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.

Strontium: Supply-and-demand success for the DOE’s Isotope Program
The Department of Energy’s Isotope Program (DOE IP) announced last week that it would end its “active standby” capability for strontium-82 production about two decades after beginning production of the isotope for cardiac diagnostic imaging. The DOE IP is celebrating commercialization of the Sr-82 supply chain as “a success story for both industry and the DOE IP.” Now that the Sr-82 market is commercially viable, the DOE IP and its National Isotope Development Center can “reassign those dedicated radioisotope production capacities to other mission needs”—including Sr-89.

Novette is a large, two beam, two wavelength laser facility at Lawrence Livermore National Laboratory. The Novette laser projected performance exceeds that of the 20 arm Shiva laser and the frequency multiplying capability provides more efficient target interaction. Novette is comprised of two arms of the Nova laser. New designs allow these two arms to exceed the performance of the 20 arms of Shiva. Assembling these two arms on an accelerated schedule allowed the experimental program to continue with minimum interruption. The laser has been operational since January 1983. More efficient laser amplifiers allowed the performance to be achieved with half the capacitor bank used on Shiva. The pulse power for Novette uses high-density capacitors, instrumented dual ignitron switches, 100 KVA power supplies and a control system based on LSI/11 Front End Processors (FEP's) and fiberoptic links. The bank contains 11 MJ of stored energy at 22 KV. Construction of the pulse power system took a year. The laser was completed in about 15 months. This paper is a summary of the pulse power systems for Novette; the flashlamp power system, the pulsers for the various optical shutters and the pulse power control system.
