pool type sodium cooled fast reactor

kg/s The device of the invention is stacked by box-typed shielding slabs, wherein, the box body of the box-type shielding slabs is welded by a carbon steel plate and serpentine concrete is poured in the box body. Flow through the air themperature air heat exchanger intake air heat exchanger outlet of air heat exchanger The Sodium-cooled Fast Reactor (SFR) uses low-pressure liquid sodium as the reactor coolant, allowing high power density with low coolant volume fraction. The sodium-cooled, pool-type fast reactor was constructed with Russian assistance at the China Institute of Atomic Energy (CIEA), near Beijing, which undertakes fundamental research on nuclear science and technology. The design concepts of a reactor vessel (RV) and its internal structures have been investigated whether they could withstand severe seismic conditions in Japan and thermal loads. pool type sodium fast reactor air Prior art date 2007-12-11 Application number CNA2007101950213A Other languages Chinese (zh) Inventor 徐銤 刘莲萍 杨福昌 叶原武 余华金 刘嘉一 唐龙 许义军 杨志民 张东辉 Original Assignee 中国原子能科学研究院 Priority date (The priority date is an assumption and is not a … One loop sodium temperature independence heat exchanger entrance independence heat exchanger outlet The PRISM is inherently safe due to its neg-ative power reactivity feedback, large in-vessel coolant inventory,passiveheatremovalsystems,below-gradesit- ?0.525 Sodium-cooled reactors could be categorized into two types: loop and pool types (Figure 5.3, Figure 5.4). [4] The heap nominal condition kg/s In India, a pool type liquid metal cooled Fast Breeder Reactor [PFBR] is under construction at Kalpakkam. ? A few significant structural dynamics problems such as pump induced as well as flow induced vibration and seismic excitation is very critical in a fast breeder reactor. ?1.66 This will have an output of 1500 MW thermal power and 600 MW electric power. The authors have also conducted a transient analysis of loss of flow type anticipated transients without scram events to evaluate the feasibility of a self-actuated shutdown system. ??? This research proposes the use of the tube- in- duct or vented fuel design rather than the conventional pin cell. Accident afterheat exhausting system provided by the present invention, it has two characteristics, first independence.Independently heat-transfer system is overlapped by this system, and it has oneself a loop and secondary circuit (intermediate loop), can not rely on main heat-transfer system just the residue heat release of reactor core can be derived.It two is non-dynamic roles.One loop of this system and secondary circuit (intermediate loop) and the air that flows through air heat exchanger all adopt the mode of Natural Circulation to move, and in the trunk line of system, do not establish any valve, it is active having only the import and export air door of air heat exchanger, thereby has guaranteed the non-dynamic role of native system to greatest extent.In a word, native system effectively overcome the technology of enjoying defective, when accident conditions, can be effectively the residue heat release of reactor core be discharged. It provides biological and thermal shielding in the top axial direction of the reactor. When native system was in standby function, import air door 4 was all opened, and outlet air door 2 is closed, but leaves 10% gap.Close the valve of the argon system of the sodium fill-drain syctem that connects native system and secondary circuit, accident afterheat exhausting system.The sodium of native system intermediate loop enters the expansion drum of air heat exchanger 3 from independent heat exchanger 5 along pipeline under the Natural Circulation effect, and be diverted to the heat exchanger tube tube bank by the latter, and with the heat transferred air, sodium is got back to independent heat exchanger along pipeline.Under the draft effect of pulling out wind and smoke chimney 1, the import air door 4 of air through opening enters in the air heat exchanger 3, and enters atmosphere through exporting air door 2 and pulling out wind and smoke chimney 1.One loop sodium enters the entry grates of independent heat exchanger 5 under the Natural Circulation effect, by shell side, flow to the bottom in reactor " heat " chamber.
