NNEGC Energoatom operates all Ukrainian nuclear power plants (NPP). The “Separated Entity Scientific and Technical Centre” (SE-STC) is a structural subdivision of the NNEGC “Energoatom” established at same level as the NPPs.
The purpose of SE-STC is to provide technical expertise to the Energoatom’s nuclear power plants in different areas such as operation, maintenance, safety and reliability assessment, reactor physics, and radiochemistry. SE-STC also helps coordinating scientific work and technical support in the field of nuclear engineering, providing an interaction with other enterprises providing scientific, technical and engineering services for NPP in Ukraine to avoid duplication of works.
In addition to the abovementioned activities, SE-STC had also intended to establish an internal competence in calculations of core parameters for core load design of VVER 1000/320 reactors by using the computational codes applied in EU to reduce its dependence on Russian institutes. Two specific supply contracts were therefore established within the U2.01/04 project on “Scientific, technical and organisational support to the SE-STC” to provide the software and user’s license for specialized reactor core calculation codes Helios and DYN3D as well as necessary training to the SE-STC personnel. An appropriately configured computer server to run these specialized codes has been delivered through another equipment supply contract (lot) of U2.01/04S.


The objective of the 133022 supply contract was to help to the SE-STC to develop internal competencies in 3D modelling of VVER 1000/320 reactor core by supplying the computational code DYN3D including 3D neutron-kinetic model for dynamic and depletion-up calculations in light-water reactor (LWR) cores (core response to reactivity changes, reactor poisoning) and a thermo-hydraulic model of LWR core (modelled by parallel coolant channels). A part of the DYN3D software package was to be also a link to the Helios code (software for cross section library generation with the necessary interface).The supply was supposed to cover full license (with 1 year warranty period, including code maintenance and min 100 h of user support), software installation, and 1-week training of the SE-STC staff.


This contract was a direct agreement one made with the Forschungszentrum Dresdner Rosendorf (FZD. The contract was signed on 19.12.2007 and the implementation period was 16 months. The value of the contract (fully covered by EC funds) was 82 470 €. The DYN3D code including the link to the Helios macroscopic cross section libraries was delivered and installed at the Energoatom’s SE STC. The user support was provided. The Final Acceptance Certificate was signed at the end of the one-year warranty period on 9 April 2010. The contract was closed on 7 March 2012.
