I’ve written dozens of times in a decade about my skepticism regarding the safety of Indian Point and with every passing month, little happens to alleviate my worry.

Time was we couldn’t depend on Con Edison to be up front and timely in admitting problems at the plant. There have been engineering and maintenance issues, leaks and unexpected shutdowns.

But over and over, there have been problems with the warning sirens that are supposed to alert residents within the 1-mile zone around the plant in the event of a need to evacuate.

Of course, when a problem reached that threshold is a matter of opinion. I’d like to be alerted far more often than anyone at Entergy or the NRC seems to think necessary.

For years, we saw siren tests in which large numbers of sirens failed to sound, which kind of undermines anyone’s standards for when they should blast us awake. There were times tests couldn’t be conducted because thunderstorms disrupted phone lines. At least once the system that allowed nearby counties to activate the sirens dropped out of service with no one noticing until Rockland officials, running a routine test, discovered the problem.

Finally, the siren system was replaced and went into service after numerous delays. It’s still really undergoing tests, with the original system used as a backup, waiting to be dismantled.

Just Wednesday, they fired up the sirens again and sure enough, 18 of the sirens failed in one way or another.

Although I have faith in the emergency officials who oversee Indian Point’s evacuation plan, I’ve never felt the least bit sure it could would in a real emergency.

Knowing that we still can’t depend on every siren to sound, and loud enough to be heard,  does little to make me feel safe.
