Estimation of fuel temperature through a burn-up period in HTTR; For 850 $^{circ}$ C operation

Tochio, Daisuke ; Shinohara, Masanori ; Fujimoto, Nozomu

The HTTR is block-type high-temperature gas-cooled reactor composed graphite-block piled-up structure. In the viewpoint of core structure, it is very difficult to measure fuel temperature of the HTTR directory. Therefore, power distribution is calculated by nuclear characteristics estimation code, and the fuel temperature is estimated by fuel temperature estimation code with obtained power distribution data in the HTTR. This report describes the estimation results of power distribution and fuel temperature for 850 $^{circ}$ C operation through a burn-up period.
