In response to the Commission questions on this matter, CNSC staff noted that the proposed future decommissioning of the BHWP [Bruce Heavy Water Plant] is a different project from the proposed interim maintenance of the site in a shutdown state. The BHWP ceased production in 1997 and has since remained in a safe shutdown condition. 1, record 1, English, - shutdown%20state

The Bruce Heavy Water Plant consists of two enriching units and one finishing unit. Each enriching unit consists of three stages of enrichment to concentrate the deuterium from 0. 14% to 30% at a rate of 1344 kg/hr(2964 lbs/hr).(...) Should the enriching units product concentration be as low as 30%, the finishing unit will be capable to effect the necessary concentration up to 99. 75%. 2, record 7, English, - heavy%20water%20concentration%20unit
Record number: 7, Textual support number: 2 OBS
Preparation: In the preparation of [deuterium oxide] from natural water, advantage is taken of the differences in physical and chemical properties of the different isotopic species. (...) A method more suitable for natural water is one involving distillation. Since HDO and [deuterium oxide] have lower vapor pressures than [water], they can be separated from [water] by distillation. (...) Water distillation was used in three manhattan District heavy water plants, in which deuterium was concentrated from 0.0143 at % to about 90 at %. 3, record 7, English, - heavy%20water%20concentration%20unit

Concentration (en chimie): Ce terme peut avoir en chimie 2 significations. Il exprime la quantité par unité de volume de chacun des constituants présent dans un mélange, ou désigne l'opération qui aboutit à enrichir en l'un de ses constituants. (...) Lorsqu'un mélange, solide, liquide ou gazeux, contient plusieurs composants, l'enrichissement du milieu en un de ces composants prend également le nom de concentration. A partir d'un mélange liquide eau-sucre, on peut réaliser la concentration en sucre par évaporation de l'eau jusqu'à ce que le sucre, lorsque la solution est saturée, se sépare par cristallisation. 2, record 7, French, - Unit%C3%A9%20de%20concentration%20d%27eau%20lourde

Deutérium (préparation): On peut préparer le deutérium (...) directement par distillation de l'hydrogène liquide. (...) l'équilibre (...) ne se réalisant pas spontanément à la température de distillation, le produit, concentré en HD, doit être réchauffé passé sur catalyseur et refroidi avant d'être introduit dans la section finale de concentration. 2, record 7, French, - Unit%C3%A9%20de%20concentration%20d%27eau%20lourde
