PJSC Novosibirsk Chemical Concentrates Cog (NCCP) yog lub chaw tsim khoom loj thoob ntiaj teb ntawm cov khoom siv hluav taws xob rau cov chaw tsim hluav taws xob nuclear thiab cov chaw tshawb fawb. Hauv ntau qhov chaw (piv txwv li, kev sib txuas ntawm lithium, kev tsim cov roj uranium), nws tuav txoj haujlwm tseem ceeb hauv kev ua lag luam thoob ntiaj teb. Ib feem ntawm TVEL pab pawg ntawm cov tuam txhab, kev faib cov qauv ntawm Rosatom.

Yam yuav tsum tau muaj rau kev tsim

Thaum 40s lig, tib neeg nkag mus rau lub hnub nyoog nuclear. Tom qab siv cov foob pob atomic los ntawm cov neeg Amelikas hauv Nyij Pooj, Soviet Union tau nkag mus rau hauv kev sib tw caj npab, tsim nws cov riam phom tuag taus. Txawm li cas los xij, lub atom ua haujlwm tsis yog rau kev puas tsuaj xwb. Ua ntej tshaj plaws, nws yog qhov hluav taws xob pheej yig.

Tsoomfwv Soviet hatched cov phiaj xwm los tsim cov chaw tsim hluav taws xob nuclear, tab sis rau lawv ua haujlwm, tshwj xeeb ua tiav (ntxhiab) nuclear roj thiab cov tshuaj lom neeg yuav tsum tau ua. Yuav kom tau txais lawv ntawm kev lag luam, Pawg Thawj Coj hauv 1948 tau txais yuavKev daws teeb meem ntawm kev tsim kho ntawm Novosibirsk Chemical Concentrates Cog.

thawj kauj ruam

Nws tau xav tias kev tsim kho yuav ua tiav ntawm qhov chaw, uas yog thawj zaug npaj rau lub Hoobkas tsheb tshiab. Nws yog ib thaj chaw nyob hauv Kalininsky koog tsev kawm ntawv ntawm Novosibirsk nrog thaj tsam ntawm 240 hectares nrog tsib lub tsev lag luam tsis tiav.

Kev tsim kho ntawm Novosibirsk cog ntawm cov tshuaj concentrates pib hauv 1949. Ntxiv mus, tsis yog tsuas yog cov tsev lag luam thiab cov qauv tsim vaj tsev tsim, tab sis kuj yog cov tsev nyob, cov chaw sib raug zoo thiab kab lis kev cai.

Hnub Ua Haujlwm

Lub hom phiaj tseem ceeb ntawm cov nroj tsuag yog los tsim cov khoom siv roj rau thawj Soviet nuclear fais fab nroj tsuag thiab kev tshawb fawb reactors. Cov txheej txheem thev naus laus zis suav nrog tag nrho cov haujlwm rau tshuaj lom neeg, metallurgical thiab mechanical processing ntawm uranium ore rau hauv cov roj tiav lawm.

Thaum lub sijhawm ntawd, NCCP (Novosibirsk) muaj plaub lub khw tseem ceeb uranium thiab ib lub khw tsim khoom, uas tau muab tso rau hauv kev ua haujlwm hauv xyoo 1950, thiab thawj cov khoom tseem ceeb tau tsim xyoo tom ntej. Thaum pib, theem ntawm kev tsim khoom thiab cov txiaj ntsig tau qis heev. Qhov no yog vim tsis muaj cov cuab yeej tshwj xeeb, qhov tsis zoo thiab tsis yooj yim ntawm cov txheej txheem tsim khoom, kev siv cov khoom kim thiab tshuaj lom neeg, kev siv zog ua haujlwm siab thiab muaj kev phom sij rau kev noj qab haus huv.

Nyob rau hauv ib lub sijhawm luv luv, cov neeg ua haujlwm ntawm Novosibirsk Chemical Concentrates Cog, koom tes nrog cov koom haum kev lag luam, tau ua haujlwm zoo raukev txhim kho thiab kev siv cov txheej txheem thev naus laus zis tshiab thiab kev teeb tsa cov cuab yeej tsim khoom tshiab. Qhov no ua rau nws muaj peev xwm txhim kho qhov zoo ntawm cov khoom thiab cov ntim ntau lawm. Nyob rau hauv lub sij hawm los ntawm 1960 mus rau 1968, qhov piv ntawm cov roj yam tsis xws luag uas tshwm sim thaum lub sij hawm lawv ua hauj lwm nyob rau hauv nuclear reactors poob los ntawm 5.2% mus rau 0.07%. Xyoo 1968, qhov ntim ntawm kev tsim khoom tau nce 7.5 npaug ntawm qhov qub, thiab tus nqi ntawm kev hloov pauv hloov pauv tau txo los ntawm 13.8 npaug.

Txoj kev daws teeb meem tshiab

Tom qab, qhov loj-loj ntawm lithium tau tsim ntawm Novosibirsk Chemical Concentrates Plant. Qhov no yog cov txheej txheem thev naus laus zis uas muaj peev xwm ua cov khoom siv raw kom tau txais cov roj ntsha lithium thiab lithium ntsev, uas tau siv ntau hauv kev lag luam. Cov khoom no tau pab txhawb rau lub tuam txhab nkag mus rau hauv lub ntiaj teb ua lag luam. Kev paub ntau yam hauv kev tuav cov ntaub ntawv fissile tau ua rau nws muaj peev xwm pib tsim cov khoom siv roj thiab cov roj sib txuas rau kev tshawb fawb reactors raws li cov cermet muaj pes tsawg leeg ntawm cov roj nuclear hauv daim ntawv nyias-walled peb txheej kav.

Nyob rau xyoo 1970 thiab 1980s, NZHK hauv Novosibirsk tau nthuav dav nws cov haujlwm hauv kev tsim cov roj rau cov chaw tsim hluav taws xob nuclear. Nws yog lub sijhawm ntawm kev loj hlob sai ntawm Soviet nuclear fais fab kev lag luam. Xyoo 1980, cov nroj tsuag tau teeb tsa cov cuab yeej siv rau kev tsim cov roj ntau thiab cov khoom siv roj rau cov hluav taws xob siab ntawm VVER-1000 series. Xyoo 1997, pab pawg tau tsim thawj pawg roj sib dhos rau VVER-440.

Hnub no

NCCP cov khoom lag luam muaj kev sib txawv tas li ob qho tib si hauv nuclear thiab non-nuclear sectors. Piv txwv li, nyob rau hauv 2006 cov nroj tsuag muab tso rau hauv lub lag luam thawj kab rau zus tau tej cov zeolite catalysts, uas yog siv rau cov fractionation ntawm hydrocarbons (roj thiab gases). Xyoo 2011, lub tuam txhab pib tsim cov uranium-aluminium rods, uas yog siv los tsim kho isotopes.

Tam sim no, lub Hoobkas tau koom nrog ntau lawm:

• Uranium tebchaw.
• Lithium (xws li lithium-7), nws cov tebchaw.
• Zeolite catalysts.
• Nuclear roj.
• Cov pa roj carbon monoxide (oxygen, hydrogen).

Lub tuam txhab txuas ntxiv txhim kho dynamically. Cov tub ua lag luam muaj kev txaus siab rau qhov sib koom ntawm Novosibirsk Chemical Concentrates Plant. Tam sim no, PJSC NCCP yog tus koom tes ntawm TVEL Roj Tuam Txhab, uas tshwj xeeb hauv kev tshawb fawb uranium, tsim thiab muab cov roj nuclear rau ntau lub zog reactors.
