Control room ventilation intake selection for the floating nuclear power plant

To assist in the design of the control room air supply for a floating nuclear plant, a comprehensive wind tunnel measurements program, employing scale models of two floating nuclear power plants located within a scale model of a typical breakwater, was performed at the Colorado State University under the direction of Offshore Power Systems. The purpose of the program was to provide data for: (1) selecting locations on the standard plant for the two alternate control room ventilation intakes, and, (2) determining applicable dispersion factors between the release locations and the selected intakes required for hazard analyses. This paper describes the measurements program and the methods employed by Offshore Power Systems in analyzing the experimental data that lead to the selection of the intake locations and the values of dispersion factors for control room hazard analyses
