The San Onofre Nuclear Generating System planned to test its alert siren system on Wednesday.
Officials say poor welding work and pin-hole leaks are keeping one of the San Onofre's nuclear reactors from returning to service. That's not the only safety issue the plant has recently faced.
Plant officials told our media partner The North County Times that the reactor's leak problems have now been repaired.
Unfortunately, they have delayed the reactor from returning to service by about three weeks.
And in an unrelated incident, a report surfaced this week that plant officials waited more than two weeks before reporting a minor safety issue to federal regulators.
Plant officials say they didn't realize the issue, involving a shutdown of a mechanism that cools some of the plant's fuel, needed to be reported.
