After the accident at the Fukushima Dai-ichi (1F) Nuclear Power Plant (NPP), the Nuclear and Industrial Safety Agency gave the provisions, “Ensuring reliability of instrumentation during accidents” and “Enhancement of surveillance capability of the status of the NPPs”, in March 2012. In response to these provisions, we have developed a high heat resistance and a high-temperature resistance type MI cable with radiation resistant as a cable for measurement in the nuclear reactor at the time of a sever a...

Domestic light water reactors are expected to restart sequentially after given permission in condition to meet the new regulatory requirements. Since several safety related systems were added to the plants through the process of the new regulatory requirements, the numbers of components to be inspected, which is already a large amount, will increase even more after the restart. Effective measure will be required to command maintenance activities by reasonably assigning limited resource. The authors hav...

1.緒言 東日本大震災以降、規制要件の強化や電力市場の自由化等、電力業界を取り巻く環境は大きく変化し、高品質かつ低廉な電力の供給が求められる。電気事業者としては、設備の安全(信頼)性の維持・向上と効率的な業務 運営の両立のため、保全の最適化に取り組んでおり、保全の有効性評価をこれまで以上に機能させていくことが重要となる。 今回、保全の有効性評価をより実効的に行う取組みとして、関西電力グループで実施した保全最適化の活動を紹介する。 2.保全最適化の取組みの概要 関西電力の原子力発電所における保全活動において......

X-Ray diffraction spots from coarse grains of austenitic stainless steel, SUS316L, were measured with an area detector. The error of the measurement of the diffraction angle was investigated.“ -method ”was proposed to solve the error due to the position of the coarse grain. However, the -method was not effective in solution of the error. A double-exposure method (DEM) was proposed as the measurement without error due to the position of the coarse grain. The DEM did not solve the error due to the divergen...
