Intergraph Information Systems Technology Supports Nuclear Plants’ Decommissioning

NEOLANT chose Intergraph® technologies for creating the decommissioning database of the power generation units at Smolenskaya, Bilibino, and Kolskaya Nuclear Power Plants (NPP).

The Challenge

NEOLANT was the selected engineering company for the decommissioning of power generation units at Smolenskaya, Bilibino, and Kolskaya Nuclear Power Plants (NPP). The contractor needed to create an effective information support system to support the whole capital life cycle management of the project, maintaining data integrity and accuracy of engineering information. The information system was built based on SmartPlant® Enterprise and named “decommissioning database.”

The nucleus of the database is based on the NPP information model, a standard NPP model which contains current design and engineering data needed in the decommissioning process. The information model itself is an engineering data management system. As the project goes, different IT tools join the system: applications to gather data, applications for engineering evaluation and simulation modeling, and applications for business analysis are all involved in decommissioning.

NEOLANT chose Intergraph® technologies for creating the decommissioning database at Bilibino, Kolskaya, and Smolenskaya NPPs because:

  • Solutions are easy to use by staff involved in the decommissioning project
  • All actions performed within the project are recorded for reporting and reuse
  • Technical support is offered by Intergraph
  • NEOLANT has broad experience in the use of Intergraph solutions

The decommissioning database at Smolenskaya, Bilibino, and Kolskaya NPPs was created using SmartPlant Electrical, SmartPlant Foundation, SmartPlant P&ID, and Intergraph Smart™ 3D. SmartPlant P&ID was used for two-dimensional technology schemes development, which were used later for putting together 3D models in Smart 3D.

Recovering thousands of drawings and as-built documentation from the plants posed a challenge to engineers and other specialists from NEOLANT and Intergraph. The lack of an application among SmartPlant Enterprise solutions for creating a general plot plan was challenging, because other 2D and 3D CAD tools had to be brought in. An interface with SmartPlant Foundation was created.

The Solution

It took six months to create and launch the Intergraph decommissioning database system. Each NPP’s database is customized in terms of data model extension. For instance, at Kolskaya NPP, 20,931 project-related sketches were scanned and uploaded to the system. The decommissioning database was built upon a single information model which includes 14,532 objects.

Today, the decommissioning databases at the three NPPs work effectively and play a key role in:

  • Gathering and keeping data linked to all information systems at NPPs
  • Exchanging data among all information systems at NPPs
  • Providing all necessary data for mandatory decommissioning reports, including reports on the unit's technical condition
  • Providing radioactive waste and spent nuclear fuel data integration
  • Visualizing the structure and patterns of all NPP objects (as well as nuclear unit parts)
