BRUSSELS — A dispute among Belgium, Germany and the Netherlands, centered on a pair of 40-year-old Belgian nuclear reactors roughly an hour’s drive from large cities across the border, is laying bare a growing European rift over nuclear energy.The nations are clashing amid deeply conflicting attitudes on a continent where carbon-free nuclear energy has fallen out of favor among some countries while others are doubling down on it. The split has paralyzed bureaucrats in the European Union and complicated efforts to forge a coherent long-term energy policy.
