Abstract
1441539 Sodium-cooled integrated fast-reactor with siphon COMMISSARIAT A L'ENERGIE ATOMIQUE 9 Oct 1974 [18 Oct 1973] 43768/74 Heading G6C In a sodium-cooled, integrated, fast-reactor of the type comprising a main reaction vessel 10, Fig. 1, in which hot sodium 21 enters a primary heat exchanger 26 and is returned beneath a shell 24 as cold sodium 22 which is then re-circulated by pumping through a passage 28 into a lower portion of the reactor core fuel assemblies 12, there is provided at least one assembly of cylindrical shells 50, 52, 56 Fig. 2, co-axial with the reaction vessel 10 and so arranged as to form a two-branch siphon interposed between the hot sodium 21 and the main vessel wall 10 in at least the upper portion of the vessel, the two branches 58 and 60 of the siphon being directed towards the bottom of the reactor with the branch 58 being supplied with cold sodium. Cold sodium is also uspplied to an annular space 72. The siphon is started by applying a negative pressure of argon in a chamber 62 through pipes 66, 66<SP>1</SP> and an annular manifold 68. Self-regulation of the sodium level in the chamber 62 in response to reactor power variations is effected by virtue of the fact that when the level of the hot sodium rises the argon in the chamber 62 is compressed and limits the rise in the level of the cold sodium and when the hot sodium level drops the reduction in pressure of the argon limits the drop in level of the cold sodium. This action prevents the creation of a deep stagnant layer of sodium above the top 54 of the shell 52 which layer can become hot with heat rediated from the hot sodium 21. In another embodiment, Fig. 4 (not shown), one arm of the siphon is constituted in part by the wall of the main vessel and the annular space 72 is omitted. In a further embodiment (Fig. 3, not shown) the siphon is again started with a negative pressure of argon but thereafter no argon is allowed to remain in the siphon and the creation of a stagnant layer of sodium is prevented by arranging for the bend of the siphon to be sufficiently narrow.
