I've done a lot of traveling since receiving a CI in 2005. I've never had a problem getting through security. Wear your processor. Same for hearing aids. Keep your extra equipment in a small bag you can carry. Open the bag and show them what it is. They should allow it to go through the check in without any Xrays. You should have a card from your implant center that states that you have a CI. I've never been asked for that, but carry it with me just in case. In any case, it's wise to be upfront about having a CI before you go through security so they know your situation. Don't wait until they detect something they weren't expecting. Happy Travels!
