California’s Nuclear Power in Doubt

Despite calls for a resurgence in nuclear power, California could soon shutter its effort to keep the alternative energy going.

PG&E’s Diablo Canyon plant, the state’s last, has wound up in the crosshairs. As the Associated Press reported, “the company is evaluating whether to meet a tangle of potentially costly state environmental requirements needed to obtain renewed operating licenses.”

“The issues in play at Diablo Canyon range from a long-running debate over the ability of structures to withstand earthquakes — one fault runs 650 yards from the reactors — to the possibility PG&E might be ordered by state regulators to spend billions to modify or replace the plant’s cooling system, which sucks up 2.5 billions of gallons of ocean water a day and has been blamed for killing fish and other marine life.”
The fault in question has rattled nerves in the area and throughout the state. “Even before the twin reactors produced a single watt of electricity, the plant had to be retrofitted after a submerged fault was discovered 3 miles offshore during construction,” the wire noted separately. “That cleft in the earth, known as the Hosgri fault, has long been considered the greatest seismic threat to a plant that stands within a virtual web of faults. But new questions are being raised by sophisticated seafloor mapping that has found that the Hosgri links to a second, larger crack farther north, the San Gregorio fault.”

Increasing emissions

At the same time, the environmental implications of an end to nuclear power have also raised serious concerns. The last California plant to close, in San Diego county, shuttered amidst problems with its infrastructure. California’s public utility commission “approved a shutdown deal last year with the San Onofre plant’s co-owners, Southern California Edison and San Diego Gas and Electric Co., that assigned about 70 percent of the $4.7 billion shutdown bill to the firms’ customers,” as the San Francisco Chronicle reported. “The companies closed San Onofre after a January 2012 leak of radioactive steam revealed widespread damage to its cooling system.”
