Abstract

Asbestos-cement (Transite) pipe was installed at the Raft River Geothermal Area in the fall of 1975 and has been used extensively since. The pipe is used to transfer water from the well sites to the testing areas, reserve pits, and reinjection wells. The pipeline was designed to transport approximately 300 F water at 150 psi over a period of time for the present testing program and later, for the 5 MW(e) Raft River Pilot Plant. Numerous line failures have occurred since the original lines were installed. Due to the various causes of the line failures and the extensive downtime which has occurred because of them, further examination of Transite pipe is necessary to determine its future use as completion of the 5 MW(e) pilot plant approaches. The Conversion Technology and Engineering Branch has completed a preliminary study of the effects of SI however, no funding is presently available due to limitations in the budget for the 5 MW(e) pilot plant project. The Mechanical Design Branch is continuing design analysis in an effort to gather information to determine maximum warmup rates for the S&I system. Document type: Report
