Was kommt nach Fukushima?

WIEN – Seit dem verheerenden Unfall vor einem Jahr in Fukushima, Japan, ist die Atomkraft sicherer geworden. Und wenn Regierungen, Anlagenbetreiber und Sicherheitsbehörden nicht nachlässig werden, wird sie in den kommenden Jahren noch sicherer werden.

Der Unfall in Fukushima wurde durch ein Erdbeben und einen Tsunami von nie dagewesener Stärke ausgelöst. Aber die japanischen Behörden haben eingestanden, dass auch Fehlschläge menschlicher und organisatorischer Art eine wichtige Rolle gespielt haben.

So war Japans Atomregulierungsbehörde nicht unabhängig genug, und die Kontrolle des Anlagenbetreibers TEPCO war unzureichend. Am Standort in Fukushima war die Notstromversorgung, die für grundlegende Sicherheitsfunktionen wie die Kühlung der Reaktoren und der alten Brennstäbe entscheidend ist, unzureichend geschützt. Die Ausbildung für den Umgang mit schweren Unfällen entsprach nicht den Anforderungen. Am Standort und im ganzen Land fehlte es an Kapazitäten für den Katastrophenschutz.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.
