Sizewell B Atkins has been involved in Sizewell B from its construction to the present day. During construction we provided structural services to assess the temporary loading and stress arrangements for the construction of the secondary containment dome.

We are currently assisting EDF Energy with the definition stages of the development of a new Dry Fuel Store, including establishing a suitable export route and investigating the capacity of the on-site fuel handling system.

.

NucleargenerationAtkins is a tier 1 strategic partner to EDF Energy for the supply of engineering, safety and environmental services to maintain their existing fleet of AGRs and PWR.

Atkins is one of the four lead partners to EDF 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 Boiler Closure Units • Programme management services• Japan earthquake recovery

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 EDF 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.

Seismic Modelling of an Advanced Gas Cooled (AGR) Nuclear Reactor Core – EDF 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 components change shape and the graphite bricks can become cracked. Atkins is currently investigating the implications of a seismic event on a graphite core containing varying levels of degradation using non-linear transient FE analysis.

A stick and spring “GCore” FE model of a half core has been created by Atkins in LS DYNA. The model simulates the graphite core under seismic loads and outputs the displacement of the graphite bricks and the loads on the keying and restraints system under these conditions so that the ability of the core to fulfil its functional requirements can be assessed.

Atkins first started working with the client on the GCore project over 10 years ago and in that time have developed a sophisticated model for Hinkley Point B / Hunterston B station cores. This was followed by a Hartlepool / Heysham 1 model with a Heysham 2 / Torness model scheduled to be built in 2012. The results obtained from this work provide key Safety Case references which allow continued safe generation of the AGR fleet.

As a result of the success of the GCore project, Atkins has initiated and is continuing to work with EDF Energy and Glasgow and Durham Universities on the development of an advanced computational code. The intention is to provide more opportunities for modelling the graphite core to a greater level of detail, while increasing computational efficiency.

Atkins is also involved in a project with EDF Energy and Bristol University which devises a programme of tests to be performed using a shaker table; scaled models of the graphite core are to be placed on the shaker table and subjected to a number of loading scenarios including a seismic event. Amongst other results, this programme of experiments will allow validation of the seismic assessment methodology.

The results from the above projects will provide valuable data which will be considered in EDF Energy’s forthcoming Plant Life Extension (PLEX) decision for their AGR fleet.
