Härigenom kan uppnås att ett spel er- hålles mellan behållaren och utfyllnadskz-oppen i samband med svalningen. Fram» ställes behållarens cylinder och lock av ett material med hög halt av aluminium- oxid, Al205, kan utfyllnadshoppen lämpligen vara tillverkad av ett material med hög halt av magxesiumoxid, MgO. Utfyllnadslcroppen kan vara homogen :nen kan också. bestå av en kärna. av ett keramiskt material som är omgiven av ett relativt tjockt metallhölje. I en sådan sammansatt utfyllnadskropp kan man uppnå. den önskade större utvidgningskoefficienten även om lcärnan består av samma material som bef- hållarens väggar. Den önskade effekten kan uppnås om' tjockleken hos höljet om- lming kärnan består av rostfritt stål med 18 QÉ krom och 8 73 nickel. Godstjock- leken bör då lämpligen vara 2,5 7:3 till 5 fië av utfyllnadslcroppens diameter. Uppfimiingen beskrivas närmare under hänvisning till bifogade figur. I denna visas den ände av en cylinder, som skall hemetiskt tillslntas med ett lock. I figuren betecknar 50 avfallsbehållare, som består av en keramikcylinder 51 med ett kupolformat lock 52. I denna är anbringade ett antal glascylindrar 55. Dessa kan vara inbäddade i ett pulver 54. Vid cylinderns övre del är anbringad en stödkropp 55 som under hopsintringen av cylindern 51 och locket 52 förhindrar deformation av cylinder och lock. Mellan cylindern 51 och locket 52 kan anbringas ett pulverskikt 42, som vid pressnirïgen sintrar 'samman med lock och cylinder. Behållaren 50 omges av en plåtcylinder 57 och enplåtkåpa 58, som är förenade med en svets 40. Utfyllnadshoppen 55 'består av en keramisk kär-na 55a omgiven av ett plåthölje 55b. PATEIFPKRAV 1.

Sätt enligt patentlcrav1, k ä n n e t e c k n a. t därav, att vid en kapsel med cylinder (51) och lock (52) utförd av ett material med hög A120?- halt användes en utfyllnadslmopp (55) utförd av ett material innehållande en hög halt N50. ,..__,_.,.,f, ___-_ I, ma, H.._.,,_.__ .U ....._._-. ..._ 7711709-'1 5. Sätt enligt patentkrav 1, k ä n n e t e c k n a t därav, att utfyllnads- kroppen är uppbyggd av ett tjockt hölje av en metall (55b) fylld med ett mate- rial (55a) med i huvudsak samma sammansättning som materialet i cylindern (51) och locket (32). ANFÖRDA PUBLIKATIONER:1. \ wwmur fl- * fl vcïz-: nr-.vuu-rer-: vv-u- 10 15 20 _7711'709-1 a support element of a material with a coefficient of expansion greater than that of the container material is inserted. In this way it can be achieved that a play is obtained between the container and the filling k-open in connection with the cooling. If the cylinder and lid of the container are made of a material with a high content of alumina, Al2 O5, the filling hopper can suitably be made of a material with a high content of magnesium oxide, MgO. The filler body can be homogeneous: it can also. consist of a core. of a ceramic material surrounded by a relatively thick metal casing. In such a composite filling body one can achieve. the desired larger expansion coefficient even if the core consists of the same material as the walls of the container. The desired effect can be achieved if the thickness of the casing around the core consists of stainless steel with 18 QÉ chromium and 8 73 nickel. The thickness of the material should then suitably be 2.5 7: 3 to 5 fi ë of the diameter of the filling body. The invention is described in more detail with reference to the accompanying figure. This shows the end of a cylinder which is to be hemetically aligned with a lid. In the figure, 50 denotes waste containers, which consist of a ceramic cylinder 51 with a dome-shaped lid 52. In this are arranged a number of glass cylinders 55. These can be embedded in a powder 54. At the upper part of the cylinder is attached a support body 55 which during the sintering of the cylinder 51 and the lid 52 prevent deformation of the cylinder and lid. A powder layer 42 can be applied between the cylinder 51 and the lid 52, which sinks together with the lid and cylinder during the pressing. The container 50 is surrounded by a plate cylinder 57 and a single plate cover 58, which are connected to a weld 40. The filling hopper 55 'consists of a ceramic core 55a surrounded by a plate casing 55b. PATIENT REQUIREMENT 1. A method according to claim 1 in Swedish patent 7704488-1 for enclosing used highly active nuclear fuel or high-level waste from the environment, characterized in that at the opening of the cylinder (51) an s-dead element (55) with a larger coefficient of expansion the material in the cylinder (51) and lid (52) of the canister. 2. A method according to claim 1, characterized in that in a capsule with cylinder (51) and lid (52) made of a material with a high Al 2 O 2 content, a filling mop (55) made of a material containing a high content of N50. , ..__, _.,., f, ___-_ I, ma, H .._. ,, _.__ .U ....._._-. 5. A method according to claim 1, characterized in that the filling body is built up of a thick casing of a metal (55b) filled with a material (55a) having substantially the same composition. as the material of the cylinder (51) and the lid (32).
