In High Temperature Engineering Test Reactor (HTTR) of 30MW, the generated heat at reactor core is finally dissipated at the air-cooler by way of the heat exchangers of the primary pressurized water cooler and the intermediate heat exchanger. To remove generated heat at reactor core and to hold reactor inlet coolant temperature to specified temperature, heat exchangers in main cooling system of HTTR should have designed heat exchange performance. In this report, heat exchange performance for ACL in main cooling system is evaluated with previous operation data, and evaluated values are compared with designed value. Moreover, heat exchange performance at full power operation is estimated for the air temperature. As the result, ACL has heat exchange performance removing generated heat at reactor core under the designe ACL inlet air temperature of 33

The HTTR (High Temperature Engineering Test Reactor) with the thermal power of 30MW and the reactor outlet coolant temperature of 850/950C is the first high temperature gas cooled reactor in Japan, which uses coated fuel particle, graphite for core components, and helium gas for primary coolant. In December 2001, the rated power of 30MW and the reactor outlet temperature of 850C was attained. JAERI received the certificate of pre-operation test, that is, the commissioning license for the HTTR in March 2002. This report summarizes operation, tests, maintenance, radiation control and construction of components and facilities for the HTTR as well as R&D on HTGRs for FY2002.
