高速実験炉「常陽」の昭和54年度定検において格納容器全体漏えい率試験に先立ち昭和54年8月末から12月初にかけて格納容器局部漏えい試験が実施され,判定基準を満足する結果が得られた。B種試験の合計漏えい率は,7,45110-3+-2,57110-4(%/day)C種試験の合計漏えい率は,4,02310-3+-2,77310-4(%/day)であった。(但し,統計処理法の結果である。)本書は,今回の格納容器局部漏えい試験の要領および結果について記述したものである。尚,結果については,従来の試験結果も記載した。

During the annual 1979 inspection of the JOYO experimental fast reactor, local leak tests were performed prior to the integrated leak rate test of the containment vessel itself. These tests, performed from the end of August to the beginning of December, were conducted to determine the leakage of the containment penetrations and auxiliary systems. The results of the tests were acceptable. [total leak rate of B test results 7.451102.57110(%/day)] [total leak rate of C test results 4.023102.77310(%/day)] This document describes the methods, procedures and results of these local leak tests. The results of past test are also described.
