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. In 1991 the Waste Vitrification Plant (WVP), which seals high-level radioactive waste in glass, was opened. In this plant, liquid wastes are mixed with glass and melted in a furnace,
Berkeley Nuclear Power Station and the site completely cleared between 2070 and 2080. In March 2012 five of the 310-tonne boilers were moved from the station to Sweden for decontamination and recycling. In December 2013 the Nuclear Decommissioning Authority selected Berkeley as the preferred interim store for Intermediate-level waste from the decommissioned Oldbury nuclear power station. This became operational in 2014. Berkeley is one of four nuclear power stations located close to the mouth of the River Severn and the Bristol Channel, the others being Oldbury, Hinkley Point A and Hinkley Point B.
