Deck T7- DCD-104-83 LJ-309-3 Retractable Heater Valve Packing - Mo IV Reactor X-ray fluorescence identified the packing material to be of asbestos. This test method and infrared analyses failed to define the presence of fluorine. This informa tion, `'as well as the general appearance of the packing material, strongly indicated the packing was wholly of asbestos with no Teflon present. It is possible, however unlikely, that the Teflon was "burned out" during service. The physical dimensions indicated otherwise. I hope this information fulfills your request. cc: W. T.
