asme interpretationsRoger F. Reedy has extensive experience working on the design and construction of pressure vessels, piping, and nuclear power components. His experience includes design, analysis, fabrication, and erection of pressure vessels and piping components for petroleum, chemical, nuclear, fossil fuel, and other industries, including development and implementation of applicable quality systems. His background encompasses nuclear reactors and containment vessels, as well as pressure vessels and storage tanks for petroleum, chemical, and other energy industries. Mr. Reedy is an acknowledged expert in the construction of pressure vessels and nuclear components, including nuclear waste transportation casks and storage canisters, meeting the requirements of the ASME Boiler and Pressure Vessel Code, Section III, Divisions 1, 2 and 3, Section VIII, Divisions 1 and 2, and Sections I, II, V, IX, and XI, and piping to the requirements of ASME B31.1 and B31.3. He is also an expert in implementation of practical quality programs for designers, fabricators, installers, and owners of industrial equipment and plants.

Prior to establishing himself as a consultant, Mr. Reedy worked at Chicago Bridge and Iron Company. While at CBI, he was responsible for the Code design and analysis of Section VIII pressure vessels, multilayer vessels (up to 16 in. thick), nuclear containment vessels, and nuclear reactor vessels. He has designed hundreds of pressure vessels, including some of the first heavy-wall pressure vessels to meet the provisions of the ASME Section VIII, Division 2, Pressure Vessel Code. Subsequent to leaving CBI, he has been involved in licensing, engineering reviews, welding evaluations, quality program evaluation and implementation, project coordination, and ASME Code training of personnel. He has testified as an expert witness in litigations and before regulatory groups on topics such as design criteria, engineering analysis, fabrication techniques, material and welding applications, material control, and construction practices. He has also provided expert witness testimony in the areas of quality control/quality assurance, construction practices, design, welding and application of ASME Codes and Standards for many technical litigation proceedings.

For a number of years, Mr. Reedy has been writing a summary of all changes made to the ASME Boiler and Pressure Vessel Code, and B31.1 and B31.3 Piping Codes as they are published in each Addenda. This information is maintained in a computer database, RA-search, which identifies changes to the Boiler and Pressure Vessel Code and the Piping Codes as far back as 1952. RA-search also contains the full text of all ASME Code Interpretations published since 1977, in the searchable data base. Also on the database is a history of the ASME Boiler and Pressure Vessel Code from 1914 (1st edition of the code) to 1952.

Mr. Reedy has served on ASME Boiler and Pressure Vessel Code Committees for many years in development of Code design, construction, and quality criteria for pressure retaining components. He recently served as chairman of the ASME Section III Committee for Nuclear Power Plant Components, and as a member of the ASME Boiler and Pressure Vessel Main Committee. He was also a member of the ASME Board on Nuclear Codes and Standards. He belongs to the N626.3 Committee, that developed the rules concerning duties and responsibilities of engineers designing ASME Code components for nuclear power plants.

Mr. Reedy was one of the founding members of the ASME Pressure Vessel and Piping Division, which is devoted to the cause of advancing knowledge and techniques for Code design and construction of pressure retaining equipment, and was Chairman of the Division. This Division is now one of the largest in ASME.

Mr. Reedy is a registered Structural Engineer and Professional Engineer. He is a recipient of the ASME Bernard F. Langer Award, the ASME Centennial Medal, and is a Life Fellow of ASME. Recently, Mr. Reedy was made an Honorary Member of the ASME Boiler and Pressure Vessel Main Committee.

REEDY ENGINEERING, INC. (Formerly Reedy Associates, Inc.)
San Jose, CA

In 1984, Mr. Reedy was the prime mover for the origination of the Nuclear Construction Issues Group (NCIG). NCIG was formed to resolve issues related to welding, quality assurance, design reconciliation and other construction issues of concern at nuclear power plants.

Mr. Reedy developed and maintains RA-search, a database containing all ASME Interpretations and a commentary on all ASME Code revisions as far back as 1950.

Currently consulting with utilities, manufacturers and architect/engineers on fabrication, quality assurance, design, general ASME Code issues, and NRC regulatory issues. Also participates as on expert witness in litigations.

San Jose, CA
Successively Manager, Special Projects and Chief Consultant

As Manager, Special Projects, he was responsible for managing the quality assurance consulting group and monitoring the General Electric Mark I Containment Modification Project. His experience and ASME Code expertise was a key element in working with the utilities to define and execute a modification program for 16 nuclear power plants, that was acceptable to the U.S. Nuclear Regulatory Commission.

As Chief Consultant, he served as ex-officio advisor to all in-house projects and all clients on design, quality, and construction questions concerning application of the ASME Code.

Oak Brook, IL
Successively Designer, Staff Engineer, Project Engineer, Design Manager,
and Senior Engineer

Duties included design of pressure vessels and storage tanks, including cryogenic vessels, vacuum chambers, multilayer vessels, environmental chambers, large autoclaves, and high pressure chambers. His duties required close liaison with shop and field personnel, providing Mr. Reedy with an intimate knowledge of practical shop and field construction techniques including the applicable quality requirements and implementation. In 1966, he led the effort to develop the company’s first Quality Assurance Program for a NASA project.

He was responsible for ASME Code design of more than 50 containment vessels and was Design Manager for most of the nuclear vessels fabricated by CBI, including the first field-erected nuclear reactor.


B.S., Civil Engineering, Illinois Institute of Technology

Post-graduate work in structural design and analysis.
