Impact of Operating Experience with the First Unit at Tihange on the Design of Two Further Units

摘要

The problems of radiation protection for persons entering and working in a nuclear power station have to be dealt with at every stage in the construction and operation of that power station. It is a problem for the designers and manufacturers of nuclear plant, particularly the manufacturer of the nuclear steam supply system. It is also an important problem for the architect, as he is largely responsible for the layout of the plant. Finally, it is a crucial problem for the operator since he has to cope with all the difficulties caused by inadequacies in the design of the radiation protection system of the power station when it is handed over to him. The operator will of course be aware of all the defects in his installation, particularly those concerning radiation protection, but he will only be able to deal with them in a limited way. This paper discusses the lessons learned from the first unit at Tihange and then describes various modifications which have been made as a result and which will mean improvements in two additional units currently under construction.
