58 -- A HAND HELD AMMONIA LEAK LOCATOR SOL 9BE3303546P DUE 091595 POC STEVE JANNEY, Tel:713-483-8505 Contracting Officer:LISA REA, Tel:713-483-8395 This is a sources sought synopsis for a hand-held amonia leak locator. The Crew and Thermal Systems Division at the Johnson Space Center is planning to develop a hand held ammonia leak locator that will be used as an Extra Vehicular Activity (EVA) tool. Ammonia is the external thermal transfer fluid for the International Space Station. If the ammonia in the thermal control systems starts to leak, that leak must be located and repaired. The tool must operate in an EVA environment, and it must be capable of detecting a partial pressure of 1.0 X 10-6 torr ammonia in the presence of a 2.0 X 10-6 torr background consisting of N2, CO2, H2O, and O2. Innovative and low cost solutions are being sought. The tool must be shipped to the Johnson Space Center by November of 1998. Dr. John Graf is the technical point of contact at NASA/JSC and can be reached at (713) 483-9226. Information can be mailed to NASA/JSC with attention to Dr. Graf, Mail Code: EC3, Houston TX, 77058. Information can also be faxed to Dr. Graf at (713) 483-5060. (0219)
