A fire broke out on Sunday at a Moscow nuclear research center that houses a non-operational 60-year-old atomic reactor, emergency officials reported as Russia’s nuclear agency Rosatom said the blaze had not been accompanied by any open flames and posed no threat of a radiation leak.

A fire at the Stavrolen petrochemicals complex of the Lukoil group, Russia’s biggest independent oil producer, in mid-December is set to affect Russian market supplies of polyethylene and polypropylene.
The blaze, the site’s second major accident in just over three years, left eight workers injured, one of them in a grave condition. In 2008, an explosion and fire in the PP plant at the same Lukoil site killed three employees and left three more with severe burns.

This incident comes weeks after Stavrolen site, along with other group Lukoil subsidiaries, was the subject of an industrial safety inspection by the Russian state environmental, technical and nuclear regulatory agency Rostekhnadzor.

Russian oil company Lukoil Holdings said a fire Thursday at its Stavrolen chemical plant in southern Russia injured six people and partly disrupted production, according to Dow Jones Newswires. 

It was unclear when the fire, which broke out around 2 p.m. local time (1000 GMT), would be put out and to what extent it would affect production, a company spokesman said. 

The Stavrolen plant produced 684,000 metric tons of petrochemicals, mainly polyethylene, last year. 

Firefighters who are still trying to contain a fire at a chemical plant in the Urals city of Perm prevented an explosion on Tuesday, an emergencies service spokesman said.
A fire broke out early on Tuesday at a plant owned by Russia's largest petrochemicals holding, Sibur, and rapidly spread over 300 square meters.
"There are 30 fire engines and 108 firefighters currently working at the scene. No casualties have been reported," Valery Tiunov told RIA Novosti.
The company's spokeswoman confirmed the reports.
"Firemen are still struggling to bring the blaze under control. The cause is yet unknown. An official comment will be issued later in the day," she said.
