The non-fuel part size can affect the FCMTM temperature and stress distribution greatly by changing the distance between tristructural isotropic (TRISO) particles. The maximum temperature of SiC matrix increased from 1220 K to 1450 K with the non-fuel part size increasing from 100 \u03bcm to 500 \u03bcm, and the matrix temperature of all the samples was lower than the decomposition point of SiC ceramics. The maximum hoop stress decreased with non-fuel part size, but the inner part exhibiteda crosscurrent trend. The inner part of the SiC matrix lost structure integrity because of the large hoop stress caused by the deformation of TRISO particles, however, the non-fuel parts of FCMTM pellet may maintain their integrity when the non-fuel part size was larger than 300 \u03bcm. SiC layers hoop stress increased with non-fuel part size, and the failure probability of SiC layer was lower than 2.2 \u00d7 10\u22124 for the FCMTM pellet with small non-fuel part size. The integrity of non-fuel and SiC layers can be maintained for the FCMTM pellet with the non-fuel part size from 300 \u03bcm to 400 \u03bcm.<\/jats:p>","DOI":"10.3390\/computation8010013","type":"journal-article","created":{"date-parts":[[2020,2,21]],"date-time":"2020-02-21T10:49:16Z","timestamp":1582282156000},"page":"13","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effect of Structure on the Thermal-Mechanical Performance of Fully Ceramic Microencapsulated Fuel"],"prefix":"10.3390","volume":"8","author":[{"given":"Yi","family":"Zhou","sequence":"first","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhong","family":"Xiao","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shichao","family":"Liu","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Chen","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hua","family":"Pang","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Xin","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongjun","family":"Jiao","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shixin","family":"Gao","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjie","family":"Li","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junchong","family":"Yu","sequence":"additional","affiliation":[{"name":"Nuclear Power Institute of China, Science and Technology on Reactor System Design Technology Laboratory, Chengdu 610200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,21]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Fully Ceramic Microencapsulated Fuels: A Transformational technology for Present and Next Generation Reactors-Properties and Fabrication of FCM Fuel","volume":"104","author":"Snead","year":"2011","journal-title":"Trans.
