After more than two years of work to re-tension cables
within the walls of the Crystal River power plant, the facility’s owner
announced Tuesday that work has been temporarily suspended.
In a statement, Progress Energy indicated that the final
tensioning of tendons within the reactor building was stopped because of
additional delamination resulting from the repairs, and that the plant will not
restart in April as planned.
In what started as a three-month project, Progress shut down
the reactor for refueling and replacement of its steam generator in 2009. While
crews were making a hole in the reactor building to remove the steam generator,
they noticed a gap in the 42-inch thick walls. Progress determined that the
process of loosening the structural cables that reinforce the plant’s walls had
caused the gap.
Since then, the company has embarked on what a
spokesman once described as a “highly orchestrated,” multi-step effort to
retighten about 200 cables within the walls. In Tuesday’s statement on the
