The NPRDS is an industry-wide system for monitoring the performance of selected systems and components at U.S. commercial nuclear power plants. Information in NPRDS is derived from a standardized format input report prepared by U.S. nuclear plant licensees. The plants are as)ced to submit failure reports on catastrophic events and degraded failures within the defined reportable scope reporting of incipient events is optional. Command faults are not reportable unless they malce an entire system unavailable. In addition, the plants are as)ced to file component engineering reports on all components within the selected systems and reportable scope. These reports contain detailed design data, operating characteristics, and performance data on the selected systems and components (over 3000 components, from approximately 30 systems, per unit). The selected systems are primarily safety systems. [Pg.64]

Quite recently, the arsenal of methods for aryl chlorides in the Mizoroki-Heck reaction was broadened by using the cheaper complex (Cy3P)2PdCl2 with CS2CO3 as the base in 1,4-dioxane at 120 °C [134]. The reported scope of substrates is broad, involving several nonstandard alkenes and many aryl chlorides electron-rich aryl chlorides, except for 4-chlorotoluene and sterically hindered couphng partners, were excluded in this study. [Pg.78]

Z. Zhang reported the synthesis and application of electron-rich MOP-type ligands in a comprehensive study [112]. The reported scope of these binaphthyl-based ligands is quite impressive, and matches those observed for of the biphenyl analogues. Nevertheless, their synthesis starting from BINOL includes several demanding synthetic transformations. [Pg.80]

The reported scope of the phenomenon is continuously expanding, as new examples of stereoselectively interacting selector/selectand pairs of known or yet unknown types are being found. It should be mentioned that modern, highly efficient columns allow chiral differentiation to be detected with certainty, even where the effects are very small and the resolution factors are close to unity. [Pg.291]

In addition to the procedures provided by standards organizations, it is advisable for metals producers to meiintain internal procedures manuals. Pertinent information may include deteiils regarding specimen heat treatment or preparation, location and type of equipment and materials to be used, specific user test requirements, report scope and format, along with disposition of records following testing. [Pg.777]

A report on sump water removal capability was issued jointly by the Savannah River Laboratory (SRL) and Idaho National Engineering L aboratory (INEL), and Sandia National Laboratory. The report scope includes calculations on flow to the minus 40-ft level during credible break size LOCAs to prove the existing sump pump capacity will remove ECS flow to the minus 40-ft level and to show that loss of pumping accidents are tolerable for small break LOCAs. This report, issued September 25, 1990, identifies the worst case LOCA as a Process Water pump suction bellows failure in loop 6 with four ECS injection paths (Reference 1). This report does not consider ECS throttling therefore, this LOCA condition will cause an eventual flooding of the DC motors. [Pg.279]

In a second attempt to extend the scope of Lewis-acid catalysis of Diels-Alder reactions in water, we have used the Mannich reaction to convert a ketone-activated monodentate dienophile into a potentially chelating p-amino ketone. The Mannich reaction seemed ideally suited for the purpose of introducing a second coordination site on a temporary basis. This reaction adds a strongly Lewis-basic amino functionality on a position p to the ketone. Moreover, the Mannich reaction is usually a reversible process, which should allow removal of the auxiliary after the reaction. Furthermore, the reaction is compatible with the use of an aqueous medium. Some Mannich reactions have even been reported to benefit from the use of water ". Finally, Lewis-acid catalysis of Mannich-type reactions in mixtures of organic solvents and water has been reported ". Hence, if both addition of the auxiliary and the subsequent Diels-Alder reaction benefit from Lewis-acid catalysis, the possibility arises of merging these steps into a one-pot procedure. [Pg.114]

Careful examination of literature reporting Lewis-acid catalysis of Diels-Alder reactions in combination with kinetic investigations indicate that bidentate (or multidentate) reactants are required in order to ensure efficient catalysis in water. Moreover, studies of a number of model dienophiles revealed that a potentially chelating character is not a guarantee for coordination and subsequent catalysis. Consequently extension of the scope in this direction does not seem feasible. [Pg.119]

The first report of oxidative carbonylation is the reaction of alkenes with CO in benzene in the presence of PdCh to afford the /3-chloroacyl chloride 224[12,206]. The oxidative carbonylation of alkene in alcohol gives the q, f3-unsaturated ester 225 and /3-alkoxy ester 226 by monocarbonylation, and succinate 111 by dicarbonylation depending on the reaction conditions[207-209]. The scope of the reaction has been studied[210]. Succinate formation takes... [Pg.51]

Within the scope of the original definition, a very wide variety of ionomers can be obtained by the introduction of acidic groups at molar concentrations below 10% into the important addition polymer families, followed by partial neutralization with metal cations or amines. Extensive studies have been reported, and useful reviews of the polymers have appeared (3—8). Despite the broad scope of the field and the unusual property combinations obtainable, commercial exploitation has been confined mainly to the original family based on ethylene copolymers. The reasons for this situation have been discussed (9). Within certain industries, such as flexible packaging, the word ionomer is understood to mean a copolymer of ethylene with methacrylic or acryhc acid, partly neutralized with sodium or zinc. [Pg.404]

The standard does not address product recall other than in the context of releasing product for urgent production purposes in clause 4.10.2.3. The reported nonconformities from your customers may be so severe that you need to recall product, not just one or two but a whole batch or several batches between two dates or serial numbers. Product recall can be considered to fall within the scope of handling reported nonconformities ... [Pg.455]

In 1934, French chemist Hoch reported that the action of phenylmagnesium bromide on the oxime of propiophenone (3) at elevated temperature gave two products. One was aziridine 4 and the other was erroneously assigned as hydroxylamine 5. In the subsequent years (1939 onward), Campbell at the University of Notre Dame determined that the purported hydroxylamine 5 was actually P-hydroxylamine 6. The scope of the Grignard reagents was extended to both aryl and aliphatic Grignard reagents. [Pg.22]

In 1974, Gassman et al. reported a general method for the synthesis of indoles. For example, aniline 5 was reacted sequentially with r-BuOCl, methylthio-2-propanone 6 and triethylamine to yield methylthioindole 7 in 69% yield. The Raney-nickel mediated desulfurization of 7 then provided 2-methylindole 8 in 79% yield. The scope and mechanism of the process were discussed in the same report by Gassman and coworkers as well. [Pg.128]
