Handbook : The Oak Ridge Research Reactor, Low-Intensity Reactor and Oak Ridge Graphite Reactor

Although this ebook is scanned from old documentation of Oak Ridge's Reactor but this is a very useful material to know about Nuclear Reactor. You will find brief explanations about Oak Ridge stuffs.This book explains about The Oak Ridge Research Reactor, Low-Intensity Reactor and Oak Ridge Graphite Reactor. The Oak Ridge was a place that first fission production had been esthablished and a lot of experiments had been done to improve the nuclear technology.
This documentation explains the characteristics of the ORR, LITR and OGR and their experiments. You will find good and brief pictures of detalied design of those reactors.

Oak Ridge Research Reactor = ORR
This reactor uses MTR-type, enriched Uranium FE and berylium reflectors in a 7x9-elements rectangular lattice with moderation and cooling provided by forcecirculation of demineralized water.

Low Intensity Testing Reactor = LITR
The LITR was the original hydraulic-test-mock-up of the MTR. It was converted to a training reactor for the operting staff of the MTR and subsequently has been used as a testing reactor. This reactor uses MTR-type, enriched uranium FE and berylium reflector pieces in a 5x9 elements laticce with moderation and cooling prvided by forcecirculation of demineralized water.

Oak Ridge Graphite Reactor = OGR
This reactor differs markedly from the ORR and LITR. The OGR is graphite-moderated, air cooled, natural-uranium-fueled reactor. The core and reflector is a 24-ft cube of graphite blocks contain horizontal fuel channels arrenged in rectangular grid with 8-in spacing.

Software : FREECORP V1.0 - a simple corrosion model

[1]...FREECORP V1.0 is a simple corrosion model, strongly rooted in theory, which has been developed exclusively based on public knowledge. Currently, this model is capable of predicting uniform corrosion of carbon steel at a single point in an environment containing carbon dioxide, acetic acid, oxygen, and/or hydrogen sulfide. Iron carbonate film formation, a key factor in carbon dioxide corrosion, is simulated using an empirical correlation to improve the accuracy of corrosion rate prediction. Contributions to corrosion of various corrosion species can be calculated, which enables the exploration of dominant corrosion species in the corrosion process. Furthermore, polarization curves for each individual electrochemical reaction, total cathodic and anodic reactions and polarization sweeps can be optionally displayed. In a case of hydrogen sulfide corrosion, film formation is calculated and concentration profile of H2S across mass transfer layers on steel surface is displayed.

FREECORP is a user friendly Excel add-in which allows rapid corrosion prediction calculation and display of the dominant corrosion mechanism. The program determines the dominant mechanism and displays its graph.

For the case of CO2 dominated corrosion the interface shows a polarization plot:

For the case of H2S dominated corrosion the interface shows a polarization plot:

The user also has the option of performing a what-if analysis by adding or removing individual corrosion species from the calculated model. The result of the corrosion calculations and the corresponding plot can be saved into an Excel file.
