Situation in the power plant



History

To handle the fuel assembly in the PWR reactors (Pressurised Water Reactor) around the world, we currently use the PMC system (fuel handling and storage system) :

- 1 Fuel Handling (Crane) - 1 Fuel Transfer Machine - 1 Fuel Manipulator

History

In 2001, EDF decided to install a new system.

These improvements were : - To increase safety (by putting new sensors) - To handle 8 fuel assemblies per hour (Today it is 5/h. => save 14h/activity => 28h/outage) - To reduce the cost of the service (Confidential)




Objectives for EDF

EDF has decided to install « The Supervisor » in the PMC system between 2005 – 2012, in order to

make these improvements.

This new system will be used in 1300 MW nuclear

power plants in France(20 units) and perhaps in

the EPR units.

Install new system in 1 power plant test(PALUEL=2 units)

2001

EDF decided to install this new system in all 1300 MW power plants in France

Figures : Study

Affair • 3 people in the engineer unit (Marseille) studied these improvements (Mechanic, electric, automatic data processing)

• 10 people participated in the study (like me) and elaborated the schedule condition (Studies on nuclear pressure : Risk of fire, of seism, redundancy).

Time 2 years

Cost Confidential





Figures : Installation

Units 20/58 units in France (1300 MW)

Firms REEL : For mechanic and electric improvements

SCHNEIDER ELECTRIC : For automatic data processing

Time 15 weeks :•12 weeks before the outage (outside the reactor building)•Use the old and part of the new system to remove fuel•3 weeks during the outage (In the reactor building)•Put fuel assembly with the new system

Waste 4t nuclear waste per unit

(4tx20=80t for French nuclear plants)

Cost Confidential





Figures : Operation

Preparation 1 person for 2 reactors for 1 month to create new procedures (20x2=10 people for French nuclear plants)

Training Training 35 people for every 2 reactors (=>35x20/2=350 people for French nuclear plants) for 1 week in Lyon

Cost Confidential





Figures : Maintenance

Preparation • Electrical and automatic service :

2 people per plant for 1 month to create new procedures (2x8=16 for French nuclear plants)

• Mechanic service :

1 person per plant for 1 month to create new procedures (1x8=8 for French nuclear plants)

Equipment Replace spare parts warehouse for French nuclear plants (Paris)

Firms 2 firms to do the maintenance for the French nuclear plants

Cost Confidential




Conclusion

5. Conclusion

To improve availability, safety, service and cost, EDF decided to install a new system to change nuclear fuel. To do this, in 20 units (1300MW) of nuclear plants and for 350 operators, we need : - 12 years - 47 EDF people to do the study - 2 firms to do the project

This investment by EDF is a part of the sustainable development for nuclear energy
