HTTRでは炉心の動特性計算に必要な温度係数を測定するために、燃焼初期の平成11年及び平成12年に原子炉出力30kW及び9MWで温度係数測定試験を行った。その後、各種運転に伴い燃焼日数(EFPD)は設計寿命660日の半分を過ぎた約375日となった。そこで、温度係数の燃焼度依存性を評価するために、同出力で温度係数測定試験を行った。その結果を燃焼初期のデータと比較し、温度係数の燃焼特性を明らかにした。また、高い精度で温度係数を測定するために、炉心温度の制御の手法及び炉心温度の均一化の手法を確立した。

The temperature coefficient measurements of the HTTR have been carried out. In the beginning of the operation, temperature coefficients at the reactor power of 30 kW and 9 MW were obtained through 1999 to 2000. The operation days of the HTTR fuel reached 375 Effective Full Power Days (EFPD), which is over a half of design operation days (660 EFPD). The temperature coefficient measurements were conducted at the same power levels of 30 kW and 9 MW to evaluate burnup effect. Also, to measure temperature coefficient in high accuracy, technique of core temperature control and technique of core temperature homogenization were established.
