BUCHANAN — A security lieutenant at New York’s Indian Point nuclear power complex has filed a lawsuit claiming the plant is unsecure, and that staffers regularly watch DVDs, play video games and sleep on the job.

The $1.5 billion lawsuit was filed Tuesday in state Supreme Court by Clifton Travis Jr. It names as defendants the plant owner, Entergy, and three managers. Travis still works at the plant, but says he’s been marginalized over his security criticism.

The suit also claims the plant, about 50 miles north of New York City, also routinely fails anti-terrorism drills.

The company says it hadn’t yet been served with the suit.

Spokesman Jim Steets says Entergy invested more than $100 million in the last 10 years on security and the federal government has deemed it secure.
