24 February 2009 – Mitsubishi Heavy Industries delivered a pair of replacement steam generators for the second unit of Southern California Edison’s San Onofre Nuclear Generating Station (SONGS).
The generators will replace existing units during the plant’s next refueling and maintenance outage, scheduled for the fall. MHI will ship two more generators to SCE later this year for installation in SONGS Unit 3 in the autumn of 2010.
The steam generators delivered each measure about seven meters in external diameter and weigh 580 tons.
MHI received the order from SCE in September 2004 after winning an international bidding competition. The contract did not include installation work.
There are two units at the SONGS plant, the 1,070 MWe Unit 2 and 1,080 MWe Unit 3, which entered service in 1983 and 1984, respectively. Replacement of the steam generators in use will enable the plant to operate until 2022.
