Response of rupture discs to sodium-water reaction pulses. Final report
A 1/7-scale model of a double rupture disc pressure relief device, designed for the intermediate heat transfer system of a liquid metal fast breeder reactor, was subjected to incident pressure pulses that simulated various sodium-water reaction pulses. General features of the pulses generated were an initial rise in pressure that lasted from 1 to 2 ms followed by a slow decrease in pressure that lasted for more than 50 ms. Pulses with nominal maximum pressures of 50, 100, 150, 200, 400, 600, and 800 psi were generated and transmitted along the pipe to load the rupture discs. The hydrostatic collapse pressure of the spherical cap of the rupture disc, determined by test in the same apparatus, was 250 psi. It is concluded that: (1) incident pressures must exceed half the static collapse pressure to cause rupture and so activate the relief system; and (2) incident pressures above the static collapse pressure result in reflected pressures that are less than the incident pressures.
