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.

Claire

Explanation:
Check out Termium:

"In a nuclear reactor a closure tube at the end of a ... rod. "

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.
