本発明は、ＵＦ６シリンダから液サンプルを採取する方
法に係シ、一定量採取するためにシリンダとサンプラを
接続する配管の途中に定められた容積の計量シリンダを
備えた液サンプリング法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for collecting a liquid sample from a UF6 cylinder, and includes a measuring cylinder with a predetermined volume in the middle of a pipe connecting the cylinder and a sampler in order to collect a certain amount of liquid. It relates to liquid sampling methods.
従来技術としては、例えば配管から落下させる方式はあ
るが、シリンダから液体Ｕ Ｔ” ｅを定量抜取る方式
は国内には無い。As a conventional technique, for example, there is a method in which the liquid is dropped from a pipe, but there is no method in Japan that allows a fixed amount of liquid UT''e to be withdrawn from a cylinder.
本発明の目的は、取扱物質が放射性物質であり種々の取
扱上の制約が入る中で、一定量のサンプルを容易に取り
出す方法全提供することにある。An object of the present invention is to provide a method for easily taking out a certain amount of sample even though the material to be handled is radioactive and there are various handling restrictions.
本発明は、ＵＦ６を液状で取り出す方法であるが、ＵＦ
ａが放射性物質であり、液としてＵＰ。The present invention is a method for extracting UF6 in liquid form.
a is a radioactive substance and is UP as a liquid.
を取り出すだめには、高温、高圧下で行ない、しかも一
定量を安全に取り出すところが要点である。The key to extracting the liquid is to do so under high temperature and pressure, and to extract a certain amount safely.

サンプラー内には、サンプラーの容積より少々い量の液
量を制御して採取する必要がある。First, UF is in a solid state when handled at room temperature, but the density of a solid is about 5 f/cc, while the density of a liquid is about 3 to 4 f/cc; The density decreases as the temperature increases. Due to this physical property,
Avoid overfilling the container in which the sample is stored. For example, if the sample is filled with liquid and solidifies in the sampler, then when the sampler is heated and liquefied, the density will be lower and it will become a liquid seal. It is a danger. In addition, the groove plate 1 is placed in the liquid state in the sampler. If the sampler is filled with UF, a similar situation may occur when the sampler is heated to a temperature higher than that at the time of sampling. For this reason,
It is necessary to control and collect a volume of liquid in the sampler that is slightly smaller than the volume of the sampler.

本発明は上記のような背景から目視不可なる状態下で、
定量のサンプルを取る方式を考案するもので、その原理
を第１図に示す。If you want to limit the amount to be collected, for example, you can use a sampler in a transparent container and visually take a small amount, but the material being handled is radioactive and needs to be heated to make it into a liquid. Due to the high pressure, the sampler must be made of metal for safety reasons, and it would be difficult to adjust the sample amount visually. Below,
A method for taking quantitative samples was devised, and its principle is shown in Figure 1.
第１図１′ｉ１例としてシリンダ内でＵＦ、を加熱。Figure 11'i1Heating UF in a cylinder as an example.

おむねノズルの下しかこ在いため、シリンダを回転して
、ノズルをシリンダ内の液ＵＰ、液面下にする方法を説
明する。The step is to rotate the cylinder in the liquefied state and take a sample of the liquid, but this is because when filling a standard cylinder with a specified amount, if the cylinder is placed horizontally, the U Fe liquid level will generally be below the nozzle. Therefore, we will explain how to rotate the cylinder to bring the nozzle up to or below the liquid level in the cylinder.
〔ステップ１〕

とする。[Step 1] A state in which UF611 is liquefied by heating the cylinder 2 is shown. A piping 7 having a measuring cylinder 8 is attached to the nozzle 6 of the cylinder, and a sampler 10 is attached via a remote control valve 9. In this case, the volumes of the piping 7 and the measuring cylinder 8 are smaller than that of the sampler 10.
〔ステップ２〕
ステップ１で遠隔操作弁９を閉とした状態でシリンダを
回転することによりノズル６がＵＰ。[Step 2] The nozzle 6 is moved up by rotating the cylinder with the remote control valve 9 closed in step 1.

The TF6 is separated from the U F6 held in the piping 7 and the measuring cylinder 8 in the cylinder.

だめシリンダからサンプラへは液体Ｕ Ｆ ６は流れ込
まない。[Step 4] Next, in order to open the remote control valve 9,
Only the amount retained in the pipe 7 and the measuring cylinder 8 separated from the F611 falls into the Templar 10 by gravity. At this time, the nozzle 6 is located above the liquid level of the UF 611 in the cylinder, so the liquid UF 6 does not flow from the cylinder to the sampler.

了する。Using the above method, it is possible to sample a certain amount of liquid UP without overfilling the sampler. After taking a sample in the cylinder tank as described above, the inside of the cylinder tank is cooled, the door of the cylinder tank is opened, and the sampler 10 is separated from the measuring cylinder 8, thereby completing the sample collection.
以下本発明の一実施例を図面によって説明する。An embodiment of the present invention will be described below with reference to the drawings.

プラ内にＵＦ’６の液体をサンプリングする。Figure 2 shows a cylinder 2 housed in a cylinder tank 1 (equipped with a drive sorter 3 for rotating the cylinder, a drive force transmission shaft 4, and a mechanism 5 for transmitting the drive force to the cylinder). A pipe 7 (having a measuring cylinder 8) is attached to the nozzle 6, and a sampler 10 is attached 9 below the pipe 7. In this state, the cylinder tank UF is transferred to the heat exchanger 12.
is heated and immersed, and the liquid UF'6 is sampled in the sampler using the four steps described above.

求範囲を限定するものではない。In Fig. 2, the case where the piping 7 is equipped with the measuring cylinder 8 has been explained. For example, if the volume of the piping 7 is the same as the sampling volume of the sampler, the measuring cylinder 8 is unnecessary; 7 serves as a measuring cylinder, and does not limit the scope of the claims.
