OKG

From Wikipedia, the free encyclopedia

OKG AB (Oskarshamns Kraftgrupp AB) is a Swedish corporation who owns and operates three nuclear power reactors at Simpevarp near Oskarshamn, Sweden. It is part of the E.ON group.

The three reactors, Oskarshamn 1-3, was manufactured by ASEA Atom and was put into operation in 1972, 1974, and 1985, respectively. At the reactor site, some 30 km north of Oskarshamn, OKG also operates CLAB – Sweden's central interim storage facility for radioactive waste. From 2006-10-01, however, CLAB will be transferred to SKB (Svensk Kärnbränslehantering AB or Swedish Nuclear Fuel and Waste Management Co).

[edit] Nuclear reactors

All three reactors are boiling water reactors (BWRs). As of 2006, the maximum output for Oskarshamn 1 and 2 is 495 MW (O1) and 625 MW (O2). The most recent reactor, O3, will be upgraded from 1,200 MW to 1,450 MW in 2008. OKG estimates that O1, O2, and O3 combined account for ten percent of the total electricity generation in Sweden.
