Reliability acceptable

The functional attributes that permits its growth at an accelerated rate are reliability, acceptability, feasibility and economics. Field installations of the new products are now providing more of the necessary reliable long time data. The field tests continue to be the best approach in demonstrating acceptance. 

High reliability, acceptable capital and operating costs, and minimal environmental impact are requirements for gasification systems proposed for utility applications. Operating costs can be minimized by using a gasifier that is... 

Summarizing, since the basis-set superposition error may be large (that is, comparable to the interaction energy) and since it depends in an erratic way upon basis set and geometry, and affects both Cl and SCF calculations and is extremely difficult to avoid without reducing the quality of the calculation, it is of vital importance to arrive at a reliable accepted scheme to correct for it. 

Although the metal-carbon bond in cyano compounds has been confirmed by neutron diffraction in only a limited number of substances (24—29), it is generally and reliably accepted that in the stable mononuclear complexes the metal is always bonded to carbon. Support for the M—C—N linkage is provided by electronic spectra (30) and by vibrational spectroscopic data obtained with different isotopes (31).

To minimize technology development risk, the INEL has focused on LWR concepts similar to those in the commercial industry. This technology is considered to be the most mature and well established. In addition, LWRs are reliable, accepted, and licensable. A new concept has the best chance of being designed and constructed quickly and economically if it is based on LWR technology. Furthermore, nuclear facility management and operational infrastructures are well established.

The mathematical requirements for unique determination of the two slopes mi and ni2 are satisfied by these two measurements, provided that the second equation is not a linear combination of the first. In practice, however, because of experimental error, this is a minimum requirement and may be expected to yield the least reliable solution set for the system, just as establishing the slope of a straight line through the origin by one experimental point may be expected to yield the least reliable slope, inferior in this respect to the slope obtained from 2, 3, or p experimental points. In univariate problems, accepted practice dictates that we... 

Considerable effort has been directed to determining the causes of connection failutes and to learning how to minimize the likelihood of occurrence. Acceptable failute rates range from <1 in 10 operating hours for contacts in air-frame (31) electrical systems and in some telecommunications equipment, to 100—1000 in 10 operating hours in instmments, to even larger rates for contacts in many consumer products. A failute is defined as exceedance of contact resistance, which can be as Httle as twice the initial contact resistance, that causes circuit malfunction. The required lifetimes of connectors may be >20 yr, although most required appHcation times ate shorter (see Materials reliability). 

Despite being simple, rugged, reliable, requiring low maintenance, low cost, and vibration free, steam-jet systems are not widely accepted in water chilling for air-conditioning due to characteristics of the cycle,... 

The evaluation of metrological characteristics of the technique, perfonued with minerals of different composition, showed that technique developed for reliability and precision satisfies the requirements offered for quantitative determinations, category II. The detection limits are acceptable for solving the problems posed and amount to 0.1 - 0.4 wt. %, depending on the element analyzed. 

Having previously introduced the key methods to determine the important variables with respect to stress and strength distributions, the most acceptable way to predict mechanical component reliability is by applying SSI theory (Dhillon, 1980). SSI analysis is one of the oldest methods to assess structural reliability, and is the most commonly used method because of its simplicity, ease and economy (Murty and Naikan, 1997 Sundararajan and Witt, 1995). It is a practical engineering tool used for quantitatively predicting the reliability of mechanical components subjected to mechanical loading (Sadlon, 1993) and has been described as a simulative model of failure (Dasgupta and Pecht, 1991).

The advantages of static sampling systems are their portability, convenience, reliability, and low cost. The systems are lightweight and can be attached directly to individuals. Nonstatic sampling systems can, of course, also be attached to individuals, but are less convenient because the person must carry a battery-powered pump and its batteries. Static sampling systems are very reliable, and the materials used limit the costs to acceptable levels. 

While there had been concern about the reliability of computer systems, they are currently receiving wide acceptance and are fast replacing analog systems. 

The major problems arise from accepting an instrument reading as reliable without determining its calibration and the reproducibility of its response and in not obtaining representative tests. Plant personnel must have some experience with and knowledge of the resolution of these problems. 

Backup systems which depend upon the action of automatic cut-in devices (e.g., a turbine-driven standby spare for a motor-driven cooling water pump, with PLCI control) would not be considered an acceptable means of preventing a utility failure for normal pressure relief design purposes, even though their installation is fully justified by improved continuity and reliability of plant operations. 

In general, vacuum vents and inert or gas repressuring systems are not considered an acceptable alternative to vacuum design for process equipment. Repressuring systems may be provided for process reasons, but they are not considered sufficiently reliable for equipment protection. Vacuum breakers are difficult to maintain tight and may admit air into the equipment.
