Embodiment Construction
[0057] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0058] The composition and structure of the reactor core molten material capture device of the exemplary reactor pit direct retention of the present invention is as follows: Figure 1-4 As shown, it includes a reactor pit 1, a reactor pressure vessel 2, a steam discharge port 3, a cooling water tank 4, an inspection platform 5, a shock absorbing device 6, and a metal sealed tank 7.
[0059] The maintenance platform 5 is placed in the pit pile 1 and divides the pit pile 1 into upper and lower halves. The maintenance platform 5 is spliced by glass plates with high mechanical strength (the glass plates have a structure of 2-4 layers, which are bonded with glass glue, and the thickness of each tempered glass plate is 10-15mm, and the load-bearing per unit area is not less than 1700kg). , and a layer of sacrificial concrete with a t...
