Abstract
Recent nation-wide measures and actions taken in Korea after March 11, 2011 for enhancing nuclear safety and reducing public concerns are discussed by considering the lessons learned from the Fukushima Daiichi accidents as well as the amended National Safety Act, recently occurred historic earthquakes, and advanced light water reactor developments in Korea. In addition, recent R&D activities in the area of enhancing nuclear safety are introduced by focusing on the prevention and mitigation of severe accidents and the reduction of their environmental impact.
Kurzfassung
Die jüngsten landesweiten Maßnahmen und Aktionen, die nach dem 11. März 2011 in Korea ergriffen wurden, um die nukleare Sicherheit zu verbessern und die Bedenken der Öffentlichkeit zu verringern, werden unter Berücksichtigung der Lehren aus den Unfällen von Fukushima Daiichi sowie dem geänderten National Safety Act (NSA), den kürzlich erfolgten historischen Erdbeben und der Entwicklung eines fortschrittlichen Leichtwasserreaktors (ALWR) in Korea diskutiert. Darüber hinaus werden die jüngsten FuE-Aktivitäten zur Verbesserung der nuklearen Sicherheit beschrieben, wobei der Schwerpunkt auf der Verhütung und Minderung schwerer Unfälle und der Verringerung ihrer Auswirkungen auf die Umwelt liegt.
