چکیده
This report describes our investigation of steam generator behavior during a postulated tube rupture accident. Our study was performed using the steam generator, thermal-hydraulic analysis code THERMIT-UTSG. The purpose of our work was to provide an independent assessment of the Los Alamos National Laboratory system code TRAC-PF1 with respect to steam generator tube rupture analysis. Results of our work are presented and compared with previous TRAC-PF1 results. There are substantial differences in the results of the two codes. These discrepancies are discussed and deficiencies in both codes are noted. Our results lead us to believe that further investigation and code development are necessary to gain more than a basic understanding of steam generator behavior during such accidents and to provide a simulation capability that is acceptable.

Analysis of genomic alterations in benign, atypical, and anaplastic meningiomas: toward a genetic model of meningioma progression.
Nineteen benign [World Health Organization (WHO) grade I; MI], 21 atypical (WHO grade II; MII), and 19 anaplastic (WHO grade III; MIII) sporadic meningiomas were screened for chromosomal imbalances by comparative genomic hybridization (CGH). These data were supplemented by molecular genetic analyses of selected chromosomal regions and genes. With increasing malignancy grade, a marked accumulati...
متن کاملAcquisition of Hormone-independent Growth in MCF-7 Cells Is Accompanied by Increased Expression of Estrogen-regulated Genes but Without Detectable DNA Amplifications
A hormone-independent but hormone-responsive subpopulation (MCF7/ Mil l ) of the hormone-dependent MCF-7 human breast cancer cell line (R. Clarke et al., Proc. Natl. Acad. Sci. USA 86: 3649-3653, 1989) was further passaged in ovariectomized nude mice and re-established in vitro as the continuous cell line MCF7/LCCI. The lag time to the appearance of proliferating tumors in ovariectomized animal...

متن کاملInfluence of anions on intervalence charge transfer (IVCT) in mixed-valence dinuclear complexes.
Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...
متن کاملDFT studies on the magnetic exchange across the cyanide bridge.
Exchange coupling across the cyanide bridge in a series of novel cyanometalate complexes with CuII-NC-MIII (M = Cr and low-spin Mn, Fe) fragments has been studied using the broken-symmetry DFT approach and an empirical model, which allows us to relate the exchange coupling constant with sigma-, pi-, and pi*-type spin densities of the CN- bridging ligand. Ferromagnetic exchange is found to be do...
