Kjeller is a village located near Lillestrøm in the municipality of Skedsmo, Norway. It is located 25 kilometers north-east of Oslo.

Historically, Kjeller has also been the location for a small aircraft factory. The Telenor Research Centre was located in Kjeller until 2001, when the majority of employees moved to Fornebu on 23 November. Akershus University College was opened in autumn 2003 at Telenor's previous location. Approximately 3700 students attend the university.

Nuclear reactor[edit]

The nuclear reactor at Kjeller, opened on November 28, 1951 was the first reactor outside the US, Soviet Union, Canada, Great Britain and France. It was a joint project by the Dutch and Norwegian governments. The Netherlands supplied the uranium and Norway the heavy water. The nuclear reactor is used in scientific research and is together with a nuclear reactor in Halden Norway's only two nuclear reactors. Neither of them is in commercial use.

On 9 September 2006, the reactor suffered a "contained" leak which forced it to shut down for three weeks for repairs.[1] [2] [3]

Its operating license expires at the end of 2018.[1]
