L3Harris Technologies to Upgrade Cernavodă Utility Operator Training Simulator


  • L3Harris to upgrade Romanian simulator hardware and software
  • Extends long-term relationship between L3Harris and CNE Cernavodă
  • Upgraded simulator to be in service in third quarter of 2021

MONTREAL December 3, 2019 – L3Harris Technologies (NYSE:LHX), has been selected by Societatea Nationala Nuclearelectrica S.A. (SNN), a Romanian state-owned utilities company, to upgrade the Cernavodă utility operator training simulator.

L3Harris will modernize the existing simulator’s aging hardware and improve its software performance and maintainability. The upgraded CANDU* operator training simulator is expected to be in service in the third quarter of 2021.

“Extending the service life of the full scope simulator is an important element for continued initial, authorization and reauthorization training, as SNN prepares for the refurbishment of the Unit 1 reactor,” said Dan Bigu, Director of CNE Cernavodă. “We look forward to working closely with L3Harris’ high-performance team to upgrade the simulator.”

In the first stage of the project, L3Harris will upgrade the simulation computers and operating systems, while re-platforming the existing plant models to L3Harris’ state-of-the-art Orchid® simulation environment. The primary heat transport, boilers and containment models will be redeveloped in Orchid Modeling Environment. Additionally, the simulator will be enhanced to include severe accident simulation capabilities using a version of the Modular Accident Analysis Program, known as MAAP5-CANDU**, augmented with 2D and 3D animated, interactive visualizations of the reactor vessel and containment building to provide trainees further insight into the behavior of the plant during unlikely severe accidents.

During the second stage, the simulator’s AC and DC power supplies will be replaced, and the legacy Datapath SC input/output (I/O) system will be replaced with a new compact I/O system driven by L3Harris’ Orchid Input Output software.

“This agreement extends our nearly 30-year partnership with CNE Cernavodă and demonstrates their confidence in us to tackle extremely challenging projects,” said Michael Chatlani, Vice President, Business Development, Power Systems and Simulation, L3Harris.

L3Harris has over 45 years of experience in delivering high-fidelity power plant simulation to leading utilities worldwide. In addition, the company has more than four decades of expertise in supplying plant computer systems for heavy water reactors. To learn more, visit
