General design criteria

Designing plastic Basically the general design criteria applicable to plastics are the same as those for metals at elevated temperature that is, design is based on (1) a deformation limit, and (2) a stress limit (for stress-rupture failure). There are, of course, cases where weight is a limiting factor and other cases where short-term properties are important. 

Formulate a statement of the design criteria for the unit. What is the general design criteria What is the design (or the unit) intended to achieve For example, a reactor is usually required to achieve a particular conversion of reactants to products, a distillation column must provide a particular separation, an absorption column provides removal of a specific level of impurity, etc. 

The discovery of new therapeutic entities always initiates excitement, but the contributions of the formulation specialist are either not well understood or are often taken for granted and thus remain unsung. However, the drug and its delivery system cannot be separated. The general design criteria for tablets are given as follows ... 

Having discussed possible hydrogen supply systems and general design criteria, we now pose a series of "system-level" questions about transition to a hydrogen energy system. 

The general design criteria here cover standard design H-w Height of outlet weir... 

Regulation No. 195 sets requirements pertinent to the design of systems important to safety. These requirements are of rather general nature comparable e.g. to the US NRC General Design Criteria. The... 

DOE 6430,1 A, GENERAL DESIGN CRITERIA, which provides useful practices and guidance for design of non-reactor facilities. 

Code of Federal Regulations, Title 10, Part 50, Appendix A, "General Design Criteria for Nuclear Power Plants, " which establishes minimum general design criteria for NRC licensed light water nuclear power pI ants. 

Portions of this Order recommend industry codes and ANSI standards and the applicable portions of 10 CFR Part 50 including the General Design Criteria in 10 CFR Part 50 Appendix A. 

The first collection of internationally accepted safety criteria is given in the General design criteria for nuclear plants (see Appendix 8). They consist of 52 criteria and were written at the beginning of the 1970s. They are still used today with some additions to keep them up to date. The GDC are regulatory criteria, that is they have been established by the central national institutions in order to protect the population. 

The IAEA document concerning the General Design Criteria Safety of nuclear power plants Design requirements , was published in 2000 (see www. iaea.org). The IAEA documents of regulatory interest are divided into the following categories ... 

Appendix 3 lists the contents of some other compilations of general design criteria, where EUR, GDC, OPB 88/97 and PUN are compared with the content of IAEA criteria. 

ENEA/DISP, Criteri Generali di Progetto per Centrali Nucleari di Tipo ad Acqua Leggera in Pressione (General Design Criteria for Pressurized Light Water Nuclear Power Plants), Roma, Italy, 1987, Doc.DISP(87)10. 

This table is intended to serve as a memo for the content of five of the general design criteria for nuclear plants, thought to be rather representative of the overall picture. The first column of the table contains the complete list of the IAEA criteria, which are rather recent and therefore complete. If another criteria has no... 

US general design criteria The following text is reproduced from the US (1971) The criteria document numbering and cross- General Design Criteria (CFR Part 50, App. A) , references have been retained. ... 

The development of these General Design Criteria is not yet complete. For example, some of the definitions need further amplification. Also, some of the specific design requirements for structures, systems, and components important to safety have not as yet been suitably defined. Their omission does not relieve any applicant from considering these matters in the design of a specific facility and satisfying the necessary safety requirements. These matters include ... 

There will be some water-cooled nuclear power plants for which the General Design Criteria are not sufficient and for which additional criteria must be identified and satisfied in the interest of public safety. In particular, it is expected that additional or different criteria will be needed to take into account unusual sites and environmental conditions, and for water-cooled nuclear power units of advanced design. Also, there may be water-cooled nuclear power units for which fulfillment of some of the General Design Criteria may not be necessary or appropriate. For plants such as these, departures from the General Design Criteria must be identified and justified. 

The initiating events (which in general descend from the general design criteria), usually subdivided in a certain number (often four) operation conditions. 

B. Specific criteria necessary to meet the relevant requirements of General Design Criteria 41, 42, and 43 include ... 

The general design criteria for tank containers with respect to safe handling, stacking and transport can be complied with if the structural equipment (frame) is designed in accordance with ISO 1496-3 [9]. This standard prescribes a structural...
