2 Nuclear Power Plants in Finland in 2008 Olkiluoto OL1 BWR 860 MW 1978 OL2 BWR 860 MW 1980 Population 5.2 million Power Demand 90 TWh/a Loviisa LO1 PWR 488 MW 1977 LO2 PWR 488 MW 1979 Olkiluoto Loviisa Helsinki Ilkka Mikkola 2

3 Teollisuuden Voima Oyj (TVO) Company Privately owned generating company Sells electricity only to the shareholders at cost basis, to industry like UPM, and cities/towns like Helsinki Existing Nuclear Power Plant Units (Olkiluoto 1 and 2) 2 x 860 MW, BWR, Westinghouse Atom Commercial operation 1979 and 1982 Modernization and upgrade in several stages from 660 to 860 MW New Nuclear Power Plant Unit (Olkiluoto 3) 1 x 1,600 MW, PWR, Framatome-Siemens consortium Start of operation in 2012 Subsidiaries Posiva Oy (60%), responsible for the final disposal of spent fuel produced by its shareholders TVO Nuclear Services Oy (100%), specialized in know-how consulting Ilkka Mikkola 3

4 TVO - Leading Nuclear Power Generator in Finland, Covering about one fifth of Energy Supply in Finland - strict safety culture: safety never Inga kompromisser med säkerhet compromised - highly valued company worldwide En aksepterad och respekterad firma - advanced and modern plant units Moderna anläggningar, världsklass, with excellent track records Lastfaktor över 90% under 20 år - competitive and widely accepted Bra lösning för kärnkraftens avfall nucl. waste management concept 4 16 December 2008 Mikael Solala

5 OL1/OL2 - Power Capacity; (2011: 890 MW, : 980 MW) MWe st Low Pressure Turbine Retrofit +35 MWe 1 st Reactor Thermal Output Increase nd Low Pressure Turbine Retrofit + 30 MWe High Pressure Turbine Retrofit +20 MWe 2 nd Reactor Thermal Output Increase December rd Reactor Thermal Output Increase Mikael Solala

6 Fuel purchase from ore to nuclear fuel 40 tonnes of enriched U needed for OL1+OL2/a vs. 5 million tonnes of coal (en 300 meter lång båt, tonnes, varje vecka) - Uranium concentrate from Canada, Australia (co product of copper production), and also others, partly re-enriched tails; - and concentrates stored at convertors, e.g. in France, for the needs of even several years, cost of concentrate is small - ENRICHMENT done mostly in EU, at Urenco, additional quantities in Russia, U-235 content % about 3.5 % U FUEL MANUFACTURING is purchased from Sweden (Westinghouse) and Spain (GE Enusa), and for Olkiluoto 3 from Germany (AREVA) (for conversion UF 6 UO 2, fuel pellets rods assemblies) Ilkka Mikkola 6

7 Australian uranium concentrates in France (U stored for several years) Ilkka Mikkola 7

8 Implementation of Waste Management Teollisuuden Voima Oyj Fortum Power and Heat Oy In future Olkiluoto power plant Interim storage of spent nuclear fuel Interim storage of spent nuclear fuel Loviisa power plant Posiva Oy Operating waste repository Operating waste repository Final disposal of spent nuclear fuel 8 16 December 2008 Mikael Solala

13 Arguments for a New Nuclear Plant Unit Nuclear power together with available bio fuels reduces carbon dioxide emissions in electricity production Nuclear power reduces dependence on electricity import Nuclear power is competitive compared with other energy sources Nuclear power is suitable for covering the increasing electricity consumption in Finland Subsidies are not required for construction of nuclear power Acceptable waste solution exists December 2008 Mikael Solala

14 Electricity Supply by Sources in 2007: (Norway hydro, Sweden 50/50 hydro+nucl) Source: Finnish Energy Industries December 2008 Mikael Solala

15 Finland - Total Electricity Consumption Present growth: Replacing fuels with electricity Forecast TWh Statistics December 2008 Mikael Solala

16 Need for Electric Power and Production Capacity: for replacing imports from Russia, replacing coal Source: Finnish Energy Industries December 2008 Mikael Solala

17 Olkiluoto 3 Project in a Nutshell - Investment decision: Start up: Turn-key supplier: Consortium formed by AREVA NP and Siemens - Reactor type: EPR (PWR) - Reactor thermal power: 4,300 MW - Net electrical output: 1,600 MW - Investment cost: 3 billion (in 2003 value) - Operating personnel: December 2008 Mikael Solala

18 OL3 - Status December Technical and safety requirements set for the OL3 plant unit will be met. - All major purchases made. - Reactor plant: emphasis on construction work; Turbine plant: heavy components are in Olkiluoto, installations take place. - Manpower at site about Civil construction works in two/three shifts. - Operating personnel recruited and in training. - Addition: Pressure vessel arrived in January December 2008 Mikael Solala 18

23 OL4 in a nutshell Electrical output MW Investment cost about 3-4 billion Euros Plant type either a boiling water reactor (BWR) or pressurized water reactor (PWR) plant All TVO s present shareholders support the venture Application for a decision-in-principle submitted to the Council of State on 25 April, 2008; public support over 50% Parliament decision on the application expected in 2010 Investment decision expected in 2012 On balance sheet financing Operation estimated to start by Ilkka Mikkola

24 OL4 Overall time schedule Environmental Impact Assessment (EIA) and decision-in-principle (DIP) Plant type selection Realization - Design and preparatory work - Civil construction and installations - Commissioning - Operation Ilkka Mikkola

25 Safety of OL3 and OL1&2 First about OL3 safety: December 2008 Mikael Solala

28 The safety system consists of four parallel trains, each capable of performing the required safeguard function on its own. (IM: samma gäller OL2 och OL2, många äldre verk tre parallella system) The four parallel trains are located in separate buildings on different sides of the reactor building to eliminate the possibilityof simultaneous failure. (samma med OL1-2)

29 Safety of OL1-2 upgraded Modernisation in : Upgrading safety systems, new fuel 9 x 9, lower fuel temperature, Replacement of a 2 km of piping, and component materials; SAM system: Severe Accident Mitigation (core melt taken into account etc. after TMI ), Turbine efficiency upgraded from 660 to 710 MWe. Modernisation in : Upgrading to 840 MWe, New fuel 10 x 10, reactor power upgrading, New safety and el. systems, generators, new LP turbines etc., Changes in : 860 MWe, automation upgrading, simulator changes, new HP turbine December 2008 Mikael Solala

30 Severe Accident Management in Olkiluoto 1 and 2 NPP Emergency Operating Procedure for severe accidents (full core melt) - Primary system depressurisation - Flooding of lower drywell - Containment water filling - Procedures for filtered containment venting - Instructions to recover active core and containment cooling systems

31 TVO wants to keep the plant always like a new plant. Probabilistic accident sequences analysis, learning from experience, treatment of uncertainties, importance ranking Refurbishment of the weak links of the chains when doing plant maintenance
