GE calls for shutdown tests at 88 reactors, citing earthquake safety

Singapore press site Asia One carried a Reuters story October 1:

GE Hitachi Nuclear Energy has warned operators of boiling water reactors (BWR) worldwide – including 35 in the US – that the plants could fail to shut automatically during an earthquake, potentially risking the safety of the power plant.

Fixing the problem involves mechanical changes to the plants:

GE Hitachi spokesman Michael Tetuan said most nuclear plants could fix the problem by replacing fuel channels, if needed. A typical boiling water reactor has between 400 and 800 such channels.

GE did not estimate what the cost of repairs would be or how long a reactor would have to be shut down in order to make the changes.

Reuters listed the affected U.S. plants:

US reactors included are Nine Mile Point Units 1 and 2; Fermi 2; Columbia; FitzPatrick; Pilgrim; Vermont Yankee; Grand Gulf; River Bend; Clinton; Oyster Creek; Dresden 2 and 3; LaSalle 1 and 2; Limerick 1 and 2; Peach Bottom 2 and 3; Quad Cities 1 and 2; Perry; Duane Arnold; Cooper; Monticello; Brunswick 1 and 2; Hope Creek; Hatch 1 and 2; and Browns Ferry 1, 2 and 3.

The problem is not limited to U.S. reactors:

The World Nuclear Association (WNA) website lists 53 BWRs outside the US, including 29 operating in Taiwan, Sweden, the Netherlands, Mexico, Japan, Italy, Germany and Finland.
