Mark Holecek has been chosen to manage the Kansas City site office for the National Nuclear Security Administration. Holecek, who has been deputy manager for the siteâ¿¿s Office of Stockpile Management, has been responsible for day-to-day work to meet the goals of the Kansas City Plantâ¿¿s contract with Honeywell Corp., which recently was extended for five years while a new, $673 million plant is built. He played a key part in the project to move the plant to a new, smaller facility â¿¿ dubbed Kansas City Responsive Infrastructure, Manufacturing and Sourcing â¿¿ that will cost $100 million less a year to run. In his new role, Holecek will oversee the Kansas City Plant contract, including operations in Kansas City, New Mexico and Arkansas. â¿¿Markâ¿¿s commitment to NNSAâ¿¿s mission will ensure that the Kansas City Plant will continue to provide high-tech production services across the nuclear security enterprise,â¿ Don Cook, deputy administrator for defense programs, said in a release. Holecek has been at the Kansas City office since 1994, when he began as a quality engineer. He has held several other roles, such as weapons program engineer, quality engineering team lead and assistant site manager. The NNSA, a U.S. Department of Energy agency, was set up by Congress in 2000 to improve national security through nuclear science in military applications. The Kansas City Plant in the Bannister Road Federal Complex is responsible for significant maintenance and upgrades to much of the U.S. missile arsenal, providing up-to-date avionics and other non-nuclear components for nuclear weapons. The plant does not receive or handle nuclear components. The Kansas City Plant is one component of a multistate complex of plants that manufacture or service nuclear weapons. Honeywell has operated the plant through a contract awarded in 2000 and valued at a total of $4.1 billion.
