Richard B. Vilim

Manager, Plant Analysis & Control and NDE Sensors

Richard Vilim is a senior nuclear engineer and manages the Plant Analysis & Control and Nondestructive Evaluation Sensors Group within Argonne’s Nuclear Science and Engineering Division.


Richard Vilim is an expert on modeling and simulation of power plants from both an engineering and economic perspective, on power plant instrumentation and control, and on equipment monitoring, with over 35 years experience developing new applications for the process and power industries.

His research focuses on the cost competitiveness of nuclear power operating in both an electric grid with renewables and in hybrid energy systems.  His research also includes the development of signal-processing methods and automated reasoning methods for detecting sensor failure and for the diagnosis of incipient equipment degradation in process systems. He is presently leading the team responsible for designing the instrumentation and control system for an advanced nuclear power plant to be built with international collaboration.

Vilim has over 250 publications and seven U.S. patents. He has developed a number of computer codes in use by others including General Plant Analyzer and System Simulator (GPASS) and Parameter-Free Reasoning Operator for Automated Identification and Diagnosis (PRO-AID). He is one of four Argonne inventors whose patents formed the intellectual property basis for Smart Signal Corporation, a technology startup company with revenues of $30M, recently acquired by General Electric.
