Video: Nws yeej tsis tshwm sim, thiab ntawm no yog dua! Rosatom tau txais nickel-63 isotope rau "nuclear roj teeb"

Puas yog nws tsis ntev los tos cov roj teeb atomic? Thawj thawj zaug hauv lawv cov keeb kwm, Lavxias teb sab kws tshawb fawb nuclear tau siv cov roj centrifuges los txhawb cov xov tooj cua isotope nickel-63, uas tuaj yeem siv los tsim lub npe hu ua "nuclear roj teeb", kev pabcuam xovxwm ntawm TVEL Fuel Company (ib feem ntawm Rosatom) qhia.
"Nyob ntawm Electrochemical Plant nyob rau hauv lub nroog ntawm Zelenogorsk, Krasnoyarsk Territory (JSC PO EKhZ; ib feem ntawm TVEL), thawj zaug nyob rau hauv lub keeb kwm ntawm lub nuclear kev lag luam, cov roj centrifuge txoj kev ntawm lub radioactive isotope nickel-63 tau enriched rau. ntau dua 69%, "cov lus hais.
Cov xov tooj cua isotope nickel-63, uas tsis muaj nyob hauv cov xwm txheej, muaj cov khoom tshwj xeeb ntawm cov hluav taws xob beta tsis muaj teeb meem gamma.
Cov nickel-63 isotope tau pib tsim los ntawm irradiating qhov ruaj khov nickel-62 isotope nyob rau hauv IVV-2M kev tshawb fawb reactor ntawm lub koom haum ntawm Reactor Materials JSC (ib feem ntawm scientific division of Rosatom). Ntawm lub koom haum V. G. Khlopin Radium, uas tseem yog ib feem ntawm kev faib kev tshawb fawb ntawm Rosatom, cov khoom tau raug ntxuav thiab ua haujlwm roj tau tsim rau lub cascade ntawm roj centrifuges ntawm PA EKhZ.
Nickel-63 yog dab tsi?
Ib theem siab ntawm enrichment rau cov nickel-63 isotope yog tsim nyog rau kev loj hlob ntawm lub zog mus sij hawm ntev qhov chaw, zus tau tej cov uas yog npaj los tsim los ntawm Rosatom ntawm ib tug ntawm nws cov lag luam, daim ntawv qhia hais tias. Compact "atomic batteries" nrog lub neej kev pab txog li 50 xyoo yog qhov xav tau zoo hauv cov khoom siv thiab cov tshuab uas hloov cov khoom siv hluav taws xob nyuaj, kim, lossis tsis zoo. Cov cheeb tsam uas muaj peev xwm ntawm kev siv cov roj teeb zoo li no yog qhov chaw thev naus laus zis, tshuaj, khoom siv sib txuas lus, cov khoom lag luam ntawm cov tub rog-kev lag luam complex, industrial thiab infrastructure chaw.
"Nyob rau xyoo 2019, cov kws tshaj lij ntawm PO EKhZ, nyob rau hauv lub moj khaum ntawm kev tshawb fawb thiab kev loj hlob tsis tu ncua, npaj kom ua tiav kev nplua nuj nyob hauv nickel-63 isotope ntawm ntau dua 80%. irradiated nyob rau hauv RBMK-1000 fais fab reactor ntawm Leningrad NPP.", - cov lus hais.
Konstantin Vergazov, tus lwm thawj coj loj ntawm TVEL JSC rau kev tshawb fawb thiab kev ua haujlwm, thev naus laus zis thiab kev ua haujlwm zoo, ntseeg hais tias kev sib cais ntawm centrifugal ntawm radioisotopes yog thaj chaw muaj kev vam meej uas qhib kev lag luam tshiab rau kev lag luam nuclear. "Ntxiv rau qhov tau txais nickel-63, Electrochemical Plant twb muaj peev xwm tsim tau cov xov tooj cua zoo heev krypton-85 thiab carbon-14. Cov peev txheej ntawm beta hluav taws xob raws li krypton-85 yog siv los ntsuas qhov tseeb hauv metrology, thiab cov khoom siv nrog ib tug Cov ntsiab lus carbon-14 yog qhov tseem ceeb ntawm kev kawm txog cov metabolism ntawm cov tshuaj tshiab thiab tshuaj pleev ib ce ", - cov lus ntawm Vergazov tau hais hauv cov lus ntawm kev pabcuam xovxwm ntawm TVEL lub tuam txhab.
About TVEL
TVEL Roj Lub Tuam Txhab ntawm Rosatom suav nrog cov lag luam rau kev tsim cov roj hluav taws xob nuclear, kev hloov pauv thiab ua kom muaj txiaj ntsig ntawm uranium, tsim cov roj centrifuges, nrog rau cov koom haum tshawb fawb thiab kev tsim kho. Nws tsuas yog tus xa khoom ntawm cov roj nuclear rau Lavxias teb sab nuclear fais fab nroj tsuag thiab muab cov roj nuclear rau 72 lub zog reactors nyob rau hauv 14 lub teb chaws, kev tshawb fawb reactors nyob rau yim lub teb chaws ntawm lub ntiaj teb no, raws li zoo raws li thauj reactors ntawm Lavxias teb sab nuclear fleet.
Keeb kwm ntawm qhov teeb meem
Nov yog xov xwm los ntawm 2015
Thiab ntawm no yog cov xov xwm uas tau tawm ib xyoos thiab ib nrab dhau los:
Thiab thaum kawg, kev tawm tswv yim ntawm cov xov xwm tam sim no:
Pom zoo:
Dab tsi yog qhov tshwm sim ntawm kev ua tub rog raug mob? Peb pawg ntawm qhov hnyav thiab qhov tshwm sim
Concussion tsis tau suav hais tias yog ib qho kev raug mob tshwj xeeb kom txog rau thaum Tsov Rog Ntiaj Teb Zaum II. Thawj zaug, nws tau raug xaiv los ua ib qho kev sib cais ntawm qhov txhab los ntawm cov kws kho mob tub rog Soviet. Ua ntej ntawm tag nrho cov, lawv tau ua li no ib kauj ruam vim yog lub fact tias tus naj npawb ntawm cov tub rog nrog qhov kev raug mob no nyob rau hauv tej yam kev mob ntawm tag nrho cov tsov rog yog tas li loj hlob. Yog li dab tsi tiag tiag yog concussion thiab yog vim li cas nws thiaj li txaus ntshai rau ib tug neeg?
LEEJ TWG tau coj nrog nws saum txoj hmoo - thiab qhov ntawd yog qhov tshwm sim ntawm nws
Nws qhov kev kuaj mob zoo li kab lus. Mitochondrial kab mob ntawm cov leeg nqaij thiab lub paj hlwb presupposes dementia, kev kawm tsis taus, maj mam fading ntawm lub cev nqaij daim tawv, thiab ua kom tuag tes tuag taw. Cov me nyuam zoo li no nyob ntev txog li 11 xyoos
Cov roj teeb hemp yog 8 npaug ntau dua li cov roj teeb lithium-ion
Raws li koj paub, lub legendary Ford Model T tsheb khiav ntawm biofuels raws li hemp, thiab kuj suav nrog biopolymer cov ntaub ntawv tsim siv cov nroj tsuag no. Niaj hnub no, cov tsheb uas muaj lub tshuab hluav taws xob sab hauv tau raug hloov los ntawm cov tsheb hluav taws xob niaj hnub nrog cov roj teeb. Thiab tsis ntev los no nws tau pom tias cov hlwb ua los ntawm hemp muaj ntau npaum li 8 npaug ntau dua lithium-ion
Euro roj yog pheej yig dua li cov roj hauv tsev, yuav tsum tshwm sim ntawm cov chaw nres tsheb roj
Roj av los ntawm Tebchaws Europe tuaj yeem tshwm sim ntawm cov chaw nres tsheb roj hauv Lavxias. Peb yuav tsis tham txog qhov zoo, tab sis nyob rau hauv cov nqe lus ntawm tus nqi, nws yog ntau txaus nyiam tshaj li domestic. Ntau npaum li ntawd koj tuaj yeem nruab cov neeg hais lus cais los ntawm lwm hom - "Los ntawm Tebchaws Europe". Thiab yuav tsis tas yuav tham txog additives thiab lwm yam txuj ci tseem ceeb uas yog supposedly saturated nrog hwm hom ntawm Lavxias teb sab roj av. Tag nrho cov txiaj ntsig no yuav ploj mus tiv thaiv keeb kwm yav dhau ntawm tus nqi ntawm cov roj txawv teb chaws
Kev poob ntawm cov nqi roj tsis yog qhov ua rau lub cev qhuav dej ntawm cov khw muag khoom, tab sis yog qhov tshwm sim
Niaj hnub no peb yuav tham txog cov nqi roj thiab tag nrho cov kev txav uas tshwm sim nyob ib puag ncig lawv. Tab sis ua ntej qhov kev sib tham tseem ceeb, kuv nyuam qhuav ua nws tus cwj pwm ua ntej kho qhov tseeb. Vim tias muaj qee cov neeg muaj txiaj ntsig zoo tshaj plaws uas tswj hwm lawv tus kheej ncaj qha rau hauv ob kab lus nyob ib sab
