3. Innovation steps in fuel application

4. Impacts on fuel cost

5. Fuel cycle cost vs energy production
Actual trend : more production even
with higher fuel cost

6. Outages : february, may, august, november
Last innovation : 15 month cycle
Not only fuel and energy , but :
work organization
Outages : february, may, august, november

7. 15 m cycle in Paks 5 x 12 = 4 x 15 0. 1. 2. 3. 4. 5.

During 5 year :
4 outages
> 2% more yearly production
reduced maintenance cost
equal annual production and maintanance capacity need

8. Transition to 15m cycles
