David M. Blaies Ph. D.

David Blaies has devoted much of his professional life to the nuclear power industry. As a consultant, he has worked at dozens of nuclear facilities across the United States, Canada, and South Africa, specializing in nuclear refueling and plant operations. Through this work, he developed extensive expertise in the complex systems, procedures, and operational practices that support the safe and efficient operation of commercial nuclear power plants.

His interests extend beyond plant operations to the history and development of the commercial nuclear industry in the United States. In his writing, Blaies combines technical knowledge with practical experience, emphasizing clear communication and real-world application rather than theory alone. This approach has made his work valuable to both seasoned professionals and newcomers entering the field.

Among his most significant achievements was the development of an ALARA (As Low As Reasonably Achievable) radiation-reduction technique designed to reduce the buildup of radioactive cobalt isotopes on reactor surfaces. The method, which involves the use of zinc depleted in the Zn-64 isotope, has been adopted at many nuclear power plants worldwide and has contributed to substantial reductions in radiation exposure associated with reactor piping and valve maintenance.

For this contribution to nuclear chemistry and radiation reduction, Blaies received the Fulcrum of Progress Medal from General Electric. His work is reflected in US Patent No. 4,756,874 and related international patents.
