FIRST WALL OF NUCLEAR FISSION EQUIPMENT

PURPOSE:To enable exchange of an armor tile alone or an integralassembly of the armor tile and armor mounting seat with an operation only from the plasma side by bolting the armor mounting seat on a supporting base plate freely attachably and detachably from the plasma side. CONSTITUTION:The armor mounting seat 6 having a construction separate from the supporting base plate 7 is fastened and fixed by means of the 1st bolts 9 to the plasma side of the supporting base plate 7. The armor tile 4 and the armor mounting seat 6 are fastened by means of the 2nd bolt 5a from the plasma side or counter plasma side. Not only the exchange of the armor tile 4 in an ordinary occasion can be made but also the exchange of the armor tile 4 and the armor mounting seat 6 can be easily made only with the operation from the plasma side by mechanically breaking down the armor tile 4 or previously providing a through-hole to the armor tile 4 even if the armor tile 3 or the 2nd bolt 5a for armor mounting is broken. The reliable operation for exchanging the armor tile is thus enabled.
