The Compact Ignition Tokamak (CIT) is the proposed next step in the US magnetic confinement fusion energy program. The US Department of Energy (DOE) has chosen the Princeton Plasma Physics Laboratory (PPPL) as the preferred location for this ignition research device. The specific proposed site at PPPL is adjacent to the existing Tokamak Fusion Test Reactor (TFTR) test cell. One of the necessary early planning steps in the schedule for the project is compliance with the National Environmental Policy Act (NEPA). Projected environmental impacts of the CIT are minimal. The only unique nonradiological environmental aspect to the project will be releases of relatively large but innocuous amounts of nitrogen gas, as a result of passive liquid nitrogen cooling of the machine. Consequently, potential radiological impacts are of greatest interest. Estimates of releases of tritium and air activation products from the CIT, which may use up to 20 grams of tritium, have been made and consequential doses have been calculated. These preliminary dose calculations indicate that the routine operation design objective dose of 10 mrem/year to the maximally exposed member of the public will be met. Potential accident scenarios have also been developed and the potential effects summarized.
