London (Platts)--22May2008

New information about a security scare has forced the operator of the
2,311 MW Oskarshamn power station to take a unit offline Wednesday night,
operator OKG said Thursday.

The closure of the 491 MW unit, known as 01, will allow a "thorough
police search" to take place, OKG managing director Lars Thuring said in a
statement.

The measure follows the arrest yesterday of two welding contractors on
suspicion of planning to sabotage Oskarshamn.

One of the men was found with traces of the highly explosive TAPT in a
random search carried out early Wednesday morning.

OKG said that shutdown was activated when it emerged that the men had
been given access to certain areas of the O1 unit.

The men had been working on the O2 unit, which was already decommissioned
for maintenance.

"Nothing in our surveillance system suggests that they [the two men]
actually entered O1, but as an extra precaution we have chosen to take O1
offline," Thuring said.

He added that O2 would also be searched by police and that 03 would
remain online because the sabotage suspects did not have access to it.
"We take what has happened very seriously and we are doing everything,
together with police, to clear up the incident," Thuring said.

Oskarshamn comprises three units, 01 at 491 MW capacity, 02 at 623 MW and
03 at 1,197 MW.

The facility is 54.5% owned by OKG parent company E.ON Sverige, a
subsidiary of German utility giant E.ON, and 45.5% by Finnish energy major
Fortum.
