1. SCE selected steam generators (SGs) from MHI as low bidder
2. SCE told MHI to change the SG design from original SGs
3. SCE told NRC the new SG design is like for like
4. MHI designed and built lousy SGs
5. SCE contracted to remove old SGs and to install these lousy SGs into the plant
6. The lousy SGs started wearing out after only one year
7. One of the SGs developed a leak and the had to shutdown
8. SCE and worldwide consults came up with only two solutions - replace these SGs or operate the plant at reduced power with the hope that the wearing will stop.
9. SCE wanted to go with reduced power operation for one reactor but NRC regulations would not allow this experiment without a formal licensing amendment.
10. SCE decided that the formal license amendment process was too long and made the business decision for permanent shutdown of the reactors.
Root cause of problem is not politics or NRC. Root cause is SCE wanted more steam generator tubes and deviated from the original CE design. SCE should have stayed with the original CE design which lasted more than 30 years. SCE only had another 20 years to operate the reactors.
