Operation, test, research and development of the High Temperature Engineering Test Reactor (HTTR) (FY2013)

Department of HTTR

The High Temperature Engineering Test Reactor (HTTR) constructed at the Oarai Research and Development Center of the Japan Atomic Energy Agency (JAEA) is the first high-temperature gas-cooled reactor (HTGR) in Japan which is a graphite-moderated and helium gas-cooled reactor with 30MW of thermal power. In fiscal year 2013, we started to prepare the reactor installation application for the HTTR to prove conformity with the new research reactor's safety regulatory requirements taken effect from December 2013. We had been making effort to run the HTTR which was stopped since the 2011 in which the Pacific coast of Tohoku Earthquake (2011.3.11) occurred. This report summarizes activities and results of HTTR operation, maintenance, and several R&Ds, which were carried out in the fiscal year 2013.
