U.S. energy use rises to highest level ever

April 11, 2019- 
Americans used more energy in 2018 than in any other year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Overall total energy consumption rose to 101.2 quadrillion BTU (or "quads"). The prior record, set in 2007, was 101.0 quads. Energy use went up by 3.6 percent from 2017, which also is the largest annual increase since 2010. Each...

Sandia's Line VISAR has roots in Livermore

April 10, 2019- 
A joint Lawrence Livermore National Laboratory (LLNL)/Sandia National Laboratories team has commissioned a Line Velocity Interferometer System for Any Reflector (Line VISAR) at Sandia’s Z Machine. Line VISAR is used to measure the velocities of shocks and surface motions when enormous pressures are applied to target materials in high-energy density science experiments. Such data inform...

Lab scientists use radioactive tracers to determine the ages of streamflow

April 8, 2019- 
Watersheds store water underground in soils and weathered bedrock. How long it takes for water to flow through the subsurface to feed streams is difficult to measure but important for understanding how watersheds function. Lawrence Livermore National Laboratory (LLNL) researchers and their collaborators have studied the mixture of water ages in Providence Creek, a stream in the southern...

NARAC marks 40 years of emergency response

April 4, 2019- 
It’s been 40 years since the first emergency phone call came in from the Department of Energy to Lawrence Livermore National Laboratory (LLNL). An accident had occurred at the Three Mile Island nuclear power plant on March 28, 1979 that led to a release of radioactivity into the atmosphere. This is how the National Atmospheric Release Advisory Center (NARAC) was born. Over the next 10 days,...

Diving into untouched lunar treasures

March 27, 2019- 
Nearly 50 years ago, some very special materials were transported from outer space to Earth — unopened lunar treasures rocketed back by Apollo moonwalkers between 1971 and 1972. Nine "special samples" were collected in containers during the Apollo 15, 16 and 17 missions that had indium knife-edge seals to maintain a lunar-like vacuum. Apollo mission planners devised these special sample...
