As part of the preparations for the construction of two new AP1000® nuclear reactors in Bulgaria, representatives of Westinghouse Electric Company carried out an official visit to the headquarters and manufacturing facilities of TANGRA – AV Ltd. The purpose of the visit was to conduct a preliminary technical review and assessment of the production processes, quality management systems, and industrial safety procedures.
On November 18th, TANGRA and Westinghouse signed a Memorandum of Understanding (MoU), through which the Bulgarian company is integrated into the potential supplier chain for the expansion of the Kozloduy Nuclear Power Plant with two new AP1000® units. The signing of the MoU confirms TANGRA’s potential to supply high-technology equipment and services, including ventilation and air handling units that meet international safety and quality standards.
The nuclear industry requires the highest levels of precision and reliability. TANGRA has long-standing experience in delivering and integrating ventilation and filtration systems for the Kozloduy NPP, including equipment commissioned as early as 1992–1994, which remains in operation and is still maintained today.
Currently, TANGRA is the only Bulgarian manufacturer of ventilation and air-handling units certified by TÜV and Eurovent, ensuring compliance with leading European requirements for energy efficiency, safety, and air hygiene in critical infrastructure.
The audit and the signing of the memorandum with Westinghouse represent an important indication of confidence in the capabilities of Bulgarian industry and the potential for local companies to participate in strategic high-technology projects in the nuclear energy sector.
“We highly appreciate the opportunity to collaborate with international technology leaders. Such assessments and official partnerships are essential for ensuring transparency, reliability, and competitiveness. This is a step toward deeper integration of Bulgarian manufacturers into the country’s strategic energy projects,” the management of TANGRA stated.
The signed memorandum is part of Westinghouse’s strategy to expand its supplier network in Bulgaria and follows the company’s “Buy Where We Build” philosophy. By expanding its network of Bulgarian suppliers, Westinghouse aims to ensure timely deliveries, high quality, and efficient execution of the projects for the new AP1000® reactors.
