Following on from my previous question, I'm not quite sure what they mean by "bouchon" in this context:
"La dalle supérieure du caisson est caracterisée par une conception particulière: le BTS a été réalisé sur etaiement, puis un clavage annulaire l'a solidarisé avecle fut. La précontainte circulaire a ensuite été activée pour enserrer ce bouchon, de sorte que la tenue du BTS est assurée uniquement par la précontrainte circonférentielle du fut."

Comment: "Thanks Conor - I'm going to call it a plug because that's what it usally is in this nuclear context. But thanks to everyone else for explanations and support - much appeciated as ever."

stopper-like lid
The upper slab of the caission [tank?] has a special feature. The engineering work was done by shoring up the slab over the caisson then a ring [some kind of metal I suppose] was jammed around it so it would fit over the caisson. The prestressed, circular slab was then released to close down this stopper-like lid so that the slab is held in place solely by the prestressed circumference of the caisson.

clavage is the junction or coming together of the slab and the caisson..
correx: then a ring seal was used to fit the slab to the caisson.
clavage annualaire...I\'m saying ring seal but it means a ring [of metal? ] was used to seal the slab to the caisson..

a bouchon is a stopper or lid...I say stopper like lid..because the idea is a like a bottle and stopper...

French term (edited):
bouchon (in this context)
retainer
The retainer is a part that is put on the reinforcement. The retainer is then secured, thus fixing the prestressing force.

You might be right
The BTS sounds as if it might indeed be the "bouchon" = plug?
plug. Piece of absorbing material used to close the aperture of a channel through a reactor core or other source of ionizing radiation.
[Chambers Nuclear Energy and Radiation DIctionary]
AFNOR also uses "tampon" for "bouchon" (in some contexts).
The top slab of the reactor pressure vessel (though these can be made of concrete, I think it is the first time I have encountered such "first hand") appears to have been built with a hole in it, inside which the "bouchon" is subsequently cast atop falsework. The annular void between the "plug" and the surrounding "top slab" is grouted up (that's what they mean by "clavage", and the circular prestressing tendons (of the top slab/circular containment are then tensioned to "grip" the plug and prevent it falling once the falsework is removed.

Note too that the Framatome/AFNOR dict. also lists \"Bouchon de Tube de Structure\" (BTS) which it gives as \"thimble end plug\", which is part of the structure housing the gubbins for lowering fuel rods, etc., from what I can make out.

Discussion
Alex: Having finally tracked down your "thimble end plug" in the AFNOR glossary (WHY do they persist in ordering terms alphabetically including prepositions - catches me out every time!), I still think that a thimble end plug is a specific part of a fuel assembly rather than the reactor pressure vessel structure and surely the assemblies would have long since been removed by the time decommissioning is being carried out?
