McNary-John Day Transmission Line Project

The Department has been assembling and testing heat sources and radioisotope power systems (HSIRPSs), which include radioisotope thennoelectric generators, at the Mound Site in Miamisburg, Ohio, for the past 35 years. After the events of September 11, 2001, a Department-wide review of security identified the need for enhanced security measures at the Mound site to safeguard the materials associated with the Department's HSIRPS assembly and test operations. The Department analyzed a range of options in order to provide for the extra safeguard and security measures. These include either upgrading the safeguard and security infrastructure at the Mound site to enable the program to' remain at its current location or transferring the operations to a more secure building at the Mound site itself. In addition, the Department considered two other alternative locations, the Pantex Plant in Texas and the Argonne National Laboratory-West (ANL-W) Site in Idaho both of which have enhanced security and safeguards measures in place because of other ongoing programs. In compliance with the requirements of NEP A, the Department prepared an environmental assessment to consider the potential environmental impacts associated with actions that might be taken with regard to the future location of the HSIRPS operations.

Small-Scale Geothermal Power Plant and Direct-Use Geothermal Application at Americulture, Inc., Cotton City, New Mexico

The EA addresses the construction and operation of the small-scale, geothermal power plant and the direct use of geothermal fluid exhausted from the geothermal power plant as a heating source for the hatchery. Two system concepts were investigated. The preferred concept involves cascading the spent geothermal fluid from the proposed geothermal power plant to various thermal processes used for fish production. In the second concept, the proposed power plant would not be built, and the fluid from the existing geothermal well would be used for all direct-use operations associated with the project. DOE/NREL will take this opportunity to monitor and evaluate the technical and economic performance of the proposed power plant and the direct-use project. This information will be used to advance the design and use of small-scale geothermal technologies.
