Presentation by David J. Allard, MS, CHP, FHPS, Chairperson, TMI Unit-2 Citizens Advisory Panel, Retired Director, PA DEP Bureau of Radiation Protection

Abstract -Three Mile Island Units 1 & 2 offer an interesting case study related to nuclear power. This presentation will explore: relevant radiation protection standards and regulations; the March 1979 Unit-2 accident, response and recovery; the failures in communications at that time; offsite public radiation dose and potential public health impact; pre- and post-accident monitoring of the public for radiation exposure and effects; a related major class-action health effects legal case; psychological impact on the community; the restart of Unit-1 in the mid-1980s, shut-down in September 2019, and another restart expected in late 2027. Other aspects to be reviewed include: spent nuclear fuel generated during operations of Unit-1; radioactive waste from the past and current cleanup / decommissioning of Unit-2; ongoing radiological environmental surveillance; the local and national concerns related to onsite spent nuclear fuel storage, long-term transport and disposal of SNF; the US NRC’s proposed radiation protection regulation changes; as well as the future of nuclear power with increasing public acceptance being examined.
