    • 摘要: 【国际热核聚变实验堆组织网站2022年3月1日报道】法国核安全局(ASN)近日下令停止国际热核聚变实验堆(ITER)设备组装,直至多个安全问题得到解决。核安全局2012年批准ITER设计,并准许ITER组织(ITER Organization)在卡达拉奇(Cadarache)启动ITER建设工作。作为一项正常的监管工作,核安全局在ITER建设过程设置了若干“停工待检点”。在这些“停工待检点”,ITER组织必须证明安全相关厂房、土木结构件、系统和设备均能满足设计要求;只有得到核安全局的许可,建设工作才能继续推进。

    • 摘要: In this study,the effects of changing first wall materials and their thicknesses on a reactor were investigated to determine the displacement per atom(DPA)and gas production(helium and hydrogen)in the first wall,as well as the tritium breeding ratio(TBR)in the coolant and tritium breeding zones.Therefore,the modeling of the magnetic fusion reactor was determined based on the blanket parameters of the International Thermonuclear Experimental Reactor(ITER).Stainless steel(SS 316 LNIG),Oxide Dispersion Strengthened Steel alloy(PM2000 ODS),and China low-activation martensitic steel(CLAM)were used as the first wall(FW)materials.Fluoride family molten salt materials(FLiBe,FLiNaBe,FLiPb)and lithium oxide(LiO_(2))were considered the coolant and tritium production material in the blanket,respectively.Neutron transport calculations were performed using the wellknown 3D code MCNP5 using the continuous-energy Monte Carlo method.The built-in continuous energy nuclear and atomic data libraries along with the Evaluated Nuclear Data file(ENDF)system(ENDF/B-V and ENDF/B-VI)were used.Additionally,the activity cross-section data library CLAW-IV was used to evaluate both the DPA values and gas production of the first wall(FW)materials.An interface computer program written in the FORTRAN 90 language to evaluate the MCNP5 outputs was developed for the fusion reactor blanket.The results indicated that the best TBR value was obtained for the use of the FLiPb coolant,whereas depending on the thickness,the first wall replacement period in terms of radiation damage to all materials was between 6 and 11 years.

    • 摘要: 对管道连接装配型ITER增强热负荷第一壁(EHF FW)的标准手指对、边缘手指对及中心梁(CB)开展了热工水力分析。分析结果显示流速分布合理,低于1m·s^(-1)或高于10m·s^(-1)的区域非常小;手指对间的流量分配较合理;整个第一壁的压降为0.351MPa,小于0.4MPa的限定值;在8个循环周期内CB最高温度为409.21°C,低于450°C的允许值;而边缘手指铠甲上尖角区域最高温度为846.54°C,需高热负荷实验来验证其安全性。

    • 摘要: 通过焊接和“整体环形锻造+线切割”两种制造方案对ITER磁体支撑U型支撑夹(PFCS2 U)的制造进行了研究。在采用TIG焊接方案时,通过对组件进行双面和单面焊接,结合多种辅助工装和热处理,最终可将尺寸控制在要求范围内,77K时焊缝的夏比冲击性能低于100J;在采用“整体环形锻造+狭缝线切割”的制造方案时,U型支撑夹的开口尺寸和狭缝尺寸均满足公差要求,同时保证了U型支撑夹的材料性能的一致性,提高了U型支撑夹的力学性能。“整体环形锻造+狭缝线切割”最终获得ITER国际组织(IO)的认可,并应用到U型支撑夹的批量生产中。

    • 摘要: 国际热核聚变实验堆(ITER)是目前全球规模最大、影响最深远的国际科研合作项目之一。国际热核聚变实验堆装置是一个能产生大规模核聚变反应的超导托卡马克,俗称“人造太阳”。下杜瓦冷屏(Lower Cryostat Thermal Shield)是托卡马克杜瓦装置安装的第一个冷屏系统,其作用是在杜瓦底座、真空室等高温部件与超导磁体间建立冷保护屏障。下杜瓦冷屏具有直径大、预组装精度要求高、吊装就位过程间隙小等特点,这些特点对下杜瓦冷屏的预组装与吊装工作提出了非常高的要求。本文结合现场施工过程的实际情况,论述了通过激光跟踪测量以及偏差雷达图确保预组装精度的方法,通过水平度调节以及导向工装安装以保障下杜瓦冷屏吊装安全及精准就位的方法。

    • 摘要: India has proposed the helium-cooled solid breeder blanket concept as a tritium breeding module to be tested in ITER.The module has lithium titanate for tritium breeding and beryllium for neutron multiplication.Beryllium also enhances tritium breeding.A design for the module is prepared for detailed analysis.Neutronic analysis is performed to assess the tritium breeding rate,neutron distribution,and heat distribution in the module.The tritium production distribution in submodules is evaluated to support the tritium transport analysis.The tritium breeding density in the radial direction of the module is also assessed for further optimization of the design.The heat deposition profile of the entire module is generated to support the heat removal circuit design.The estimated neutron spectrum in the radial direction also provides a more in-depth picture of the nuclear interactions inside the material zones.The total tritium produced in the HCSB module is around 13.87 mg per full day of operation of ITER,considering the 400 s ON time and 1400 s dwell time.The estimated nuclear heat load on the entire module is around 474 kW,which will be removed by the high-pressure helium cooling circuit.The heat deposition in the test blanket model(TBM)is huge(around 9 GJ)for an entire day of operation of ITER,which demonstrates the scale of power that can be produced through a fusion reactor blanket.As per the Brayton cycle,it is equivalent to 3.6 GJ of electrical energy.In terms of power production,this would be around 1655 MWh annually.The evaluation is carried out using the MCNP5 Monte Carlo radiation transport code and FEDNL 2.1 nuclear cross section data.The HCSB TBM neutronic performance demonstrates the tritium production capability and high heat deposition.

    • 摘要: Argon and xenon are both attractive working gas for low voltage ionization chamber(LVIC),which is a promising candidate for ITER X-ray detectors.In this work,the performances of Arfilling LVIC(Ar-LVIC)and Xe-filling LVIC(Xe-LVIC)as well as the impacts of operation parameters were investigated.Saturation curves of Ar-LVIC and Xe-LVIC with pressure from 0.4 to 1.2 bar were measured with a tungsten X-ray source.The minimum voltage of saturation region(V_(min))of Ar-LVIC and Xe-LVIC,the relationship between V_(min)and saturation current,the ideal operating voltage in ITER and impacts of pressure on saturation current were studied.It was found that Ar-LVIC had smaller V_(min)and saturation currents which decreased with the drop of pressure from 1.2 to 0.4 bar;Xe-LVIC had larger V_(min)and saturation currents which did not obviously decrease with the same pressure drop.It is envisaged that ITER can take advantage of the larger saturation current and lower pressure of Xe-LVIC in the non-nuclear operation phase,and flexibility of pressure and low sensitivity to neutron/gamma radiation of Ar-LVIC in the nuclear operation phase.
