Entergy to replace water seals at Indian Point Unit 3

Entergy (NYSE:ETR) has taken the Indian Point 3 nuclear plant in Buchanan, N.Y., out of service for a planned maintenance shutdown to replace two water seals that sit between the lid of the reactor and the reactor vessel.

The facility was listed at zero power early Sept. 16, according to data from the Nuclear Regulatory Commission (NRC). As of early Sept. 16, seven of the nation’s 99 commercial nuclear units were offline, according to NRC.

Entergy operators have been monitoring slight water leakage by the seals over the last several weeks and are acting “conservatively and proactively to replace the seals out of an abundance of caution,” the company said in a news release. There was no threat of release of radiation to the environment and no threat to public or worker health or safety as a result of this issue, Entergy said.

Unit 2 is currently operating at full power and has been online for 547 continuous days. Unit 3 had been online for 68 continuous days when Entergy announced the maintenance outage on Sept. 14.

Indian Point Units 2 and 3, together generate roughly 2,000 MW of electricity for homes, business and public facilities in New York City and Westchester County, N.Y.

Both units are pressurized water reactors (PWRs) commissioned in the 1970s. Both are engaged in prolonged license renewal cases before the NRC. Indian Point 3 was the site of a May transformer fire that caused the facility to be removed from service for more than two weeks.
