River Calder, Cumbria
The River Calder is a river in Cumbria, England.
The river rises at Lankrigg Moss and flows southwards for 10 miles (16 km) through an ancient landscape, flowing under Monks Bridge (a packhorse bridge) and by the site of Calder Abbey, as well as several tumuli and other mysterious monuments. It also runs past and (indirectly) gives its name to Calder Hall, site of the world's first commercial nuclear reactor.
Near its mouth the river runs through the Sellafield nuclear site in an artificially straightened section before flowing into the Irish Sea at the same point as the River Ehen, just southwest of Sellafield.

Thermal Oxide Reprocessing Plant
The Thermal Oxide Reprocessing Plant, or THORP, is a nuclear fuel reprocessing plant at Sellafield in Cumbria, England. THORP is owned by the Nuclear Decommissioning Authority and operated by Sellafield Ltd, the site licensee.
Spent nuclear fuel from nuclear reactors was reprocessed to separate the 96% uranium and the 1% plutonium from the 3% radioactive wastes, which are treated and stored at the plant. The uranium is then made available for customers to be manufactured into new fuel, and the plutonium incorporated into mixed oxide fuel.
On 14 November 2018 it was announced that reprocessing operations had ended at THORP after earning £9bn in revenue. The receipt and storage facility (which makes up nearly half of THORP's physical footprint), will operate through to the 2070s to receive and store spent nuclear fuel from the UK's PWR and AGR fleet. The decommissioning is expected to start around 2075.

Magnox Reprocessing Plant
The Magnox Reprocessing Plant is a former nuclear reprocessing facility at Sellafield in northern England, which operated from 1964 to 2022. The plant used PUREX chemistry (based on tributyl phosphate (TBP)) to extract plutonium and uranium from used nuclear fuel originating primarily from Magnox reactors. The plant was originally constructed and operated by the United Kingdom Atomic Energy Authority (UKAEA), but in 1971 control was transferred to British Nuclear Fuels Limited (BNFL). From 2005 the plant was operated by Sellafield Ltd.
