Entergy takes Arkansas Nuclear One Unit 1 offline for refueling

Entergy (NYSE:ETR) confirmed Jan. 27 that it took its Arkansas Nuclear One Unit 1 facility offline early Jan. 25 for a planned refueling and maintenance outage.

Arkansas Nuclear One Unit 2 remained operating at 100% generation, according to the latest reactor status report from the Nuclear Regulatory Commission (NRC).

ANO Unit 1 has a nameplate capacity of 903 MW, according to GenerationHub records. Unit 2 has a somewhat larger capacity at 943 MW. Unit 1 entered commercial service in 1974 and Unit 2 in 1980.

Both are pressurized water reactors located in Russellville, Ark.

The most recent refueling outage at ANO Unit 1 started in March 2013 and lasted into August of that year, according to data released recently by the Nuclear Energy Institute (NEI). Unit 2 had a 45-day outage last year that ended in June, according to the NEI data.

This past summer, NRC issued two “yellow” findings of substantial safety significance to the plant following NRC’s investigation of a 2013 fatal heavy equipment accident at the station.
