  • January 24, 2011; The test of loss of forced cooling without the vessel cooling system operational(the loss-of-core cooling test, LOCC) in the HTTR was successfully completed under the condition of the reactor power of 9MW (30% of the rated power). To demonstrate the inherent safety features of HTGR in the case of LOCC, all of the primary gas circulators and additionally one out of the two reactor vessel cooling systems for decay heat removal were stopped from the 9MW steady-state operation. The primary coolant flow rate reduced to zero, and the reactor power decreased rapidly to zero from just after the gas circulators' stoppage. The LOCC test was continued for 6 hours, during which the increase in the vessel temperature and other reactor structures were confirmed within the conservative analytical results obtained prior to the test.
  • December 21, 2010; The first loss-of-forced cooling (LOFC) test using the HTTR was conducted. In the test, all gas circulators in the primary system were stopped from the steady operation under the reactor power of 9MW (30% of the rated power of 30MW). Zero flow rate of the HTTR primary system was kept for 12 hours. The reactor power decreased rapidly down to zero from just after the gas circulators' stoppage. Several hours later, the reactor attained re-criticality and the reactor was kept steady state of low power.
  • September 29, 2010; At the 2nd Japan-Kazakhstan Joint Public-Private Sector Economic Conference, Marubeni Utility Services, Ltd, Toshiba Corporation and JAEA made presentation in their joint authors concerning the present status of cooperation in the field of HTGR technologies between Kazakhstan and Japan.
