General purpose computers in real time

Description: I see three main trends in the use of general purpose computers in real time. The first is more processing power. The second is the use of higher speed interconnects between computers (allowing more data to be delivered to the processors). The third is the use of larger programs running in the computers. Although there is still work that needs to be done, I believe that all indications are that the online need for general purpose computers should be available for the SCC and LHC machines. 2 fig… more

PC-based calculation of activation energy using linear regression

Description: During a severe accident, various plant locations will be subjected to harsh environments: high temperature, high humidity, high radiation, etc. Equipment required for accident mitigation located in these areas must be capable of withstanding these conditions, i.e., environmentally qualified. Qualification is normally accomplished by type-testing. The equipment undergoes accelerated aging to achieve a condition equivalent to the end-of-life condition. This aging consists of accelerated thermal … more

MONO: A program to calculate synchrotron beamline monochromator throughputs

Description: A set of Fortran programs have been developed to calculate the expected throughput of x-ray monochromators with a filtered synchrotron source and is applicable to bending magnet and wiggler beamlines. These programs calculate the normalized throughput and filtered synchrotron spectrum passed by multiple element, flat un- focussed monochromator crystals of the Bragg or Laue type as a function of incident beam divergence, energy and polarization. The reflected and transmitted beam of each crystal… more

TURBOSEIS---An interactive program for constructing and editing models of seismic refraction traveltime data using a color-graphics terminal

Description: TURBOSEIS is a FORTRAN computer program designed to assist the user in interactively developing seismic refraction traveltime curves (models), to evaluate the number of refracting horizons at depth in a study area. TURBOSEIS allows one to generate a detailed traveltime curve for each of these layers that can then be input into the programs of Ackermann (Ackermann and other 1986) for inversion of the velocity distribution as a function of depth. This report describes the mechanics of using the p… more

KAOS-V code: An evaluation tool for neutron kerma factors and other nuclear responses

Description: The accurate evaluation of neutron fluence-to-kerma factors from microscopic nuclear data is the subject of this report. The algorithms developed for this purpose combine in a consistent manner the two basic methods for computing kerma factors, namely kinematics and direct energy balance. These algorithms are implemented in the code KAOS-V which was used as the main evaluation tool to construct the response function library KAOS/LIB-V. KAOS-V uses data from the evaluated nuclear data files ENDF… more

Physics analysis workstation

Description: The Physics Analysis Workstation (PAW) is a high-level program providing data presentation and statistical or mathematical analysis. PAW has been developed at CERN as an instrument to assist physicists in the analysis and presentation of their data. The program is interfaced to a high level graphics package, based on basic underlying graphics. 3-D graphics capabilities are being implemented. The major objects in PAW are 1 or 2 dimensional binned event data with fixed number of entries per event… more

BRANDEX: A FORTRAN/Pascal code to calculate the multiple binary splitting of an excited nucleus

Description: BRANDEX is a statistical calculation based on averages of physical distributions that will predict cross sections for particle coincidence channels resulting from the breakup of an excited nucleus through a sequential binary process. With minor modification, it can make predictions for an arbitrary nucleus, integrating over an arbitrary weighted range of excitation. An example is given for /sup 16/O breakup using the experimentally obtained excitation energy distribution. 4 refs., 6 figs.

Faster-than-real-time simulation for plant control

Description: As part of the advanced diagnostic prognostic analysis and control system, a faster-than-real-time simulation of the EBR-II reactor has been developed using the Digital Simulator for Nuclear Power Plants (DSNP). Other elements of the system include an expert system, advanced graphics display, real time data acquisition using the EBR-II plant computer and a data transmission system coupling the control computers with the plant and graphics display. Various plant models have been constructed with… more

OMNI development of an engineering product data management system

Description: The increasing use of computers in engineering design and manufacturing (CAD/CAM) has been accompanied by the need to effectively manage the data produced, and the applications that produce the data. This paper presents an integrated engineering product data management system (PDMS) called OMNI. OMNI manages the product data, and controls access to the various CAD/CAM applications used to produce engineering data. OMNI is based on a relational data base (RTIRIM) and a FORTRAN interface between … more

Portable parallel programming in a Fortran environment

Description: Experience using the Argonne-developed PARMACs macro package to implement a portable parallel programming environment is described. Fortran programs with intrinsic parallelism of coarse and medium granularity are easily converted to parallel programs which are portable among a number of commercially available parallel processors in the class of shared-memory bus-based and local-memory network based MIMD processors. The parallelism is implemented using standard UNIX (tm) tools and a small number… more

Gas production and behavior in the coolant of the SP-100 Space Nuclear Power System

Description: The radiologic generation and subsequent behavior of helium gas in the lithium coolant of SP-100 class space nuclear power reactors was investigated analytically in a two part study. Part One of the study consisted of a calculation of coolant radiologic helium gas production rates in a SP-100 class reactor using the discrete ordinates code TWODANT. Cross sections were developed from ENDF/B-V data via the MATXS6s master cross section library. Cross sections were self shielded assuming one homoge… more

An MS-DOS-based program for analyzing plutonium gamma-ray spectra

Description: A plutonium gamma-ray analysis system that operates on MS-DOS-based computers has been developed for the International Atomic Energy Agency (IAEA) to perform in-field analysis of plutonium gamma-ray spectra for plutonium isotopics. The program titled IAEAPU consists of three separate applications: (1) a data-transfer application for transferring spectral data from a CICERO multichannel analyzer to a binary data file, (2) a data-analysis application to analyze plutonium gamma-ray spectra for plu… more

An empirical computer model of the F-Area A-Line nitrogen oxides absorption column (F-8 Column)

Description: Large quantities of oxides of nitrogen (NO{sub x}) are routinely emitted from the F-Canyon dissolvers and from the F-Area A-Line denitrators. These gases are routed through a nitrogen oxides absorption column located in the A-Line. This column, referred to as the F-8 Column, removes NO{sub x} from the offgas, streams of the dissolvers and denitrators and generates nitric acid. The nitric acid is recycled to the canyon dissolvers. Because of continually more stringent environmental emission rest… more
