North Anna nuclear power plant, owned and operated by Dominion Virginia Power (NYSE: D), will undergo a new seismic risk assessment.

The seismic “probabilistic risk assessment” or a seismic “margin analysis” will evaluate how structures and systems would respond during an earthquake.

The assessments will take a minimum of least three years to complete, an NRC spokesman said. Upon completion, the NRC will decide if plants require upgrades to equipment, systems and structures.

On August 2011, the two 980-MW North Anna nuclear reactors were knocked off line by a 5.8-magnitude earthquake.

David A. Heacock, president and chief nuclear officer of Dominion Nuclear said he was confident the plant would pass the assessment.
