Experimental Gas Cooled Reactor-Creep Test, Agot Graphite (open access)

Experimental Gas Cooled Reactor-Creep Test, Agot Graphite

Tests were conducted to determine the cumulative and permanent deflection of a beam subjected to two-point loading for (1) ambient temperature- atmospheric environment, and (2) 800 deg F-atmospheric environment, for 8OO psi maximum flexural stresses. Deflection curves are given for five specimens. An analysis of the data indicated that if the core graphite creeps while at EGCR conditions by approximately 1.5 times its creep rate at ambient temperature, the stresses will level off below 1000 psi. Considerable oxidation oc curred for two specimens at 800 deg F. The indicated strain of these specimens may not be representative of AGOT, nuclear grade graphite at 800 deg F in an inert atmosphere.
