Our Nuclear Business - Nuclear Generation

Nuclear Generation

Atkins is a tier 1 strategic partner to British

Energy for the supply of engineering, safety and

environmental services to maintain their existing

fleet of AGR’s and PWR.

Atkins is one of the four lead partners to British Energy on the

Technical Support Alliance. Under this vehicle, Atkins has provided

more than 350 man years of support to the nuclear fleet in the last

three years alone, with key contributions in the areas of:

• Graphite Core programme in support of life extension

• Fuel Route improvement programme

• Periodic Safety Review programme

• Key recovery projects such as the Boilers and Boiler Closure

Units (BCU)

Case Study

Boiler Closure Units

Inspections of the Boiler Closure Units (BCU) during a Hartlepool

outage identified a number of significant defects in the pre-stressing

wire winding system over several BCUs. These were considered to

significantly undermine the safety case for continued operation as a

result of which, Heysham 1 and Hartlepool were closed down and

British Energy mobilised a project team to engineer, procure and

install solutions to allow the stations to be repowered.

Atkins provided a team of up to 50 people to support this project

and provided the solution to return the reactors back to service by

designing a circumferential steel band to lock in the existing

pre-stress in the wire windings. Nine of these bands were fitted to

each BCU to provide frictional restraint of the wires underneath

effectively acting as an additional layer of passive wire winding.

Atkins also designed an environmental control system to protect the

wires and bands from corrosion, a modification to the existing BCU

cooling system, and the fitting of a thermal shield to replace the

original fillite insulation that was removed to install the bands.

Case Study

Seismic Modelling of an AGR Nuclear Reactor

Core - British Energy

The core of an AGR consists of stacks of graphite bricks providing

vertical channels for fuel assemblies, control rods and coolant

flow. These bricks are stacked and interconnected by a system

of keys and keyways allowing the core to expand and contract

thermally whilst retaining its cylindrical shape. As the reactor

ages the graphite core can become cracked. Atkins is currently

investigating the seismic implications of graphite cracking via

FE analysis.

An FE model of each graphite brick has been created in

LS-DYNA. The model simulates the graphite core under seismic

loads and outputs loads and displacement of the graphite bricks

under seismic conditions so that the control rod insertion path

alignment can be assessed.
