Different stages of the development of new construction materials at NIKIET for innovative designs of reactor installations are analyzed. Justification is given for the use of large-sized intermediate products made of a nickel-based alloy (KhN55MVTs (ChS57) grade) for vessel elements and intermediate products made of molybdenum alloy of the TSM-7 type for the core elements of a high-temperature reactor installation. The next-generation corrosion-resistant steel EP302M-Sh has been developed and introduced for the BREST-OD-300 steam generator, and the production of extra-long pipes made from this steel has been mastered. Research is being performed on a new corrosion-resistant lean-alloyed steel with improved manufacturability metrics (EP750M grade).

NIKIET 分析了用于反应堆装置创新设计的新型建筑材料开发的不同阶段。为容器元件使用由镍基合金（KhN55MVTs（ChS57）级）制成的大尺寸中间产品和由 TSM-7 型钼合金制成的中间产品用于高性能核心元件的理由。温度反应器安装。为 BREST-OD-300 蒸汽发生器开发和引入了下一代耐腐蚀钢 EP302M-Sh，并且已经掌握了用这种钢制造的超长管的生产。正在对一种具有改进的可制造性指标（EP750M 级）的新型耐腐蚀精益合金钢进行研究。
