Entergy nuke plant in NY back in service BUCHANAN, N.Y. (AP) - An Entergy Corp. nuclear plant in the New York suburbs has been reconnected to the electrical grid after a day and a half offline. Entergy Nuclear says the Indian Point 3 reactor was put back into service Thursday afternoon. It was disconnected from the grid Wednesday morning after gases built up in a transformer. The transformer had been used to take electricity from the main generator, change the voltage and power some pumps and motors at the plant. Entergy spokesman Jerry Nappi says that with the transformer under repair, those pumps and motors are now using outside power. In November 2010, a transformer explosion caused a 17-day shutdown of Indian Point 2, the other reactor at the site in Buchanan, about 35 miles from Manhattan.
