Magnox control rods

WebPrincipal control over the reaction rate was provided by a number (48 at Chapelcross and Calder Hall) boron-steel control rods which could be raised and lowered as required in vertical channels. At higher temperatures, aluminium is no longer structurally sound, which led to the development of the magnox alloy fuel cladding. The pre-stressed concrete pressure vessel contains the reactor core and the boilers. To minimise the number of penetrations into the vessel (and thus reduce the number of possible breach sites) the boilers are of the once through design where all boiling and superheating is carried out within the boiler tubes.
