摘要:PROBLEM TO BE SOLVED: To provide a reactor pressure vessel having a shell
course including a nozzle fabricated from a single one-piece forging. SOLUTION: The forged nozzle shell course 16 for the pressure vessel includes at least one reinforcing portion 56 extending radially outwardly from the outer surface 58 of the shell course, each of the reinforcing portions including a nozzle 36 having a radius. The nozzle includes
a bore 50 extending from the outer surface 60 of the reinforcing part to the inner surface
52 of the shell course, and at least one extended mounting surface 62 disposed adjacent and coaxial with the bore. The reinforcing part has a londitudinal dimension 74 equal to about twice the radius of the nozzle, measured from the centerline of the nozzle bore, and has a circumferential dimension 72 equal to about 1.5 times the radius of the nozzle.
