In order to provide a completely leak-proof circuit for heavy water used as coolant in a reactor and passing as heating fluid through a heat exchanger, the heat exchanger comprises a multitude of heat exchange elements, each formed by simultaneously rolling two metal sheets together (roll-bonding) except at the areas which are to define the fluid circulating path; these areas are provided with a layer which prevents welding. The coolant channels are formed by expanding the sheets hydraulically at these areas. Each element contains parallel channels connecting a pair of headers. The elements are rectangular and are arranged with their headers and their inlet and outlet tubes in contact, the tubes being on the same side of the element. The heavy water flows through these elements, which are connected in parallel, while ordinary water circulates outside between these elements. In each element the cooling channels are grouped and connected in such a way that channels of one group are in parallel and successive groups are in series. (NPO)
