Table 1 contains technical data for the newer plants of the Magnox and AGR type. These are operated in the United Kingdom by Nuclear Electric pic. The electrical power output of the AGR is almost three times that of the Magnox, whereas its core volume is less than half as large. 

The Magnox reactor concept owes its origins to a design study conducted at Harwell, U.K., diuing the early 1950s. The reactor was designed with the dual role of plutonium and power production, and was known by the code word PIPPA... 

By the end of 1952 it was eertain that a PIPPA design had been produeed whieh eould and should be built. A summary report was prepared in January 1953, and soon after approval was granted for eonstmetion of the first two Magnox reaetors at Calder HaU. Before the first reaetor went eritieal in 1956 work had started on a further two reaetors at Calder Hall, and all four were at power in 1959. Constraetion at Chapeleross, in the southwest of Seotland, began in 1955. The fist... 

The large physical size of the later Magnox stations, such as Wylfa, led to the development of the more compact advanced gas-cooled reactor (AGR) design [31] that could utilize the standard turbine generator units available in the UK, Stainless-steel clad, enriched uranium oxide fuel can tolerate higher temperatures...

Cladding. The Magnox reactors get their name from the magnesium-aluminium alloy used to clad the fuel elements, and stainless steels are used in other gas-cooled reactors. In water reactors zirconium alloys are the favoured cladding materials.
