The purpose of Draft NUREG-1935 is to report a pilot study of best estimate analyses of the offsite radiological health consequences for potential severe reactor accidents for the Peach Bottom Atomic Power Station and the Surry Power Station.

To facilitate public review of this report, the following associated contractor reports are also now available to the public: NUREG/CR-7110, “SOARCA Project, Volume 1: Peach Bottom Integrated Analysis”; and NUREG/CR-7110, “SOARCA Project, Volume 2: Surry Integrated Analysis.” Additionally, NUREG/BR-0359, “Modeling Potential Reactor Accident Consequences,” a plain language public information brochure about the SOARCA project, is now available.

The SOARCA project analyzed a select set of potential severe reactor accidents at the Surry Power Station near Surry, VA and the Peach Bottom Atomic Power Station near Lancaster, PA. The project, which began in 2007, combined up-to-date information about the plants' layout and operations with local population data and emergency preparedness plans. This information was then analyzed using state-of-the-art computer codes that incorporate decades of international research into severe reactor accidents.
