Question 2 What is the projected operating life of WPPSS 2? What is the projected cost 

 of decommissioning WTPSS 2 now. and what is the projected cost of 

 decommissioning WPPSS 2 at the end of its operating life? How much money 

 is currently in the sinking fund to pay for decommissioning of WPPSS 2? 



Question 2b: What are the projected costs of removal for WPPSS 1 & 3 in light of 

 Washington State reclamation standards to return the site to its original 



condition? 



Answer: WNP-2 is currently scheduled to operate until the expiration of its Operating 



License in the year 2024 However, the industry is planning on extending the 

 life of nuclear plants The Supply System is taking appropriate actions for that 

 option to be available 



The cost to decommission WNP-2 is approximately $373 million (1993 dollars), 

 whether it is decommissioned in 1993 or 2024 The estimate is based on 

 SAFESTOR (long-term storage before decommissioning) for 30 years prior to 

 radiological decontamination and site restoration Decommissioning WNP-2 in 

 1993 would require more ratepayer revenue than waiting until 2024, when 

 accumulated earnings on the sinking fund will pay a greater share of the costs. 

 The current sinking fund balance is approximately $19.2 million. 



The Supply System has estimated the cost of restoration of WNP-1 and 3 in the 

 Long Range Forecast of its FY 1994 Budget. If it is assumed that the sites must 

 be returned to their original condition, it would entail removal of all temporary 

 buildings and structures, burial of the reactor and related buildings, and 

 recontouring and revegetating the site. This is estimated at
