Letter: Our false assumptions
Entergy implicitly reminded us of our false assumptions about SAFSTOR of Vermont Yankee during the Vermont State Nuclear Advisory Panel’s Nov. 14 public hearing at Vernon.
Entergy owns the site and can keep it. The security perimeter around nuclear fuel in dry casks may leave no reusable land.
What if cumulative decommissioning costs exceed the balance of the decommissioning fund due to inflation or deficient investment income?
U.N. International Atomic Energy Agency standards for SAFSTOR (safe enclosure) allow active and passive options (Safe Enclosure of Nuclear Facilities During Deferred Dismantling, 2002, pp. 12-13). “The active option for safe enclosure of the facility is characterized by allowing entry at all times, having dedicated personnel to survey the facility and environmental conditions during the entire storage period and keeping the equipment and systems operational during the safe enclosure period. ... The essential feature of the passive option is the fact that the site is not staffed for the majority of the safe enclosure period but only during periods of inspection and maintenance.”
“Significant safety issues arise from: potential failure of barriers used to confine radioactive materials; unidentified areas of significant contamination; new or unrecognized waste streams; … spread of contamination during maintenance and surveillance activities; … deterioration of buildings, structures, systems and components which may have an impact on safe worker access or on final dismantling; potential impacts of non-radiological component failure on overall safety…” (cited above, Page 8).
