Simulator modification completed at Kozloduy

A turnover meeting on November 16 marked completion of a collaborative project to modify the full-scope simulator for Kozloduy Unit 6. The modifications, begun in July 1999 and completed in late September 2000, involved upgrading the simulator's hardware to reflect the actual configuration of the plant as well as software to support the new hardware and system changes. The U.S. contractor for the project, GSE Power Systems, Inc., had worked directly with plant management to design the original simulator for Unit 6. However, even before the simulator was completed, the physical structure of Unit 6 underwent substantial changes, necessitating modifications to the simulator.

On September 27, GSE, its Bulgarian subcontractor, Risk Engineering, Ltd., and technical specialists from Kozloduy NPP approved the U.S.-supported software modifications and documentation as well as hardware modifications subsidized by the plant. The modified simulator was declared ready for training and has entered the one-year warrantee period. U.S. team members from Pacific Northwest National Laboratory participated with the contractor and plant representatives in the mid-November turnover at Kozloduy NPP.
