IAEA again raises global nuclear power projections
Noting recent momentum behind nuclear power, the International Atomic Energy Agency has revised up its projections for the expansion of nuclear power, estimating that global nuclear operational capacity will more than double by 2050—reaching 2.6 times the 2024 level—with small modular reactors expected to play a pivotal role in this high-case scenario.
IAEA director general Rafael Mariano Grossi announced the new projections, contained in the annual report Energy, Electricity, and Nuclear Power Estimates for the Period up to 2050 at the 69th IAEA General Conference in Vienna.
In the report’s high-case scenario, nuclear electrical generating capacity is projected to increase to from 377 GW at the end of 2024 to 992 GW by 2050. In a low-case scenario, capacity rises 50 percent, compared with 2024, to 561 GW. SMRs are projected to account for 24 percent of the new capacity added in the high case and for 5 percent in the low case.
C. Rogers McCullough was the second president of the American Nuclear Society, where he was also made a Fellow. He was a founding member of ANS’ Standards Committee.
Dr. McCullough was born on January 13, 1900. In 1946, he became director of the Power Pile Division of Clinton Laboratories of the Manhattan Engineer District (now Oak Ridge National Laboratory). The task of this division was to develop and build an experimental reactor using the reactor concept known as the Daniels Pile. This effort was terminated in 1947.
Subsequently, Dr. McCullough worked in chemistry and nuclear engineering at Monsanto Chemical Company. During his time at Monsanto, he served on several committees of the Atomic Energy Commission. He served first as chair of the Industrial Committee on Reactor Locations Problems in 1951. In 1953, that committee merged with another AEC committee and became the Advisory Committee on Reactor Safeguards, which he also chaired. He served as chair of the ACRS until 1960, and continued on as a member until 1961. In 1956, Monsanto placed him on a leave of absence to work full time for AEC as deputy director for hazards evaluation. He held that position concurrently with the ACRS position until mid-1957.
He later became a consultant in chemical and nuclear engineering and served as Technical Director of Southern Nuclear Engineering, Inc., a company offering professional engineering services to nuclear and affiliated industries. Among his consulting assignments, in 1966 he consulted for Consolidated Edison on the Indian Point 2 Nuclear Power Plant, and later, on Indian Point 3.
He was a member of a number of professional organizations, including the American Chemical Society and the American Institute of Chemical Engineers, and was also Vice Chairman of the Reactor Safety Committee of the Atomic Industrial Forum, a member of the technical committee N-45 of the United States of America Standards Institute (now the American National Standards Institute, or ANSI), a member of the Subcommittee on Nuclear Power of the Boiler and Pressure Vessel Committee of the American Society of Mechanical Engineers, and Chairman of a Task Group of this same committee to write Criteria for Prestressed Concrete Reactor Vessels.
He received a bachelor’s degree from Swarthmore College in 1921, and master’s and doctorate degrees in chemistry from MIT in 1922 and 1928, respectively.
C. Rogers McCullough passed away in February of 1967.
