Subcritical cleaning systems

Recently, systems suppliers have developed subcritical cleaning systems (i.e., systems operating below the critical point for carbon dioxide) that are fabricated using low cost alloy steel coated on the inside with an appropriate plastic to protect it from attack. This approach promises to significantly reduce system costs and enhance the competitive position of carbon dioxide cleaning in less demanding applications. 

A. 1002. This section shall describe systems for storing fresh and spent fuel, for cooling and cleaning the spent fuel pool (if applicable), and for handling and, if necessary, cooling the fuel as it moves within the facility. The quantity of fuel to be stored and the means for maintaining a subcritical array, even during adverse seismic conditions, shall be provided.
