Results of a study of the transient performance of the Isotope Brayton Flight System (IBFS) are presented.

The uranium-2 wt percent molybdenum alloy was prepared, processed, and age hardened to meet a minimum 930-MPa yield strength (0.2 percent) with a minimum of 10 percent elongation. These mechanical properties were obtained with a carbon level up to 300 ppM in the alloy. The tensile-test ductility is lowered by the humidity of the laboratory atmosphere. (auth)

Flooding and mass transfer experiments were performed with a CO/sub 2/-air/water system to examine mass transfer characteristics in Goodloe-packed columns of 6.4 and 15.2-cm ID for removal of radioactive Kr from HTGR off-gas. The flooding experiments verified previous correlations for the packing. The plug flow model was selected for calculation of the overall mass transfer coefficient, K/sub L/a. The correlation for K/sub L/a in terms of the molar liquid flow rate, L', is K/sub L/a = 0.359(L')/sup 0.96/ for 7.5 x 10/sup -3/ less than L ' less than 3.4 x 10/sup -2/ in the 6.4-cm column and K/sub L/a = 0.144(L')/sup 0.96/ for 2.7 x 10/sup -3/ less than L' less than 5.5 x 10/sup -2/ in the 15.2-cm column.

A HPGe detector incorporated into a Compton suppression and pair spectrometer yields a continuum suppression factor of over 30. Cryostat housing requirements to obtain such suppression are discussed, sample spectra are presented, and several experiments making use of the HPGe dual system are discussed.

Several new or poorly characterized neutron-rich nuclides were produced and studied at the Brookhaven Medium Energy Intense Neutron facility, MEIN. /sup 190/W decays with T/sub 1/2/ = 30.0 +- 1.5 min, E/sub beta/ = 0.93 +- 0.07 MeV, and ..gamma..'s of 157.6 and 162.1 keV. /sup 196/Os decays with T/sub 1/2/ = 35.0 +- 0.4 min and ..gamma..'s at 126.1, 200.7, 207.0, 257.0, 315.3, 407.6, 522.2, and 628.9 keV. /sup 230/Ra decays with T/sub 1/2/ = 93 +- 2 min to 122 +- 3 sec /sup 230/Ac; ..gamma..-ray energies and intensities are tabulated. A decay scheme is proposed for /sup 190/W, and many of the transitions following the decay of /sup 230/Ac are between known levels in /sup 230/Th.

It is assumed that objects exist, and the consequences and possible tests of these assumptions are examined. Various experiments on particle interactions are considered. (JFP)

Laser plasma experiments at the Lawrence Livermore Laboratory have progressed very rapidly and have achieved new milestones in both the implosion and DT gain in laser fusion targets. New diagnostic methods were also developed for determining the state of the compressed fuel and the plasma processes which are occurring in the absorption and scattering of the laser light incident on the laser fusion pellets. A review of the program is given. (MOW)

A multiple contact adhesion model has been derived to explain the charge observed on silica dust. This model has good agreement with the observed adhesion of microspheres and microballoons. From theoretical arguments, it appeared feasible that surface acoustic waves could be used to overcome the electrostatic adhesion between a particle and surface, and be used to move the particle along the surface in a controllable fashion. In an inverted geometry, evidence for resonance in the hollow microballoons was found. Two distinct modes were observed. These were the breathing mode and the Lamb wave mode associated with resonance of the walls. The measured Lamb wave velocity was 6.15 x 10/sup 5/ cm/sec.

Absolute disintegration rates of specific radioactive products induced by neutron irradition of a sample are determined by spectrometric analysis of gamma-ray emissions. Nuclide identification and quantification is carried out by a complex computer code GAMANAL (described elsewhere). The output of GAMANAL is processed by NADAC, a computer code that converts the data on observed distintegration rates to data on the elemental composition of the original sample. Computations by NADAC are on an absolute basis in that stored nuclear parameters are used rather than the difference between the observed disintegration rate and the rate obtained by concurrent irradiation of elemental standards. The NADAC code provides for the computation of complex cases including those involving interrupted irradiations, parent and daughter decay situations where the daughter may also be produced independently, nuclides with very short half-lives compared to counting interval, and those involving interference by competing neutron-induced reactions. The NADAC output consists of a printed report, which summarizes analytical results, and a card-image file, which can be used as input to another computer code MERGE. The purpose of MERGE is to combine the results of multiple analyses and produce a single final answer, based on all available information, for each element found.
