Duke Triangle Universities Nuclear Laboratory (TUNL)
ACH Constructors provided general contracting services for renovations and upgrades to the accelerator equipment cooling loop at the TUNL. The cooling loop was converted from a local cooling tower setup to the campus chilled water loop. Additions included new pumps, heat exchanger, electrical power upgrades, controls automation, and piping modifications and additions. New piping and components were installed and staged while the TUNL was operational. A systems shutdown and tie-in changeover was coordinated with TUNL staff to minimize downtime to the facility.
