FIELD: nuclear industry and other industries using parts suffering in operation impact of liquid-metal temperature and corrosion.
SUBSTANCE: in manufacturing fuel element with heat-transfer liquid-metal layer use is made of not pure lead but its alloy incorporating chemical elements of fuel element cladding in amount affording chemical equilibrium of fuel element cladding with contacting heat-transfer lead layer under temperature and other operating conditions. Using low-alloyed lead instead of high-cost pure lead enhances corrosion resistance of fuel element cladding.
EFFECT: enhanced service life and reduced production cost of fuel elements.
