CDI Corp.’s Aerospace and Industrial Equipment (AIE) business has entered into a long-term service agreement with Lawrence Livermore National Security LLC in support of the Lawrence Livermore National Laboratory (LLNL) National Ignition Facility in Livermore, Calif., extending the company’s master services relationship begun in 2008. CDI-AIE will provide LLNL’s Ignition and Photon Science Directorate with engineering services across a wide variety of disciplines. The National Ignition Facility, with the world's largest and most energetic laser, is a critical tool for ensuring national security, performing experiments that may lead to nuclear fusion in a laboratory setting and advancing basic science. These efforts allow scientists to help ensure the country's safety without nuclear weapon testing, define energy for the future and gain a better understanding of the universe. The four-year contract also allows CDI to provide engineering support to the entire LLNL complex including the defense technologies, engineering technologies, national security engineering and technology resources engineering divisions. CDI provides engineering support to energy, chemical, infrastructure, aerospace, industrial and defense clients. The LLNL is a federal research facility for national security technology.
