Computer codes application

Experience in using computer programs, verification and validation

Specialized computer programs are the main tool in performing the main tasks of ENPRO CONSULT. The company has acquired the necessary computer systems and codes. Highly professional IT specialists maintain the operating systems (MS Windows and Linux) and maintain the security of information resources in the local network.

If necessary, Version Control System (VCS) is widely used.

Extensive experience has been accumulated in the field of modeling, verification and validation of models, including documentation and archiving.

Based on ATHLET and the ATLAS visualization system, an analysis simulator for units 5 and 6 at Kozloduy NPP has been developed. It is a powerful tool for verification of emergency instructions. The simulator includes models of the VVER-1000 control systems and provides the opportunity for interactive control.

Below is a brief description of the computer programs used for safety design and analysis.

The input data packages for the various computer codes are constantly updated, during which strict verification is performed. Comparative analyses with different programs are often carried out in order to verify the models. Validation by comparison with measured data at the plant and records of operational events is also performed when necessary.
