The Nuclear Regulatory Authority in Slovakia said the expected completion of a third block at the Mochovce nuclear power plant has been delayed by a year to November 2017.
Ukraine increased its purchase of natural gas imports from Slovakia by 41 percent on Tuesday, boosting its storage supplies, transport monopoly Ukrtransgaz said.
Cash-strapped Ukraine is now buying most of its natural gas from Slovakia after halting imports from Russia three weeks ago due to a pricing dispute.
It was unclear whether the increase on Tuesday was due to price factors or other reasons.
Ukraine will take about 21 percent more gas from Slovakia to boost deliveries to underground storage after the country suspended imports from Russia over a pricing dispute, transport monopoly Ukrtransgaz said on Friday.
Ukraine plans to import 16.5 million cubic metres (mcm) of gas on Friday from Slovakia, up from daily imports of 13.6 mcm so far this month, a spokesman for the company said.
He said Ukraine pumped 27 mcm of gas per day from July 1-9 and collected 12.2 billion cubic metres of gas in reserves as of July 10.
