Abstract (en)
[origin: EP0110363A2] To reduce costs both through material and labour savings of a nuclear plantheat exchanger, the latter comprises two quadrangular cross-section headers (1, 2) coupled by a yoke-like tube nest (3) which is cold pre-deformed in such a way as to minimize the primary stresses of thermal origin developed during the operation of the exchanger.
