前沿科技公司 (FTC) offers the design and fabrication of cold-pressed Antimony-Beryllium (SbBe) pellets for nuclear start-up rod assemblies in nuclear plants and fuel scanners in nuclear applications.
All pellets are produced per user-supplied specifications. FTC can accommodate prototype-to-production volume.
什么是锑铍(Sb-Be)?
Antimony is a lustrous semi-metallic chemical element with the atomic number 51 and symbol Sb. It is relatively rare and is typically found in nature in its sulfide form stibnite (Sb2S3). 当它处于纯净状态时, 锑要么是易碎的, hard metallic material or a non-metallic gray powder. The antimony element is not affected by alkalis or dilute acid, and does not conduct heat or electricity well. It can be alloyed with other metals to enhance their strength.
Beryllium is a divalent chemical element with the atomic number 4 and symbol Be. It is a rare element and occurs in nature only when combined with other elements. When not combined with other elements, beryllium is gray, brittle, and strong, but lightweight. It can be found in a variety of beryl gemstones, including emerald, heliodor, and aquamarine.
When the elements are joined, antimony-beryllium (Sb-Be) acts as a secondary source of neutrons. 不像初级中子源, 比如hg0086体育-252, antimony-beryllium neutron sources don’t spontaneously emit neutrons. The antimony component of Sb-Be must be irradiated, which causes it to emit gamma rays. This in turn forces neutrons from the beryllium component, creating a secondary source of neutron emissions. Secondary sources are typically housed in source rod assemblies. Although they are initially non-radioactive, Sb-Be pellets require only one cycle of core irradiation to become an antimony-beryllium neutron source.
应用程序 of Antimony-Beryllium (Sb-Be)
Antimony-beryllium neutron sources have a wide range of uses in nuclear power arrays and elemental analysis applications. The most common applications that incorporate Sb-Be sources include:
核启动棒
Sb-Be neutron sources are sometimes incorporated into 核反应堆中的启动棒. Startup rods are placed in the core reactor with fuel rods to initiate and control nuclear fission. 除了 to reactor shutdowns and startups, nuclear startup rods are also used for power control, 轴向补偿, 以及紧急停机.
中子活化分析
Sb-Be中子源用于 中子活化分析, a process that uses neutron bombardment to determine the elemental composition of a range of materials. When bombarded with neutrons, elements create radioactive isotopes. The radioactive emissions from these isotopes are analyzed to determine the concentration of elements within the sample. NAA is particularly useful because it does not cause physical damage to the sample. 除了, NAA can be used to determine the level of activity in a radioactive material.
小型模块化反应堆(SMRs)
小足迹核反应堆, also known as 小型模块化反应堆(SMRs) are currently in development for use in power generators, 工艺热应用, 海水淡化业务, 以及其他工业应用. They are highly advanced nuclear reactors designed to produce clean nuclear power from tens to hundreds of megawatts. 类似于大型核反应堆, SMRs will require a controlled initiator of nuclear fission, 比如启动杆.
Advantages of Antimony-Beryllium (Sb-Be) Pellets
Antimony-beryllium pellets offer unique advantages over other neutron sources because of their ability to absorb radiation. When placed in a reactor alongside neutron sources or in the core of a reactor, Sb-Be pellets absorb radiation and neutrons, allowing operators to quickly reduce the radiation in the reactor for repairs, 维护, 或者拆卸和更换燃料棒. When the rods are replaced in the core reactor, the Sb-Be pellets are still irradiated and can act as a neutron source to initiate fission and restart the reactor. 除了, Sb-Be pellets can be used to restart a reactor after it has been down and the neutron sources have decayed.
