Daim ntawv thov ntawm lub tshuab nqus tsev cov tshuab hluav taws xob nuclear khoom raug tsim
May 17, 2019| Daim ntawv thov ntawm lub tshuab nqus tsev cov tshuab hluav taws xob nuclear khoom raug tsim
Hais txog kev siv lub tshuab nqus tsev technology hauv nuclear fais fab, peb to taub daim ntawv thov ntawm lub tshuab nqus tsev cov cuab yeej hluav taws xob nuclear khoom tsim.
Nuclear fais fab systems yog txoj thiab loj heev, thiab yuav tsum tau siv sij hawm ntev hauv kev kub ceev. Daim ntawv thov cov tshuab nqus tsev yog kev koom tes hauv cov khoom siv roj thiab kev tswj cov hlua, kev kuaj pom nyob rau hauv cov txheej txheem ntawm kev tsim khoom, thiab cov khoom siv ntawm cov khoom siv tshwj xeeb.
Thaum lub tshuab nqus tsev twj siv hluav taws xob ntsaws qhia txog cov uranium kev txhawb nqa rau nuclear fais fab, cov uranium uas muaj kev txhawb zog nrog kev pab cuam ntawm lub tshuab nqus tsev yog thaum kawg yuav ua rau uranium dioxide ceramic roj. Tus txheej txheem, yuav ntxiv cov uranium hexafluoride soluble hauv dej tom qab siv lub xauv dej, dua li ntawm 1.3 * 10 ^ 1 pa nyob hauv lub tshuab nqus tsev nqus dej thiab ntxuav, ua ntawm uranium oxide, thiab kho tom qab kub thiab nqus dej, tho, , ua cov roj cua.
Qhov no tsuas yog qee hom roj hom kev npaj roj, ntau hom kev fais fab, qhov yuav tsum tau muaj roj caij sib txawv, tiam sis kev tsim khoom tsim yuav tsum tau nqus cov txheej txheem, xws li hlau txhuam yuav tsum muaj nyob rau hauv 1.3 * 10 ^ - 2 pa , nyob rau hauv qhov mob ntawm 1400 ℃ , nyob rau hauv tshwj xeeb nqus nqus tsev taws ua kom lub qhov cub kom huv, rov mus rau cov hlau phom. Plutonium nyob rau hauv lub vas nthiv reactor roj ntsiab yog cov co toxic, yog li cov roj sib tov yuav tsum tau ntim rau hauv lub tshuab nqus tsev vacuum tom qab sintering, chav tsev uas siv cov hnab looj tes hauv lub hnab yuav tsum tau nqus, thiab ntxiv rau.
Cov hlua tswj kev siv yog siv nqus cov pa dej ntau hauv cov reactor, tswj cov tshuaj tiv thaiv, thiab tuav ib qhov nqi ntawm lub hwj chim. Kev tswj cov pas pellets feem ntau yog siv boron carbide, uas yuav poob rau hauv huab cua. Yog li, qhov kev npaj ntawm boron carbide pellets yuav tsum nqus dej kom huv thiab ces muab ntim rau hauv ib lub iav tshwjxeeb rau lub tshuab nqus tsev vacuum. Kev tswj tus pas nrig kuj yuav tsum tau nyob rau hauv tus txheej txheem ntawm kev tsim txoj hlua kab yas nqus, haus luam yeeb nyob rau hauv lub pellet tom qab 1.3 * 10 ^ 1 pa, thiab qhov chaw foob pob hlau.
Ces muaj lub tshuab nqus tsev los ntawm lub tshuab hluav taws xob hluav taws xob. Tiv thaiv kom tsis muaj hluav taws xob yog qhov tseem ceeb tshaj plaws ntawm cov hluav taws xob nuclear khoom. Yog li ntawd, txhua yam khoom siv yuav tsum muaj kev sib tw ua kom zoo, thiab kev nqus nqus kom paub tseeb yuav tsum yog thaum raug. Lub leakage ntawm cov hluav taws xob nuclear cov qauv yuav tsum yog 1.3 * 10 ^ - pa 6 L / s. Tam sim no, nuclear cov cuab yeej hluav taws xob kuj muaj tshwj xeeb helium los detectors thiab suction nozzles rau xaim paub tseeb nyob rau hauv loj ntim.
Lwm cov ntaub ntawv tsim muaj cov ntaub ntawv siv lub tshuab nqus tsev, lub tshuab nqus tsev twj siv lub tshuab nqus hlau piv txwv: piv txwv li, cov pa roj carbon dioxide yog siv hauv nuclear zog cog khib nyiab kho, thiab cov activated carbon siv nyob rau hauv nuclear fais fab nroj yog feem ntau cov tshuaj hauv cov khoom nqus nqus tsev, cov activated carbon tau qhov ua tau zoo heev; Cov roj kub txias reactor roj caij cladding siv impermeable graphite, xav tau graphite hauv lub tshuab nqus tsev rau 1000 ℃ los yog li ntawd thiab kis mus rau hauv cov pa roj carbon monolithic pyrolytic, ua rau cov nplaim ntawm lub graphite muaj xim txheej, nqes tau pa; Zirconium thiab nws cov tshuaj txhuam tau ua tiav hauv lub tshuab nqus tsev vim tias lawv hnov mob yooj yim nrog cov pa oxygen, nitrogen thiab hydrogen hauv cov pa.
