Security Concerns at Ukraine's Zaporizhzhia Nuclear Power Plant Highlighted by Recent Staff Reductions
The Zaporizhzhia Nuclear Power Plant in Ukraine, one of the largest atomic power plants in the world, is facing security challenges due to recent staff cuts implemented by Russian authorities occupying the facility. This worrisome situation has prompted the United Nations nuclear watchdog, the International Atomic Energy Agency (IAEA), to express its concerns and closely monitor the plant's operations. IAEA chief Rafael Grossi, who is currently in Kyiv, stated that his upcoming visit to the plant will focus on assessing the impact of the personnel reductions, as Russia denied access to employees of Ukraine's national operator, Energoatom.
The scale of the reduction in staff at the Zaporizhzhia Nuclear Power Plant is quite significant. Previously employing approximately 12,000 personnel, the current workforce has been reduced to an estimated 2,000 to 3,000 individuals. Grossi pointed out the crucial role played by a sufficient number of skilled personnel in operating such a complex facility. Ensuring the safe and efficient functioning of the plant requires personnel with different specific functions. Any drastic reduction in staff numbers can potentially disrupt the delicate equilibrium of operations.
Although the situation at the plant remains stable for now, Grossi emphasized the fragility and the need for constant care. The IAEA has repeatedly raised alarm about the facility, expressing fears of a potential nuclear catastrophe. Since Russia's full-scale invasion of Ukraine on February 24, 2022, and the subsequent seizure of the Zaporizhzhia plant, the facility has been caught in crossfire repeatedly. While the six reactors have been shut down for several months, the operation of crucial cooling systems and other safety features still depends on a reliable power supply and qualified staff.
During his visit, Grossi intends to examine the stability of the facility's cooling function following the collapse of the Kakhovka Dam in the summer. Additionally, the presence of mines in and around the plant is another cause of concern that requires assessment. However, Grossi clarified that the mines appear to be placed between the two perimeter fences and do not pose an immediate danger to the plant's operation.
Of particular concern is the Russian decision to block access for Ukrainian staff employed by Energoatom, who refused to sign contracts with the Russian operator at the site. The current staff at the plant consists of former Energoatom employees who have adopted Russian citizenship and signed new contracts with the Russian operator. The reasons behind the reduction in personnel are varied, including workers fleeing, reluctance to remain in occupied territory, and objections to working under Russian management. Grossi indicated that Russian authorities claim to be recruiting more staff, an assertion that the IAEA team plans to verify during their visit.
The Zaporizhzhia Nuclear Power Plant, although not generating electricity at present, still holds significant amounts of nuclear fuel that require continuous cooling. The collapse of the dam in June impacted access to the reservoir used for cooling. To cope with this challenge, the plant administration resorted to digging wells. Grossi aims to evaluate the effectiveness of this solution and ascertain how the situation has evolved.
Access to the entire facility of the Zaporizhzhia Nuclear Power Plant for IAEA experts permanently stationed there is limited, as Russian authorities have denied requests to visit certain areas. Grossi acknowledged the presence of anti-personnel mines in some parts of the plant, another cause for concern that he intends to scrutinize firsthand. However, he reassured that the type and placement of the mines do not pose immediate danger to the facility.
The upcoming visit of the IAEA chief to the Zaporizhzhia Nuclear Power Plant, as well as his planned discussions with Ukrainian and Russian officials, underscore the urgency of addressing the security concerns surrounding the facility. The delicate equilibrium and the potential risks associated with inadequate staffing and ongoing conflicts necessitate consistent attention and prompt action to ensure the safety of the plant and prevent any potential nuclear disaster.
