Tel. 01728 633300

Sizewell A power station ceased generating electricity at the end of 2006. An Environmental Impact Assessment for Decommissioning (EIAD) was approved in 2006. Fuel will be removed from the reactors and sent to Sellafield for treatment.

Overview

Age Operated from 1966 - 2006
Site Stakeholder Group Sizewell A Site Stakeholder Group
Site Licensee Magnox Limited
Parent Body Organisation Energy Solutions Inc
Status Defuelling
Cost - Lifetime
(total discounted nuclear liability)
 £789m

 * The costs of discharging the nuclear liability will be incurred over a significant period of time. To take account of the time value of money, the costs are "discounted" back to a present value. Effectively this is the amount that would need to be invested today, at a set rate of interest (the discount rate) in order to pay for the liability in the future as it falls due.
