Since its inception, EPM has been involved several extensive scopes to develop setpoint and scaling calculations at both nuclear and non-nuclear facilities. Our team produced baseline calculations and performed reviews of the Technical Specifications and FSAR for the impact of any changes to determine the potential of an unreviewed safety question. We have also developed scaling setpoint documents, calibration data sheets, and functional test procedures for an entire fleet of fossil units.

Our efforts include providing resolution of difficult I&C-related problems dealing with instrument setpoints and safety limits and resolving I&C-related Limiting Conditions of Operations. Our team of I&C engineers have a comprehensive understanding of both BWR & PWR systems and associated instrument loops based on a long history of Nuclear Steam Supply System I&C interface with General Electric and Westinghouse.

We have a thorough knowledge of PWR I&C technology and have worked with I&C vendors and manufacturers including Rosemount, Foxboro and Westinghouse. Our team of engineers bring with them a complete understanding of instrument loops and corresponding documentation.

EPM can handle all phases of establishing an instrument setpoint calculation program, including preparation of plant procedures to control setpoint calculations and design output documents. EPM’s strength in performing setpoint calculations is in the experienced personnel available to perform the work.
