British Energy Group plc 
Boiler Closure Unit ("BCU") Update - Heysham 1 Reactor 1 return to service 
 
 
Further to its announcement on 26 January 2009, British Energy Group plc ("the 
Company") is pleased to announce that Heysham 1 Reactor 1 has synchronised to 
the National Grid, having made engineering modifications and received the 
necessary consent from the Nuclear Installations Inspectorate ("NII") to return 
the unit to service.  The unit has been out of service for an extended period of 
time and therefore a comprehensive return to service programme will be followed 
over the coming days. 
 
 
Following completion of the engineering modification work and upon receipt of 
the necessary regulatory clearance, the Company expects to return Reactor 2 at 
Hartlepool power station and Reactor 2 at Heysham 1 power station to service in 
a phased process over the coming weeks.

Notes to editors 
 
 
BCUs are unique to Hartlepool and Heysham 1 power stations. There are eight BCUs 
on each reactor which form part of the reactor pressure boundary. Each BCU is 
pre-stressed with nine layers of wire windings, wound around its outer 
periphery. 
 
 
Following the discovery of a broken wire during planned inspections of the BCUs 
in October 2007, the units at Hartlepool and Heysham 1 power stations were taken 
out of service. A detailed inspection programme has been undertaken to confirm 
the condition of the BCUs, and engineering modifications developed to address 
the issue. 
 
 
On 26 January 2009, the Company announced that Hartlepool Reactor 1 had 
synchronised to the National Grid.
