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.

A 0.357-o.d. null-balanced pressure transducer was designed and built for 900°F at 350-psig service and tested on the bench for seven months at design conditions and 1200 and 1300°F at 350 psig until failure six weeks later. This type transducer was also tested in conjunction with a fuel irradiation experiment in the CP-5 research reactor. It provided experimentors with fission gas pressure readings until failure of the fuel pin. A unique device was used to control the reference gas pressure. Control was obtained by making use of the change in probe-disk electrical contact resistance. This method allowed the transducer to follow increasing and/or decreasing pressures easily and quickly as it took place. Transducers of this type generally operate on the probe, making and breaking contact with the disk which makes it easy to follow increasing pressure but becomes difficult to follow decreasing pressures. Resolution of the system was found to be ±l/4 psig with an overall accuracy of ±8 psig for full range.
