Computer Software Development

MPR Associates has extensive experience in developing computer software for a variety of applications. This has included development of large programs for stress analysis, thermal-hydraulics analysis, and plant dynamics simulations. It has also included software for instrumentation and control system analysis and design, including real-time computer simulations for developing and testing control algorithms and alignment procedures, and evaluating control strategies.

MPR Associates has developed database management software for a number of applications. These software packages have been applied at MPR Associates and have been delivered to and applied by our clients. We have integrated large database management systems in plant mainframe computers.

Software Development Project Summary

Specific examples of computer software developed by MPR include:

• The air-operated valve (AOV) SETPOINT CONTROL SOFTWARE (SCS) is a unique and powerful tool for performing AOV component level calculations, optimizing AOV design and setup, and controlling AOV setpoints.

• Online Monitoring and Diagnostic Systems:
  • SmartSignal eCM—Software interface development for a best-of-breed remote equipment condition monitoring system.

• HMI and Machine Control—Bioscan "LOOP" C-11 Methylation System (Software product design - realtime control and monitoring.

• Custom Application Software:
  • The Transient Performance Advisor (TPA) for diesel engines (i.e. used on the Woodward Model 701 Governor) is a unique, integrated software program model of a diesel engine, its connected loads, and its auxiliary systems. TPA can be used to solve a variety of issues, including predicting engine transient response to loading sequences, evaluating control system stability, and developing tuning criteria.
  • Research Lab Automation for NIH—Developed software bridges between existing incompatible programs (i.e., MetaMorph Offline and NIAMS Automated Custom Image Analysis Add-in.

• Data Acquisition and Analysis Systems:
  • Mine Detection Software—Collects, analyzes and displays spectra data used to "sniff" explosive devices.
  • Navy Submarine Data Processing Unit (DPU)—Third generation hardware and software to collect and analyze health of critical ship systems (PSTD Data Acquisition Program for DPU III - Beta Version).

• Distributed Computing Systems:
  • Ex-USS Shadwell Supervisory Control System—Distributed software applications to facilitate situation awareness and system control during a casualty (Shadwell Firemain SCS Display - Peacetime).

• The PIPEMASTER integrated piping analysis and evaluation system. PIPEMASTER includes pre- and post-processors to facilitate the performance and Quality Assurance verification of ASME Code piping and support analyses.

• The IADA (Instrument Air Diagnostic Advisor) expert system to assist utility engineers in assessing instrument air system performance and identifying system modifications.

• The FLONET and TFHAL programs for transient analysis of the two-phase discharge characteristics of Halon 1301 fire protection systems.

• The SSFLAW program for evaluating integranular stress corrosion cracking in stainless steel piping. SSFLAW performs crack growth calculations to evaluate the need for piping repair or replacement and also performs calculations to design weld overlay repairs.

• The GIDATA database application program. The GIDATA database contains detailed information for motor operated gate valves in nuclear power plants. Utility engineers can use this information to contact other utilities regarding valve performance.

• The FASTFLO program for transient thermal-hydraulic analysis of single and two-phase water and gas piping systems and heat exchangers. Examples of FASTFLO applications include models of nuclear reactor coolant system and steam generator dynamics and fossil boilers.

• The BOLTPro program is a commercially available application for design and evaluation of threaded fastener joints. Common configurations, components, materials and lubricants (including material properties and friction coefficients) are built into the program to allow fast and easy joint evaluations.

• The CONDENS program for evaluation and design of power plant main condensers. CONDENS uses a "first-principles" approach to solve for heat transfer and the equations of state.
