Report assigns blame for Russian accident
A report by a government watchdog on the Aug. 17 explosion that paralyzed Russia’s 6,400 MW Sayano-Shushenskaya hydroelectric power plant, claiming 75 lives, says former chief executive of national electricity company Unified Energy Systems (UES) Anatoly Chubais is partially to blame for the conditions that led to the tragedy.
Russian Prime Minister Vladimir Putin ordered an investigation of the accident at Russia’s largest hydropower plant, saying any attempt to skimp on safety would be deemed “criminal.”
The report, prepared by industrial safety watchdog Rostekhnadzor and obtained by Interfax, partially blames such conditions on five others, including Deputy Energy Minister Vyacheslav Sinyugin.
The other four are Boris Vainzikher, general director of the TGK-1 generating company and a former technical director of UES; Valentin Stafiyevsky, head of the RusHydro generating company’s South division; Anatoly Dyakov, corresponding member of the Russian Academy of Sciences, who in 2000 headed the commission that gave the go-ahead to the plant being put in service; and Igor Yusufov, today a senior diplomat and between 2001 and 2004 energy minister.
Rostekhnadzor also named 18 members of the plant’s staff whose duties, the watchdog claimed, included accident prevention. Among them is RusHydro acting chief executive Vasily Zubakin.
The list also includes six other top managers of RusHydro. They are Boris Bogush, head of the company’s Production Business Unit; Timur Yusupov, deputy and operations director; Nikolai Dorofeyev, head of technical inspection; Timur Khaziakhmetov, chief of operations and modes management; Roman Klochkov, head of planning of repairs, technological re-equipment and modernization; and Alexander Toloshinov, head of the Siberia division, who was general director of Sayano-Shushenskaya from 2002 to 2006.
The 18-name list also includes former Sayano-Shushenskaya Director Nikolai Nevolko, some of his former deputies and heads of Sayano-Shushenskaya divisions, and Anatoly Konovalov, deputy head of Rostekhnadzor’s branch for the Siberian Federal District.
Scottish and Southern work to repair Glendoe after rockfall
Scottish and Southern Energy (SSE) is repairing a tunnel at its 100-MW Glendoe hydroelectric plant, which was damaged during a rockfall earlier this year.
Falling rocks caused a partial blockage in the tunnel that carries water to the power station. The turbine in the power station was not damaged in the rockfall, according to a statement from the company. The 100-MW plant, located on Loch Ness, began producing power in 2009 and is Scotland’s biggest producer of hydropower.
SSE would not say when the plant would resume production. The rockfall occurred near the top of the tunnel that carries water from the reservoir to the power station. Personnel drained the tunnel to allow investigators to assess the damage.
