MOSCOW, October 28 (RIA Novosti) - Two of the three power units remain operational at the Leningradskaya nuclear power plant near Russia's second largest city of St. Petersburg after Saturday's emergency shutdown, the Russian nuclear power generating monopoly said.

NPP reactor No.2 was stopped after an emergency shutdown of its two turbo generators due to a 350-KV high-voltage cable short circuit, which the company said was caused by heavy winds.

Rosenergoatom said the reactor was working in a test mode after an overhaul in mid-October, but an emergency by no means was linked to this.

"An emergency situation was caused by a storm which hit the region," the spokesman said.

Rosenergoatom spokesman Ashot Nasibov hailed the NPP's emergency protection system, saying it managed the situation properly.

The company said in a statement that background radiation at the plant and surrounding areas is normal.

"There were no violations of secure usage of the Leningradskaya NPP. Background radiation at the plant and surrounding areas does not exceed the permitted level and corresponds to usage norms of the [plant's] reactors," the statement said.
