FIELD: nuclear power engineering; preservation of emergency equipment in sunk-ship nuclear reactor units. SUBSTANCE: proposed method is aimed at lifting and conveying reactor compartments preserved by means of low-cost widespread materials. Method involves isolation of reactor-unit radioactive components from environment by placing liquid solution around reactor unit which covers its pieces of equipment and sets to solid mass. Radioactive components of sunk-ship reactor unit are isolated from environment by filling reactor compartment of ship with brine composed of mixture of salts NaCl and KCl in proportion ensuring reliable crystallization. Brine is supplied to compartment while hot over pipeline at mixture temperature exceeding ambient temperature in reactor compartment by minimum 80 C at end of pipeline when brine is admitted to reactor compartment. Filling reactor compartment with brine is started from low level of reactor space and proceeds upwards until it is completely filled up. EFFECT: reduced cost of materials used for immobilization and temporary preservation of emergency equipment; enhanced safety in lifting reactor compartment, its conveying, and provision for its reuse, recovery, and long-time storage.
