Rogers Engineering was contracted to determine the technical feasibility and cost/benefit ratios for Pacific Gas and Electric Company to replace the iron-catalyst/peroxide/ caustic systems with surface condensers and Stretford H{sub 2}S abatement systems for Units 1 through 12 at the Geysers. This Milestone No.1 Report is a 6 week progress report and will not have the cost benefit analyses which is planned for in the Final Report. This report will focus only on Units 1 and-3, which are thought of as typical to Units 2 and 4 in our contract. The work performed analyzes the cooling water cycle for both units and determines the turbine operating back pressure as a function of cold water from the existing cooling towers to the new surface condensers. Any power penalty is noted and assessed to the respective turbine-generator with necessary definition for the reason in heat rate deterioration. The direction of Rogers Engineering Co.'s efforts was the conceptual system analysis for Units 1 and 3. But cooling tower performance differences between Units 1 and 2 influenced the similarity of, the cycle thermodynamics and power output at the generator for these two units. We therefore are reporting on Units One and Two. Units Three …

The environmental impact assessment of the Nova projects (Building 391 Complex) describes (1) the proposed actions, (2) the existing environment in and around the Livermore Valley, and (3) the potential environmental impacts from the construction and operation of these facilities. It shows that the proposed action does not conflict with any Federal, State, Regional, or Local Plans and Programs. Possible alternatives to the proposed action are discussed. However, it is concluded that the proposed actions were the most reasonable of the alternatives and would involve relatively minor adverse environmental impacts.
