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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

A recuperator is a key component and plays an important role in the high-temperature gas-cooled reactor combined with gas turbine (HTGR-GT) system. A distributed parameter model was proposed to study the dynamic characteristics of the recuperator of the HTGR-GT cycle, and this model was solved using an implicit arithmetic. Basic characteristics of the recuperator were analyzed using responses of the recuperator to step disturbances of temperature and mass flow. The response of the recuperator to the temperature disturbances has two different characteristic times 1 and 2 depending on the relation between the response and the disturbance. The response of the recuperator to mass flow disturbance has a characteristic time 4 that is between 1 and 2. An example of coupled disturbance of temperature and mass flow was simulated by the distributed parameter model. This example shows the influence of the three characteristic times to the dynamic characteristics of the recuperator. When the system power of HTGR-GT is regulated slowly, the core temperature distribution of the recuperator hardly varies. However, when the electric load of the system is rejected from full power, the core temperature, especially in the front of the recuperator, suffers from a drastic change in temperature.
