Creative Engineering Dramatically Reduces Reactor Outage Time at OKG AVEVA Everything3D, combined with laser scanning and innovative prefabrication methods, increases plant availability and profitability. Oskarshamns Nuclear Power Plant, OKG, a company in the E.ON group, owns and operates three boiling water reactors, Oskarshamn 1, 2 and 3, often referred to as O1, O2 and O3. The nuclear power plant is located on the Swedish east coast, 30km north of Oskarshamn. The three reactors, with a net capacity of 2,511 MW, produce 10% of Sweden's electricity and went into commercial operation between 1972 and 1985. OKG needs to invest constantly in safety and modernisation in order to ensure that the plants can continue to operate for their planned 60-year lifetime. A day-long outage of a reactor would cost an estimated 1 million EUR in production losses; it is therefore of utmost importance to the profitability of the facility to keep outage time as short as possible. By using 3D modelling combined with laser scanning, and further developing prefabrication methods, OKG is expecting to dramatically reduce the outage time for the next modernisation project for O3, scheduled for June 2014. To find out more about the role AVEVA Everything3D™ (AVEVA E3D™) plays in this project, AVEVA visited OKG in November 2013, meeting Claes-Göran Wörmke, Project Manager, and Project Leader for the O3 modernisation project, and Peter Karlsson, Part-project Leader for electrical design, ONE Nordic. Safety first OKG's aim is that the reactors should operate at the highest possible safety level for at least 60 years, and each reactor is shut down every year for three to six weeks for maintenance, safety system control and replacement of 20% of the fuel elements. These planned outages normally occur between May and September. When AVEVA visited OKG, the O2 plant had been shut down for a huge, complex modernisation project to upgrade the turbine plant, installing many heavy items of equipment and involving demanding installation activities for vital safety systems.
