1. はじめ資源の乏しいわが国にとって、原子力は電力の安定 供給の確保と地球温暖化対策の面で優れたエネルギー であり、安全の確保を大前提に、原子燃料サイクルを 確立し、原子力発電を基幹電源として推進していくこ とが重要である。しかしながら、電力小売自由化の進展、原子力にお ける新たな安全規制の導入、そして近年の度重なるト ラブルや不祥事により社会からの信頼が揺らぐなど、 原子力を取り巻く環境は大きく変化してきている。このような情勢のもとで、原子力の特性を十二分に 発揮させるためには、プラントメーカーや電力......

Taking the accident response at Fukushima Daiichi Nuclear Power Plant as an opportunity, we have tried not to damage as much as possible against various types of risk. Furthermore, even if damage occurred, it has been regarded as important to have the ability to recover(resilience). As MHI possessing technologies that can contribute to voluntary safety improvement of nuclear power plants, there are Multiple Radiological Emergency Assistance System for Urgent Response(MEASURES), VISION, and the like. Also, t...
