    Model Study of Donald C. Cook Power Plant Condensate Drain System
    (St. Anthony Falls Hydraulic Laboratory, 1973-04) Hayden, John
    The construction of the Donald C. Cook Power Plant on the southeast shore of Lake Michigan will result in a significant increase in the total generating capacity of the American Electric Power Service Corporation (AEP). The design of the condensate drain system, which drains condensate from the cross-under piping connecting the high-pressure turbine exhaust to the Moisture Separator-Reheater (MSR) and from the MSR unit, is shown in AEP's Drawing No. MSK-82771

    Model Study of Proposed Expansion - Encina Power Plant San Diego Gas and Electric Company
    (St. Anthony Falls Hydraulic Laboratory, 1971-09) Hayden, John
    Because of present and anticipated future power demands, it is now necessary for the San Diego Gas and Electric Company to expand the generating capacity at its Encina Power Plant. In order to provide sufficient cooling water for the expanded plant, the existing inlet tunnels and associated structures must be modified. Because the complexity of the structure made it essentially impossible to analyze accurately the flow pattern and associated head losses mathematically, a model study was undertaken at the St. Anthony Falls Hydraulic Laboratory. The hydraulic model was built and tested to assist in the development of a satisfactory design and to verify the final design.

    Model Study of the Intake and Discharge Structures for Zion Nuclear Station
    (St. Anthony Falls Hydraulic Laboratory, 1969) Silberman, Edward; Hayden, John
    The Zion Nuclear Station, being built by the Commonwealth Edison Company on Lake Michigan, was designed by Sargent and Lundy of Chicago, Illinois. The plant requires condenser cooling water flows of 3450 cfs during midsummer. Harza Engineering Company, also of Chicago, acted as consultants on the hydraulic design of the intake and discharge structures and determined that a model study would be desirable for checking some of the hydraulic features of these structures. The model studies were conducted at the St. Anthony Falls Hydraulic Laboratory. This report describes the studies and the results thereof.

    Model Study of the Redesigned Intake Structure for Zion Station
    (St. Anthony Falls Hydraulic Laboratory, 1972-03) Hayden, John
    Zion Station on Lake Michigan was designed and is being built by Sargent and Lundy of Chicago for the Commonwealth Edison Company. The intake roof structure as originally designed and constructed was damaged. As a result the Harza Engineering Company, also of Chicago, which acted as consultant on the hydraulic design of the structure, commissioned the St. Anthony Falls Hydraulic Laboratory to conduct a model study of the redesigned roof structure. This report describes the study and its results.

    Seepage and Stability Analysis of Taconite Tailings Basin
    (St. Anthony Falls Hydraulic Laboratory, 1971-07) Hayden, John; Christiano, Paul
    Recent environmental concerns have required an increasing number of tailing ponds for the control of mine tailings and treatment water. Many of these retention pond dikes which have been sealed in some manner to prevent water losses are being constructed with coarse taconite tailings. Although the typical tailings pond dike represents to the laymen a rather ugly pile of waste material, the embankment is a structural mass subject to failure if not properly designed by the mine engineers. Failure of a dike constructed in Northern Minnesota may not be disastrous in terms of loss of life; however, failure would cause serious financial loss as well as damage to the local environment. For these reasons care should be exercised in the design of a tailings pond dike. This study was conducted to assist the Minnesota Ore Operations Department of U.S. Steel Corporation at Mt. Iron, Minnesota, in the design and analysis of the proposed expansion of an existing tailings pond and dike at the Minntac plant. Two aspects were worked on in detail: (1) stability analysis of the various proposed dike configurations for a wide range of values of physical properties for both the dike and the underlying materials; and (2) permeability and seepage analysis of proposed dike materials and dike configurations.
