In this study,\ncharacteristics of HTR-10, Tsinghua University research reactor, are\nused and not only double heterogeneous but also truncated CFPs and\nPebbles are considered.Firstly, 8335 CFPs are distributed randomly\nin a pebble and then the core of reactor is filled with those pebbles\nand graphite pebbles as moderator such that 57:43 ratio of fuel and\nmoderator pebbles is established.Finally, four different core\nconfigurations are modeled. They are Simple Cubic (SC) structure\nwith truncated pebbles,SC structure without truncated pebble, and\nSimple Hexagonal(SH) structure without truncated pebbles and SH\nstructure with truncated pebbles. Results like effective multiplication\nfactor (Keff), critical height,etc. are compared with available data.", "identifier": "https://doi.org/10.5281/zenodo.1061906", "inLanguage": {"@type": "Language", "alternateName": "eng", "name": "English"}, "keywords": "Double Heterogeneity, HTR-10, MCNP, Pebble Bed Reactor, Stochastic Geometry.", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "name": "An Exact MCNP Modeling of Pebble Bed Reactors", "publisher": {"@type": "Organization", "name": "Zenodo"}, "size": "513.75 KB", "url": "https://zenodo.org/records/1061906", "version": "5901"}</script> <script src="/static/dist/js/invenio-app-rdm-landing-page-theme.4af2a981b6a30d597c91.js"></script> <script src="/static/dist/js/9945.a03f1f6dc49a48e9f324.js"></script> <script src="/static/dist/js/1357.0f990cc992d33940680e.js"></script> <script src="/static/dist/js/1644.8f60469b96df124a0180.js"></script> <script src="/static/dist/js/8962.1233fea20bc7af86336e.js"></script> <script src="/static/dist/js/9300.4f9a5586a957a5004257.js"></script> <script src="/static/dist/js/5680.17cf540b6e4aeb8e91c7.js"></script> <script src="/static/dist/js/invenio-app-rdm-landing-page.ef6dd12ca828fb095757.js"></script> <script src="/static/dist/js/previewer_theme.3d454e64a192d672e854.js"></script> <script src="/static/dist/js/zenodo-rdm-citations.c20ea4f4ccb963a0648e.js"></script> <div class="ui container info message cookie-banner hidden"> <i class="close icon"></i> <div> <i aria-hidden="true" class="info icon"></i> <p class="inline">This site uses cookies.
