System codes description

It has been shown before that a number of plant situations can only be simulated with computer codes. 

The computer code development started together with the development of nuclear reactor systems. With increasing computer capabilities, a sound experimental basis and the set-up of validation matrices the computer code development for system codes has now practically reached its final stage. As examples, short descriptions for ATHLET, RELAP 5 and CATHARE are given below.

Note "Organic Chemicals" refers to HS (Harmonized Commodity Description and Coding System) Code 29. 

Note "Inorganic Chemicals" refers to "inorganic chemicals organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes," HS (Harmonized Commodity Description and Coding System) Code 28. 

Note "Photographic or Cinematographic Goods" refers to HS (Harmonized Commodity Description and Coding System) Code 37. Products in this classification include "photo plates and film, flat, sensitized, unexposed photo film in rolls sensitized, unexposed photo paper, paperboard and textiles, sens, unexposed photo plates, film, paper, etc, exposed, not developed photo plates and still film, exposed developed motion-picture film, exposed and developed photographic chemicals, unmixed products retail packed."... 

Select the one (most) direct cause and the root (basic) cause (the one for which corrective action will prevent recurrence and have the greatest, most widespread effect). In cause selection, focus on programmatic and system deficiencies and avoid simple excuses such as blaming the employee. Note that the root (basic) canse mnst be an explanation (the why) of the direct cause, not a repeat of the direct canse. In addition, a cause description is not just a repeat of the category code description it is a description specific to the occurrence. Also, up to three (contributing or indirect) causes may be selected. Describe the corrective actions selected to prevent recurrence, including the reason why they were selected, and how they will prevent recurrence. Collect additional information as necessary. 

This is obviously an oversimplified picture. To handle solidification properly, it is necessary to include an equation that describes the growth of a glassy or crystalline phase and a stress equation that accounts for the biphasic nature of the system. Such descriptions are the subject of recent research, and these results should be used in new simulation codes, especially for semicrystalline polymers, but the approximation of an instantaneous transition from a liquid to an undeformable solid at a fixed average temperature T = Tl captures the important features of the spinline and suffices for our purposes here. 

At the Delft University of Technology two thermohydraulic test facilities are being used to study the instability types in natural-circulation BWRs DESIRE for type-II oscillations and CIRCUS for type-I oscillations. A description of DESIRE is given in Section 2, a description of CIRCUS is given in Section 3. Both facilities can be used to produce valuable experimental data needed for further model development in the system codes applied for nuclear power plant analyses[5]. 

Using the federal system, the New Jersey Department of Labor assigns the classification code at the time that an employer registers his or her business with that department for unemployment insurance programs. The assignment is based on the employer s description of the primary activity of the business. 

As failure data relating to mechanical components differ widely from source to source, TNO has set up a documentation system in which all relevant information is stored in one, uniform automated code called COMPI, which uses a component description code for the following information system of... 

Computer applications allow for defining and managing several important nonclinical data types that are managed by the system itself. Such data are referred to as metadata or control data. These are information such as domain-specific descriptions, application conditions, parameters, and methods in a repository. Control data fields can be part of the data collection forms or in system-defined tables. Some of these control fields include electronic signatures, form status, transmission date, transmission number, field completed, and memo fields (large text format). The database contains tables for reference ranges, visit schedule, form schedule, labels, and drug codes.
