SCE wants to run SONGS Unit 2 at reduced power

The U.S. Nuclear Regulatory Commission (NRC) received a proposed action plan from Southern California Edison (SCE) that includes operating Unit 2 at the 2,200 MW San Onofre Nuclear Generating Station (SONGS) at reduced power for five months.

SCE must first receive approval from the NRC to operate Unit 2 at 70 percent power for the five-month period, after which it would shut down for an inspection to examine the steam generators again. NRC said it expects to spend several months reviewing documents submitted by SCE and performing a thorough and independent assessment prior to making a decision about restart.

Unit 3 was shut down Jan. 31 after a leak in the steam generator led to the discovery of unexpected wear on tubes inside the generator. Unit 2 was offline at the time for planned maintenance, and inspection of that unit revealed the same tube wear. In June, NRC said faulty computer modeling inadequately predicted conditions in the generators and manufacturing issues contributed to excessive wear of the components.

Unit 3 remains shut down indefinitely. "The reality is that Unit 3 reactor at San Onofre will not be operating for some time," SCE said on Twitter.
