The U.S. Nuclear Regulatory Commission (NRC) has issued an environmental assessment and a Finding of No Significant Impact (FONSI) for a request from Constellation Energy Generation, LLC. This request seeks an exemption to allow Nine Mile Point Nuclear Station (NMP) to maintain and load multi-purpose canisters (MPC-89-CBS) in a storage system that does not fully comply with existing regulations. The NRC reviewed the potential environmental impacts of granting this exemption and determined that it would not significantly affect the environment. The alternative of denying the exemption would lead to greater risks and challenges, including increased radiation exposure and waste, without providing additional safety benefits.

The U.S. Nuclear Regulatory Commission (NRC) has granted Constellation Energy Generation, LLC, an exemption for their Nine Mile Point Nuclear Station's spent fuel storage system. This exemption allows Constellation to maintain and load multi-purpose canisters (MPCs) with certain design features that do not meet all current safety specifications, as outlined in the existing Certificate of Compliance. However, the NRC has determined that these deviations will not endanger public safety and are consistent with federal laws, while also being in the public interest as they avoid unnecessary risks related to unloading already stored fuel. This decision also helps Constellation manage their storage capacity effectively, ensuring the safe operation of their reactors.
