SONGS-2 and 3 are commercial Combustion Engineering (CE or C-E) PWR power reactors. Each reactor had 2 steam generators, and considered 2-loop reactors. However, because each SG has 2 cold legs, they can sometimes be referred to as 4-loop. Both had a generating capacity of around 1100 MWe each and are both owned by SCE (Southern California Edison) and three other partners. Along with Waterford 3, SONGS 2 and 3 are referred to as "Group 5" CE Plants. Both SONGS 2 & 3 reactors operated from 1983/1984 to 2012 after problems with recently installed Steam Generators.
On June 12, 2013 SCE formally notified the Nuclear Regulatory Commission (NRC) that it had permanently ceased operation of both units on June 7, 2013. Both units recently had new Steam Generators and new RV Closure Heads installed, but S/G tube sheet issues triggered evaluating the economics of keeping both units producing power. Currently SCE is planning to remove both reactors over the next few years with intent to complete segmentation of both reactors in 2019.
The RFP that includes reactor work is due the first week of January, 2016 (was October 2015). Award expected middle 2016. The teams and major groups bidding this work are:
