Paks NPP Four VVER-440/V213 units with 500 MW uprated power Started in : 1983, 1984, 1986 and 1987 Power up-rates in : 2007, 2008, 2009 and 2006 Planned operation till: 2033, 2034, 2036 and 2037 Share of total electricity production in Hungary: ~50 % Share of electricity consumption in Hungary: ~ 36 %

Innovation steps in fuel application

Impacts on fuel cost

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

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

15 m cycle in Paks 5 x 12 = 4 x 15 0. 1. 2. 3. 4. 5. 1,2,3,4 -,1,2,3 4,-,1,2 3,4,-,1 2,3,4,- 1,4,2,3 During 5 year : 4 outages > 2% more yearly production reduced maintenance cost equal annual production and maintanance capacity need

Transition to 15m cycles
