Applicable design requirements

The Safety Requirements publication on Safety of Nuclear Power Plants Design [1] establishes requirements in paras 4.2 and 4.4  

In relation to the concept of defence in depth. Ref. [1] (para. 2.11) also

System design uses a top-down approach with an appropriate level of design specifications to detail how the system hardware and software will be built to meet the application design requirements defined by the FDS. 

For other types of power conversion systems, equivalent alternative information should be provided to demonstrate the systems compliance with the applicable design requirements. 

Economics It is ironic that a great virtue of membranes, their versatility, makes economic optimization of a membrane process veiy difficult. Designs can be tailored to veiy specific applications, but each design requires a sophisticated computer program to optimize its costs. Spillman [in Noble and Stern (eds)., op. cit., pp. 589-667] provides an overall review and numerous specific examples including circa 1989 economics. 

Certain facets of squeeze film dampers should be thoroughly understood to properly select the specific design required for a given application. Highlighting the theory of squeeze film dampers is helpful in dlls regard. 

Commercially available thermal oxidizer systems are pre-engineered, that is, the equipment is designed on the principle that in order for the equipment to be competitive in the marketplace, then a series of products of fundamentally standard designs are tailored to the application by changing some of the parameters as dictated by the requirements. This is not always the case with other pollution control systems, as oftentimes custom built-systems are specified. Since thermal oxidation equipment has a burner, the designs require controls for safety and operation. 

The process of selecting the appropriate combination of fibers and matrix material for a particular application is rather involved. The imposed design requirements will aid in eliminating from consideration certain matrix materials or fibers or combinations thereof. Flowever, some combinations of constituent materials are not so obviously evaluated. 

The first step in the design of a lighting system is the determination of the various lighting levels required for the specific areas of the facility. Typically, the majority of the fixtures are high intensity discharge (HID) fixtures and fluorescent fixtures. Certain applications may require incandescent fixtures as well. 

It is important for the designer to become familiar with all the information that is available for each plastic, especially that which is pertinent to the product design requirements. Designers, who are knowledgeable of the data derived from metal tests, could have a tendency to apply the plastic data sheet information in a manner similar to that used for metals. This could be understood because there is no warning that some of the data supplied by the manufacturer are applicable only when use and test conditions are nearly the same. 

If one is to consider the application of these data to a design, the size of the force and its rate of application would have to be obtained and compared with the design requirement. The breakdown of energy into components... 

All the mechanical properties described in tests for the conventional data sheet properties represented values of short-term application of forces, and, in most cases, the data obtained from such tests are used for comparative evaluation or as controlling specifications for quality determination of materials along with short-duration and intermittent-use design requirements. 

Spray 0.1 ohm per square foot hard, dense coating. mechanical bonding to plastic special applications equipment required requires special applicator safety procedures for dust and fumes warps thermoplastics not suitable for thin-walled designs not field repairable. 

Plants are selected according to application needs and the contaminants concerned. For phytodegradation of organics, the design requirements are that vegetation is fast growing and hardy, easy...
