Vermont Yankee is generating electricity again.

The nuclear power plant was off line for 25 days while it was refueled. Maintenance was also done during the outage.

The plant returned to service shortly before midnight Tuesday and officials say it will be slowly brought up to full power over the next few days.

Plant spokesman Larry Smith says 850 workers were brought in to supplement the plant's normal staff of about 600 during the outage.

One-third of the fuel rods in the reactor core were replaced.
