Nuclear Indicators

NSr1: UNPLANNED AUTOMATIC SHUTDOWNS FOR EVERY 7000 h (WANO UA7)Note (1)

Graph showing IBERDROLA joint value calculated on the WANO UA7 (24 months) indicators of nuclear power plants weighted by IBERDROLA share power and ownership: 0.97 in 2008; 0.66 in 2009; 0.38 in 2010; 0.35 in 2011; 0.38 in 2012; 0.54 in 2013; 0.51 in 2014. .

Increment of unplanned automatic shutdowns is due mainly to Almaraz 1 because of manufacturing  deficiencies in a main component of power shaft replaced during the last refueling outage. 

NSr2: NUMBER OF NOTIFIED EVENTS BY TYPE ACCORDING INES SCALENote (2)

Graph showing IBERDROLA joint value calculated on the events notified by the nuclear power plant weighted by IBERDROLA share power and ownership: 6.7 LO, 0.1 L1, 0 L2 in 2008; 7.8 LO, 0.3 L1, 0 L2 in 2009; 6.2 LO, 0.4 L1, 0 L2 in 2010; 7.3 LO, 0.2 L1, 0 L2 in 2011; 4.7 LO, 0.1 L1, 0 L2 in 2012; 5.7 L0, 0 L1 0 L2 in 2013; 4.4 L0, 4.4 L1 0.1 L2 in 2014.

Annual values depend much on the number of refueling outages within the year and are subjected to normal statistical fluctuations.

 

NSr3: EFFECTIVE DOSE FOR CRITICAL GROUP (Public)(μSv)Note (3)

Graph showing Max. and Min. Values for IBERDROLA nuclear fleet for the Effective Dose for the Critical Group: 7.50 max. and 0.67 min. in 2008; 3.55 max. and 1.47 min in 2009; 1.94 max. and 0.28 min in 2010; 2.27 max. and 0.95 min. in 2011; 4.00 max. and 0.98 min. in 2012; 2.33 max. and 0.10 min. in 2013; 8.04 max. and 0.05 min. in 2014.

Actual annual values are very small fractions of the legal limits (between mills and ten-thousandths) and depend on the number of refueling outages within the year.

NSr3: COLLECTIVE DOSE (WANO CRE) (Workers) Sv-PersonNote (4)

Graph showing IBERDOLA joint value calculated on the WANO indicators of Nuclear CRE weighted share of power and property and considering its fuel cycle: 1.68 in 2008; 1.19 in 2009; 0.90 in 2010; 1.01 in 2011; 0.82 in 2012; 0.71 in 2013; 0.70 in 2014.

Variations of this indicator depend on the number and length of refueling outages within the year. Actions continue to be taken to optimize the collective dose.

 

NWr1: GENERATED AND CONDITIONED WASTE OF LOW AND MEDIUM ACTIVITY (m3)Note (5)

Graph showing IBERDROLA joint value calculated on the amount of generated waste of low and medium activity and packed in each plant weighted by IBERDROLA share power and ownership: 109.17 in 2008; 124.12 in 2009; 108.52 in 2010, 109.17 in 2011, 117.75 in 2012; 115.80 in 2013; 84.09 in 2014.

Annual values depend on the number of refueling outages within the year and are subjected to normal statistical fluctuations.

NWr2: CUMULATIVE SPENT FUEL (tU INITIAL)Note (6)

Graph showing IBERDROLA joint value calculated on the amount of initial U of each element in the fuel pool at each plant weighted by IBERDROLA share power and ownership: 488 in 2008; 519 in 2009; 528 in 2010; 556 in 2011; 576 in 2012; 596 in 2013; 609 in 2014.

Cumulative value obviously increases every year and annual value fluctuates annualy because depend much on the number of refueling outages within the year. 

 

NWr2: ANNUAL SPENT FUEL (tU INITIAL)Note (7)

Graph showing IBERDROLA joint value calculated on the amount of initial U of each element discharged annualy in the fuel pool at each plant weighted by IBERDROLA share power and ownership: 8 in 2008; 31 in 2009; 9 in 2010, 27 in 2011, 19 in 2012, 21 in 2013; 13 in 2014.

Cumulative value obviously increases every year and annual value fluctuates because it depends much on the number of refueling outages within the year. 

NWr3: AMOUNT OF DECOMMISSIONING WASTE (t)Note (8)

Graph showing currently there's no IBERDROLA Nuclear Power Plants in decommissioning: 2.031 in 2008; 2.031 in 2009; 2.031 in 2010; 2.031 in 2011; 2.031 in 2012; 2.031 in 2013; 2.031 in 2014.

Footnotes:

  • Note (1) IBERDROLA joint value calculated on the WANO UA7 (24 months) indicators of nuclear power plants weighted by IBERDROLA share power and ownership. Indicator does not take into account the Sta. Mª de Garoña NPP which was not included on WANO indicators during 2013. 
  • Note (2) IBERDROLA joint value calculated on the events notified by nuclear power plants weighted by IBERDROLA share power and ownership. Notified events according to the Safety Instruction IS-10 of the Nuclear Safety Council.
  • Note (3) Max. and Min. Values for IBERDROLA nuclear fleet for the Effective Dose for the Critical Group.Year value corresponds to the accumulated one until December (12 consecutive months). Each value is calculated taking into account actual releases and the impact of these over an ideal individual with the worst conditions in terms of exposure pathways (the sum of the worst case for every pathway), which represents very conservatively to the most exposed individual of the local community. Unit I and unit II of Almaraz are considered separately since 2013 to increase the accuracy of the indicator. This consideration modify retrospectively the indicator.
  • Note (4) IBERDROLA joint value calculated on the WANO CRE indicators of nuclear power plants weighted by IBERDROLA share power and ownership and considering its fuel cycle. Indicator does not take into account the Sta. Mª de Garoña NPP which was not included on WANO indicators during 2013. 
  • Note (5) IBERDROLA joint value calculated on the amount of generated waste of low and medium activity and packed in each plant weighted by IBERDROLA share power and ownership.
  • Note (6) IBERDROLA joint value calculated on the amount of initial U of each element in the fuel pool at each plant weighted by IBERDROLA share power and ownership. 
  • Note (7) IBERDROLA joint value calculated on the amount of initial U of each element discharged annually in the fuel pool at each plant weighted by IBERDROLA share power and ownership.
  • Note (8) Spent Fuel from Maine Yankee, Yankee Rowe and Connecticut Yankee is considered in this indicator. These spent fuel elements are stored in one ISFSI  per site, waiting for USA Federal Government to remove it.
