Analysis of ventilation systems subjected to explosive transients: initial analysis and proposed approach. [Deflagration; detonation; transition from deflagration to detonation]

Description: This report describes an initial study of explosive pressure transients and their propagation through ventilation systems. The objective of this study is to organize the required calculations into a computer code that is highly user-oriented and will predict explosive-induced gas dynamics within a ventilation system. The explosive process is subdivided into three regimes - deflagration, detonation, and transition from deflagration to detonation. Equations describing each process and suggested p… more

Analytical validation of the CACECO containment analysis code. [LMFBR]

Description: The CACECO containment analysis code was developed to predict the thermodynamic responses of LMFBR containment facilities to a variety of accidents. This report covers the verification of the CACECO code by problems that can be solved by hand calculations or by reference to textbook and literature examples. The verification concentrates on the accuracy of the material and energy balances maintained by the code and on the independence of the four cells analyzed by the code so that the user can b… more

ANS54: a computer subroutine for predicting fission gas release

Description: The ANS5.4 committee developed fission gas release models for stable and radioactive species for both low and high temperatures. This report reproduces these models and presents a FORTRAN coding of the models. The coding comprises subroutine ANS54 which is in a format suitable for direct insertion into a code like FRAPCON. Also shown are comparisons of model predictions with light water reactor low burnup data and liquid metal fast breeder reactor high burnup data that were used in the model de… more

Application of fluidized-bed technology to the recovery of waste heat

Description: The fluidized-bed, waste-heat boiler (FBWHB) may represent a significant opportunity for industrial energy conservation. The applications of FBWHBs to the recovery of heat from waste streams are examined. Compared to other waste-heat recovery units, FBWHBs can transfer more heat per unit volume and are physically smaller - an important consideration for retrofit and construction costs. A detailed discussion of fluidized beds, including their application in waste-heat recovery and the factors af… more

Automated microscopical method for the characterization of pyrite in coal

Description: The Rapid Scan system of automated reflectance microscopy is a line scanning device capable of characterizing the pyrite content of a coal. The system combines a sophisticated software base with standard hardware components to provide flexibility in analytical format. As a prepared coal sample is moved automatically beneath the microscope objective, reflectance values from adjacent 2 ..mu..m squares are sampled by the photomultiplier tube. These values are stored in computer memory for subseque… more
