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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

Including fission product vapor interactions with aerosols in reactor accident calculations can significantly alter the predicted consequences of a given accident. For example, a high-velocity, short residence time accident can transport significant amounts of tellurium outside the reactor vessel on the aerosols rather than having the tellurium reacted on the vessel’s metal surfaces. In another scenario, a relatively stagnant situation allows equilibration of the vapor/aerosol interactions and deposition of the aerosols inside the core region. Consequently, most of the fission product vapors remain in the core region with the deposited aerosols. The sorption isotherms of CsOH-Ag, CsOH-Cr2O3, and CsI-Cr2O3 can be represented by modified Freundlich isotherm expressions. In addition, CsOH vapor interacts extremely with the iron species under accident conditions such that 0.6 wt% FeO in the aerosol can remove 10 to 15 wt% of the CsOH emitted in an accident.
