| 1 | ^(235)U enrichment detection system for nuclear fuel rod based on compact D–D neutron generator显示文摘A reliable ^(235)U enrichment uniformity detection system based on a compact D–D neutron generator is developed to detect the ^(235)U enrichment uniformity of different fuel elements in the same nuclear fuel rod. The high-yield compact D–D neutron generator provides 2.45 MeV D–D neutrons, decelerated by a moderator to thermal neutrons or epithermal neutrons, thereby inducing ^(235)U fission to produce highly excited state fission fragments that undergo de-excitation via γ-ray emission. The system detects the ^(235)U enrichment uniformity of a nuclear fuel rod by measuring γ-rays and establishing a relationship between the γ-ray count rate and ^(235)U enrichment in nuclear fuel. The proposed system yields a confidence probability of 99.99% for a relative ^(235)U enrichment deviation of 10% and a neutron yield of 5 × 10^(8) n/s, and the detection accuracy increases with increasing neutron yield. Furthermore, the developed system can satisfy quality control requirements for nuclear fuel production to promote the safe development of nuclear power. | WU Kang LIU XingYu YANG Xu LIU ChangQi HUO DongYing BAI XiaoHou HAN Chao JIANG QiaoYue ZHANG Hang PENG JinQiu ZHANG Yu WANG JunRun YAO ZeEn WEI Zheng | 2021 | Science China(Technological Sciences)2021，64，9： | 1 |
| 2 | Reversible lithium storage in sp^(2) hydrocarbon frameworks显示文摘Polymer materials offer controllable structure-dependent performances in separation,catalysis and drug release.Their molecular structures can be precisely tailored to accept Li^(+)for energy storage applications.Here the design of sp^(2)carbon-based polyphenylene(PPH)with high lithium-ion uptakes and long-term stability is reported.Linear-PPH(L-PPH)exceeds the performance of crosslink-PPH(C-PPH),due to the fact that it has an ordered lamellar structure,promoting the Li^(+)intercalation/deintercalation channel.The L-PPH cell shows a clear charge and discharge plateau at 0.35 and 0.15 V vs.Li^(+)/Li,respectively,which is absent in the C-PPH cell.The Li^(+)storage capacity of L-PPH is five times that of the C-PPH.The reversible storage capacity is further improved to 261 m Ah g;by functionalizing the L-PPH with the–SO_(3)H groups.In addition,the Li-intercalated structures of C-PPH and L-PPH are investigated via near-edge X-ray absorption fine structure(NEXAFS),suggesting the high reversible Li^(+)–C=C bond interaction at L-PPH.This strategy,based on new insight into sp^(2)functional groups,is the first step toward a molecular understanding of the structure storage-capacity relationship in sp^(2)carbon-based polymer. | Zhangxiang Hao Junrun Feng Yiyun Liu Liqun Kang Bolun Wang Junwen Gu Lin Sheng Ruoyu Xu Sushila Marlow Dan J.L.Brett Yunhui Huang Feng Ryan Wang | 2022 | Journal of Energy Chemistry2022，31，3： | 0 |
