NNSA furloughs 1,400 employees, pays contractors until end of month
After nearly three weeks of a government shutdown, the Department of Energy’s National Nuclear Security Administration has furloughed 1,400 employees and has retained 400 as essential employees who will continue working without pay.

Measurements have been made of the anisotropy of neutron slowing down in Al-H2O plate lattices. The moments of the slowing down distribution from fission to 1.46 eV were determined in the two characteristic directions at two volume ratios using the point-source, point-detector method. For the 1:1 case, with an Al plate thickness of 0.25 in., the ages parallel and perpendicular to the plates were 65.4 ± 0.8 and 60.8 ± 0.8 cm2, respectively, giving an anisotropy of 1.076 ± 0.02. In the 2:1 (A1:H2O) case, with an Al thickness of 0.50 in., the corresponding values are 100.3 ± 1.5 and 92.5 ± 1.3 cm2, giving an anisotropy of 1.085 ± 0.02. The higher moments were characterized by higher anisotropics.
