- the invention relates to the field of nuclear energy, in particular, to auxiliary devices for nuclear power plants, namely, to devices for installing external thermal insulation of a nuclear reactor vessel, and can be used at nuclear power plants to carry out recovery annealing of welds and (or) base metal VVER reactor vessels.
- the problem to be solved by the claimed invention is to ensure the possibility of mounting and dismantling the thermal insulation of the outer surface of the VVER reactor vessel in the cramped conditions of the sub-reactor room and an increased level of ionizing radiation.
- the technical result of the present invention is to reduce the temperature gradient across the thickness of the nuclear reactor vessel by thermal insulation of the outer surface of the reactor vessel, to ensure the uniformity of the physical properties of the metal and welds of the reactor vessel and to reduce the effect of thermal effects on the surrounding structures during the recovery annealing of welds and (or) the base metal VVER reactor vessels.
- the device for installing the external thermal insulation of the nuclear reactor vessel includes a movable transport trolley equipped with a mechanism for its movement, a removable bearing rim located on the movable transport trolley, on which the thermal insulation of the reactor vessel is fixed, at least two lifts located with opposite sides of the reactor vessel at the level of its upper part, while the removable bearing rim is connected to the lifters with the possibility of raising and lowering it.
- the thermal insulation of the nuclear reactor vessel is predominantly made in the form of rolled heat-insulating mats and heat-insulating blocks fixed on the upper end of the removable bearing rim.
- the removable bearing rim can be made in the form of at least two sectors, pivotally connected with each other with the possibility of folding and unfolding, while on the outer surface of the bearing rim a stacked rail can be fixed, on which removable carriages are mounted with the ability to slide with suspended on them with rolled thermal insulation mats.
- Heat-insulating blocks can be made in the form of triangular sheets of mullite-silica cardboard fixed on metal frames. Along the edges of the rolled heat-insulating mats, strips of silica fabric are predominantly made, covering the gaps between adjacent rolled heat-insulating mats.
- the movable transport trolley can be installed on wheel pairs and contain stands, the upper free ends of which are connected by a beam, on which two pivot frames are mounted with the possibility of rotation through 90 °, equipped with supporting half rings and a mechanism for folding them into a vertical position.
- the removable bearing rim is predominantly located on the supporting half-rings of the rotating frames of the movable transport carriage.
- the movable transport trolley can contain a locking mechanism, and the hoists can contain cable winches with ropes and be equipped with locking mechanisms.
- FIG. 1 shows a general view of the device (lifters are not shown), FIG. 2 - a movable transport carriage, in Fig. 3 - removable bearing rim, FIG. 4 - device diagram before installing thermal insulation; in fig. 5 is a diagram of the device after installing thermal insulation.
- a device for installing external thermal insulation of a nuclear reactor vessel includes a movable transport trolley 1, a removable bearing rim 2 and lifts 3 (Figs. 4 and 5).
- Transport trolley 1 is installed on the rail track on wheel pairs, one of which is leading and has a drive.
- the transport cart 1 contains racks 4, the upper free ends of which are connected by a beam 5, on which two pivot frames 6 are pivotally mounted with the possibility of rotation by 90 °, equipped with support half rings 7 and a mechanism for their rotation (folding) into a vertical position.
- Transport trolley 1 is equipped with a locking mechanism that fixes its position on the rail track.
- a removable bearing rim 2 is installed on the supporting half-rings 7 of the movable transport trolley 1. Thermal insulation is made in the form of rolled heat-insulating mats 8 and heat-insulating blocks 9.
- Removable bearing rim 2 is made in the form of two sectors (half rings), hingedly connected to each other with the possibility of vertical folding and unfolding in a horizontal position.
- a type-setting rail 10 is fixed, on which removable carriages with rolled heat-insulating mats 8, made of silica fabric and designed to create a uniform heat-insulating layer around the reactor vessel, suspended from them, are mounted with the ability to slide.
- the heat-insulating mats 8 are wound in rolls and fixed in a rolled state with the help of loops of silica fabric and metal buttons.
- Rolled heat-insulating mats 8 have at the edges of the tape made of silica fabric, closing in the working position of the gaps between adjacent mats 8.
- heat-insulating blocks 9 are fixed using quick-detachable joints, made in the form of triangular-shaped sheets of mullite-silica cardboard fixed on metal frames, designed to create a uniform heat-insulating layer that protects the conical part of the support truss 11 of the reactor vessel 12 from thermal effects in the working condition of the device during the recovery annealing of the reactor vessel 12.
- a device for installing external thermal insulation of a nuclear reactor vessel operates as follows.
- the lifters 3 are fixed from opposite sides of the reactor vessel 12 at the level of its upper part.
- the ropes 13 of the hoist winches are lowered down along the reactor vessel 12.
- a removable bearing rim 2 is installed on the supporting half rings 7 of the transport trolley 2.
- heat-insulating blocks 9 are fixed using quick-detachable connections, while the heat-insulating blocks 9 located above the hinge loops of the removable bearing rim (4 pcs.) Are not installed ...
- the transport trolley 1 with the bearing rim 2 is moved in the folded state along the rail track into the under-reactor room.
- Transport trolley 1 with a supporting rim is installed under the reactor vessel 12 in its center.
- the transport trolley 2 is fixed on the rail track, and then, using the rotation (folding) mechanism, the support half rings 7 with the sectors (half rings) of the removable carrier rim 2 are laid out in a horizontal position.
- clamps are installed to prevent them from folding.
- heat-insulating blocks 9 (4 pcs.) are additionally fixed.
- roll-up heat-insulating mats 8 are hung, fixed in a folded state with the help of loops of silica fabric and metal buttons. After the completion of the hinge of the rolled thermal insulation mats 8, the metal buttons of the fixing loops are unbuttoned to ensure the possibility of free unwinding of the rolled thermal insulation.
- the removable bearing rim 2 is lowered by means of lifters 3 onto the transport trolley 1, the ropes 13 are disconnected from the removable bearing rim 2, and the thermal insulation is dismantled. Then, in the places of the hinged connection of the sectors (half rings) of the removable carrier rim 2, the locks are removed to prevent their folding, and the support half rings 7 are folded with the sectors of the carrier rim 2 into a vertical position. Next, the transport trolley 1 with a removable carrier rim 2 is moved along the rail track from the sub-reactor premises in a room for decontamination, maintenance and storage.
- the use of the claimed invention will provide the possibility of mounting and dismantling the thermal insulation of the outer surface of the VVER reactor vessel in the cramped conditions of the under-reactor room and an increased level of ionizing radiation.
- Thermal insulation of the outer surface of the reactor vessel ensures a decrease in the temperature gradient over the thickness of the nuclear reactor vessel, the uniformity of the physical properties of its metal and welds, as well as a decrease in the influence of thermal effects on the surrounding structures during the recovery annealing of welded seams and (or) the base metal of the VVER reactor vessel.
