Fontana, M H

The possibility exists that a failure of the EGCR experimental loop piping in the loop equipment cell can induce a failure of the loop piping within the main pressure vessel due to overheating of the experiment and the collapsing pressure exerted by the main coolant gas. Release of the main coolant into the experimental cell would cause the pressure to rise rapidly above the structural design value of 12 psig unless a pressure relief hole were provided. Accordingly, it is intended that each experimental cell be relieved to the containment shell. A study of cell pressure was undertaken on an IBM 704. This analysis showed that rupture discs or blow-out doors providing 4.29 ft/sup 2/ flow area per cell are sufficient to keep the pressure below 12 psig if 4.67-in.- diam. orifices are inserted in the loop piping.
