Tech/Engineering - Nuclear Eng/Sci / Reactor chemistry
French term or phrase: chaussette
This appears in a report on reactor chemistry.

La concentration en lithium a été compensée par calcul et corrigée par rapport à la **chaussette** de la spécification B-Li, en modélisant si nécessaire des appoints en LiOH ou des passages sur résine cationique.

I can't work out what's meant by "chaussette" here; I know it can mean sleeve or thimble in the case of control rods, but I don't think that applies here. I want to interpret it as "range" but I've never seen chaussette used in this way before and would appreciate some other opinions.

Many thanks.

Its also used to house instruments, so the adjustment is made by comparing the value at the instrument thimble as described in the B-Li specification.

As I recall, its also occasionally called a "well", but I couldn't find a reference to this, just going from memory.

I answered in the discussion but it didn't show up, so here goes again...

Check out the document http://www.epr-reactor.co.uk/ssmod/liblocal/docs/V3/Volume 3... abd search for the word "thimble".

According to this document, EDF France uses the term "thimble" to mean the boron-lithium ratio. If this applies, then you would be correct - the term would be "ratio". In this case its probably a derivative of the instrument used to measure it.

Many thanks John - really useful reference material - and to Caroline too. I'm being badgered by the system to close so I will - but I'll try and come back later to update the glossary entry when I've spoken to my client at the end of the (very long) job.

Notes to answerer
Asker: That's brilliant detective work, John - a very useful reference document! Many thanks. I'll check back with the client whether they'd rather I used thimble or ratio, but it's all much clearer now.
