AES has teamed with PCI to design and install PWR Sump strainers at numerous PWR units. The sump screen replacements include design, analysis and is construction of the strainer modules, suction piping connecting strainer modules to the sump, sump plenum components and supporting elements. The strainers have been designed and analyzed for DW, debris loads, differential pressure due to debris and seismic loads.

AES has worked with Prairie Island to install replacement Containment Fan Coil Coolers for both Units 1 & 2. We have provided engineering services covering the entire replacements starting with Procurement Specification, Modification Package development, structural analysis of the fan coil housing for the new cooling coils, rigging evaluations for moving and installing the coils and outage support.

AES has supported numerous stations including Prairie Island, Point Beach, Kewaunee and Beaver Valley by performing owners acceptance reviews of all Westinghouse calculations and reports. Additionally we provided installation /constructability reviews and structural calculations of temporary component staging and laydown regions for Prairie Island and Point Beach.

AES supported Prairie Island for the replacement of the Unit 1 steam generators. We provided third party reviews of the analyses performed by the steam generator equipment suppliers. Additionally we provided numerous modifications and engineering analysis for miscellaneous piping and supports systems required to support the installation of the new steam generators. On site installation support was also provided during the outage.
