Fifteen sand samples from beaches along the Pacific
North were analyzed for their elemental content by the
method of instrumental neutron activation analysis
(INAA). A separation technique was employed to separate
the zircon (a heavy non-magnetic mineral with a specific
gravity of 4.67) from the rest of the sample. This...
A PC based on-line advanced plant simulator (OLAPS)
for high quality simulations of Portland General
Electric's Trojan Nuclear Facility is presented. OLAPS
is designed to simulate the thermal-hydraulics of the
primary system including core, steam generators, pumps,
piping and pressurizer. The simulations are based on a
five equation model that...
Transition metal and rare earth element (REE) data are presented
for various sedimentary materials from two Manganese Nodule
Program (MANOP) sites in the eastern tropical Pacific. These data
constrain the sources of elemental supply to the seafloor and the
processes that control ferromanganese nodule genesis. Investigation
of elemental partitioning between...
The Three Sisters region of the Oregon High Cascades has developed three compositionally
and petrogenetically distinct silicic (i.e., SiO₂ ≥ 58%) magma systems within the last 600 k.y. These
silicic systems evolved from the same High Cascade mafic magma system and developed in the same
20x30 km area of the...
Two applications of beta spectrometry using active
gamma-ray discrimination are described. The beta spectra
of smears taken at a nuclear power plant at the end of a
300 day shutdown were characterized. The average beta
energy at "contact" (1.5 cm) was between 450 and 550 keV
for locations influenced by...
