Fusion of eastern and western technology in vver 1000 NPP upgrade

摘要

An extensive modernisation program upgrading two units of VVER 1000 type of the Czech nuclear power platn (NPP0 Temelin to meet the latest international standards is presented. The program is based primarily on combination of eastern and western technology and it has been implemetned during plant construction. The NPP Temelin was originally designed acording to the standards of the former Soviet Union. After a series of reviews in the 1990s, a decision was made by the Temelin management to upgrade the design of the plant, including the supply of fuel and instrumetnation and control system by a western company. The adoption of western technology and practices has helped to solve a large number of IAEA safety issues related to design and operation of VVER 1000 NPP. Details on the current Temelin design and other related safety matters are presented.
