Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

The Hydrogen Intermediate and Peak Electrical System (HIPES) is a new proposed system that uses low-cost off-peak electricity or base-load nuclear energy to economically produce electricity for peak electrical demand, spinning reserve, and power regulation. HIPES has three major subsystems. Hydrogen and oxygen are produced from water using (a) off-peak electricity by methods such as electrolysis or (b) steady-state hydrogen production methods such as nuclear-hydrogen production with thermochemical cycles. The two gases are stored in large underground facilities using the same technologies used for the seasonal storage of natural gas. Peak electricity is produced by an advanced steam turbine with a burner that combines stored H2, O2, and water to produce high-pressure 1500°C steam, which serves as feed to a special high-temperature steam turbine with actively cooled blades. The steam plant efficiency is ~70%. HIPES power outputs can be rapidly varied to match changing electricity demand because the slow-response component of a traditional steam system (the boiler) has been eliminated. The economics are based on (a) the low cost of large-scale underground gas storage, (b) a low-capital-cost efficient method to convert hydrogen and oxygen into peak electricity (no steam boiler), and (c) the large differences in the prices of base-load and off-peak power relative to the premium prices paid for peak power production, spinning reserve, and power regulation. The technology, markets, and economics are described.
