Refueling involves taking the spent core out of the reactor and putting in a new core with new nuclear fuel. Because it is so radioactive, removing a core with spent nuclear fuel from a reactor requires elaborate radiological handling precautions. He said that the two main causes of the delay were unplanned growth work, although he did not specify in which areas, as well as labor inefficiencies. While serving as an aircraft carrier for the Advanced Deployed Naval Force (FDNF), George Washington would perform a couple of shorter deployments each year and then move to short annual maintenance availability, compared to the rest of the aircraft carrier fleet that goes through a three-year cycle of maintenance availability important.
training and a deployment of six or seven months. That FDNF aircraft carrier, then, receives more frequent routine maintenance on the hull, mechanical and electrical systems, but the shipyard in Japan cannot do all the work on the nuclear propulsion system that a shipyard in the united states can do. The Navy aircraft carrier undergoing mid-life refueling is now delayed by more than a year, due to new jobs that emerged during the repair and pandemic-related labor challenges. The aircraft carrier USS George Washington (CVN-7) is more than halfway through its refueling and complex overhaul and is scheduled to leave the Newport News Shipbuilding dry dock next month to begin the next phase of a four-year review.
CAPITOL HILL — Lawmakers today told industry representatives that, if it wasn't already clear in their hearings with Pentagon and Navy leaders this week, they had no intention of allowing the Department of Defense to dispose of an aircraft carrier instead of refueling it. The USS George Washington, a Nimitz-class aircraft carrier launched in 1990, is in port for mid-life refueling. The aircraft carrier USS George Washington (CVN 7) is towed by tugs to its new home port in Newport News, Virginia. While the Nimitz-class nuclear-powered aircraft carrier is expected to serve for half a century, it requires a mid-life refueling to exchange worn reactor fuel rods.
Refueling and complex overhaul, known as RCOH, is performed only once for each nuclear aircraft carrier, refueling the ship's nuclear reactors and overhauling almost every other system. This was the first RCOH for the Nimitz class and only the fourth achieved on a nuclear aircraft carrier. The work, which would replace the nuclear fuel that powers the aircraft carrier's reactors, has been delayed by more than a year.

The aircraft carrier USS George Washington (CVN-7) began a 48-month review of the complex and refueling at Newport News Shipbuilding earlier this month after serving for seven years as aircraft carriers deployed forward in Japan, creating a somewhat unique work package for the Navy's sixth RCOH. Stennis (CVN-7) is now at Newport News Shipbuilding for its middle-aged nuclear refueling and overhaul, the Navy announced Thursday.
