A report released Friday by the Nuclear Regulatory Commission provides the most detailed picture to date of how a flawed system of new steam generators at the San Onofre nuclear power plant was designed.

Time staff writer Abby Sewell will join us at 9 a.m. to discuss the report on the root causes of problems at the plant. It shows that officials considered making design changes to the steam generators before they were installed but rejected some fixes in part because they would require further regulatory approvals.

Some of the generators began to malfunction a year after they were installed, and the plant has been shuttered for 13 months. The closure has cost San Onofre’s owners, Southern California Edison and San Diego Gas & Electric, more than $470 million. Ratepayers across the region are shouldering some of the plant’s costs and could be on the hook for hefty future repair bills.
