French term
puits de cuve
French to English
Tech/Engineering

This is in a document on a nuclear plant:
système de noyage du puits de cuve permettant la rétention du corium
Un système de circulation d’eau dans le puits de cuve refroidit l’extérieur de la cuve et provoque le gel du corium et son refroidissement.

reactor pit
A primary system for cooling the reactor; a reactor pit.

: I think the coolant would be in the vessel, not the pit. FRAM may use the term, but not for the coolant container. The pit also has folks walking around in the sunshine. http://www.reuters.com/article/us-japan-quake-idUSTRE72A0SS2...

: This is an official term used by FRAM; however, I am not an expert in this field, so I bow to the arguments of those who are.

reactor vessel
The pit is an excavation, like a cellar or sump, that holds the vessel, which in turn holds circulating coolant and other systems as well as the fuel. I haven't looked at the ProZ glossary but I think the corium coolant would have to be in the vessel.

: This is not how the nuclear technology works; the context clearly says that this coolant makes it possible to cool the OUTSIDE of the 'cuve' (= 'vessel'); "I think" here is a dangerous game.

The pit is the concrete sump. The coolant is outside the core (core therefore has to be the meaning of cuve in this case) but inside the vessel. Or else hit the alarm and run. http://www.livescience.com/13230-infographic-japan-nuclear-r...

: Core is the English equivalent of ”cœur du réacteur nucléaire”. For more info, see http://www.sfen.org/fr/lenergie-nucleaire/le-fonctionnement-...

Yes, your link shows that the fuel and coolant are in what your author and I call the core. The core is in what I call the vessel.

reactor cavity
The cavity is outside, not inside the reactor. It's purpose is to be an intermediary environment that protects the outside environment from the heat and radiation of the reactor. One of the ways is to flood the cavity with a coolant, as in these cases: http://www.sciencedirect.com/science/article/pii/S0029549313... http://www.sciencedirect.com/science/article/pii/S0951832097... ; https://www.google.com/patents/US5825838.

I might have misrepresented the cavity's purpose. You can read about it on Wikipedia: https://en.wikipedia.org/wiki/LFCM > "Reactor vessel breaching"

A better explanation was prompted by the discussion above: 'Hi [mrrafe], I did mean to give you credit for this diagram: http://www.livescience.com/13230-infographic-japan-nuclear-r... The reactor cavity that I am talking about is the space between the "reactor vessel" and "steel containment vessel," the space in which the pipes filled with moving coolant are located. These diagrams show this: http://www.sciencedirect.com/science/article/pii/S0029549313... In an emergency, the coolant from the pipes can be used to flood the reactor cavity. Under normal conditions, the "reactor cavity cooling system" is used to cool down this space: http://nuclear-research.tamu.edu/thermal-hydraulic-research-... I agree with you that "reactor pit" could be mistaken for the hole in the ground where the whole reactor system is located. The only instance in an online search that I found where they might be using "reactor pit" to mean "reactor cavity" is a temperature measurement project description: https://www.osti.gov/scitech/biblio/4115467-temperature-meas...

: Agreed that the core is in (what I would call) the cavity and both can contain coolant in a noncatastrophic emergency shutdown. /// Not worried about nuclear, just worried that ProZ won't pay me for my answer. { :-(

I would, however, just like to underline one point I've already made: this use of 'pit' is not just some arbitrary consensus of non-expert translators — it is also the official term approved by the FR PWR manufacturer FRAM.
That said, of course, it is sadly not unheard of for such companies to also "get it wrong" :-(
