pool type sodium cooled fast reactor

?50 ??? ?7 The accidental afterheat discharge system provided by the invention has independence and nonmotility. 3. the accident afterheat exhausting system of pool type natrium cold fast reactor according to claim 2, it is characterized in that: the adapter of described independent heat exchanger (5) is provided with protective sleeve. Pool type sodium cooled fast reactors pose several design challenges and among them, certain thermal hydraulics and structural mechanics issues are special. ?MW ℃ The development of this concept will broaden not only options for reactor types in Japan but also the range and depth of international cooperation. Pool type sodium cooled fast reactors pose several design challenges and among them, certain thermal hydraulics and structural mechanics issues are special. The European Sodium-cooled Fast Reactor (ESFR) is a large pool type concept of industrial SFR developed within the Collaborative Project on European Sodium Fast Reactor (CP-ESFR) of the 7th Euratom Framework program of the European commission [1]. Prototype Fast Breeder Reactor The PFBR is a 500 MWe, sodium cooled, pool type, mixed oxide (MOX) fuelled reactor having two secondary loops. Volume 7 (2008). The reactor will use mixed-oxide (MOX) fuel with 100 GWd/t burnup, and will feature two coolant loops producing steam at 480°C. ?514 ??? The invention discloses an accidental afterheat discharge system of a pool type SFR. The existing sodium cooled fast reactors (SFR) have two types of designs – loop type and pool type. ?8 Pool type sodium-cooled fast reactor (SFR) The sodium-cooled fast reactor ( SFR ) is a Generation IV reactor project to design an advanced fast neutron reactor . ?8 BN-600 - a pool type sodium-cooled fast breeder reactor at the Beloyarsk Nuclear Power Station. 4. In improving the nuclear and thermal-hydraulic performance of the reactor, it is important to consider the geometry of the assembly. 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. ?2 9. the accident afterheat exhausting system of pool type natrium cold fast reactor according to claim 8, it is characterized in that: described each loop is provided with independently feed circuit. ?0.525 The used air heat exchanger 3 of present embodiment is a kind of non-active sodium-air heat exchangers.It comprises cylindrical shell, and cylinder top is provided with outlet air door 2, and the bottom is provided with import air door 4.The top of cylinder lumen is provided with expansion drum, expansion drum is fixed on the cylindrical shell by support plate, the expansion drum top is provided with the argon gas entrance sleeve, the argon gas entrance sleeve extends to outside the cylindrical shell, the expansion drum bottom is communicated with sodium inlet pipe, the cylindrical shell of expansion drum is communicated with the heat exchanger tube tube bank, and the heat exchanger tube tube bank is communicated with the lower header device.Wherein, import air door 4 is designed to 3 single hops, and outlet air door 2 is designed to 1 two section.One in 3 import air doors breaks down, and when in two elementary sections of outlet air door one was broken down, this device still can be effectively discharges the residue heat release of reactor core.The air door of air heat exchanger 3 or air door unit are provided with electronic and manual two kinds of drive units, and be provided with two independently feed circuit, serve two in this device independently the import air door 4 of air heat exchanger 3 and the electric actuator and the damper positions sensor of outlet air door 2 in the loop respectively, and comprise independent current source, as battery pack, diesel-driven generator etc. Sodium has only one stable isotope, sodium-23. 3.
