Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

Very promising results with the insertion of twisted tapes in tubular heat exchangers have suggested performance of experiments under more interesting conditions, i.e., at higher pressures (50 atm) with exchangers of larger dimensions (200 cm in length and 1-cm i.d.). The results show a great increase in the forced-convection heat transfer coefficient ranging from 100 to 150% at specific mass flow rates of 70 to 100 g/(cm2 sec). The law of dependence of the Nusselt number on the Reynolds number varies with an exponent unity instead of 0.8. The burnout thermal power increases by 30 to 50%; correspondingly, the burnout qualities increase from 60 to 90%, thus drastically reducing the post-burnout length. Furthermore, within this length there are no characteristic, dangerous temperature oscillations. The present results, together with others cited in the referenced literature, constitute a basis for improvement of the subcritical once-through heat exchangers for pressurized-water and liquid metal fast breeder reactor power plants.
