本報告書はHTTRの起動試験及び出力上昇試験時の炉物理試験結果について記載したものである。この試験は高温ガス炉の性能と安全性を確認する目的で行われ、臨界近接,過剰反応度,炉停止余裕,制御棒価値,反応度係数,中性子束分布及び出力分布が測定された。測定結果と計算結果から予期していた炉心性能と必要な炉心安全性能を有することを確認した。

This paper describes the results of core physics test in start-up and power-up of the HTTR. The tests were conducted in order to ensure performance and safety of the high temperature gas cooled reactor, and was carried out to measure the critical approach, the excess reactivity, the shutdown margin, the control rod worth, the reactivity coefficient, the neutron flux distribution and the power distribution. The expected core performance and the required reactor safety characteristics were verified from the results of measurements and calculations.
