Development of off-line load sensor characterization of sintered-metal load gauge element (1)

not registered

Characterization has been made on the sintered-metal load gauge element which is under development for use in off-line load measurement in the reactor environment. The shape of the element was determined with due consideration for possible use in the sub-assembly interaction force measurement in the Joyo core. The testing conducted is as follows : (1)Themal Expansion Measurement Test (2)Sodium l㎜ersion Test (3)Compression Tests at Room Temperature (4)Compression Tests at Elevated Temperatures (5)Creep Tests at Elevated Temperature Compression tests for sodium-i㎜ersed elements were also comducted at an elevated temperature. Characteristic data obtained have been highly satisfactory, thereby encouraging further study for practical applications.
