This legislation, known as the Sanction Russian Nuclear Safety Violators Act of 2025 , aims to address the critical safety concerns surrounding the Zaporizhzhia Nuclear Power Station in Ukraine. It mandates the President to impose sanctions on any foreign person found to have endangered the plant's integrity or safety, or undermined Ukraine's operational control since Russia's full-scale invasion. The specified sanctions include asset blocking , allowing the President to freeze property and interests in property of sanctioned individuals or entities within U.S. jurisdiction. Additionally, individuals subject to sanctions will be deemed inadmissible to the United States , ineligible for visas, and any existing visas will be revoked immediately. However, the bill includes several important exceptions. Sanctions will not apply if admitting an alien is necessary to comply with international obligations, such as the UN Headquarters Agreement. Transactions related to humanitarian assistance , including the sale of agricultural commodities, food, medicine, or medical devices, are also exempt. Furthermore, any foreign person actively seeking to reestablish Ukrainian operational control of the plant or surrounding region will not be sanctioned. The President retains the authority to waive sanctions if deemed vital to U.S. national security, provided Congress is notified.
