对核设施退役环境安全问题的讨论

在初步学习ICRP第82号出版物的基础上,讨论了长寿命放射性残存物所致可控持续照射的防护原则及其在核设施退役中的应用。涉及不同来源残存物的清除或补救,如何针对不同情况实施实践或干预的原则,以及退役终态目标的选择等问题。     

我国核电对国民剂量的贡献

估算了我国核电生产对国民剂量的贡献 ,只占相同电能煤电生产所致国民剂量的 5 .2 1 % ,核电替代相同电能的煤电可使国民剂量减少 81 .86人· Sv。     

Propagation of Surface Wave Along a Thin Plasma Column and Its Radiation Pattern

Propagation of the surface waves along a two-dimensional plasma column and the far-field radiation patterns are studied in thin column approximation. Wave phase and attenuation coefficients are calculated for various plasma parameters. The radiation patterns are shown. Results show that the radiation patterns are controllable by flexibly changing the plasma length and other parameters in comparison to the metal monopole antenna. It is meaningful and instructional for the optimization of the plasma antenna design.     

装饰建材放射性无损检测及评价方法研究

根据γ衰变纲图，研究将γ射线强度的测量问题转化为表面α射线的强度测量问题，从而实现建材的快速无损检测。进行了各类建材表面α、β辐射水平和其天然放射性核素γ比活度关系的研究和不同饰材表面β辐射水平的饱和厚度研究。结果发现：由于天然放射系中最大能量β粒子的射程大于单块饰材，不能用表面β辐射水平进行无损检测判断；花岗石的表面α辐射水平与外照射指数的拟合关系为：Iγ=0．38 49．84α 288．24α^2，拟合曲线和实测值的符合率为95％；抛光砖的表面α辐射水平与外照射指数的拟合关系为：Iγ=0．42 343．55α-32999．66α^2，拟合曲线和实测值的符合率为90％。积累更多的数据将进一步提高拟合曲线和实测值的符合率。     

Impurity behaviour,radiation losses and wall effects in the T.F.R. machine

Spectroscopic, bolometric, soft X-rays and electrical measurements have been performed on T.F.R. up to 400 kA-60 kG. Light impurities appear very early. They are recycling in a stationary state during the current plateau. The heavy impurities density grows during the current rise, then levels off or increases slightly during the current plateau. The production of fast electrons is evaluated. Densities and fluxes of impurities are given. Photodesorption, photoelectron induced desorption, ion desorption, thermal desorption, evaporation and sputtering are discussed as possible candidates for the pollution.     

Temperature of the Limiter Surface Measured by IR Camera in HT-7 Tokamak

Temperature measurement by IR （infrared） camera was performed oll HT-T tokamak. particularly during long pulse discharges, during which the temperature of the hot spots on the belt limiter exceeded 1000℃. The heat load on the surface of the movable limiter could be obtained through ANSYS with the temperature measured by IR-camera. This work could be important for the temperature measurement and heat load study on the first wall of EAST device.     

不同类型事故受照人员生物剂量估算和辐射影响评价

结合近年来发生的数起不同类型的辐射事故,对指导临床救治的生物剂量估算过程进行报道,特别针对辐射生物剂量学的难点问题,如迁延照射、大剂量照射及快速剂量估算等瓶颈问题,采取不同手段和方法给予解决,并对辐射远后效应做出评价。     

对计划照射中个人剂量约束的理解

基于对计划照射中个人剂量约束概念的理解,讨论了个人剂量约束在公众照射和职业照射中的应用。在计划照射情况下,公众照射的剂量约束值通常由国家监管机构建立或批准;对于职业照射,鼓励在核能行业组织和核能集团内建立职业照射个人剂量约束值,比审管部门规定具体的约束值可能更合适。     

核与辐射事故后管理策略的发展现状
