This report covers the radiation exposure history at Seabrook Station from entry into Cycle 7 power generation through the completion of Refueling Outage 7 (including the outage extension for repairs to Emergency Diesel Generator “B”). This encompasses the period May 14, 1999 through January 28, 2001. Total dose for Cycle 7 was 78.533 Person-rem, compared to a goal of 104.380. This is well below the 130.067 Person-rem total for Cycle 6.

Our 3-year average dose at the end of year 2000 was 65 Person-rem. This places us solidly in the Top Quartile (<79 person-rem) for US PWRs, and very close to the Top Decile (<60 Personrem).
