RPM Meeting , Essen Forsmark 1 Generator output net 968 MWe Critical reactor April 23, 1980 Commercial operation December 10, 1980 Forsmark 2 Generator output net 964 MWe Critical reactor November 16, 1980 Commercial operation July 7, 1981 Forsmark 3 Generator output net 1,185 MWe Critical reactor October 28, 1984 Commercial operation August 21, 1985 Forsmark NPP 3 BWR units - ABB design

RPM Meeting , Essen Forsmark 1 At start900 MW MW MW MW Forsmark 2 At start900 MW MW MW MW Forsmark 3 At start1 050 MW MW MW MW MW Power upgrades - Net electrical output

RPM Meeting , Essen Power upgrade F1 – year %  120% = +120 MW F2 – year %  120% = +120 MW F3 – year %  125% = +170 MW Altogether 410 MW (electric effect) Annual production raise = 3,3 TWh

RPM Meeting , Essen Radiological Analyses Performed Impact of the power upgrade on: Core inventory Source terms / Activity content Radiation protection (doses & dose rates) Releases to the environment

RPM Meeting , Essen Main Radiological Impacts Forward pumping of the high pressure turbine system drainage (F1 & F2, F3 is already operating this way) Replacement of steam dryers & steam separators Replacement of steam reheating system in turbine system (F1 & F2) New components  less maintenance & materials testing

RPM Meeting , Essen Measure Replacement Modification HP system Drainage: Forward Pumping Inner Isolation Valves Steam dryer Moderator Tank Lid Steam Separators HPRV High Pressure Turbine Moist Separator / Reheater Improved Scram system Feed Water Pumps: New Impellers Forsmark 1 RPM Meeting , Essen

ALARA Goal - Radiation Doses General –Total collective dose < 2,5 manSv (0,8 manSv / GWe) –At latest year 2011 < 2,0 manSv (ca 0,6 manSv / GWe) –Individual doses Planning < 10 mSv Reality Max 2 % > 10 mSv No one > 20 mSv Priority –FMEP = Foreign Materials Exclusion Program –Prevent fuel failures Year 2010 < 1 fuel failure / 10 year & unit –Replacement of Moisture Separators / Reheaters (F1 & F2)

RPM Meeting , Essen Effluents to the Environment - Total

RPM Meeting , Essen Effluents to the Environment - Water

RPM Meeting , Essen Release of C-14 & H-3 after upgrade

RPM Meeting , Essen Measures to lower the effluents Water Lower the water consumption F1 & F2 –Reuse of pool water –Storage tanks for intermediate storage Improved waste water evaporation system at F1 Air Avoid fuel failures!

RPM Meeting , Essen ALARA Goal - Effluents General –Individual dose < 0,0005 mSv (inkl C-14) –Individual dose from water releases In the long term (year 2015) in the order of magnitude 0, mSv (0,0001  Sv) Priority –Prevention of fuel failures –Lowered water releases from F1/F2 Improved evapuration capacity Lowered water consumtion

RPM Meeting , Essen Impact on Waste Increase of high level activity waste (fuel & control rods) by 2-3 ton/year Activity contents in ion exchange resins may be increased by 50% (due to forward pumping) Increased neutron induced activity in internal reactor components by 11% (F1/F2) respectively 14% (F3)
