Analysis of LOFT pressurizer spray and surge nozzles to include a 450/sup 0/F step transient

Description: This report presents the analysis of the LOFT pressurizer spray and surge nozzles to include a 450/sup 0/F step thermal transient. Previous analysis performed under subcontract by Basic Technology Incorporated was utilized where applicable. The SAASIII finite element computer program was used to determine stress distributions in the nozzles due to the step transient. Computer results were then incorporated in the necessary additional calculations to ascertain that stress limitations were not ex… more

Remote Working Level Monitor. Final report

Description: The Remote Working Level Monitor (RWLM) is an instrument used to remotely monitor the RN-daughter concentrations and the Working Level (WL). It is an ac powered, microprocessor based instrument which multiplexes two independent detector units to a single central processor unit (CPU). The CPU controls the actuation of the detector units and processes and outputs the data received from these remote detector units. The remote detector units are fully automated and require no manual operation once … more

Uranium production in thorium/denatured uranium fueled PWRs

Description: Uranium-232 buildup in a thorium/denatured uranium fueled pressurized water reactor, PWR(Th), was studied using a modified version of the spectrum-dependent zero dimensional depletion code, LEOPARD. The generic Combustion Engineering System 80 reactor design was selected as the reactor model for the calculations. Reactors fueled with either enriched natural uranium and self-generated recycled uranium or uranium from a thorium breeder and self-generated recycled uranium were considered. For enri… more

Performance evaluation of in-service, elevated temperature industrial insulation

Description: A purchaser of industrial insulation is concerned with many factors which bear on the type of insulation selected. One of the most important factors, undoubtedly, is the thermal conductivity. The thermal conductivity is a measure of the ability of an insulation to conduct heat. The lower this value the better the insulation appears to the buyer. In the past it was generally assumed that the conductivity during the life of the insulation could be taken as a fixed property so long as external inf… more

Goals study for technical development and economic evaluation of the compound parabolic concentrator concept for solar energy collector applications

Description: The Argonne National Laboratories, contracted with Arthur D. Little, Inc. (ADL), to perform a 6 week goal study for the purpose of evaluating the technical applicability and the economic viability of the compound parabolic concentrator (CPC) concept for all solar energy applications except large central power plants. During this period, we studied the use of CPC units in a large number of residential, industrial, and commercial applications. The predicted performance of CPC augmented solar coll… more

ORINC: a one-dimensional implicit approach to the inverse heat conduction problem. [PWR]

Description: The report develops an implicit solution technique to determine both the transient surface temperature and the transient surface heat flux of electrically heated rods given the power input and an ''indicated'' internal temperature during a simulated loss-of-coolant accident. A digital computer program ORINC (ORNL Inverse Code) is developed which solves a one-dimensional, transient, lumped parameter, implicit formulation of the conduction equation at each bundle thermocouple position in the Ther… more

Preliminary tests using a laser particle-size analyzer on geothermal brine

Description: A laser light-scattering particle-size analyzer was used for a two-day period under limited field conditions to observe the occurrence and growth of particles in geothermal brines. Tests were conducted under conditions where both pH and rate of cooling to room temperature strongly influence the size and nature of the particulate population, with a low (4.5) pH and rapid quenching favoring slow growth rates. A method for estimating particulate mass in time periods shorter than 6 h from quenching… more

Wave propagation in viscoelastic media

Description: The mathematical formulations of the wave propagation problem in a linear viscoelastic solid are reviewed from the point of view of constitutive equations and the theory of linear physical systems. Various general results from the theory of propagating singular surfaces and from the mathematical theory of hyperbolic equations are applied to the analysis of the wave propagation process. The impulse responses of three viscoelastic media are analyzed by use of asymptotic methods. The three materia… more

Interim report on cold trap alternatives, sodium technology

Description: This is an interim report on the modifications which are being made to an existing sodium loop so that a new method of removing hydrogen from sodium can be evaluated in a flowing sodium system. Some preliminary results on the performance of this type of cold trap alternative in a static sodium system are reported. Some tentative reactor design parameters for this type of getter device are presented based on the static test results. The life of such a unit is calculated to be substantially great… more

General purpose heat source task group. Final report

Description: The results of thermal analyses and impact tests on a modified design of a /sup 238/Pu-fueled general purpose heat source (GPHS) for spacecraft power supplies are presented. This work was performed to establish the safety of a heat source with pyrolytic graphite insulator shells located either inside or outside the graphite impact shell. This safety is dependent on the degree of aerodynamic heating of the heat source during reentry and on the ability of the heat source capsule to withstand impa… more
