KYIV, Ukraine (AP) — Belarus’ nuclear power plant, which went out of service a few days after it started operating, resumed producing electricity, officials said Thursday.

The country’s energy ministry said the reactor in the plant’s first unit is working at 40% of its 1,200-megawatt capacity and is sending electricity to the power grid.

The Astravyets plant went online in early November, but stopped producing electricity on Nov. 8.

Officials in neighboring Lithuania have long opposed the plant, citing safety concerns, and stopped buying electricity from Belarus when the plant started operating. The plant is about 40 kilometers (25 miles) southeast of Lithuanian capital Vilnius.

Lithuanian authorities said construction of the Russian-built and -financed plant was plagued by accidents, stolen materials and the mistreatment of workers.
