Aeration System Design for Improved Intake Water Quality
ENERCON was contracted to perform a hydraulic study, including computational fluid dynamics (CFD) analysis, to evaluate the feasibility of aeration systems for a commercial nuclear power plant. The goal of the aeration system is to raise dissolved oxygen levels and improve survival rates of aquatic wildlife impinging on the plant’s intake fish screens. This is a complex challenge due […]

Generator and Transformer Relay Retrofit
ENERCON’s Electrical Analysis Group (EAG) supported a design change package for upgrading the generation protection system at a two-unit U.S. Boiling Water Reactor nuclear facility. The project involved replacing outdated electromechanical relays with modern digital/microprocessor-based relays to improve protection for the main generator, main transformer, and unit auxiliary transformers. The following protective functions were included in the protective relay replacement: Phase overcurrent Neutral ground overcurrent Negative […]

GOTHIC Modeling Program used to Modernize Analyses of Record
Enercon Services Inc. (ENERCON) developed advanced GOTHIC flooding models for a U.S. commercial nuclear plant to modernize and enhance the flexibility of existing Analyses of Record (AOR), which were originally based on hand calculations. By transitioning to GOTHIC, a state-of-the-art computer code modeling program, our team enabled more dynamic and detailed simulations of potential flooding […]

Emergency Feedwater Turbine Controls Upgrade
ENERCON completed an analog to digital upgrade of the speed control system for the safety related Nuclear Emergency Feedwater (EFW) Turbine. The original Terry Turbine analog control system was obsolete and subject to maintenance challenges including difficulty in obtaining spare and replacement parts. The upgraded control system includes a modern, digital, commercial-grade dedicated Woodward governor […]

Circulating Water Pump Digital Relay Upgrades
ENERCON recently completed a plant design modification that upgraded the existing electromechanical (analog) protection relays for two 9000 HP, 6.9 kV Circulating Water Pump (CWP) motors to new solid-state (digital) relays. The objective was to harden the CWP motor protection circuits by implementing modern solid-state electronic equipment and eliminating legacy electromechanical devices that can lead […]
