This study, authorized by the Washington Public Power Supply System, was made to identify suitable additional future sites for nuclear power generating facilities with a 3000 megawatt capacity in the state of Washington and parts of Oregon and Idaho. A series of screening models was used to identify nine specific sites for evaluation. A decision analysis was conducted to evaluate these candidate sites. Six major objectives concerning human health and safety, environmental effects, socio-economic impacts, and financial considerations were formally utilized over the six attributes measuring the degree to which the objectives were met. Possible impacts at each site were assessed for each attribute by experts knowledgeable about the aspects in question. Evaluation and sensitivity analyses led to the recommendation that site specific studies should be conducted at three sites to select one for proceeding to the formal licensing process
