The Waste Behaviour HALES team, with particular expertise in the behaviour of nitric acid based Highly Active Liquor (HAL), is primarily based in the NNL Central Laboratory on the Sellafield site. The team which consists of predominantly chemists, undertakes a full range of work from desk-based studies to hands-on practical inactive laboratory ...

The Sellafield HASTs are of two fundamentally different designs, incorporating vastly different operating capacities, vessel shapes, cooling capability and agitation systems. There are small number of old-side HASTs which each have a relatively small working volume of HAL, cooling coils and no installed agitation systems. The

Highly Active Liquor Evaporation and Storage (HALES) is a department at Sellafield. It conditions nuclear waste streams from the Magnox and Thorp reprocessing plants, prior to transfer to the Waste Vitrification Plant.

2014年5月25日 · A key process area on the Sellafield site, the Highly Active Liquor Evaporation and Storage (HALES) plants are of fundamental importance. Continued operations remain a high priority for the site operator British Nuclear Group – a major customer for Nexia Solutions.

The HALES plant fulfils a central role at Sellafield as it processes the nitric acid based aqueous waste raffinates from both the Magnox and Thorp reprocessing plants, which contain the vast majority of the fission products from the spent fuel. The raffinates are concentrated in HA evaporators to a pre-defined end point, producing HAL which

The Highly Active Liquor Evaporation and Storage (HALES) facility at the Sellafield nuclear licensed site receives Highly Active (HA) raffinate from the THermal Oxide Reprocessing Plant (THORP) and Magnox reprocessing plant.

2014年5月25日 · One of our proudest achievements over the past few years has been the combined work we have carried out to support the ongoing operation of the evaporators in the HALES (Highly Active Liquor Evaporation and Storage) plant at Sellafield. The HALES plant is an essential part of reprocessing and therefore of key strategic importance to Sellafield ...

Highly active liquor (HAL) is produced at Sellafield from the evaporation of raffinates. The raffinates are a waste stream from the nuclear reprocessing plants and contain the fission...

2024年11月15日 · The purpose of this inspection was to enable ONR to form a view on the claims made within the safety case on the Evaporator Delta (Evap D) ventilation system under the control of the Highly Active Liquor Evaporation and Storage (HALES) and verify that the key equipment is available and maintained.

1997年9月9日 · Sellafield is home to the world's first industrial scale nuclear power station, Calder Hall. The four Calder Hall (CH) Magnox reactors, with a total output of 200 MW, entered service between ...
