A Kansas nuclear power plant is going through major changes to protect itself from any kind of attack.

At the Wolf Creek Nuclear Power Plant near Burlington, keeping intruders out has always been a top priority.

Since Sept. 11, Wolf Creek has spent more than $1 million on security upgrades. It's also increased security operating costs by $1 million a year.

Changes in Wolf Creek's security include a perimeter that's further away from the power plant since Sept. 11.

The security gate is now just over a mile away, and tire shredders are in place if someone unauthorized tries to drive through.

Security has always been a top priority at the Wolf Creek Nuclear Power Plant. But since the Sept. 11 terrorist attacks things like concrete barriers have also been added to increase that security.

The barrier to prevent someone with a car bomb from getting through seem to be everywhere.

But what everyone wants to know is what would happen if a large plane crashed into the plant?

"It would withstand a very large aircraft impact without any release of radioactive material. Without any harm to the public," said Wolf Creek CEO Otto Maynard.

The Nuclear Regulatory Commission requires plant officers to be prepared against certain threats.

"We train our officers constantly through drills and scenarios that insure that they can safely protect the plant from that threat," said Security Trainer Lauren Cox.

Wolf Creek has more security layers and barriers than a lot of airports. Some are visible, some are not.

But when you're dealing with nuclear power, something that's scary to some people in peaceful times, perhaps there's never too much security.
