Nuclear Safety at the Heart of our Activities 1/2
In the aftermath of the earthquake and tsunami in Japan, AREVA is
involved in many actions aiming at increasing existing and future
reactors’ safety worldwide
AREVA team is supporting utilities in preparation for safety
reassessments of their nuclear power plants with the AREVA safety
alliance portfolio of solutions
IAEA December 12, 2011 – p.13
Nuclear Safety at the Heart of our Activities 2/2
EPR safety systems would have resisted the seismic
event and the tsunami
EPR is licensed to resist to a 0.25g-0.3g peak ground acceleration
Seismic Margin Assessments lead to a 95% probability that a 0.6g peak ground
acceleration wouldn’t have impacted EPR’s capabilities to mitigate the risk of severe accident
No deterioration of diesel nor safeguard buildings due to dynamic impact of wave
- Doors would have resisted to a 3-4m wave on the platform
No deterioration of diesel nor safeguard buildings due to temporary flooding
- Leak-tightness is ensured
In similar seismic conditions as of Fukushima earthquake,
the EPR wouldn’t have endured damages impairing the
adequate operation of its safety systems

IAEA December 12, 2011 – p.16
Time Schedule is a Plan, a Roadmap, a Communication Tool, a Contractual Document
Lead Time
IAEA December 12, 2011 – p.17
Time ManagementHow to build a schedule
1. Start from WBS (avoid missing scope), andWork Package deliverables.
2. Create activity list and identify the contractualmilestones.
3. Create network diagram.
4. Identify sequence & interfaces betweenactivities.
5. Allocate resources and estimate durations.
6. Define intermediate and internal milestones.
7. Identify critical path
8. Produce the schedule.
9. Identify risks and opportunities
10. Iterations - optimise the schedule.
11. Gain approval. Establish baseline.

WBS Work Breakdown Structure
WBS is the “backbone” of the project
Key Objective: Defining, Authorizing and Controlling the
Scope
IAEA December 12, 2011 – p.19
Standard WBS
The standard WBS for the Consortium and Nuclear Island
scope is broken down by disciplines and coded as follows:
CS = Consortium
NI0 = Project Management
NI1 = Engineering
NI2 = Procurement
NI3 = Erection
NI4 = Commissioning
