Intruder dose pathway analysis for the onsite disposal of commercial radioactive waste
Because of uncertainties associated with assessing the potential risks from onsite burials of commercial radioactive waste, the US Nuclear Regulatory Commission (NRC) has amended its regulations to provide greater assurance that buried radioactive material will not present a hazard to public health and safety. The amended regulations now require licensees to apply for approval of proposed procedures for onsite disposal pursuant to 10 CFR 20.302. The NRC technically reviews these requests on a case-by-case basis. These technical reviews require modeling potential pathways to man and projecting radiation dose commitments. This paper contains a summary of our efforts to develop human-intrusion scenarios and to modify a version of the MAXI computer program for potential use by the NRC in reviewing applications for onsite radioactive waste disposal. The ONSITE/MAXI1 computer software package contains four computer codes. ONSITE is the interactive user interface that allows the end-user to simply and efficiently create and use the radiation-exposure scenarios. MAXI1 is then used with the scenario information to calculate the maximum annual dose to the exposed individual from selected pathways. 1 figure.
