TRIMARAN—H20超低值自動水中氚監(jiān)測系統(tǒng)

 

TRIMARAN—H20超低值自動水中氚監(jiān)測系統(tǒng)的樣品流輸入管線壓力可達(dá)103 kPa.，通過壓力調(diào)節(jié)閥可立即減小到2-3psi，每個調(diào)節(jié)閥配有一個開到100 kPa的壓力釋放閥，因此系統(tǒng)中的壓力從不會超過100 kPa,，這樣操作起來安全，也使得這款儀器成為6級核設(shè)備。

PLC控制

 

Sampling of input lines and control of alarms and pumps is done by PLC unit placed inside of the System Control Module. There is an alarm provided in case of PLC failure as well as manual

override so that the operation can be continued manually until PLC is replaced. Manual operation is a backup system; the unit normally operates in automatic mode.

樣品輸入管線和報警與泵的控制由安裝在系統(tǒng)控制模塊內(nèi)部的PLC裝置完成，一旦PLC或手動超控故障則提供報警，以便在PLC被更換之前手動繼續(xù)操控。手動操作是備用系統(tǒng)，儀器正常自動模式操作。

ADVANTAGES OF PROPORTIONAL COUNTING SYSTEM VERSUS LIQUID SCINTILLATION

與液體閃爍相比，正比計數(shù)系統(tǒng)優(yōu)勢

 

Until recently, the only detectors capable of measuring very low levels of tritium in water were Liquid Scintillation Counting (LSC) based. However, the LSC approach has some obvious disadvantages, such as: the LSC fluid must be constantly refilled at a significant cost in labor, money, and space; LSC fluid is also hazardous material and mixing with tritium results in ’liquid mixed waste,’ which must be carefully stored, transported and disposed of.

直到最近，唯一能夠測量極低水氚的探測器為液閃計數(shù)技術(shù)，然而，液閃方法有明顯不足，如：LSC液體必須持續(xù)續(xù)滿，費工，費錢和占用空間，LSC液體也是有毒物質(zhì)，與氚混合導(dǎo)致 “液體混合廢液”, 廢液必須小心存儲，運輸和降解。

 

 By utilizing proportional counting technology, the user only has to acquire a compact standard steel tank of proportional gas, which will last for more than a month and is available from a variety of suppliers. The P-10 counting gas is 90% Argon and 10% Methane, and is not toxic or combustible. Measurement via this method achieves same or better low-end sensitivity, without having to deal with LSC fluid and waste.

使用正比計數(shù)技術(shù)，用戶需要一個緊致標(biāo)準(zhǔn)的正比氣體鋼容器，可用一個多月，供貨方便，P-10計數(shù)氣體90%氬氣，10%甲烷，無毒不易燃。通過這種方法測量可達(dá)到相同或更好的低值敏感度，而且不用處理LSC液體和廢物。

 

 

SAMPLE ENRICHMENT

樣品濃縮

 

With LSC and proportional counting detectors, Overhoff has pushed tritium detection to the most sensitive limit. However, samples can be so dilute, even with large multi-liter detectors, there are not enough disintegrations per second for good measurements. This issue is overcome by concentrating or enriching the sample,. This may be accomplished using iterative processes to concentrate the tritium in water using phase change or other physical differences (not chemical processes since 1H, 2H, and 3H are chemically identical.) Overhoff scientists have developed their own iterative sample enrichment cycle, creating system sensitivities far beyond other automated flow-through systems.

使用LSC和正比計數(shù)探頭，OVERHOFF已經(jīng)將氚探測推到一個最靈敏的限值，然而，樣品可能太稀釋，即使用多升探測器，也沒有足夠的每秒衰變以達(dá)到良好的測量結(jié)果，這個問題通過濃縮樣品被攻克，可以通過使用相變或其它物理差異（不是化學(xué)過程，因為1H, 2H, 3H化學(xué)性質(zhì)相同）濃縮水中氚來完成。OVERHOFF科學(xué)家已經(jīng)研發(fā)出自己的迭代樣品濃縮循環(huán)，使得系統(tǒng)靈敏度遠(yuǎn)遠(yuǎn)高于其它自動流過式系統(tǒng)。
