Abstract: The continued use of the Los Alamos Scientific Laboratory (LASL) 3.75-MV Van de Graaff accelerator for the nondestructive assay of nuclear material in support of nuclear safeguards is reviewed. A brief description of the accelerator facility and the small-sample assay station (SSAS) is provided. Factors affecting high-accuracy assay of small samples are outlined. Examples are provided for the assay of uranium--thorium mixtures, low-level uranium samples, and high-temperature gas-cooled reactor (HTGR) fuel rods. Research on delayed-neutron energy spectra, radiation damage to /sup 3/He proportional counters, and /sup 4/He gas scintillators is summarized.
