PROBLEM TO BE SOLVED: To provide a reactor container in which the material quantity is reduced by the simplification and reduction in number of flange and gazette, in a reinforced concrete head sleeve for reactor container, and the manufacturing property and efficiency in working in site are also improved. SOLUTION: This container is made of reinforced concrete, and a head sleeve 5 to be connected to a reinforced concrete top slab 11 is formed of upper and lower flange plates 14, 15 provided on the upper and lower ends, and a plurality of gazette plates 16, 17 fixed to the upper and lower flange plates 14, 15 and the periphery of the head sleeve 5. The dimension and number of the gazettes have the relation of (thickness of gazette plate: mm unit)×(flange welding part dimension of gazette: mm unit)×(number of gazettes) >>= a regulated value.
