- the invention relates to systems for localization and cooling of the core melt of a nuclear reactor, intended for the localization of severe beyond design basis accidents, in particular, to devices for directing the core melt of a nuclear reactor into a melt trap.
- melt trap which, after the core melt enters it, prevents damage to the hermetic shell of the nuclear power plant and, thereby, protects the population and the environment from radiation exposure in severe accidents of nuclear reactors by cooling and subsequent crystallization of the melt.
- the core melt After the reactor vessel is melted, the core melt enters a guiding device, which is usually made in the form of a funnel mounted on a console truss, and is designed to change the direction of the melt flow from the place of its outflow from the reactor vessel towards the axis reactor mines, in order to ensure the flow of the melt to the service site. Burning through the service platform, the melt enters the melt trap, where it interacts with the filler, gradually heating the body of the melt trap. In this case, when the reactor vessel is melted, a complete separation of the vessel bottom can occur, as a result of which the reactor vessel bottom falls onto the guide device, exerting a high shock load on it.

- the guiding device works as follows.
- the power frame used as part of the guiding device (1) of the system for localizing and cooling the core of a nuclear reactor performs shockproof, stabilizing, channel-forming and protective functions when the core melt flows out of the vessel (17) of a nuclear reactor or the bottom falls (16) the vessel (17) of the reactor with a part of the core melt or debris of the bottom and debris of the internals.
- the shockproof functions of the load-bearing frame are performed by force ribs (5), which provide damping of the shock load from the side of the detached bottom (16) of the reactor vessel (17) with the core melt or the detached sectors of the destroyed bottom, taking into account the acceleration created by the residual pressure inside the vessel (17) of the reactor.
- the position of the force ribs (5) to perform shockproof functions should be as close as possible to the bottom (16) of the reactor vessel (17), in this case the impact force of the bottom (16) of the vessel (17) of the reactor with the core melt in it or the impact force of fragments the bottom of the power ribs (5) will be minimal.
- the impact force increases significantly, and the applied load on the power ribs (5) is redistributed as follows: at a minimum distance, the unevenness of the bottom separation (16) the vessel (17) of the reactor or its parts has little effect on the difference in mechanical loading experienced by the force ribs (5), these loads are approximately the same, with an increase in the distance, the difference in the mechanical loading of the force ribs (5) begins to increase, and with a large distance between the force ribs ( 5) and the bottom (16) of the vessel (17) of the reactor, the shock load can fall entirely on one or two force ribs (5), which is associated with the rotation of the bottom (16) of the vessel (17) of the reactor during its movement, due to the initial irregularity (non-uniformity ) separation of the bottom (16) in the azimuthal direction from the reactor vessel (17).
- the first optimal distance between the bottom (16) of the reactor vessel (17) and the load-bearing ribs (5) for damping the shock load at the first touch of the bottom or its parts is from 50 to 250 mm.
- the limitation on the minimum value is determined by the thermal expansion of the reactor vessel (17) during normal operation, and the limitation on the maximum value is determined by the limiting angle of rotation of the bottom (16) after separation from the reactor vessel (17) and the accumulated acceleration under the influence of the residual pressure in the reactor vessel (17) ...
- the second optimal distance between the bottom (16) of the reactor vessel (17) and the power ribs (5) for damping the shock load at the second touch, taking into account the rotation of the bottom (16) or its parts, is from 200 to 800 mm.
- the minimum and maximum values are determined by the number of power ribs (5), their impact strength and ductility. With equal impact strength of the power ribs (5), the smaller there are, the smaller the distance is needed for the second touch, and the larger the power ribs (5), the greater the distance to the second touch.
- the first and second optimal distances between the bottom (16) of the reactor vessel (17) and the power ribs (5) determine the shape of the surface of the power ribs (5) facing the bottom (16) of the reactor vessel (17).
- For smaller values of the optimal distance of the surface of the force ribs (5) perform in an elliptical shape (18), as shown in Fig. 3. With this shape, the axial distances between the radial points (19 and 20) of the first and second tangencies on the force ribs (5) and the corresponding radial points (21 and 22) on the bottom (16) of the reactor vessel (17) slightly differ from each other.
- the first and second paired points (19, 21 and 20, 22, respectively) of tangencies on the radial edges (5) are practically equidistant from the axial axis D in the radial direction. And for large values of the optimal distance, the surfaces of the force ribs (5) are made in the form of a straight line (23) with a constant angle of inclination relative to the axial axis D, as shown in Fig. 4.
- the first condition is that the second optimal distance between the bottom (16) of the reactor vessel (17) and the power ribs (5) for damping the shock load must be greater than the first optimal distance by at least 1, 1 times, but not more than 8 times , which is determined by the conditions of rotation of the detached bottom (16) and its large fragments.
- the second condition is that the radial location of the paired point (20, 22) of the second touch on the force edge (5) must be farther from the axial axis D than the radial location of the paired point (19, 21) of the first touch. This means that the paired point (19, 21) of the first contact of the detached bottom on the force rib (5), i.e. the point of the first impact should be closer to the axis D of symmetry than the point (20, 22) of the second contact, i.e. the point of the second impact as a result of a turn of the bottom or its large fragments during movement.
- the supporting functions of the load-bearing frame are performed by the outer upper power shell (9), the middle power shell (10), and the outer lower power shell (11) together with inclined plates (13, 14), which ensure the reception and redistribution (equalization) of static and dynamic power loads, acting from the power edges (5).
- an external upper power shell (9) and an internal power shell (8) are used to secure the radial power ribs (5).
- the inner power shell (8) forms a central channel for moving the core melt and is a limiter for large fragments of the bottom (16) of the reactor vessel (17) falling into the trap, and the outer upper power shell (9) provides axial stability of the force ribs (5) in during the entire process of interaction of the guiding device with the core melt and the bottom (16) of the reactor vessel (17).
- the first condition is strength and stability in the azimuthal direction, which are determined by the distance L (as shown in Fig. 1) between the power ribs (5), which transmit the load from the bottom (16) of the reactor vessel (17) to the outer upper power shell (9) ...
- the optimal distance L between the power ribs (5) along the perimeter of the outer upper power shell (9) is from 0.7 to 1.3 m, depending on the thickness of the force rib (5), moreover, the diameter of the outer upper power shell (9) is in the range from 4 to 6 m, practically does not affect the value of this distance L.
- the load-bearing ribs (5) with inclined plates (13, 14), the outer upper power shell (9), the middle power shell (10), the outer lower power shell (11) provide damping of the shock load from the side of the torn-off bottom (16 ) the vessel (17) of the reactor with the core melt or torn-off sectors of the destroyed bottom (16) with the debris of the internals, and, as a consequence, provide deceleration and blocking of large fragments of the vessel (17) and its internals, ensuring a consistent flow of core melt, debris of internals and the bottom (16) of the body (17) of a nuclear reactor into a melt trap.
- the stabilizing functions of the load-bearing frame are performed by the upper inclined plate (13) and the lower inclined plate (14).
- the upper inclined plate (13) connects the middle power shell (10) with the conical bottom; (15).
- the lower inclined plate (14) connects the outer upper power shell (9) with the conical bottom (15).
- Inclined force plates (13, 14) ensure the axial stability of the force ribs (5) in the process of redistribution of shock mechanical loads and are guiding elements that ensure a given direction of flow of the core melt from the reactor vessel (5) into the melt trap.
- the angle of inclination of the force plates (13, 14) in the radial direction is chosen so as to provide an equal area at the entrance to each sector formed by the inclined plate (13, 14) and two force ribs (5), and at the exit from each sector.
- the flow section in the direction of flow of the core melt at the entrance to the sector will be located horizontally (24), and at the exit from the sector - vertically (25), which determines the position of the horizontal force plates at the base of the force frame.
- the flow area of the sectors is selected based on a given flow rate of the first salvo portion of the core melt entering the trap during lateral penetration of the reactor vessel (17).
- an additional inclined plate can be installed between the upper inclined plate (13) and the lower inclined plate.
- the inclined plates (13, 14) due to their own destruction at each level, provide an increase in the flow area of the sectors of the load-bearing frame and, as a consequence, provide an increase in the flow rate when the core melt flows from the reactor vessel (5) into the trap.
- inclined plates (13, 14) and radially oriented force ribs (5) provide axial stability of force ribs (5) in the process of redistribution of shock mechanical loads and provide a given direction of flow of the core melt from the reactor vessel (17) into the melt trap.
- the channel-forming functions of the load-bearing frame together with inclined plates (13, 14) are performed by radially oriented load-bearing ribs (5), which provide the throughput of the flow section of the sectors during lateral penetration of the reactor vessel (17).
- radially oriented load-bearing ribs (5) which provide the throughput of the flow section of the sectors during lateral penetration of the reactor vessel (17).
- the contact of the bottom (16) of the vessel (17) of the reactor with the power ribs (5) leads to the development of one of two scenarios.
- the bottom (16) breaks in the zone located between the force ribs (5), or collapses with the formation of a crack, and the melt flows out through the rupture zone.
- the bottom (16) does not collapse, and continues to deform plastically in the space between the radial force ribs (5).
- the second case is the most dangerous, since the bottom (16) of the vessel (17) of the reactor in this case is capable of completely blocking the flow section of the sectors of the load-bearing frame and blocking the core melt during lateral penetration of the vessel (17) of the reactor.
- the optimal ratio of the total thickness of the power ribs (5) to the circumference of the outer upper power shell (9) is from 4 to 8%, and the number of power ribs (5) varies in the range from 8 to 16.
- the installation depth of the inclined plates (13 , 14) is in the range from 200 to 400 mm from the outer edge of the force rib (5) facing the bottom (16) of the reactor vessel (17), in the critical section having the lowest boundary that the outer surface of the bottom (16) can reach body (17) without destruction in the sectors between the radial power ribs (5).
- inclined plates (13, 14) and radially oriented load-bearing ribs (5) provide the throughput of the flow section of the sectors during lateral penetration of the reactor vessel (17) and, as a consequence, protect the building and serpentinite concrete of the reactor shaft from interaction with the melt.
- the protective functions of the power frame are performed by the middle power shell (10), which ensures the distance of the outer upper power shell (9) from the effect of the outflowing core melt.
- V Depending on the thickness, from 1 to 2 medium power shells (10) can additionally be installed, which, due to their own destruction, protect the outer upper power shell (9) and the outer lower power shell (11).
- the middle power shell (10) protects the upper power shell from destruction by the core melt and, as a consequence, the protection of the construction and serpentinite concrete of the reactor shaft from interaction with the melt.
- a power frame as part of the guiding device made it possible to ensure a gradual flow of corium (melt) after the destruction or penetration of the reactor into the melt trap and to ensure the retention of large-sized fragments of internals, fuel assemblies and the bottom of the reactor vessel from falling into the melt trap. As a result, this made it possible to increase the efficiency of localization and cooling of the core melt of a nuclear reactor by eliminating the instantaneous ingress of the melt into the trap.
