A virtual job fair for the Department of Energy’s Nuclear Security Enterprise (NSE) is being held on Wednesday, June 23, from 10 a.m. to 4 p.m. (EDT). The job fair will be hosted by the DOE's National Nuclear Security Administration.

The NSE is looking for the next generation of nuclear security professionals and is planning to hire more than 2,500 new employees in 2021.

Interested candidates are encouraged to register online for the event.

A research collaboration between Lawrence Livermore National Laboratory and the Air Force Institute of Technology (AFIT) has investigated how the neutron energy generated by the detonation of a nuclear device could affect the path and speed of an asteroid on a collision course with Earth by melting and vaporizing a portion of the asteroid. The research, which compared the deflection caused by two different neutron energies—14.1 MeV and 1 MeV, representing fusion and fission neutrons, respectively—is described in an article published by LLNL on April 8.

Every year, Lawrence Livermore National Laboratory releases flowcharts illustrating U.S. energy consumption and use. The flowcharts, called Sankey diagrams, allow scientists, analysts, and other decision makers to compare the contributions made by various energy sources, including nuclear power, and the end uses of those sources, including residential, industrial, commercial, and transportation markets. Taken as a series of annual snapshots, energy use trends and opportunities quickly become apparent.

This year, in addition to releasing the 2019 energy flowchart, the lab issued state-by-state energy flowcharts for 2015–2018 and carbon emissions charts for 2014–2017. It is currently at work on charts of international energy use that it hopes to release by the end of the year.

The sixth and most recent installment in the ANS Young Members Group (YMG) Spotlight on National Labs webinar series explored nuclear science and engineering at Lawrence Livermore National Laboratory on July 16.
