How many Magnox reactors are there?
The Magnox reactor is gas cooled (CO2) with graphite moderators. The fuel is natural uranium in metallic form, canned with a magnesium alloy called “Magnox”. The first Magnox station (Calder Hall) started operation in 1956, and over the next 15 years 10 additional stations comprising 22 reactor units started operation.
Are Magnox reactors safe?
The Magnox reactors were considered at the time to have a considerable degree of inherent safety because of their simple design, low power density, and gas coolant. Because of this they were not provided with secondary containment features.
What is Magnox used for?
Magnox is an alloy—mainly of magnesium with small amounts of aluminium and other metals—used in cladding unenriched uranium metal fuel with a non-oxidising covering to contain fission products in nuclear reactors.

How much does a pebble bed reactor cost?
The cost of China’s smaller modular pebble bed nuclear reactors should only be $420 million for a 210 MW version and $1.2 billion for a threepack that could be a dropin replacement for the coal burner at China’s many coal plants. The US has seen prices for US 1.2 GW AP1000 nuclear plants is far higher.
