In addition to turbine 2, turbines 7 and 9 also suffered severe damage and were destroyed, while the turbine room roof and ceilings fell on and caused additional damage to turbines 1 and 3, with slight damage to turbines 4, 5, 8, and 10.[26] Turbine 6, which was in scheduled repair at the time of the accident, received only minor damage and was the only one of the station's 10 turbines that did not receive electrical damage due to shorting of the associated transformers.[27] Water immediately flooded the engine and turbine rooms and caused a transformer explosion.[28] Transformers 1 and 2 were destroyed, while transformers 3, 4, and 5 were left in satisfactory condition. Other damage was also severe as the machinery hall was destroyed, including the roof, ceilings, and floor.[citation needed]
