"Thousands more cracks found in Belgian nuclear reactors: Belgian regulatory head warns of global implications"

Entergy's Palisades atomic reactor, on the Lake Michigan shore in Covert, MI, has the worst embrittled RPV in the U.S., vulnerable to catastrophic failure due to PTS.As revealed in a new report from Greenpeace Belgium, micro-cracking in Belgian atomic reactor pressure vessels (RPV) due to hydrogen flaking could be a global problem going undiagnosed, simply because nuclear utilities and government regulators haven't done the needed testing. Belgium's nuclear regulatory agency has issued "a statement confirming that the additional tests conducted in 2014 revealed 13,047 cracks in Doel 3 and 3,149 in Tihange 2," as reported in Greenpeace Belgium's press release.

Embrittlement can lead to RPV failure due to pressurized thermal shock (PTS) in pressurized water reactors (PWRs). Beyond Nuclear, in coalition with Don't Waste MI, MI Safe Energy Future, and Nuclear Energy Information Service, has challenged the continued operation of Entergy Nuclear's Palisades atomic reactor in s.w. MI on the Lake Michigan shore (photo, above left), due to its worst embrittled RPV in the U.S. As reported by Greenpeace Belgium, a RPV breach due to PTS could cause a Loss-of-Coolant-Accident (LOCA), core meltdown, containment failure, and catastrophic radioactivity release.

However, Greenpeace Belgium's report warns that hydrogen flaking micro-cracking also impacts boiling water reactors (BWRs). Greenpeace Belgium's experts call for comprehensive testing of all atomic reactors worldwide, a position echoed by Belgium's top nuclear regulator. Belgium's two suspect reactors are shut; Greenpeace demands they remain so till the concern is addressed. Meanwhile, Palisades operates at full power.
