Fires within nuclear containment have occurred when the lubricants used in reactor coolant pump motors have leaked or spilled onto the hot insulated main coolant piping. This project was directed toward determining the applicability of commercially available fire resistant fluid lubricants to the lubrication of the bearings of a reactor coolant pump motor. This report describes the evaluation of candidate fluids, the testing of these fluids, and the selection of a lubricant for use in a standard reactor coolant pump motor test. The test results indicated that the phsophate ester lubricants, when properly inhibited and maintained, are acceptable for use. Recommendations are presented for further work necessary to the successful application of the fire resistant fluid lubricant.
