The first of all the Report summarizes data which was received in Soviet Union (later Russia) and Czech Republic as the main countries which had produced this type of RPV. The book summarizes historical basis for the choice of materials, main principles of RPV design and manufacturing as well as results from Qualification Test Programmes, statistical evaluation of test results from individual type of semi-products/welds and final vessels. Information on defects/repair of semi-products/vessels was included together with available information about vessels behaviour during operation. Finally, comparison of existing data with Code/standards requirements will be given.|
