Cracks of up to 30cm have been found on the core shroud of the No.1 reactor at the idled Guosheng Nuclear Power Plant in Wanli District (萬里), New Taipei City (新北市), an Atomic Energy Council official has confirmed.

Civic groups yesterday warned against reactivating the plant.

In addition to unsettled concerns about cracked anchor bolts at the reactor, Green Consumers Foundation chairman Jay Fang (方儉) revealed that two cracks were found on welded parts of the core shroud, which Fang said could lead to disaster if the reactor is reactivated without repairs.
