EFFECTS OF REACTOR RADIATION ON MIX-BIS (MIX-PHENOXYPHENOXY) BENZENE USED AS A LUBRICANT IN A HIGH-SPEED, HIGH-TEMPERATURE BEARING-RIG.
Abstract
A radiation effects study has been conducted on mix-bis (mix-phenoxyphenoxy) benzene - Mixed 5P4E - used as a high-speed bearing lubricant at elevated temperatures. This study, which included evaluations of selected antioxidants in Mixed 5P4E, employed a modified Shell highspeed, high-temperature, ball-bearing rig and the Ground Test Reactor at General Dynamics/Fort Worth. Bearing and bulk-oil test temperatures of 550, 600, and 700 F were employed with axial bearing load of 200 lb at 60,000 rpm during control and test runs. It was concluded that a gamma dose of 2 x 10 to the 10th power ergs/gm(C) plus associated neutrons is approaching the useful upper limit for Mixed 5P4E as a high-speed bearing lubricant at temperatures of from 550 to 600 F. At 700 F this limit is decreased by approximately one order of magnitude. A 0.5% concentration of the antioxidant tetraphenyltin in Mixed 5P4E appeared to improve bearing-rig performance under irradiation. (Author)
