This study is an evaluation of a pressurized-water reactor PWR accident as defined by WASH 1400 for the proposed nuclear reactor site at Cementon, N. Y. Using an extension of the Environmental Protection Agencys AIREM computer code, the following were analyzed for up to 50 miles for 16 compass direction 1 whole body doses due to cloud submersion, inhalation and ground deposition and 2 thyroid, lung, and gastrointestinal tract doses due to inhalation. In addition, a model was developed to simulate population evacuation up to both 10 and 50 miles and again determine doses. Subsequently, the nuclide concentration in drinking water, milk, and fish in the area of interest is examined, as well as doses due to swimming in a nearby contaminated lake. Iodine 131 is the isotope of concern, being the major contributor to the inhalation dose which itself contributes 60 of the total dose received in this instance. Evacuation, a significant mode of dose reduction, is examined. An alternate plan of seeking shelter in the event of an accident is suggested because at close proximities to the site, the average winds would be expected to carry the radioactive cloud downwind much too quickly to permit successful evacuation.
