CORTLANDT, N.Y. -- The Nuclear Regulatory Commission wants to make sure Cortlandt's Indian Point can withstand an earthquake, according to an article in Capital New York .
The NRC is requiring Indian Point to conduct a high-level earthquake risk report on both of its units.
Entergy had argued the risk to its Unit 3 reactor was overstated and that it would be burdensome to conduct seismic risk tests on both units, according to NRC documents. The assessment is expected to cost Entergy $10 million.
The NRC had previously determined that Indian Point was one of ten plants most in need of an earthquake risk assessment according to the story.
Indian Point is required to complete the evaluation by June 30, 2017.
Jerry Nappi, a spokesman for Entergy, said the company had previously conducted an engineering analysis demonstrating Unit 3 is protected from the strongest earthquake that could be expected in Cortlandt.
"We expect that the new seismic risk assessments recently directed by the NRC to be performed will demonstrate similar robust seismic capabilities for each unit," Nappi said.
Nappi said the analysis was not reviewed by the NRC and not credited for the review.
"Entergy had requested to stagger the reviews of IP2 and IP3 due to availability of technical experts in the industry," Nappi said. "But per the recent NRC letter, Entergy will simultaneously conduct seismic reviews for both units.
