1, 000°C through preliminary test of HENDEL operation.
