Evaluation of the Thermal-Hydraulic Operating Limits of HEU-LEU Transition Cores for the MIT Research Reactor
No full textThe MIT Research Reactor (MITR) is in the process of conducting a design study to
convert from High Enrichment Uranium (HEU) fuel to Low Enrichment Uranium (LEU)
fuel. The currently selected LEU fuel design contains 18 plates per element, compared to
the existing HEU design of 15 plates per element. A transitional conversion strategy,
which consists of replacing three HEU elements with fresh LEU fuel elements in each
fuel cycle, is proposed. The objective of this thesis is to analyze the thermo-hydraulic
safety margins and to determine the operating power limits of the MITR for each mixed
core configuration.
The analysis was performed using PLTEMP/ANL ver 3.5, a program developed
for thermo-hydraulic calculations of research reactors. Two correlations were used to
model the friction pressure drop and enhanced heat transfer of the finned fuel plates: the
Carnavos correlation for friction factor and heat transfer, and the Wong Correlation for
friction factor with a constant heat transfer enhancement factor of 1.9. With these
correlations, the minimum onset of nucleate boiling (ONB) margins of the hottest fuel
plates were evaluated in nine different core configurations, the HEU core, the LEU core
and seven mixed cores that consist of both HEU and LEU elements. The maximum radial
power peaking factors were assumed at 2.0 for HEU and 1.76 for LEU in all the analyzed
core configurations.
The calculated results indicate that the HEU fuel elements yielded lower ONB
margins than LEU fuel elements in all mixed core configurations. In addition to full
coolant channels, side channels next to the support plates that form side coolant channels were analyzed and found to be more limiting due to higher flow resistance. The
maximum operating powers during the HEU to LEU transition were determined by
maintaining the minimum ONB margin corresponding to the homogeneous HEU core at
6 MW. The recommended steady-state power is 5.8 MW for all transitional cores if the
maximum radial peaking is adjacent to a full coolant channel and 4.9 MW if the
maximum radial peaking is adjacent to a side coolant channel.United States. Dept. of Energy. Reduced Enrichment Research and Test Reactor Progra
The Contemporary Writer Hu Wan-ch'un
No full textThis brief paper is divided into the following three parts. 1. The place of the new writer Hu Wan-ch'un 胡萬春 in contemporary Chinese literature. 2. A description of the author's upbringing based on autobiographical materials. 3. A critique of his work. The first part makes clear Hu Wan-ch'un's position as a writer who emerged from among the industrial workers of present day Shanghai, in contrast to Chao Shu-Ii, the principal figure in contemporary Chinese literature, who comes from a peasant background. It also considers the relationship between Hu Wan-ch'un and other writers who deal with the theme of industrial production such as Chou Li-po, Ai Wu, and Ts'ao Ming. The second part presents a translation of the autobiographical materials on the author's life and explains the process of his ideological and literary growth. The third part discusses the author's works, concentrating in particular upon the literary effect produced by the fusion of emotional image and ideology in Hu Wan-ch'un's writings

The new species is similar in general appearance and tergites characters to N. congchaoi Hu & Li (Hu & Li 2015: 11, Fig. 6), but can be separated by the wider posterior excision of male sternite VIII, by the much shorter ventral process (Fig. 21) and much wider dorso-lateral apophyses of aedeagus (Fig. 21). Etymology. The specific epithet derived from Leigong Mt., where the species was discovered.Published as part of Lin, Xiao-Bin, Yu, De-Hui & Hu, Jia-Yao, 2022, The Nazeris fauna of the Leigong Mountain, Guizhou, China (Coleoptera, Staphylinidae, Paederinae), pp. 41-53 in Zootaxa 5138 (1) on pages 45-47, DOI: 10.11646/zootaxa.5138.1.4, http://zenodo.org/record/655213
