After benefiting from successful installations of High Density Polyethylene (HDPE) at Torness, Heysham 2 and Hinckley Point B, EDF British Energy has once again commissioned Boulting to upgrade the Reactor Cooling Water (RCW) system at a fourth power station.
Providing cooling water to safety related plant and equipment, the RCW system ensures that the nuclear plant operates both efficiently and safely. The current pipeline is subject to periodic problems due to failures of the existing Vylastic coating, including:
In the worst case scenario this causes flooding and system malfunction, which can eventually lead to an entire reactor shut down.
To avoid such scenarios, existing buried cast iron pipeline - running between the Turbine Hall and Cooling Water Pump house - will be replaced.
Work commenced on phase 1 on the 4th April 2011 and includes:
Following the completion of Phase 1 the proposal is to progress the design development to a level appropriate for approval by EDF British Energy.
This will require a slit trench to be dug in order to collect data for evaluating the risks of installation and substantiate the design.
