NEOLANT Releases Digital Decommissioning for Decommissioning Nuclear Facilities Efficiently

30.07.2018

The NEOLANT Group of companies today released its newest software and hardware package, Digital Decommissioning for comprehensive engineering and radiation survey, developing decommissioning concepts, decommissioning designs, personnel training for decommissioning.

Conditions of radioactive contamination posing threats to the facility personnel and population of adjacent territories characterize procedures of decommissioning of nuclear power and nuclear fuel cycle facilities. It prevents the direct participation of the staff in certain operations and its presence in some areas of facility under decommissioning. Significant amount of radioactive waste accumulated during the period of its operation and massively generated during the decommissioning should be also considered.

The need to mitigate emerging threats resulted in the fact that the stage of detailed design of nuclear facility decommissioning is mandatory, and the decommissioning is a rather expensive phase of the facility life cycle.

"Application of Digital Decommissioning package ensures achievement of a fundamentally new quality level of design for nuclear facility decommissioning supported by multi-dimensional dynamic simulation of a radiation-dangerous facility and technological processes ensuring the dismantling, elimination of radioactive contamination, and management of the radioactive waste generated at an improved level of safety, reliability, and economic efficiency.
 It became possible through the use of building information modeling, virtual reality, laser scanning, and spherical photography, which provide creation of a digital as-built engineering and radiation model of a facility under decommissioning," says Vladislav Tikhonovsky, First Deputy Director General at NEOLANT GC.

Advantages of the Digital Decommissioning Package

  • Highly precise estimation of radwaste amount classified by specific activity, morphology, and reprocessing methods
  • Variants calculation of radiation fields dynamics considering sequence of the equipment and utility systems disassembling
  • Justified calculation of production and economic indicators of a decommissioning project: resources, time, dose rates, design and estimate indicators
  • Maximizes the safety of decommissioning activities
  • Combines personnel training with decommissioning project development

Customer Success Story

Digital Decommissioning package is used in the first nuclear power plant decommissioning project in Europe with digital support the back-end stage of nuclear power plant units – Project 44: Development of an equipment dismantling project in the controlled access areas of Kozloduy nuclear power plant, units 1-4.

The project is implemented by the Russian-German consortium comprising of GC NEOLANT, JSC NIKIMT Atomstroy, NUKEM Technologies GmbH, and EWN GmbH.
