Contents

Nuclear Science and Engineering is the interdisciplinary field concerned with the properties of atomic nuclei, nuclear reactions, radiation, reactor systems, and materials for energy and non-energy applications. It integrates experimental and theoretical methods from Enrico Fermi-era research through contemporary efforts at institutions such as Lawrence Livermore National Laboratory, Argonne National Laboratory, Oak Ridge National Laboratory, CERN, and Rutherford Appleton Laboratory. The field spans contributions by pioneers like Marie Curie, Ernest Rutherford, Lise Meitner, and industrial programs at General Electric, Westinghouse Electric Company, AREVA, and national agencies including the United States Department of Energy and Japan Atomic Energy Agency.

Introduction

The discipline rests on nuclear models developed by Ernest Rutherford, Niels Bohr, and James Chadwick and on experimental probes from accelerators at CERN, Brookhaven National Laboratory, SLAC National Accelerator Laboratory, and TRIUMF. Key phenomena include nuclear fission discovered by Otto Hahn and interpreted by Lise Meitner, nuclear fusion studied in tokamaks like JET and ITER, and decay processes characterized by Marie Curie, Enrico Fermi, and Paul Dirac. Theoretical formalisms draw from work by Richard Feynman, Hans Bethe, Eugene Wigner, Victor Weisskopf, and computational advances using supercomputers at Lawrence Livermore National Laboratory and Argonne National Laboratory.

Reactor engineering evolved from the first sustained chain reaction led by Enrico Fermi at Chicago Pile-1 to commercial fleets operated by utilities such as EDF Energy and Kansai Electric Power Company. Reactor types include light-water reactors developed by Westinghouse Electric Company and General Electric, pressurized heavy-water reactors from AECL, boiling water reactors used in Fukushima Daiichi Nuclear Power Plant, fast breeder reactors such as the BN-600 and research reactors at Oak Ridge National Laboratory. Advanced concepts pursued at MIT, ITER, Culham Centre for Fusion Energy, General Atomics, and TRIUMF encompass small modular reactors championed by NuScale Power, molten salt reactors researched by Oak Ridge National Laboratory, and high-temperature gas-cooled reactors developed with participation from China National Nuclear Corporation.

Radiation science traces to investigations by Marie Curie and regulation by agencies like the International Atomic Energy Agency and the Nuclear Regulatory Commission. Dosimetry and radiological protection standards reference committees such as the International Commission on Radiological Protection and practice in hospitals using equipment from Siemens Healthineers, GE Healthcare, and Varian Medical Systems. Emergency response frameworks were refined after incidents involving Chernobyl disaster and Fukushima Daiichi nuclear disaster with participation from World Health Organization and United Nations Scientific Committee on the Effects of Atomic Radiation. Medical applications connect to work by Marie Curie and contemporary programs at Memorial Sloan Kettering Cancer Center and MD Anderson Cancer Center.

Materials science builds on metallurgical research at Oak Ridge National Laboratory and Los Alamos National Laboratory to manage cladding, corrosion, and radiation damage in alloys such as zirconium alloy trials by AREVA and advanced fuels studied at Idaho National Laboratory. The fuel cycle involves mining operations by Cameco Corporation and Kazatomprom, enrichment technologies developed by URENCO and Areva NC, reprocessing facilities exemplified by La Hague and historical programs at Sellafield, and waste management projects like the Yucca Mountain nuclear waste repository proposal and Finland’s Onkalo repository project. Nonproliferation efforts link to International Atomic Energy Agency safeguards and treaties such as the Comprehensive Nuclear-Test-Ban Treaty.

Beyond electricity generation, the field supports medical therapies at Dana-Farber Cancer Institute and Johns Hopkins Hospital, industrial radiography used by Siemens divisions, isotope production at Oak Ridge National Laboratory and TRIUMF, space power systems developed by NASA and radioisotope thermoelectric generators used in Voyager and Curiosity (rover). Naval propulsion programs originate from work at Admiral Hyman Rickover-led initiatives and are operated by navies including the United States Navy and French Navy. Commercialization and startups like NuScale Power and research consortia including Electric Power Research Institute and Generation IV International Forum drive innovation in reactors, fuel cycles, and fusion technology.

Safety regimes evolved through regulatory responses to the Three Mile Island accident, Chernobyl disaster, and Fukushima Daiichi nuclear disaster with policy actions by bodies such as the Nuclear Regulatory Commission, International Atomic Energy Agency, European Commission, and national ministries like Ministry of Economy, Trade and Industry (Japan). Arms control and nonproliferation intersect with treaties and institutions including the Non-Proliferation Treaty, Comprehensive Nuclear-Test-Ban Treaty Organization, International Atomic Energy Agency inspections, and diplomatic negotiations exemplified by the Joint Comprehensive Plan of Action. Public debate and stakeholder engagement involve environmental organizations like Greenpeace and industry groups such as the World Nuclear Association and Nuclear Energy Institute.
