The assembly according to claim 1, wherein a surface area of the fluid tight seal, formed between the removable seating piece (11) and a lower periphery of the head (10) of the valve, is less than a surface area of the second conical ramp (24). 7. The assembly according to claim 4, wherein the first conical ramp (23) forms an upper edge of the central opening (25) and also forms a watertight contact with a lower portion of the head (10) of the valve, the first conical ramp (23) and the second conical ramp (24) together define a flow ramp, andthe second conical ramp (24) has a smaller slope than the first conical ramp (23). 8. The drainage assembly according to claim 1, wherein the seating piece (11) has an annular internal framework. 9. The drainage assembly according to claim 1, wherein upper and lower surfaces of the seating piece (11) each have an annular external framework (27) which comprises one of a reinforced area and a peripheral disc. 10. The drainage assembly according to claim 3, wherein the body (13) of the drainage assembly radially surrounds the seating piece (11). 11. The drainage assembly according to claim 1, wherein the head (10) of a movable valve element of the drainage assembly extends upward into a cylindrical portion of the reactor. 12. The drainage assembly according to claim 1, wherein an upper portion of the head (10) houses a temperature sensor (23). 13. The drainage assembly according to claim 1, wherein the head (10) terminates in a surface that is substantially flush with a bottom of the reactor when the head (10) of the movable valve element of the drainage assembly is in the open position. 14. The drainage assembly according to claim 1, wherein a conical base surface of the head (10) of the movable element on the drainage assembly abuts against and forms the fluid tight seal with the seating piece (11). 15. The drainage assembly according to claim 1, wherein the removable seating piece (11) is enclosed by a metal fireproof rim (38) which increases an amount of time that the seating piece (11) of the drainage element remains effective in facilitating fluid retention in an event of a fire. 16.
