Investigation of component failures in downhole geothermal pumping systems. Final report (open access)

Investigation of component failures in downhole geothermal pumping systems. Final report

This study investigated component failures in electric, downhole submersible pumps which prevented the attainment of one year continuous downhole running times in geothermal wells at temperatures up to 375/sup 0/F. The feasibility of a pressurized motor to prevent brine intrusion was investigated, as well as improved pothead and packoff designs, and brine scale buildup on impeller sleeve bearings and thrust washers.

Interim Storage Facility decommissioning. Final report (open access)

Interim Storage Facility decommissioning. Final report

Decontamination and decommissioning of the Interim Storage Facility were completed. Activities included performing a detailed radiation survey of the facility, removing surface and imbedded contamination, excavating and removing the fuel storage cells, restoring the site to natural conditions, and shipping waste to Hanford, Washington, for burial. The project was accomplished on schedule and 30% under budget with no measurable exposure to decommissioning personnel.

Technical considerations for flexible piping design in nuclear power plants (open access)

Technical considerations for flexible piping design in nuclear power plants

The overall objective of this research project is to develop a technical basis for flexible piping designs which will improve piping reliability and minimize the use of pipe supports, snubbers, and pipe whip restraints. The current study was conducted to establish the necessary groundwork based on the piping reliability analysis. A confirmatory piping reliability assessment indicated that removing rigid supports and snubbers tends to either improve or affect very little the piping reliability. A couple of changes to be implemented in Regulatory Guide (RG) 1.61 and RG 1.122 aimed at more flexible piping design were investigated. It was concluded that these changes substantially reduce calculated piping responses and allows piping redesigns with significant reduction in number of supports and snubbers without violating ASME code requirements.

Texas Register, Volume 10, Number 21, Pages 873-900, March 15, 1985

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.
