Bulgarian Specialists Satisfied with Quality of Russian NPP Equipment
OREANDA-NEWS. March 19, 2012. On the 12th – 15th of March 2012 a Bulgarian delegation visited the Machine Engineering Plant ZiO-Podolsk, part of Atomenergomash Group of Companies.
The delegation which held a three–day visit to the Russian company, included the head of annual outage planning and preparation group of Kozloduy NPP Emil Pisarev, chief expert of mechanical equipment of the turbine island Rumen Mirchev, and head of division and authorized representative of quality division at ATP-ATOMPLOPROEKT Evgeni Peshev.
The Bulgarian specialists were given a package of regulatory, design, technological and reporting documentation written basing on quality control results obtained at all stages of manufacturing of high pressure heaters (HPH) supplied to Kozloduy NPP. Specifically, the stages were from quality control of input materials through testing of ready-made HPHs. The specialists from Bulgaria had also an opportunity to familiarize with results of additional (in excess of established requirements) mechanical tests, chemistry studies and metallographic studies of materials used for HPHs. The tests and studies were carried out in laboratories of ZiO-Podolsk which are qualified by independent agencies for carrying out all kinds of inspections established by regulations. Also, some tests were carried out in several independent laboratories. The test and inspection results were recorded in reports which will be stored during the entire service life of the equipment.
“We are fully satisfied with results of the data analysis which confirm conformance of the chemical composition and other characteristics of the base metal of tube plates, barrels, bottom pieces and other parts of HPHs with the established regulatory and engineering requirements. We don’t have any issues to raise as to the operation of HPH made by ZiO-Podolsk,” Emil Pisarev said.
Basing on the work results a record was signed where the Russian and Bulgarian sides expressed their wish to continue technical reviews during scheduled outages of Units 5 and 6 of Kozloduy NPP in April and September 2012. During the scheduled outages an additional study of chemical composition of the HPH base metal will be carried out in presence of the Russian manufacturer’s representative.
