X-WATERS Нуклеар

In 1974, the landscape of the Smolensk region was irrevocably altered by the flooding of the Desna River valley to create a massive cooling reservoir for the newly conceived Smolensk Nuclear Power Plant. Today, the gargantuan silhouettes of the RBMK-1000 reactors loom over the shoreline, serving as both a surreal backdrop and a testament to the engineering scale that defines the venue. Swimmers here navigate a water body that effectively functions as a massive thermal battery, maintaining temperatures that defy the cooling autumn air. This interplay between industrial might and the quiet, marshy banks of the local river tributaries—like the Prismara, which historically marked the transition into Belarusian cultural influences—forms the core of the X-WATERS Nuclear experience.

As you push off from the shore, the water beneath you is part of a complex, man-made ecosystem holding over 0.32 cubic kilometers of water. The currents, particularly for the longer 10km point-to-point challenge starting at the Troyanovsky discharge, are driven by the plant's operational cycles, requiring a full wetsuit to manage the temperature fluctuations and the physical demands of the flow. In contrast, the shorter, wetsuit-free events like the 'minus 5km' distance allow for a more direct interaction with the reservoir’s unique thermal properties. The route frequently aligns with the proximity of the A101 highway, the historic 'Varshavka' road that has long served as a terrestrial artery connecting Moscow toward the western borders.

Logistics for this race are designed to accommodate the remote nature of the site, with registration fees ranging from 4,490 to 13,990 RUB depending on the chosen distance and timing. The event, held annually in mid-September, leans into the industrial aesthetic of the surroundings while maintaining rigorous safety protocols for all entries, including the mandatory use of illuminated buoys for the night swim. By the time you reach the city beach finish, the stark geometry of the power plant yields to the dense, turning foliage of the surrounding pines, grounding the event in the seasonal transition of the Smolensk forests.
