An Act relative to monitoring dry casks of spent nuclear fuel

This bill requires nuclear power plant operators in Massachusetts to report real-time data on the temperature and gas emissions from dry casks storing spent nuclear fuel to the state Department of Public Health. It also mandates that these facilities fully fund offsite emergency response costs after the reactors close, ensuring that no money from the state's Decommissioning Trust Fund is used for this purpose. The law applies to all plants that have ever generated electricity for retail customers in the state and aims to improve monitoring of radiation risks while clarifying financial responsibilities for cleanup.
