TSNP is a project owned by CGNPC (70%) and EDF (30%).

Enterprises from both China and France are in charge of design,

procurement and construction :

NI: AREVA in France takes the lead of NI supply and design

contracts, while CNPEC (China Guangdong Nuclear Power

Engineering Co., Ltd. ) and CNPDC (China Guangdong Nuclear

Power Design Co., Ltd. ) also take part in.

CI: ALSTOM in France and DEC (Dongfang Electric Co. Ltd.) in

China are responsible for TG design and supply contracts.

Other contracts are in the charge of some domestic enterprises.

CEPR - Civil Works - Concrete

HRA Raft example: One pour

Comprehensive method statement, main points:

– The C40/50 concrete mix,

– The global organization in order to avoid cold joint,

– The risk of delayed ettringite: in case in core temperature is

higher than 65 °C

Optimization of theC40/50 concrete mix: cement content, slag

and/or fly ash content, retarder admixture (minimize the heat of

hydration).

The mock-up tests to assess:

– The concrete placing organization

– The maximum in core temperature rise

Thorough preparation and follow-up

Importance of a good concrete curing (1 month).

EPR Civil Works are complex mainly due to :

Large concrete quantity,

Large pours > 9,000 m3 for buildings rafts and > 5,900 m3 for TG pedestal raft,

Specific concretes, inner containment, APC Shell, core catcher (sacrificial concretes),

High reinforcement density,

Numerous embedded elements,

Formworks : little space between APC shell and buildings walls and roofs

Heavy lifting :

Dome (~ 260t)

Precast elements for APC Shell roof (>120t),

Main Control Room (>170t),

CEPR Civil Works - Conclusion

Experience Feed Back facilitates the progress of Taishan construction.

However, construction optimization will benefit to new EPR projects.
