    • PURPOSE:To eliminate a heat exchanger and a guide vessel for primary main circulating pump by a method wherein a pump is equipped in the space of the heat exchanger, in which an electric heater is not equipped, and an outside shell is utilized as a secondary sodium boundary while a guide pipe is provided in the outlet pipeline of primary system. CONSTITUTION:Primary cooling sodium flows through an inlet nozzle 13a, flows down the outside of a heat insulating wall 29, flows into an electric heater tube 12 through an inlet window 14, descends the outside, flows into an intermediate prenum 30 and pump hydraulic section 31 and is flowed into a primary system pipeline 4 through a delivery pipe 26 by the boosting of an impeller. Secondary system sodium from the inlet nozzle 17 descends between an outer cylinder 8 and an inner cylinder 9, ascends from a lower prenum 19 through the electric heater tube 12 and flows out of an outlet nozzle 21. Sodium boundary, above the outer cylinder 8 of the heat exchanger, is higher than a level necessary for securing cooling material and a part lower than said boundary is enclosed by secondary cooling material having a high pressure, therefore, the primary cooling material will never leak to the outside even if the outer cylinder 8 is broken. The guide pipe 28 is provided at a part lower than the system level of primary sodium of the pipeline connected to the outlet nozzle 16 of the primary system.

    • PURPOSE:To discriminate broken heat transfer tube easily by a method wherein a suspension cylinder is provided at the outer side surface with a skirt so as to cover the inlet window of primary series sodium and with a penetrating hole for gas leak near an upper tube plate in order to monitor only the upper surface of the tube plate by a television camera. CONSTITUTION:In case leakage is caused in the heat transfer tube 14, the secondary series sodium in the intermediate heat exchanger 4 is drained and the pressure of secondary series cover gas 26 is increased, then, the gas leaks from the leaking part 27 of the leaking heat transfer tube into the primary series. A liquid level surface 11a descends to the position of the penetrating hole 25 for gas leak, which is provided on the skirt 21, and the primary series cover gas 28 leaks from the penetrating hole 25 to the outside of the intermediate heat exchanger 4. The level surface 11a is kept near the upper surface of the upper tube plate 15 and thereby permitting to detect the leaking heat transfer tube by the television camera.
