Apparatus for the positioning of a submarine channel (2) comprising elements assembled end-to-end on board a transporter such as a platform or a ship (1) equipped for this purpose and in which the channel (2) is gradually released in a substantially vertical direction during the course of assembly of the said elements which are connected end-to-end to the extremity of the part of the channel which has already been released, the said apparatus being of the type comprising at least one loading mast capable of swinging between a substantially horizontal position and a substantially vertical position, at least one positioning mast equipped with engagement and displacement means which permits a channel elements (4, 9) loaded on to it to be engaged and displaced in a direction parallel to it and substantially vertically, control means for the said engagement and displacement means capable of lowering the said channel element under a substantially constant tension independent of pounding movements of the transporter and substantially coaxial with the free end of the part of the channel (2) which has already been released, gripping and supporting (21, 22) means for the said end, as well as control means for the said gripping and supporting means which are capable of supporting the said end under a substantially constant tension independent of pounding movements of the transporter, the said apparatus being characterised in that in order to simplify and accelerate the operations in positioning the channel, the loading mast and the positioning mast are merged, and two such masts (5, 7) are provided to operate alternately, these masts being capable of being arranged substantially horizontally, one in a direction of the transporter and the other in the opposite direction.

Description

Opphengningssystem for kjernereaktorers trykkhylster. Suspension system for nuclear reactor pressure jackets.

Denne oppfinnelse vedrører oppheng-ningsorganer for kjernereaktorer inneslut-tet i et trykkhylster som er utsatt for sterke temperaturforandringer under drift. This invention relates to suspension devices for nuclear reactors enclosed in a pressure envelope which are exposed to strong temperature changes during operation.

Oppfinnelsen skaffer nye organer til å The invention provides new organs to

henge opp, understøtte og bære trykkhylsteret eller huset i en anordning av denne art, hvor det ikke kreves lokale fortyknin-ger i beholderveggen og hvor alle radiale belastninger opptas såvel som store for-skjeller i varmeutvidelsen mellom hylster og dets opplagringsring, samtidig som enhver annen bevegelse for hylsteret er be-grenset. suspend, support and carry the pressure casing or housing in a device of this kind, where no local thickening is required in the container wall and where all radial loads are taken up as well as large differences in thermal expansion between the casing and its storage ring, at the same time as any other movement of the holster is limited.

Disse og andre trekk og fordeler ved oppfinnelsen vil fremgå av den etterføl-gende detaljerte beskrivelse av en fore-trukket utførelsesform for oppfinnelsen vist på de medfølgende tegninger, hvor: Fig. 1 viser et sideriss av en kjerne-reaktor opphengt ved hjelp av oppheng-ningsorganene ifølge oppfinnelsen, idet en-kelte deler er bortbrutt for å lette illustra-sjonen. Fig. 2 viser i større målestokk en detalj ved utførelsen ifølge fig. 1 i nærheten av opphengningslabbene. Fig. 3 viser et snitt lagt etter linjen 3—3 i fig. 2. Fig. 4 viser detaljer ved en oppheng-ningslabb som bæres av hylsteret, sett i sideriss. Fig. 5 viser en detalj ved en spesiell These and other features and advantages of the invention will be apparent from the following detailed description of a preferred embodiment of the invention shown in the accompanying drawings, where: Fig. 1 shows a side view of a nuclear reactor suspended by means of suspension the ning devices according to the invention, with some parts being broken away to facilitate the illustration. Fig. 2 shows on a larger scale a detail of the design according to fig. 1 near the suspension lugs. Fig. 3 shows a section laid along the line 3-3 in fig. 2. Fig. 4 shows details of a suspension tab which is carried by the holster, seen in side view. Fig. 5 shows a detail of a special

labb som muliggjør innføring av en låse-kabel. tab that enables the introduction of a locking cable.

Idet det henvises til fig. 1, bæres sideveggen 10 i trykkhylsteret for en reaktor av en opphengningsring 12 ved hjelp av et flertall1 bøyelige opphengningsbånd 14 som løper ned fra opphengningen 12. Som vist heri er sideveggen 10 sylindrisk og for-løper inne i den sirkelformete opphengningsring 12, idet opphengningsringen selv bæres av en ytre reaktorbærende sylinder (ikke vist). Referring to fig. 1, the side wall 10 in the pressure envelope for a reactor is supported by a suspension ring 12 by means of a plurality of flexible suspension bands 14 which run down from the suspension 12. As shown herein, the side wall 10 is cylindrical and extends inside the circular suspension ring 12, the suspension ring itself is carried by an outer reactor-carrying cylinder (not shown).

Hylsteret 10 er forsynt med en rekke omkretslabber 16 som er fordelt rundt hylsterets omkrets så at det mellom disse .opptar labber 18 tildannet på de nedre ender av båndene 14. Labbene 16 er fastgjort til hylsteret 10 ved sveising, som vist i fig. 4, og har med sine nedre ender en fremspringende flens 20 med en innervegg 21 som ligger i avstand fra hylsterets sidevegg så at det dannes et spor 22. Labbene 18 på endene av båndene 14 har høyre og venstre utvidelser 24 og 26 så at det ved deres nedre ender dannes et T-formet parti. Forlengelsene 24 og 26 på hver av labbene 18 opptas i sporene 22 i to nabolabber 16. Det vil bemerkes ut fra fig. 2 at bredden på labbene 18 er slik at de opptas løst mellom to nabolabber 16 og at forlengelsene 24 og 26 ligger an mot bunnene 23 av sporene 22. The sleeve 10 is provided with a number of circumferential tabs 16 which are distributed around the circumference of the sleeve so that between these, tabs 18 formed on the lower ends of the bands 14 are received. The tabs 16 are attached to the sleeve 10 by welding, as shown in fig. 4, and has at its lower ends a projecting flange 20 with an inner wall 21 which is spaced from the side wall of the casing so that a groove 22 is formed. The tabs 18 on the ends of the bands 14 have right and left extensions 24 and 26 so that at their lower ends form a T-shaped part. The extensions 24 and 26 on each of the legs 18 are accommodated in the grooves 22 in two neighboring legs 16. It will be noted from fig. 2 that the width of the tabs 18 is such that they are taken up loosely between two neighboring tabs 16 and that the extensions 24 and 26 rest against the bottoms 23 of the tracks 22.

Hver av labbene 16 er dessuten forsynt med en oppadrettet flens 27 ved sin øvre ende, som ligger i avstand utenfor side- Each of the legs 16 is also provided with an upwardly directed flange 27 at its upper end, which is spaced outside the side

veggen, av hylsteret 10 og som ved sin in- the wall, of the casing 10 and which at its in-

nerflate er forsynt med et halvsirkulært horisontalt spor 28. Det vil bemerkes at sporet 28 vender mot sideveggen i hylste- nerve surface is provided with a semi-circular horizontal groove 28. It will be noted that the groove 28 faces the side wall of the sleeve

En kabel eller lås 34 er tredd gjennom den ringpassasje som dannes av sporene 28 og 30 og låser derved sammen parene av labber A cable or lock 34 is threaded through the annular passage formed by the grooves 28 and 30 and thereby locks together the pairs of legs

16 og 18. Denne kabel kan forløpe konti-nuerlig rundt hylsteromkretsen eller kan dannes av kortere seksjoner. For å gjøre det mulig å innføre kabelen i den passasje som dannes av sporene 28 og 30 er minst en labb 18, eller fortrinsvis tre eller fire labber på adskiltliggende steder rundt hyls- 16 and 18. This cable can run continuously around the casing circumference or can be formed by shorter sections. In order to make it possible to introduce the cable into the passage formed by the grooves 28 and 30, at least one lug 18, or preferably three or four lugs in spaced locations around the sleeve
