Net Value = (APE + AOC + AOE + AOSC) - COE, where APE = averted public exposure costs AOC = averted offsite property damage costs AOE = averted occupational exposure costs AOSC = averted onsite costs averted cleanup and decontamination costs (ACC) + averted replacement power costs (ARPC)

COE- cost of enhancement Cost Significance NUREG/BR- Related Parameters Value If All Internally-Initiated Core Factor 0184 Section Damage Events at Pilgrim Are Eliminated APE Offsite exposure 5.7.1 AP-Rem (from MACCS2) $314K AOC Offsite economic 5.7.5 AOffsite Economic Cost Risk - OECR (from MACCS2) $566K From 12/12/2006 Entergy letter, Attachment C, Table E. 1-15:
