Patent FR-2199167-A1 (FR)
Title: Pressurised water reactor plant - with integral primary circuit pumps and steam raising units
IPC: G21C13/00
Filed: 1973-09-07
Abstract: In the plant, the primary circuit components of steam raising units and circulating pumps are an integral configuration effecting a reduction in overall containment and plant component dimensions with consequent cost economies. The steam raising units are housed adjacent but external to the reactor pressure vessel containment with the motor driven circulating pumps mounted either vertically or horizontally beneath and partially encapsulated by the steam raising unit containment. The primary circuit pipework between the reactor and steam raisers is pref. short and further space economy is effected by using concentric pipes with the inner acting as flow to the steam raiser and the annulus between the two pipes as return flow to the reactor.

Title: Dialyser for ion exchange - useful partic as artificial kidney and in industrial applications
IPC: B01D63/00
Filed: 1974-03-05
Abstract: An appts. for ion exchange by dialysis is made from discs which have spiral grooves on their faces and which are built up to enclose between them membranes in which a liq. to be treated, e.g. blood, circulates. The dialysate circulates in the grooves and the two streams flow in opposite directions to one another. The assembly is contained in a casing. There are holes for feeding and discharging dialysate and liq. to be treated, in the casing, in the discs at the beginnings and ends of the spirals and in the membranes. The depth of the grooves is such as to allow the liq. to circulate easily. The width between them is such as to form a continuous support for the flexible membrane which is held between them. The grooves can admit an electrical conductor or can allow the circulation of a suitable gas. The membranes and discs can be stacked in multiple units. The dimensions, assembly and materials of construction are variable according to the required use. The membrane may be replaced by a continuous tube in which the liq. to be treated flows. Used in medico-surgical applications and in indl. applicns. such as sugar sepn., purificn. of dextrin and tannin, prepn. of alkaloids etc. Partic. as an artificial kidney for treatment of patients with renal affections. The appts. is more efficient than existing appts. because of the greater fluid path length and because of the continuous flow which eliminates risks of eddying and high pressure drop.

Patent FR-2300400-A1 (FR)
Title: Nuclear reactor emergency coolant system - with passive pressure-responsive coolant reservoir arrangement
IPC: G21C9/00
Filed: 1975-02-10
Abstract: Nuclear plant includes a reactor and steam generator sealed in a containment structure and connected by a flow line at a normally constant pressure. The containment structure also encloses a coolant liquid reservoir at a pressure lower than the coolant flow line, and communicating both with the reactor assembly with the steam generator. In a loss of coolant accident, a predetermined pressure drop in the coolant flow line causes liquid to flow from the reservoir to the reactor assembly, and a further predetermined pressure drop between the reservoir and the steam generator results in a flow of steam which pumps liquid from the reservoir to fill the reactor assembly. The system is applicable to pressurised or boiling water reactors using light or heavy water as coolant or moderator. Complete containment is ensured, and emergency operation is wholly passive.
