1. A storage structure for storing waste of nuclear plants comprising a plurality of tubular waste storage members, each of said plurality of tubular members being adapted to form one or a plurality of waste storing chambers wherein (a) each of said plurality of tubular storage members is provided near the bottom thereof with at least three horizontal bolts for locking and supporting the storage members in a fixed position for storing waste of all nuclear plants the longitudinal axes of the bolts intersecting at a common point of said axes; wherein  (b) a plurality of support plates for each of said plurality of tubular storage members is provided at the lower end of each of said plurality of storage members; wherein  (c) each of said plurality of support plates has a plurality of upstanding portions equal in number to the number of bolts on one of said plurality of storage tubes; wherein  (d) each of said plurality of upstanding portions of said plurality of support plates is provided with an open recess for insertion into one of said plurality of bolts; wherein  (e) each recess is wide at the open end thereof and bounded by downward slanting surfaces of decreasing spacing; and wherein  (f) each recess has a lower closed end which forms a substantially circular bolt-bearing surface coaxial with one of said plurality of bolts  (g) wherein the longitudinal axis of each bolt intersects the center longitudinal axis of said tubular storage member, and wherein each bolt is disposed at a corner of said tubular storage member.  (a) each of said plurality of tubular storage members is provided near the bottom thereof with four bolts; and wherein  (b) each of said plurality of support plates has four sides of equal length and four upstanding portions of equal length of which each upstanding portion is provided with one open recess.  (a) each recess is asymmetrical; wherein  (b) each recess is formed by a relatively long portion and by a relatively short portion of one of said plurality of upstanding portions of one of said plurality of support plates; and wherein  (c) said relatively short portion projects at least to the center of said substantially circular bolt-bearing surface to lock one of said plurality of bolts in position.  (a) said tubular member is provided near the bottom thereof with at least three horizontal bolts the longitudinal axes of al the bolts intersecting at a point common to said longitudinal axes; wherein  (b) said tubular member is supported by a first circular plate having a plurality of angularly displaced upstanding portions each for supporting one of said plurality of bolts; and wherein  (c) each of said upstanding portions is provided on the upper edge thereof with an open recess, said recess including a relatively wide slanting entrance portion for inserting one of said at least three bolts therein, and said recess further including a substantially circular relatively narrow bottom portion coaxial with one of said plurality of horizontal bolts; and wherein  (d) the longitudinal axis of each bolt intersects the center longitudinal axis of said tubular member, and wherein each bolt is disposed at a corner of said tubular member.  (a) said tubular member is closed at the bottom thereof by a second plate parallel to said first circular plate, said second plate being perforated for the admission of a cooling medium to said chambers; and wherein  (b) spacing means are interposed between said first plate and said second plate. 2. A storage structure as specified in claim 1 wherein 3. A storage structure as specified in claim 1 wherein the bottom of each of said plurality of tubular storage members is closed by a perforated plate for admission of cooling fluid to said chambers, and wherein said bolts are affixed with one end thereof to said perforated plate. 4. A storage structure as specified in claim 1 wherein 5. A storage structure as specified in claim 1 wherein each of said plurality of tubular storage members is rectangular in cross-section and wherein each of said plurality of horizontal bolts is arranged in the direction of the diagonals of one of said plurality of tubular storage members. 6. A storage structure as specified in claim 1 wherein the surface, which is bounding said open recess, has a nose-like projection that extends at least to the vertical median plane of one of said plurality of bolts to lock said one of said plurality of bolts in position against the action of upward directed forces. 7. A storage structure for waste of nuclear plants comprising a tubular member adapted to form one or more waste receiving chambers wherein 8. A storage structure as specified in claim 7 wherein
