Some of the Potential Risks

  • Spent Fuel Pools—overcrowding
  • Aging and Faulty Equipment
  • GE Mark I Design Flaws
  • Expanded Transmission Corridors–CapX2020 impact not fully assessed.
  • Both of Minnesota’s Nuclear power plants (Monticello and Praire Island) were designed for a 40-year window of operation. There are worries that current, increased operating levels align Monticello and Praire Island with equipment, durability and design needed for plants with a 100-year life expectancy. The increased generating capactiy will also create more wear and tear on equipment.
  • Multiple Nuclear Facilities and major transfer points at the Same Location.
  • Total Loss of Power in Station Blackouts (SBOs)
  • Severe Weather Events (earthquakes and other natural disasters)
  • No Plan for Disaster, Unclear Authority, and Limited Funding
  • Limited knowledge re: Long Term Effects of Radiation Exposure. Many daily radioactive by-products continue emitting radioactive particles and rays for enormously long periods – described in terms of “half-lives.” How can we know the full impact of radioactive iodine- 129 if it has a half-life of 16 million years?
  • Limited knowledge re: Environmental Impact. Accurate accounting of all radioactive wastes released to the air, water and soil from the entire reactor fuel production system is simply not available.
  • Limited knowledge re: Contamination of the Mississippi River. Impact on watershed needs to be fully assessed, and effective recovery plans proposed.
  • Un-estimated and underestimated harm from daily radioactive releases.
    1. Radioactive releases from a nuclear power reactor’s routine operation often are not fully detected or reported. Accidental releases may not be completely verified or documented.
    2. Accurate, economically-feasible filtering and monitoring technologies do not exist for some of the major reactor by-products, such as radioactive hydrogen (tritium) and noble gases, such as krypton and xenon.
  • Lack of Fire Protection
  • Terrorism
