Model Tests of the Proposed Intake Structure of the Quad-Cities Nuclear Power Plant

摘要

At 1:24-scale undistorted model of the Quad-Cities Nuclear Power Generating Station intake structure and a portion of the adjacent Mississippi River was constructed to obtain bench mark data of near-field flow patterns for various combinations of the river flow and intake operating conditions with the existing intake structure. A proposed 20-bay intake structure utilizing vertically rotating screen was tested to optimize its location in minimizing the impingement aspect by distributing the flow more or less uniformly along the axis of the intake structure. Additional tests were conducted with structures having fewer than 20 bays. Results indicated which intake structures could meet the Best Available Technology velocity criterion for various plant operating conditions and river discharges.
