Criteria for Transport

According to IAEA Safety Standards [220], a safe container for the transport of nuclear fuel is defined in the following way. Paragraph 656 [220] states that a delivery must be constructed according to the following rules  

Nuclide Calculated activity values after 2.5 years. 30 fuel assemblies with 4.4% enrichment and a bum-up of 50 MWd/kg U Aj (Bq/container) A2i according to [220] (Bq) Rate Ai A2i 

627(c), if the delivery has a maximum weight of 500 kg, a total density is determined on the base of outward sizes at the maximum of 1000 kg m and the radioactive content is more than 1000 2, but it is not radioactive material of special type, or  

627(a) an accumulated loss of the radioactive content is limited during one week to a maximum of 10A2 in the case of Kr and a maximum A2 for the rest of the nuclides. In the case of a mixture of radionuclides we have to apply paragraphs 304-306 except for Kr, where it is possible to use the effective value 2 = 100 TBq (2000 Ci). 

Releasable activities from the C-30 loaded with fuel were calculated at the NPP Research Instimte at Trnava, and they are listed for 30 fuel assemblies in Table 4.30.

Risk criteria have been established by some regulatory agencies and companies for fixed-facility risks however, there are very limited such target criteria for transportation risks, with a few companies beginning to use criteria for transportation risks. Where criteria are employed, initial risk estimates are compared against the criteria. If the risk target level is not met or is exceeded, the addition of risk reduction measures to reduce the risk estimate to (or below) the target risk level is evaluated. 

The Computer Sciences Division at the Oak Ridge National Laboratory has undertaken a program to evaluate the criticality criteria for transport packaging of fissionable materials as expressed in Title 10 of the Code of Federal Regulations Part 71. The study is focused presently on the definition of criticality, for, water-reflected arrays of loaded cbiitainers as a function of container volume, type of insulating material and its thickness, and the number of packages., ...

Liquid cycloahphatic amines and diamines have exacting purity and color standards. Almost all are sold to specification, not performance standards. Use as isocyanate precursors requites low water content criteria for these hygroscopic fluids, hence nitrogen blanketing is often specified for product sampling as well as storage and transport.

The purpose of a scoping analysis is to determine, under worst case assumptions, if there is a risk that can cause injury, death or financial impact to the public, workers, company, or environment. The PSA begins by identifying the hazards, their physical and chemical properties, the confinement, conditions and distance for transport to a target, estimating the effects on the target, and comparing these effects with accepted criteria.

The emulsion must be separated by the addition of chemical demulsifiers before the crude oil can be accepted for transportation. The quality criteria for a delivered crude oil are the residual salt content and the water content. For the oil to have a pipeline quality, it is necessary to reduce the water content to less than approximately 1.0%. 

The general criteria for an experimental investigation of the kinetics of reactions at liquid-liquid interfaces may be summarized as follows known interfacial area and well-defined interfacial contact are essential controlled, variable, and calculable mass transport rates are required to allow the transport and interfacial kinetic contributions to the overall rate to be quantified direct interfacial contact is preferred, since the use of a membrane to support the interface adds further resistances to the overall rate of the reaction [14,15] a renewable interface is useful, as the accumulation of products at the interface is possible. Finally, direct measurements of reactive fluxes at the interface of interest are desirable.

The criteria for good electron transport materials are that they should transport electrons, block holes, and have a small barrier to electron injection from the metal cathode. The most commonly used ETL in vacuum-deposited OLEDs is tris-(8-hydroxyquinoline) aluminum (Alq3), as shown in Figure 7.7. Alq3 for example, has a LUMO energy level of 3 eV [65] and an electron mobility of 5x 10 5 cm2/(V s) [66]. 

Reviewing the criteria for inclusion of components into the electron transport chain, Slater (1958) highlighted considerations previously advanced by H.A. Krebs as necessary to establish a pathway, namely that the amounts of enzyme present must be commensurate with enzymic activity in the preparation, activity should be fully restored by the reintroduction of the postulated component into an inhibited or depleted preparation, and that the rates of oxidation and reduction of components must be at least as great as those in the system overall. Reduction of cytochrome b by the systems then in use was thought by Chance (1952) and Slater (1958) to be too slow for the inclusion of this cytochrome into the main chain.
