On May 17, 2004, Duratek achieved a significant milestone. The first Duratek makeup water system (ThermexTM H20) was placed into service at Entergy’s Pilgrim Station. ThermexTM H20 receives municipality-supplied water and removes impurities and corrosion products in order to create reactor-grade water. The equipment is state-of-the-art in that it utilizes membrane technology and is highly automated and compact by design. The system is unique in that it incorporates sophisticated in-line chemistry analyzers to ensure the product water is of the highest achievable quality. The water the system produces is of near-theoretical purity.

A significant advantage related to ThermexTM H20 is that it generates no ion exchange resin to be replaced or regenerated. In place of ion exchange resin, the system utilizes a combination of ThermexTM membrane technology in concert with a self-regenerating EDI (electrode ionization) polisher. Use of this technology reduces operating costs, while at the same time negating the need to move resin into or out of the secured area of the plant.

Startup of the system has been characterized as “flawless” by all involved, including the customer. Duratek managed all aspects of system fabrication, installation, and startup. Duratek’s dedication and attention to detail has made this project a resounding success and a great example of excellence in customer care.

Providing makeup water services significantly enhances and complements Duratek’s ThermexTM liquid radwaste processing service line. Customer value is enhanced through a single-service provider providing both makeup and contaminated water treatment.
