Tension relationships were determined in steel cable passed through a stump notch and anchored to another object. Tensions were measured in the cable coming into and leaving the notch with one full wrap on the stump. Data was collected from two sites with two test stumps (15.7 to 37.5 inches...
The purpose of this study was to develop a model to calculate
gamma ray pulse height distributions that closely approximate
measured ones. The model was used to produce a pulse height
distribution for a postaccident coolant sample from a nuclear
reactor. Lower limits of detection were calculated for certain key...
The stability analysis for a heated tube system is an
important safety feature of a nuclear power plant.
Although the system theory is well established for linear
systems described by ordinary differential equations, there
is still a shortage of theory dealing with a distributed
system, which is described by partial...
Of great benefit, but not limited to seafloor mineral
exploration, is a technique that fairly rapidly determines the
composition of a drilled vibracore (in a time comparable to the time
involved in obtaining the core). The rapid assessment is desired to
predict whether a given region warrants further exploration by...
An integrated sampling and gamma ray spectrometry system has
been developed for analysis of TRIGA reactor primary cooling water.
A microcomputer controls pumps and valves using BASIC and assembly
language programs to pump 300 ml liquid samples into a reference
geometry surrounding a Ge(Li) detector. Gamma ray spectra are
acquired...
A personal computer with a Data Acquisition and
Control Adapter interface has been used to monitor the
power of the Oregon State University TRIGA Reactor, and
from the time behavior of the reactor power the reactivity
has been computed using the point kinetics equations and
displayed on a digital read-out...
This project implements the control of an AUTOMATIC GAMMA
WELL counting system with an AIM-65 microcomputer. All
states and control signals to and from the AIM-65 are
obtained via three VIAs (Versatile Interface Adaptors).
Motor controls were implemented using triacs, operational
amplifiers and TTL logic devices while the RTC (Real...
To distinguish americium-241 in human lungs from
translocated activity in the tracheobronchial lymph
nodes (TBLN), two intrinsic germanium detectors were
collimated with 0.3-cm lead sheeting.
A tissue-
equivalent phantom containing either 620 nCi (22.9 kBq)
in the lungs or a 2200 nCi (81.4 kBq) TBLN point source
was counted; as...
