Lagrangeville, NY, 12540 Email: rovedonivo@optonline.net Phone: 8452235565 General Comment I am concerned about the IP decommissioning by Holtec. Problems with Holtecs planned spent fuel handling and dry storage systems include:
Cask and Canister issues: 20 - 25 year warranty on canisters and cask system 10 mRem limit in Joint Proposal should be honored (RW), as opposed to 25mRem required by NRC Visual inspection of canisters is not adequate. There are no pressure monitors or relief values to assess and protect canister integrity. The Nuclear Waste Technical Review Board.recommends that Spent Nuclear Fuel (SNF) and its containment must be maintained, monitored, and retrievable in a manner that prevents radioactive leaks and hydrogen gas explosion.
Holtec plans to continue to use a containment system for Spent Nuclear Fuel (SNF) of thin-walled canisters inside thicker concrete casks lined up like bowling pins on a concrete tarmac -- a configuration which is more vulnerable to terrorism than Hardened Onsite Storage (HOSS), which could be much safer and should be explored. In Europe and many other countries nuclear waste is stored in more robust canister systems (10 - 20 thick) and often in hardened buildings.
High Burnup Fuel: About 60% of Indian Points spent fuel inventory is high-burnup (HBU) fuel, which is much hotter and more radioactive than ordinary spent fuel, and requires at least seven years or more before moving it to dry cask storage. Holtecs plan to compress this process to three years or less may reduce costs, but also puts workers and the surrounding community in jeopardy.
Inadequate Site Remediation: Holtecs preliminary Post Activities Shutdown Report (PSDAR) indicates that it will do nothing to remediate radiological contamination known to be leaking into the groundwater and the Hudson River, and that it will only superficially remediate contaminated soils, blob:https://www.fdms.gov/168e1adf-e2b2-4adc-ae06-5dfe7a65c382 1/2
10/20/21, 1:04 PM blob:https://www.fdms.gov/168e1adf-e2b2-4adc-ae06-5dfe7a65c382 Radiation Monitoring: Holtecs Post shutdown plan makes no provision for effective, accurate, off-site radiation monitoring despite the fact that radioactive particles and gasses are expected to be released into the air during the demolition of structures on site. The NRC has no requirement for offsite monitoring and therefore absolves Holtec from paying for it. There is also no plan to detect increasing pressure or temperature, container crack formation, or other problems that can lead to radiation leakage from the sealed thin-walled canisters they plan to use.
Perimeter monitoring is not adequate to capture issues directly at the work site which can impact the workers.
Offsite monitoring is needed, especially at nearby elementary school.
At Bruce Units 1 & 2 in Ontario, Canada more than 500 workers were exposed to radioactive dust and volatilized isotopes while cutting channel tubes that needed to be replaced.
Pipeline Risks: Indian Point is not only located at the intersection of two earthquake faults, it is also unique in that it has the Algonquin and a new 42 high-pressure AIM gas pipeline plus other pipelines running under and adjacent to the facility. No other nuclear site in the nation is so threatened by pipelines.
Demolition work inherent to decommissioning elevates the hazard. NYS and multiple independent experts recognize the risk. However, the pipelines are not even mentioned in Holtecs PSDAR. The NRCs Office of Inspector General (OIG) harshly criticized the NRC staff for dismissing the danger of an explosion as not credible, and instead ignoring key data and tailoring its modeling of explosion risks to fit the desired foregone conclusion that no action is necessary.
Earthquake Zones should be studied further ; information from Columbia University Lamont Dougherty Earth Observatory (LDEO)
North Anna: Dominion is seeking a license to build a new plant, despite the Aug. 23 earthquake at North Anna 1 & 2, which didnt meet seismic standards -- but they are now designing Unit 3 to do so. Units 1 &
2 are still operating.
Information on two earthquake zones has been scrubbed from the record.
Emergency Planning and Response is not adequately covered by funding or planning.
Transportation: Holtecs plan envisions shipping Indian Points radioactive waste, including highly radioactive spent fuel, down the Hudson River by barge. Barging contaminated materials down the Hudson River through NY Harbor poses a risk to river towns and the greater NYC Metropolitan area. As the high-level nuclear waste is transported across the country, it will threaten the safety of communities along the transport routes, especially EJ populations in under-represented cities and rural areas. A 2019 Department of Energy (DOE) Gap Analysis indicates that more needs to be understood about the impact of changing the vertical orientation used in dry cask storage to a horizontal orientation for transport and it recommended additional modelling, which is not being done. The infrastructure along transportation routes is aging.
